Backing Up Databases For Offline Storage
by Adrian Senior - 14-Oct-09
Reader Level:

If you are running your own server, then many hats are needed to ensure your clients data is correctly maintained. Everything from the web site and associated files, through to any database that might be used to support the web site needs to be backed up.

In this tutorial we will look at how to efficiently back up your SQL Server Databases and copy them down from the remote server for storing in a separate location. I use hardware within my office for this storage, the databases are copied down to my main machine and then copied across to an external hard drive. This process provides the latest backup in three different locations as well as providing a backup stack of the last thirty days for each database, that should cover all the bases nicely!

ColdFusion Worst Practices Part 2: Abusing Pound Signs (#)
by Ray West - 08-Oct-09
Reader Level:

The pound sign (#) has a special meaning in ColdFusion. It tells the application server to evaluate what is inside the matching pound signs as a variable or an expression. If the value is a variable, or can be treated as an expression or a function, ColdFusion replaces the whole thing with the result of the evaluation.

However, using # signs is not always the best choice. You should not get it the habit of using them where they are not required. Overuse of pound signs can cause the server to work too hard and eventually cause performance issues. In this article we will look at several examples of when not using the # sign is the better choice.

In this series, we will try to highlight some worst practices in the use of ColdFusion syntax, features and options. These are not necessarily the kinds of things that will stop your site from working, but they are things that create bottlenecks, expose security weaknesses, or make your code difficult to read and maintain. In today's installment, we will look at the misuse of the CFOUTPUT tag.

Creating a Form Confirmation Page in ColdFusion
by Tom Muck - 12-Aug-09
Reader Level:

A confirmation page is the last page you reach before submitting a form -- you fill in the fields, click submit, review your information, and then submit one final time. Confirmation pages can be built in different ways. I'll show one method using ColdFusion that utilizes hidden form fields to post to your final action page. I'll leave the bells and whistles to the reader (validation, css, etc) and show the meat of the technique that is being used.

Conditional ColdFusion: Using the IIF Function
by Tom Muck - 23-Feb-09
Reader Level:

There are many uses for conditional statements in programming. The basic principle of conditional programming is that you want to execute code based on a certain condition. The essence of conditional programming is executing code based on the condition being true, with an alternate piece of code being executed if the condition is not true. The IIF() function in ColdFusion provides a shortcut to using an If/else functionality. This article describes the IIF() function.

Useful 404 Pages in ColdFusion

ColdFusion Contact Form in One Easy File - Part 3
by Michael Evangelista - 20-Nov-08
Reader Level:

Michael Evangelista is a freelance web developer, ColdFusion programmer, and owner of a successful web and print design company based in southern Utah. Michael's company, Evangelista Design, has grown from a locally-oriented small business web design company to an international team of designers and ColdFusion developers offering a wide range of online business solutions, including full-service web hosting, custom content management applications, corporate data systems, and more.

In Part 2 of this tutorial, we added several effective spam-prevention methods to our simple contact form, including a simple hidden honeypot field, comparison of submitted values against an easy-to-manage list of banned words and phrases, and a quick check to prevent submission of any html content (containing < and >).

Wired into a single ColdFusion file, we left off with a nifty little spam-blocking, self-submitting, auto-responding, error-handling dynamic gizmo, ready to be battle-tested in the war against spam. You should be able to drop the sample file from Part 2 into any .cfm page, adjust the cfmail settings and other options in the code, and go... it's really that easy!

So... if it works, what's left?

As with any creative or code-related project, there are always aspects that can be cleaned up, simplified and polished. In Part 3, the final part of this series, we'll do some of each:

Streamline our error handling and error message display
Simplify installation and customization options with easy-to-configure scoped variables
Add custom client-side validation using the jQuery JavaScript library

...all in one simple bundle of files that you can insert into any page!

This is the third article in a series about integrating PayPal payments into your ColdFusion Web sites and applications. In the first article we learned about the different PayPal payment services and set up our PayPal account and developer sandbox accounts. The second article introduced the payments workflow, the creation of simple pre-configured buttons and the use of the testing sandbox to test your site or application.

This article is where things get really interesting. So far, everything we've looked at is useful but only to a point. You can create lots of different buttons to sell different products, but everything is static. You can't dynamically build buttons, accumulate products in a PayPal shopping cart or confirm -- and react to -- payments within your site.

This article is where we get into some of this:

ColdFusion Contact Forms in One Easy File - Part 2
by Michael Evangelista - 21-Oct-08
Reader Level:

In Part 1 of this tutorial, we created a simple ColdFusion contact form, and set up some basic checking for a few required values, using validation and a very simple server-side check for an email address.

To process the form contents, we set up two dynamic messages - one to send the email to the site owner, and a custom auto-response 'thank you' message back to the person submitting the form.

Simple, easy, and it works... but we didn't do much to restrict the flow of content, including unwanted junk mail, into our contact form and our customers' inboxes.

In this section of the tutorial (Part 2 of 3), we will add several methods of spam prevention to our simple contact form, including:

Trapping automatic form submission (junk mail bots) with a "Honeypot" field
Preventing html characters '<' & '>'
Blocking a defined list of words and phrases, including common spam terminology and nasty words we don't want in our email
Advanced validation of the email address format

...all in one simple file that you can insert into any page!

ColdFusion and Spry: Part 4
by Keith Dodd - 01-Oct-08
Reader Level:

SPRY is a JavaScript-based framework that provides AJAX-powered dynamic web content. There are other JavaScript libraries available to accomplish similar results (such a JSON, jQuery, etc.) The SPRY library is produced by Adobe Labs, and, as of this writing, is in 1.6.1 release. (SPRY at Adobe Labs.) Although SPRY can be used with other server technologies, such as PHP, ASP.net, etc., SPRY seems to employ techniques that are especially intuitive to the ColdFusion developer.

In Parts I & II, we constructed a simple Picture Gallery with clickable thumbnails that then revealed full-size pics, some with further detail. The SPRY techniques used XML and its source was a static, hand-coded XML file. In Part III, we used one ColdFusion technique to create our XML source (using the tag). In this final part, we will look at another dynamic method of creating XML, as well as suggest other resources to quickly produce XML from data types, such as queries, arrays, etc. Unless your data rarely changes, creating XML dynamically is a more practical approach than hard coding. These latter techniques are not special for SPRY, but can be used anytime you want ColdFusion to produce XML, whether for something like SPRY, direct output to a web page, or Flash/Flex applications.

The CF techniques demonstrated can be used to output XML directly on the fly or provide XML files saved on the hard drive for direct access. For the latter purpose, ColdFusion might be used to update a certain XML file each time the data changes.

Keith Dodd got into web development as a second career following 30 years in public education, with 19 as a middle school principal. With help from friends and a lot of reading, he got into ColdFusion (version 3) and in 2003 was certificated as an Advanced ColdFusion MX Developer. In recent years, he has worked with Flash and the integration of Flash with ColdFusion (with a lot of help from CMX resources). He is just starting to delve into Flex.

Preventing SQL Injection Attacks in ColdFusion
by Tom Muck - 22-Sep-08
Reader Level:

SQL injection is a technique used by hackers to break into your database. SQL Server has been a target because of the vast number of users who do not use it properly. The sad fact is, web developers are assuming all roles in the development of their web sites, and many of them do not have some simple understandings of how security works in a database. A compromised database can destroy your business, or at the very least, give you a few headaches and wasted time restoring from backups. This article will show a few things that will help your web page against attacks.

