An Adobe AIR application that brings the ColdFusion 8 documentation to your desktop that is surprising small, easy to use, extremely fast, and built using the Ext JavaScript library.
Get a quick primer on Gears, the open source project by Google that aims to expose new modules and capabilities for the browser that provide general purpose building blocks for web applications to unlock the capabilities of the local machine in a safe manner.

I recently worked on a project that required obtaining the resolution of photograph. The approach I used was to limit the photographs to Jpeg format images only, which I could then use the new imageGetEXIFMetada() function in ColdFusion 8 to obtain the X-Resolution and Y-Resolution tags. Here is a quick summary of some of my findings and problems.

Borrowing some code & ideas from Pete Freitag’s CFIMAGE presentation; this is a rather simple, safe, and easy way to upload photos using a User-Defined Function in ColdFusion. Uploading files is very straight forward in ColdFusion, but I like this function because it takes care of all the little details, so I can concentrate on working with the file afterwards, and moving to the next iteration when programming.

Read MoreOne of the features of the prototype library that I like to use is the Enumerable class. Although highly debatable in regards to the legitimate necessity for such class, I like the simplicity and beauty of using Prototype’s enumerable class.
So, when using Ext as a base library (not using the Prototype adapter) for JavaScript DOM manipulation I looked into the enumeration methods available, such as Ext.each(). Here is a quick overview of how I used Ext.each to traverse members of a collection of HTML nodes. I decided to split this up into main topics; first I will talk about why I like to use the enumerable class, and then show you a simple example of using the Ext.each() method.
Read MoreIf you are using ColdFusion 8’s <cfgrid> tag for a CRUD interface you might be utilizing the editable grid feature or you might be utilizing the <cfwindow> tag. Because of some of the limitations of inline editing, such as the lack of a rich text editor, I am using <cfwindow> for a project and here is how I am setting the title programmatically from the <cfgrid> binding.