ColdFusion Contact Forms in One Easy File - Part 1 Free!
by Michael Evangelista - 17-Sep-08
Reader Level:

One of the most common and obvious needs of any professional web developer is the ability to collect information from an HTML form and submit it via email. There are many reasons why this is superior to a simple 'mailto' link, the most important being the ability to hide your actual email address from the ever-more-voracious spambots that plague our online universe (they love to find links like <a href="mailto:me@lotsofspamplease.com"> ... your address becomes a free lunch for the harvester spiders).

In this easy-to-follow tutorial you will learn how to :

Submit a simple html form with any fields you like via email from any ColdFusion page
Double-validate submitted info with <cfform> and server-side checking
Create an automatic custom-formatted mail message
Send the user a custom-formatted auto-responder 'thanks' message
Hide your email address from spambots
Send email so that replying goes to the sender, not back to the web site

...all in one simple <cfinclude> file that you can insert into any page!

This tutorial assumes you have some experience with html form elements, and very basic ColdFusion tags such as <:cfif>, <cfinclude>, <cfparam> and <cfoutput>. A general concept of <cfform> and the 'required' attribute for <cfinput> might also be helpful, but is not required.

Although SPRY can be used with other server technologies, such as PHP, ASP.net, etc., Spry seems to employ techniques that are especially intuitive to the ColdFusion developer.

The Spry parts of this tutorial series (Parts I & II) just scratched the surface of working with Spry. However, they should have given you the basic concepts in a simplified manner, allowing you to go much deeper on your own. When you download Spry you get not only the necessary library, but many examples, as well as Spry widgets to accomplish many interesting effects. These can be invaluable in learning to use Spry.

In Parts I & II, we constructed a simple Picture Gallery with clickable thumbnails that then revealed full-size pics (and some with further detail). The Spry techniques used XML and its source was a static, hand-coded XML file.

In Parts III & IV, we will use ColdFusion techniques to create our XML source. Unless your data rarely changes, creating XML dynamically is a more practical approach than hard coding.

In Part I, we began construction of a simple Picture Gallery that would include an overview, a strip of thumbnails, and a detail area to display a full picture, along with caption and other possible information. We created two Spry datasets, dsOver and dsPics, and used these to accomplish the plan for the Overview and Thumbnail sections illustrated above.

In Part II, we will turn our attention to the Detail area.

In previous articles, we have discussed the way that Microsoft stores dates in SQL Server and Excel and how that can be an advantage and a hindrance as you deal with your data. There is a method to the way that MS products store dates. It allows you to deal with time against an absolute reference rather than being concerned with its formatting (whether US, Euro, or other). But the way ColdFusion's validation functions treat dates can be tricky if you are trying to get some concrete assurance that you are processing valid information.

Adding a JDBC Driver to ColdFusion

ColdFusion ships with JDBC drivers for most of the major databases, however, all JDBC drivers are not created equal. There are good ones and bad ones, and some of the newer drivers will improve performance and stability. In addition, some of the drivers that ship with various versions of ColdFusion have known problems (MySQL comes to mind). Also, there are databases that are not listed in the standard ColdFusion install that you may want to connect to. This article will show the simple process for adding a new driver to the ColdFusion server.

Using CF Tags from CFScript Free!
by Tom Muck - 26-Jun-08
Reader Level:

When working in ColdFusion, you have two basic ways of coding: ColdFusion tags and CFScript. Both are legitimate and both provide certain advantages. With ColdFusion tags, you have a full arsenal of functionality available. With CFScript, you have more basic script operations available, such as looping, setting variables, conditions, and other more mundane tasks. Frequently when writing scripts, however, you need some functionality that is only available to a ColdFusion tag. The more obvious solution is to close the tag, execute your tag, then re-open the tag to resume your coding. We'll talk about another way to approach this situation -- create functions that mimic CF tags.

Using Multiple Application.cfc Files - Part 2
by Tom Muck - 12-Jun-08
Reader Level:

In ColdFusion 7, the Application.cfc file became the application base structure of choice over the Application.cfm file. As you know, the Application.cfm file is the central file in a ColdFusion application that is run before every page in your site. Global functions and variables that are used by the application can be located in this file, or inside files that are included in Application.cfm. Now, with Application.cfc, we can fine-tune the application with application events: onRequestStart, onRequestEnd, onSessionStart, and others. This makes it extremely desirable to use the Application.cfc file over the older Application.cfm file.

Unfortunately, ColdFusion doesn't have the mechanism built into it to run multiple Application.cfc files, as was done with Application.cfm For example, in an administrative section you might have a separate Application.cfm file that includes the main application version of the Application.cfm file but also has additional functionality to protect the administrative directory. Fortunately, there is a way to do the same thing with Application.cfc using inheritance.

Part 1 of this series showed a basic format for extending the Application.cfc in one level of subdirectories. This article, Part 2, will show how to extend even further using cascading Application.cfcs the way that Application.cfm allows cascading, and show one way to convert these old Application.cfm files to Application.cfc

Keeping response times down and interactivity high has, and always will be, two important priorities with web interfaces of any kind. For standard HTML interfaces, AJAX is all the buzz and is great when it's necessary to maintain interaction with live data. But when a static version of the data will do just fine, there's at least one other alternative that you may want to consider….

Modifying Classic ColdFusion Debugging: Part 2

Reader Level:

If you have your own ColdFusion development box, you probably have ColdFusion debugging turned on. I have always used the Classic debugging mode as opposed to Dockable, because I find the popup window takes too long and is too cumbersome to use. However, classic debugging has a few shortfalls. I addressed some with my article on Better Debugging Info for ColdFusion, however that article discussed a completely custom debugging file. Part 1 of this article discussed how to tweak the file used internally by ColdFusion to display debugging results. In that article we expanded arrays and structures for a better debug output. In this article, we'll add some useful query debugging information.

The Mystery of CFC Variables and Properties - Part 4
by Tom Muck - 16-Apr-08
Reader Level:

If you use ColdFusion you should be using ColdFusion Components (CFCs). One of the more perplexing parts of developing CFCs for the beginning ColdFusion developer is how to define variables and properties. The proper use of variables is important for memory consumption and data integrity. You don't want variables hanging around that aren't needed or accessed from areas that they should not be accessed from.

The first part of this series explained some of the differences between local and global variables as they apply to CFCs. The second part of the series showed a simple CFC framework component. Part 3 showed a CFC that extends our base component. The first three parts are usable in any ColdFusion site with any database. Part 4 will focus on SQL Server and show how the tags can be turned into tags, and how the NULL values of the local properties can be used.

If you use ColdFusion you should be using ColdFusion Components (CFCs). One of the more perplexing parts of developing CFCs for the beginning ColdFusion developer is how to define variables and properties. The proper use of variables is important for memory consumption and data integrity. You don't want variables hanging around that aren't needed, or accessed from areas that they should not be accessed from.

The first part of this series explained some of the differences between local and global variables as they apply to CFCs. This second part of the series showed a simple CFC framework component. Part 3 shows a CFC that extends our base component. These first three parts are usable in any ColdFusion site wtih any database. Part 4 will focus on SQL Server.

Quick Shot - Securing Your ColdFusion Session Information
by Ray West - 20-Mar-08
Reader Level:

As we have discussed in other articles, ColdFusion compensates for the stateless nature of web applications by using session variables to track information across the entire time of a user's visit to your site. This allows you to store a user's ID after sign on, for instance, and use it to retrieve information about them from a database or to keep track of information that the user enters while completing a multi page form.

In this article, we are going to go over two simple steps that should lessen the risk of anyone inadvertently providing access to their personal information on your site.

ColdFusion and Exchange Server - Part 3: Updating and Deleting Calendar Events
by Ray West - 14-Mar-08
Reader Level:

Once you have learned to create an appointment in Exchange Server, deleting it is a relatively simple operation. The key to deleting a calendar event is knowing the unique ID that Exchange assigned when you created the event. If you stored the ID returned by the Exchange connection in your database, you just need to retrieve it and use it to send a delete command to the server.

Convert a Querystring into a Struct Using ColdFusion
by Tom Muck - 10-Mar-08
Reader Level:

ColdFusion makes it easy to work with structures like URL variables, form variables, and other types of structures. Why would you want to convert a query string into a struct when the URL struct already contains the URL variable in struct form? Frequently you are presented with a URL string as opposed to a struct containing the URL or form variables. This is where ColdFusion's built-in list functions come to the rescue. With the list function and a loop, it's easy to convert a string into a structure containing members, and even convert the string back into a URL or form struct.

Saving Structures to Client Variables with ColdFusion Free!
by Bill Betournay - 07-Mar-08
Reader Level:

I've always liked using Client variables in ColdFusion. In fact, I probably use them more then I should. The fact that I can set a client variable and not have to worry about passing it around my application in order to use its value is, well, lazily handy for me. However, serious programming involves Queries, Arrays and Structures. Client variables are not typically used to store these types of objects. This article talks about, and shows you how to, set Queries, Arrays and Structures to a Client variable.

URL Tampering is one of the most common ways that people will try to mess with your site. They may try to change a URL String parameter to try and see or change or delete a record that they should not be able to access (which is something you should be trapping for anyway) or they may try to post a form into your site from an external server, allowing them to set whatever they want for hidden form fields.

In this Quickshot tutorial I will show you a quick and simple way to prevent people from accessing content on your site that they shouldn't see.

Ending a Session When the Browser Closes
by Ray West - 27-Feb-08
Reader Level:

Most applications on the web are written as stateless applications, meaning that each page request is basically unaware of anything else that is happening around it. That means that you need to manage the information your pages need to interoperate with each other, like the current account number or what is in a shopping cart. You can do that using the URL string, or cookies or something called session variables.

Creating Custom Toolbars for the ColdFusion 8 Rich Text Editor

Among the great new Ajax features of ColdFusion 8 is a rich text editor that you can easily add to your site, making the collection and display of text much more flexible and attractive. Based on the FCKEditor, the ColdFusion editor is quite full featured for a lightweight object and it allows the formatting of text collected in a form including many HTML features like tables and hyperlinks as well as fonts, styles, emoticons, special characters, text alignment and other things to allow more that just raw text entry into your application.

Quickshot: How to Parse Submitted Form Fields in ColdFusion Free!
by Ray West - 15-Feb-08
Reader Level:

Most of the time, when your site submits a form to the server, you constructed that form so you know what fields to expect on the back side. On occasion, though, you may not know exactly what fields to expect when a form is dynamically created or may only contain data for certain fields. In ColdFusion, you can use a couple of methods to determine what fields exist in a form that has been received and what the data is for those fields.

Using Multiple Application.cfc Files - Part 1
by Tom Muck - 08-Feb-08
Reader Level:

In ColdFusion 7, the Application.cfc file became the application base structure of choice over the Application.cfm file. As you know, the Application.cfm file is the central file in a ColdFusion application that is run before every page in your site. Global functions and variables that are used by the application can be located in this file, or inside files that are included in Application.cfm. Now, with Application.cfc, we can fine-tune the application with application events: onRequestStart, onRequestEnd, onSessionStart, and others. This makes it extremely desirable to use the Application.cfc file over the older Application.cfm file.

Unfortunately, ColdFusion doesn't have the mechanism built into it to run multiple Application.cfc files, as was done with Application.cfm For example, in an administrative section you might have a separate Application.cfm file that includes the main application version of the Application.cfm file but also has additional functionality to protect the administrative directory. Fortunately, there is a way to do the same thing with Application.cfc using inheritance.

Making Stored Procedures Efficient Free!
by Ray West - 08-Feb-08
Reader Level:

As a web application gets larger and needs to handle more traffic, special attention is needed to make sure it is running as efficiently as possible. More often than not, that means taking a look at the way that your data is marshaled from the database. I am constantly amazed at how much effort can be placed in making sure that pages are only so heavy and take X seconds to load on the HTML side, when very little consideration is given to how the database is being accessed.

The two things to remember when dealing with the optimization of your database are minimizing network traffic, and the reuse of execution plans. Both of these are accomplished by the proper use of stored procedures. In this article, we will cover a few tips to help you get the most out of your stored procedures.

Building a CRM/Invoicing System
by Ray West - 01-Feb-08
Reader Level:

Customer Relationship Management has become quite the buzzword lately, and for good reason. No business can succeed without customers, and it has become increasingly necessary for companies to keep a close eye on how they are servicing their existing customers and how they can obtain new ones. Services like Salesforce.com specialize in managing contact with leads, prospects and clients throughout their lifecycle. But they also come at a hefty price.

Many smaller companies could get by with a simpler CRM system, and there are some available in the open source market that might suffice. But there is nothing much available in ColdFusion, so I want to cover over a few articles the basics of creating a CRM and invoicing module that you can use standalone, or add to your existing application. In this first article, we will begin to look at a database structure.

ColdFusion and Exchange Server - Part 1

I have used Thunderbird forever, it seems. We tried Microsoft Exchange Server and Outlook several years ago, But we could never get it to configure quite right with our firewall, and it was a pain to manage, and Outlook and Outlook Express were unreliable, to say the least. I was pretty happy with a simpler mail server and Thunderbird, until two things happened at just about the same time.

My company was expanding, and with that came a larger sales team. There had been requests for Outlook before, but the sales force presented the best argument for needing the features of Exchange server (which most people never realize is a requirement to get all of the fancier features of Outlook). They needed shared calendars and the ability to management meeting invitations, plus better access from multiple locations. Sure there are other products that will allow this, but it seemed like a good time to try Exchange again.

The CFQUERY tag is a versitile tag that is not only for database queries. You can run a CFQUERY query of queries on any valid query result. Results from CFFTP, CFPOP, and CFDIRECTORY, among other tags, are returned as query results. This makes it very easy to do filtering and searching on query results from these different tags. This article will show one use of of the query of queries on a local server directory.

Modifying Classic ColdFusion Debugging: Part 1

If you have your own ColdFusion development box, you probably have ColdFusion debugging turned on. I have always used the Classic debugging mode because I find the popup window debugging mode takes too long and is too cumbersome to use. However, classic debugging has a few shortfalls. I addressed some with my article on Better Debugging for ColdFusion, however that article discussed a completely custom debugging file. The method discussed in this article will show you how to tweak the file used internally by ColdFusion to display debugging results.

Simple Server-Side Form Validation
by Adrian Senior - 02-Jan-08
Reader Level:

Setting up a simple custom server-side form validation is a straightforward process and has the advantage over JavaScript in that it cannot be turned off by the user in order to override your validation.

In this tutorial, we will look at how we can use a combination of ColdFusion, JavaScript and CSS to provide an interactive form validating process. Although we do use a little JavaScript in this process it does not have a bearing on the validation process and is used only to enhance the messaging that is passed to the user.

SQL Group vs. CFOUTPUT GROUP

One of the biggest problems on the Internet these days is spam in the form of comment spam and contact form spam. Blogs are big these days, and many have implemented spam trapping features, however spammers are not all automated robots -- some of the most insidious are real people sitting behind their computer attacking you with their Viagra ads and other assorted garbage. Guestbooks attract spammers like flies. And even contact forms, meant only to go to the site owner, are under attack as well.

This article will show a simple administrative interface to maintain a "bad word" list, and a simple way to prevent the spam from reaching the intended recipient.

We'll assume for this article that you have a user login system and content management system already in place. We'll focus on the functionality to store the content id of the user reading the content.

Using Text Masks in ColdFusion
by Tom Muck - 05-Oct-07

AJAX being all the buzz, Adobe introduced ColdFusion 8 with integration for a bunch of new rich interface features that make your introduction to AJAX a whole lot easier. Of these new features we began to take a look at the cflayout tag. Whether you're wanting to create a one, two or three-column layout or simply create an intranet portal, you will want to take a look at the cflayout tag.

We will continue our series by looking at a couple more attributes of the cflayout tag including the "source" attribute which allows you to populate a region from an external file, "closable" which allows the user to close a region of your layout, how to reference the ColdFusion JavaScript API to allow a user to re-open a region that was closed and some gotchas to look out for when using the cflayout tag.

Creating a Master/Detail Pageset on One Page Using AJAX
by Tom Muck - 19-Sep-07
Reader Level:

Dreamweaver's Master/Detail page set is a handy set of behaviors to use for a drill-down functionality -- display a list of records, and click on a link in the list to view the full record. Using the behaviors, however, you typically create two pages. If you create one page with both, the page will refresh each time you click on a link.

In this tutorial, I'll show how to create one master/detail page that uses some very simple JavaScript to load the details section of the page dynamically using AJAX. This tutorial will apply to PHP, ColdFusion, and ASP, with the concepts applicable to the other available server models that Dreamweaver now supports.

In the first part of this series, I showed how to create a Master/Detail page set using built in Dreamweaver tools, and then add a basic search form querying against one field in the database. What if you want more than that though? The Dreamweaver recordset dialog box allows one filter against one field. This is sometimes useful, but usually not. Typically you might also want to allow other HTML fields into the search. You will want to search allowing multiple search words. Finally, you might want to search multiple database fields. I will address all three situations in this article, which will be targeted to ColdFusion users only.

Creating slide presentations is a common task we have all found ourselves having to do at one time or another. However, the application you have used has probably either been Micorosft's Powerpoint or Apple's Keynote. With the introduction of ColdFusion 8 and the new tag, ColdFusion lets you create dynamic slide presentations from existing source files such as HTML or CFM templates or a mashup of the two. In fact you can even create a slide from an external web page just by specifying the absolute url. Regardless of how you decide to create your slides, the process is simple and we will walk you through creating your first presentation.

Database-Oriented Document Management
by Doug Boude - 21-Aug-07
Reader Level:

Nearly every time the question of storing documents or images in a database comes up, the answer is almost always "don't do it", and for very good reasons. There are those times, however, when it's very much the appropriate thing to do. A clustered server environment can be one such scenario, where deployment of documents and/or images needs to be immediate and not subject to the cluster resynchronization schedule. In order to make an image or document immediately available, we need to utilize a central repository that can be updated in real time: the database.

This article was written by guest author Doug Boude. Having spent four years disarming bombs for the Air Force, Doug Boude is now a Senior Web Application Architect for Fiserv Health in San Antonio, TX. He has been developing with ColdFusion since version 4.0. Doug has written several ColdFusion articles for Fusion Authority.

ColdFusion 8 is the latest and greatest version of ColdFusion and as soon as it hit the Adobe Labs I hurried out to download it and install it. I noticed that there are a few new items that get installed with ColdFusion 8, like .NET integration and LiveCycle Data Services Express edition. So those familiar with installing ColdFusion 7, there are some new settings.

If you have had the pleasure, or pain, of running Windows Vista then you may know that simply installing applications is not really that simple. I will be taking you through installing ColdFusion 8 on Vista with Apache 2 as my web server.

Creating a Table-less Horizontal Looper in ColdFusion
by Tom Muck - 19-Jun-07
Reader Level:

Dreamweaver has a Repeat Region server behavior that loops through your data and allows you to display it in a vertical or horizontal manner. If you want to display the data in a grid pattern, however, it requires a little more effort. Typically, a Horizontal Looper extension or code is used to create a table and put your individual data sections in a table cell. In this tutorial I'll show how to do that using <div> tags and CSS without tables.

This is a version of an article I did for PHP—but for ColdFusion instead. For this tutorial I'll assume you know how to use your database tools to create and manage databases, and how to create connections for ColdFusion.

This is the final article in our series on FusionDebug 2.0, an interactive ColdFusion debugger. While we have looked at configuration, setting breakpoints within a template and stepping thru a CFC to examine the results of a query within the Variables panel, we have not looked at one of the most important functions of FusionDebug.

Variable Introspection is very powerful in that we don't have to use <cfdump> to see what various scoped variables contain. As well as with FusionDebug 2.0 we can also change the values contained within those variables which makes it a great way to test a ColdFusion application and change values during run-time to see how certain sections of code will work.

In this article we will look at a couple of examples on changing a variables value during run-time.

FusionDebug 2.0 - Stepping Through a CFC
by Chaz Chumley - 04-Apr-07
Reader Level:

In our last article we took a look at setting breakpoints within ColdFusion templates using FusionDebug 2.0 an interactive debugger for ColdFusion. While we paused code execution on a single page to view the variables contained within the page, I would bet that we have all built more complex applications that involve the use of ColdFusion Components (CFCs). FusionDebug 2.0 is a great tool in that we can set a breakpoint on any page, including CFCs, UDFs (User Defined Functions) and even custom tags. Knowing this we will take a look at what happens when we set a breakpoint on a query contained with a CFC and how we can view the contents of the query prior to actually outputting the results to browser.

Using the Bell Character—Parsing Lists in ColdFusion
by Tom Muck - 27-Mar-07
Reader Level:

What is the bell character, you might ask? In the old days of computing, before there was surround sound, you could "print" a character to the screen that made a "beep" sound. If you put a bell character (ASCII 7) in a string, it would beep to the screen. These days, the bell character is not used for much...if anything. As a ColdFusion programmer, you can make use of this not-often-used character for different situations. Some lists seem like they are unparseable using regular ColdFusion functions, and some strings might not even seem like lists. This article will show a couple ways to parse otherwise difficult lists.

FusionDebug 2.0 - Setting Breakpoints
by Chaz Chumley - 19-Mar-07
Reader Level:

In this article we will take a look at how to set a breakpoint within FusionDebug 2.0, an interactive ColdFusion debugger by Fusion-Reactor. Breakpoints allow us to stop code execution at a predetermined location within our ColdFusion template, CFC (ColdFusion Component) or custom tag. This is a big plus over having to use to output variables to our page, in that we don't have to allow code execution to complete or unnecessarily abort our template. Once we have our code paused, so to speak, we can inspect all variables of various scope at that particular moment and then let our code finish processing.

Anti-Spam Measures for PHP and ColdFusion - Part 2
by Tom Muck - 14-Mar-07
Reader Level:

Spam, spam, spam, spam. Spammers have taken over the Internet and made it a horrible place to maintain a web site. Spammers have gone beyond simply spamming your email account -- now they are spamming blogs and guestbooks, spamming trackbacks, and spamming signup forms. Even a child's home page with a guestbook for friends is not safe from links for cialis, porn, or web hosting. Obviously these spammers are getting some return from their criminal activity, because they keep doing it. Unfortunately, you can't reach through the computer screen and grab them by the throat to strangle the life out of them. All you can do is put in place some safeguards and try to minimize the attack. Part 2 in this series shows how you can record the IP address of the spammer and block access to your site to that computer in the future. Once again, I'll assume you have familiarity with PHP or ColdFusion basics (databases, inserting and displaying data) and HTML forms.

FusionDebug 2.0 - Configurations Free!
by Chaz Chumley - 02-Mar-07
Reader Level:

Since our last look at installing and configuring FusionDebug, Fusion-Reactor has come out with version 2.0. So your asking "what's new in this version and why should I upgrade?" Well, how about a new standalone installer that gives you Eclipse 3.2, CFEclipse 1.3 and FusionDebug 2.0, all in one fail swoop. They have also included a Server Configuration Wizard that easily modifies the JVM.config (Java Virtual Machine) settings that we looked at in the previous article. Besides a performance improvement of about 10 times faster than before, the most noticable improvement is it's own debug perspective.

So before we go off learning how to set breakpoints and view and modify variables in our code let's take a look at how to quickly set up the new FusionDebug perspective. This is similar to setting up the Eclipse Debug environment that we looked at in our previous article with a lot less choices.

Anti-Spam Measures for PHP and ColdFusion - Part 1
by Tom Muck - 01-Mar-07
Reader Level:

Spam, spam, spam, spam. Spammers have taken over the Internet and made it a horrible place to maintain a web site. Spammers have gone beyond simply spamming your email account -- now they are spamming blogs and guestbooks, spamming trackbacks, and spamming signup forms. Even a child's home page with a guestbook for friends is not safe from links for cialis, porn, or web hosting. Obviously these spammers are getting some return from their criminal activity, because they keep doing it. Unfortunately, you can't reach through the computer screen and grab them by the throat to strangle the life out of them. All you can do is put in place some safeguards and try to minimize the attack.

FusionDebug 1.0 - Configurations Free!
by Chaz Chumley - 12-Feb-07
Reader Level:

If you have been doing ColdFusion development for awhile you have no doubt wished you had an easier way to debug your code instead of using the usual to spit out variables, structs, queries, etc. to a web page. Wouldn't it be nice to set a breakpoint on a line of code and then step thru the web page as it was being rendered? Well now you have just that option. FusionDebug is an interactive ColdFusion MX debugger that plugs into the Eclipse IDE which lets you do just that.

In this series of tutorials we will be looking at how you install the product and create a FusionDebug configuration, set breakpoints in your code that allow for stepping over and into templates, tags and components, change variable values, and watch expressions in the debugger, all in real time.

Implementing a Record Locking System in ColdFusion 7 - Part 2
by Tom Muck - 17-Jan-07
Reader Level:

Most databases have some sort of row-level locking of database records, however when building a web application you need more than that. Picture a scenario where a database will have multiple users and each user could potentially be working on the same record. This can happen in an e-commerce site, where different departments have access to a given order for fulfillment, or in an Intranet site where various employees have access to a given record.

In this article I will show you how to implement a record locking system that relies on the Application.cfc file that was introduced in CF 7. This second part builds upon the files set up in part 1 and creates the record locking system.

In our last article we took a look at building a simple report using the ColdFusion Report Builder. In most cases you may only need a simple report but when it comes to customizing the report fields on the fly we need to consider using input parameters. We will be addressing input parameters in three parts. Our first article will look at adding an input parameter to our existing report's title and then passing that report title from a form. The Second article will look at using input parameters inside a query to filter the data being returned. The third will be using input parameters for conditional formatting, such as hiding or showing parts of a report.

Picture a scenario where a database will have multiple users and each user could potentially be working on the same record. This can happen in an e-commerce site, where different departments have access to a given order for fulfillment, or in an Intranet site where various employees have access to a given record.

In this article I will show you how to implement a record locking system that relies on the Application.cfc file that was introduced in CF 7. Because of the extended setup to get to the locking portion, we'll run this tutorial in two parts. In this first part, we will set up the Application.cfc with a simple login system, and build the results, login, and update pages.

Using a CF Custom Tag for Multiple Tabs
by Tom Muck - 21-Dec-06
Reader Level:

Tabs in a web page are an intuitive way for a user to navigate elements on a page. Using tabs, you can create pages of an article, multi-tab forms, multi-tab pages of links, or other types of pages where there is too much content to fit on one page. Using two ColdFusion custom tags -- one for the tab functionality and one for each individual tab -- you can create a simple way to add tabs to a ColdFusion page. The tab code shown in the article is simple, but can be used to expand on, or you can simply use the techniques shown with your own tab code.

Switching CSS with ColdFusion

Easy Nav for ColdFusion
by Ray West - 01-Nov-06
Reader Level:

In this tutorial I will show you how to develop a navigation handler in ColdFusion that will do the following:

The navigation would be made up of a CSS styled unordered list, <ul>
Each list item, <li>, within the <ul> would be a link to a page within the site
Each <li> would contain an anchor (a) with an href to the target page.
Whichever page the visitor was on at the moment should not show up as a link in the nav, rather it should just show <strong> so as to indicate the current location and avoid self-referencing links
It should be self updating as the navigation changes so that no manual changes are necessary to the code to 'code-around' the links on each target page

ColdFusion Report Builder - Part 1: Exploring the IDE Free!
by Chaz Chumley - 31-Oct-06
Reader Level:

With the introduction of ColdFusion MX 7, Adobe gave developers the ability to create simple to advanced reports using a new tool called ColdFusion Report Builder. While you can still utilize tags such as to generate PDF and FlashPaper reports from existing XHTML content, there are times when your client needs something a little more.

In this series of articles we will be walking you through the interface, simple report layouts, and even advanced topics such as sub reports, parameterization and tips and tricks that every ColdFusion Report writer needs to know.

If you are not familiar with ColdFusion Report Builder then you are in the right place. A quick overview of the product, it is a tool for allowing the user to create banded reports similar to Microsoft Access reports but for ColdFusion. These reports contain definitions with built-in SQL queries, grouping and placement and custom functions and styling that result in a very professional looking report. These ColdFusion Reports are saved with .CFR extension and are then displayed by using the tag.

In Part 1 we will introduce the ColdFusion Report Builder interface to get you familiar where things are laid out.

ColdFusion Code-Behind: Mimicking .NET's Page Directive
by Chaz Chumley - 19-Oct-06
Reader Level:

Microsoft's ASP.NET has given the development community a nice object oriented programming model with its introduction of Code-Behind files. Simply spoken, these are C# or VB.NET files that contain the physical code for wiring up events or actions such as Page Load, button clicks, etc. that the ASP.NET template calls from the very first line of code called a Page Directive.

The power of separating the presentational layout from the actual framework allows developers and designers to work separately from one another. This is very useful in large development teams. Taking a page from this concept we can achieve the same flexibility in ColdFusion by using CFCs and invoking them from the ColdFusion template on every page request.

Join me as I take you through an explanation of how this concept works and hopefully bridge the gap between any Microsoft .NET developers wanting to learn ColdFusion in creating a ColdFusion Code-Behind.

Combine Gets and Posts into the Request Scope
by Chaz Chumley - 06-Oct-06
Reader Level:

Have you ever worked on a large ColdFusion application and had to review previous templates to see whether or not the variables you were trying to process or validate were coming from a FORM submission or from a Query string? We'll don't feel alone, this is a common challenge when developing larger applications. Fortunately we can take advantage of the onRequestStart method within the Application.cfc to eliminate the need to check templates as we explore using the REQUEST scope to process all variables from now on by combining Gets and Posts into the Request scope..

Creating Daily Stats Pages
by Tom Muck - 18-Sep-06
Reader Level:

A stat page can be used for an e-store, blog, ad rotater, or any other type of application where you want to track a specific series of "things" that happen each day. For example, on a blog you might track blog hits. In an e-store, you might track daily sales. For an ad rotator you might track click-throughs.

This article will show how to write a query to group the daily activity in the first section, and how to display that as a graph using ColdFusion in the second section. The article will use SQL Server syntax, but could be adapted to any database. Also, the SQL code is applicable to any server model—not only ColdFusion. This is part 1 of 2.

To my surprise, there has been quite a bit of interest surrounding the open source Eclipse IDE and the ColdFusion plugin known as CFEclipse. Not to say that there are plans to discontinue ColdFusion support in future versions of Dreamweaver, but for the experienced developer there is a growing effort to put some research dollars into the CFEclipse product.

CFEclipse is easy to use and has some great features. We'll examine some of them in this first article in the How To series on CFEclipse.

For those of us building what are known as Web Applications (web sites that are intended to provide advanced application functionality that often replace desktop programs) there have always been a number of limitation in the web server and browser platform that affect the user experience compared to traditional applications. Modern platforms like Flash (and even DHTML) are answering some of those issues on the client side. On the server side, one of the problems has been generating true banded reporting and creating printable reports from what is displayed on screen.

In the last article, we looked at the most basic use of the cfdocument tag to create PDF and FlashPaper documents out of rendered HTML. Without rehashing the product documentation, let’s look at some of the other attributes of the cfdocument tag that affect how your document is presented.

If you've been developing for awhile you may have created some code that you've wanted to reuse and, if you're like me, you've created a folder for CFCs (ColdFusion Components), UDFs (user defined functions) or even a generalized site header and footer. This is great and easily accessible using a cfinclude, cfmodule or invoking a component using cfinvoke or cfobject, until you need to move your folders outside of your web root for whatever reason. This is when everything breaks. Until now...

Extract Links from a Web Page Using ColdFusion
by Tom Muck - 06-Jul-06
Reader Level:

ColdFusion provides a lot of functionality in the form of tags, but some of the more powerful features require a bit of programming knowledge, like the use of regular expressions, XML functions, and the recursive function construct.

This tutorial will show how to use a regular expression to find all given elements in a string, then use an XML function to extract HTML attributes, and use a recursive function (calling a function from within the function until finished) to streamline the coding. In this case, we'll be searching for all links within a page, but the technique could be used to find email addresses, HTML tags, phone numbers, or other formatted pieces of text.

Creating Simple Printed Reports in ColdFusion - Part 1
by Ray West - 27-Jun-06
Reader Level:

For those of us building what are known as Web Applications (web sites that are intended to provide advanced application functionality that often replace desktop programs) there have always been a number of limitation in the web server and browser platform that affect the user experience compared to traditional applications. Modern platforms like Flash (and even DHTML) are answering some of those issues on the client side. On the server side, one of the problems has been generating true banded reporting and creating printable reports from what is displayed on screen.

Sure, there was always Crystal Reports or some third-party program that could help out. But they were always problematic, in my experience. I wanted something built into my language that allowed those very important features to be executed natively. ColdFusion now allows exactly that with a number of new capabilities to provide instant PDF and FlashPaper documents and intricate banded business reporting. In this article, we will look at creating simple printed reports from generated HTML using the cfdocument tag.

Using GUIDs to Verify Registration in ColdFusion: Part 2
by Ray West - 23-Jun-06
Reader Level:

This is Part Two of this article and it explains the use of the verification page to accept a GUID and verify a users account. In the previous article, we created a registration page that accepted a registrants name and email address, generated a strong password, and created and emailed a GUID used to verify that the email address is valid and the person intended to register at your site.

Using GUIDs to Verify Registration in ColdFusion: Part 1
by Ray West - 23-Jun-06
Reader Level:

In a previous article, we talked about Globally Unique IDs (GUIDS) and their use in uniquely identifying records across disconnected databases. Another useful aspect of GUIDs is that they are sufficiently complex enough that they are not easily guessable and care be used for processes like verifying that the information (especially the email address) you received in a user registration is valid. In this article, we will take a look at some code that done just that... plus a little more.

Protecting Sections of a Control Panel by Using Access Levels
by Adrian Senior - 10-Apr-06
Reader Level:

When building administration areas it is often necessary to create multi-level access to the control panel. Often users are re-directed to a page that matches their particular administration rights.

In this tutorial we will look at how we can streamline this process by setting the administration level and implementing the required logic directly in the Application.cfm template. Once this is in place you can then show and hide sections of the control panel to specific users.

Manipulating ID3 Tags - The Updated Version: Part 1
by Arman Danesh - 07-Apr-06
Reader Level:

This is the first of two articles on manipulating ID3 tags from within ColdFusion. ID3 tags provide meta information about MP3 and other music files. This article outlines how to install the necessary Java classes and then outlines the basics of reading ID3 tags.

This article is a revision of an earlier Community MX article. That article used an older version of jd3lib, a Java library for manipulating MP3 files. However, that original version has been discontinued and cannot be downloaded and the new Alpha version has seriously limited functionality which makes it hard to use for the purposes of this article. This update is rewritten to use a newer, more robust Java library.

Making Full Use of Bindings
by Tom Muck - 31-Mar-06
Reader Level:

The Dreamweaver bindings panel has a lot of uses beyond a place to build recordsets and stored procedures. Many people don't realize that when you add session, request, and application variables to the panel manually, you get some visual advantages — the ability to drag items to the page into design view, the ability to use variables as filters, and the ability to add formatting functions to design view.

This article will explore the bindings panel and its advantages. Because we are discussing core Dreamweaver functionality, the article will apply equally to all server models in Dreamweaver, although some server models have better bindings panel support than others.

Using a ColdFusion Custom Tag as a Site Template: Part 4 - JumpStarts
by Tom Muck - 15-Mar-06
Reader Level:

I wrote a series of three articles on how you can use a ColdFusion custom tag to supply the design of every page in your site. Since that time, Community MX has released several JumpStarts — page designs using the latest HTML and CSS techniques to create starting points for your own designs. A JumpStart is also a perfect fit for the use of a ColdFusion custom tag. Heidi Bautista wrote an article about using JumpStarts with ASP.NET master pages — Convert an Existing Site to Use ASP.NET Master Pages and Themes. The ASP.NET master page is very similar in concept to the technique I presented in my series on CF, so this tutorial will cover the same ground for ColdFusion users, using the free North Pole JumpStart.

All About GUIDs
by Ray West - 12-Jan-06
Reader Level:

If you are familiar with databases you have probably used an autonumber field in Access or an Identity column in SQL Server to have the database assign a unique numerical ID to each record that gets inserted into a table. That works great when there is one table in one database responsible for keeping track of those records. But what if you are eBay or Amazon with database servers strewn across the world to increase reliability and availability? What if you need to take records collected by several databases and merge them back into one dataset and still maintain a unique identifier for each record?

Calculating Age In ColdFusion
by Ray West - 06-Jan-06
Reader Level:

Calculating a person’s age from their date of birth seems like a fairly straightforward proposition; subtract the date of birth year from the current year and bam, there is the age. But it is can be trickier than that, especially if your application requires accuracy in the person’s age. Which month they were born in becomes important, as does those pesky little leap years.

Creating a Simple Blog: Part 6
by Tom Muck - 22-Dec-05
Reader Level:

There have been five parts in the series on creating a simple blog. The first five parts focused on creating basic functionality to get a basic blog up and running using simple Dreamweaver design tools. This part will show how to incorporate the functionality into a more complex design — specifically, the latest CMX Jumpstart — Inverness. This tutorial will be equally applicable to ColdFusion, ASP, PHP, ASP.NET, or JSP because we will be using standard Dreamweaver server behaviors to create the blog. In the course of merging the dynamic blog into the design, you'll learn the following about merging content with design in general — how to find repeating items and make them dynamic, how to separate parts of an existing design into a module.

Checking For Strong Passwords in ColdFusion
by Ray West - 16-Dec-05
Reader Level:

Most applications allow users to change their password. It does not do much good to assign a strong password if your user can just change it to ‘fluffy’ at their first opportunity. The function in this article will allow you to check a submitted password to see if it qualifies as strong before allowing it to be saved in the user’s profile.

Generating Strong Passwords in ColdFusion
by Ray West - 15-Dec-05
Reader Level:

If users of your site get their information stolen because they used weak passwords and left themselves open to attack, they will still blame you for the breach. Because of this, you need to seriously consider requiring the use of strong passwords if your site deals with any kind of sensitive information.

This article will show you how to generate strong passwords for your users to protect them and you.

Redirecting Users When Logging In
by Danilo Celic - 12-Dec-05
Reader Level:

While the article Show and Hide Content Based on User Access Level discusses allowing content for multiple access levels (or user groups) to be held on the same page and showing portions of content based upon the user's group, sometimes you need each user group to get sent to different pages (perhaps within different folders). This article discusses how to enhance the existing Log In User Dreamweaver Server Behavior to allow redirecting users to specific pages based upon their access level when they log in.

ColdFusion Tag Clouds
by Joel Martinez - 05-Dec-05
Reader Level:

Wikipedia says about Tag Clouds:

A tag cloud (more traditionally known as a weighted list in the field of visual design) is a visual depiction of content tags used on a website. Often, more frequently used tags are depicted in a larger font or otherwise emphasized, while the displayed order is generally alphabetical. Thus both finding a tag by alphabet and by popularity is possible. Selecting a single tag within a tag cloud will generally lead to a collection of items that are associated with that tag.

The first tag cloud appeared on Flickr, the photo sharing site. That implementation was based on Jim Flanagan's Search Referral Zeitgeist, a visualization of web site referrers. Tag clouds have also been popularised by Technorati, among others.

Jeffrey Zeldman has some thoughts on the subject. Although he's not exactly the biggest proponent of the technique, my purpose here is to simply show you how to create your own. After all, if your client wants a tag cloud, who are you to deny them of it?

Sample code is provided using ColdFusion.

Random Queries (recordsets) For ASP, ColdFusion and PHP
by Danilo Celic - 29-Sep-05
Reader Level:

While most data displays on web sites are in some predetermined, or even user specified order, such as search results of a products table in product name order, it can be quite beneficial to display data randomly, such as random banners, or even random on sale products on the home page. This article will discuss how you can use ASP VBScript with Access and MS SQL Server; PHP with MySQL; and ColdFusion with Access, MS SQL Server and MySQL to generate random results, be it a single random banner from your advertisers, or five random products that are currently on sale.

Many people use SQL Server to store their data, however SQL Server is much more involved than simply a server that allows storage for data. Data Transformation Services (DTS) is part of SQL Server and allows you to import and export data, manipulate files on the system, use FTP, among other things. Using some of SQL Server's built-in DTS functionality along with ColdFusion gives your web application access to some of this functionality.

Part 1 of this series showed how to export data from SQL Server to a CSV file triggered by a ColdFusion page. This part will show how to upload a CSV file to the server and import it into a new table. It will show how to pass information (a filename) to a DTS package from a ColdFusion page and use it in the package.

Testing ColdFusion Forms
by Paul Newman - 16-May-05
Reader Level:

One of the most frequent problems that arises when developing ColdFusion applications is form processing. Often, forms don't work because they don't return the expected results. In this article, you'll learn how to create a form tester page that you can use to view the results of forms submitted via GET and POST. These can be regular HTML forms, or forms created using the cfform tag. You can even test Flash forms in ColdFusion MX 7.

ColdFusion 7: Using ActionScript in Flash Forms
by Paul Newman - 13-Apr-05
Reader Level:

Recently, some of our subscribers have asked how they can manipulate Flash forms — a new feature of ColdFusion MX 7 — using ActionScript. At first glance, support for ActionScript in Flash forms seems limited. However, Flash forms are generated on ColdFusion 7 using a modified version of Flex Server, so if you know a little about Flex and ActionScript, you can get your Flash forms to perform some amazing tricks.

In this article, we're going to use ActionScript to resolve two issues posted on the Community MX Forums: how to create interdependent combo boxes using <cfselect>, and how to set focus to text fields (<cfinput>) in an accordion control.

Simple Search-Engine Friendly URLs
by Arman Danesh - 08-Apr-05
Reader Level:

Often in your ColdFusion applications you are forced to use URL parameters to pass dynamic data between pages. These lead to cumbersome, non-intuitive URLs which are not search-engine-friendly (let alone human-friendly). This article shows how to create ColdFusion applications which use search-engine friendly URLs.

The technique described here has been tested with Apache 1.3 and 2.0 Web servers using the server installation of ColdFusion. Quick testing with the J2EE installation of ColdFusion suggests that this technique may not work as expected. In addition, things are not quite as simple in IIS and this technique won't work without adjustments; I'll probably cover those adjustments in another article in the future.

Building an XML Configuration File For Your ColdFusion 7 Application
by Danny Patterson - 06-Apr-05

Liverpool JumpStart with .NET
by Heidi Bautista - 31-Jan-05
Reader Level:

Ah yes, Liverpool, not only a great JumpStart, but now you can have it with ASP.NET support. In addition to a valid CSS2 and XHTML 1.0 Transitional, WAI and 508 Accessible CSS layout, you also get a dynamic ASP.NET login application. The original release of the Liverpool JumpStart comes bundled with ColdFusion, PHP, and ASP and uses Dreamweaver's built-in User Authentication Server Behaviors. Unfortunately, Dreamweaver doesn't boast similar server behaviors for ASP.NET. To help make up for that lack, here's a special tutorial just for you ASP.NET coders. I've taken the original Liverpool JumpStart pages and added the necessary ASP.NET code. The result: an out-of-the-box ASP.NET login solution combined with a versatile layout. What could be better? :-)

Included in the support files are the CF, ASP and PHP versions of the Liverpool JumpStart. There is a link at the end of the article that will allow you to download just the .NET version if you prefer, as well as a link to download the bundled tutorials that were included with the original Liverpool JumpStart.

The .NET version of Liverpool is available as a no charge upgrade to purchasers of the original Liverpool JumpStart. If you would like to receive the .NET version, please send us an email and we will send you the .NET files. Please be sure to include your name and the email address that is associated with the PayPal account used to make the purchase.

ColdFusion Form Validation
by Danny Patterson - 28-Jan-05
Reader Level:

Form validation is critical to the stability of every web application. Allowing incomplete or invalid data input can cause unexpected errors. There are two methods to perform form validation. The first method is to validate the form's data before it is submitted. In a HTML based web application this would be done using JavaScript. The other method is to validate the form's data on the server. This article will examine a unique feature in ColdFusion that makes server-side form validation extremely easy.

CMX JumpStart: Liverpool
by Adrian Senior - 20-Jan-05
Reader Level:

The Liverpool JumpStart is a little different than what has gone before. It includes a dynamic ColdFusion login application built with Dreamweaver's User Authentication server behaviours. This allows you to quickly and easily edit the login if you need to do so. The login also supports dual access levels and provides default pages for each level to view, along with a logout page to kill the sessions when your users have completed whatever it was they logged in to do.

Also included are login application pages for .NET, PHP and ASP server models.

This JumpsStart contains 12 tutorials, including video lessons on creating a relational database in Access, using Dreamweaver's User Authentication server behavoiurs and setting a datasource via the ColdFusion administrator.

If you prefer not to use server side code, within the download files you will find a static version of the Liverpool JumpStart.

Previous and Next Links for Details Page Stored Procedure
by Tom Muck - 24-Nov-04
Reader Level:

If you have used Dreamweaver to create dynamic pages, you are probably familiar with the Repeat Region and the concept of Next/Previous records. You are probably familiar with the Master/Detail pageset concept -- the Master page contains a table listing your records with links that allow you to drill down into a Details page. The Details page gives you the details about a particular record. Unfortunately, the Details page does not allow you to create the Previous/Next links easily. This is often desirable in a site, such as in a photo album, real estate listing, or other type of list where the user might want to remain on a Detail page and simply cycle through the records rather than go back to the Master page again. This tutorial will show how to create a SQL stored procedure that will supply Previous/Next links to any ColdFusion or ASP page.

Using Conditional Parameters in SQL Server
by Tom Muck - 09-Nov-04
Reader Level:

Most dynamic sites have a database search of some variety. Stored procedures are much more desirable in a web application for many reasons, yet when it comes to performing searches, the stored procedure is not as easily implemented. In a scripted web application, you can create dynamic SQL statements on the fly, putting conditional logic into your WHERE clauses and making the SQL statement fit the situtation. In a stored procedure, it's not so easy. This article will show one way to pass parameters conditionally to your SQL stored procedure. The technique applies to SQL Server, with code provided for ASP and ColdFusion.

This article assumes you know how to create stored procedures, work with the Query Analyzer, and set up your own DSNs.

File Downloads for an E-Store
by Tom Muck - 26-Oct-04
Reader Level:

Pseudo DSN-less Connections in ColdFusion MX
by Danilo Celic - 23-Jul-04
Reader Level:

ColdFusion MX was a great leap forward in many respects, however, one thing that many feel is a step backwards, is that DSN-less connections are no longer allowed. If your client's process was to add their new products in bulk to the shopping cart system by uploading an Access database that contained a table with all the new products in it, or if they collected business cards at their industry convention and needed to upload their Excel spread sheet that stores all the email addresses to add to their eNewsletter, this change in the ColdFusion MX release probably upset your cart a little. The new functionality can basically stop you from connecting to an arbitrary databases, such as the uploaded files in the examples above. However, all is not lost if you are working with Access databases, or Excel files as a source for your data, then you may be able to use what is commonly called a pass through database to connect to your uploaded files. This tutorial will show you how to create pages that upload MDB and XLS files and then output data from those files, all without having a DSN created specifically for the files.

The extension can also be applied to any server-side content that you want to make downloadable in the browser. This is very useful for creating downloadable files of a results display, such as a product list, a sales report, or a search result.

Case Study: Using the New Flash Remoting Classes
by Paul Newman - 15-Jul-04
Reader Level:

Recently, one of our subscribers made me an offer I couldn't refuse. He created a ColdFusion component (CFC) that sends mail using CFMAIL, and queries an Access database. But he was having difficulty getting the data into Flash, and sending the results of a contact form to the CFC. He offered to send me the database, CFC, and FLA source file if I could use the new Flash Remoting classes to tie it all together.

In this article, you'll learn how to call methods on a Flash Remoting service and return the results to Flash MX 2004 components. Includes coverage of the following Flash Remoting classes: Service, PendingCall, RelayResponder, ResultEvent, FaultEvent, Log, RecordSet, DataGlue.

Support Files: ColdFusion component, Microsoft Access database, Flash document, ActionScript file.

Simple Dynamic Recordset Sorting Using Stored Procedures
by Tom Muck - 09-Jul-04
Reader Level:

A stored procedure gives you many benefits when building applications, including web applications using ColdFusion, ASP, and other technologies. They are fast because they are precompiled and they are secure because the database tables are not being accessed directly. One thing that is a little tricky in working with stored procedures is building dynamic queries. You can build a SQL statement as a string within a stored procedure and execute it using the EXEC statement (or xp_executeSQL), but this also defeats one of the purposes of building your functionality into a stored procedure: the statement is not compiled when it is built dynamically. This article shows one way of creating dynamic SQL on the fly while still allowing the stored procedure to be precompiled.

Manipulating ID3 Tags: Part 1
by Arman Danesh - 02-Jul-04
Reader Level:

This is the first of two articles on manipulating ID3 tags from within ColdFusion; ID3 tags provide meta information about MP3 and other music files. This article outlines how to install the necessary Java classes and then outlines the basics of reading ID3 tags. **This article has been updated.

Affiliate Tracking System For ColdFusion
by Tom Muck - 11-Jun-04
Reader Level:

ColdFusion users have an application.cfm file which makes building an application much easier in many respects. The reason is that this file can do a variety of different things because it is always the first file executed no matter what page was requested in your application. You can use this to your advantage in an affiliate tracking application, such as in an e-store. This article will show how to build it.

CMX CF Upload Size Server Behavior
by Bill Horvath - 09-Jun-04
Reader Level:

CMX CF Upload Size allows you to set a maximum file size - in bytes - that a user may upload. If the file they attempt to upload exceeds your limit, they are given a message explaining that their file is too large. If the upload is successful, they will get a message saying the upload was successful. All the server behavior requires is that you have a file field and submit button inside of a form. This Server Behavior is for ColdFusion only.

Creating a Simple Blog Part 4
by Tom Muck - 25-May-04
Reader Level:

One of the frequent questions in the forums is "How do I create a blog?". There are many commercial blog systems out there, and many full-featured blog providers, like Blogger, but you can also create a simple blog using the standard tools of Dreamweaver. This tutorial will be equally applicable to ColdFusion, ASP, PHP, ASP.NET, or JSP because we will be using standard Dreamweaver server behaviors to create the blog. This fourth part of the series will describe how to add categories to the blog by modifying the pages you've already created and also how to display the number of comments on each item.

Better Debug Info for ColdFusion Development
by Tom Muck - 18-May-04
Reader Level:

ColdFusion does not have a lot of functionality to aid in debugging your applications. The built-in debug information that you can access through the ColdFusion administrator gives you some basic information, but if you are using complex objects, structures, or CFCs, you are left without a way to examine these constructs. The technique shown in this article can also be used in a production environment because it can be turned on through a URL variable, and is tied to the user's session.

Limiting Upload File Size in CF
by Bill Horvath - 28-Apr-04
Reader Level:

Even if you're standing right behind someone saying "OK, your upload size is limited to 10 kilobytes", chances are they'll try and upload something larger than that. This tutorial will outline how to prevent a user from uploading a file that exceeds your predetermined file size limitation. We'll also give the user a message explaining what the file size limit is - if they exceed it, and a "File Uploaded" message if they do not.
