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.

I ran into two small hurdles when installing the ColdFusion 8.0.1 updater on my CentOs Linux server.  Here is a quick overview of what I did to get the installer to work.

If 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.

Have you ever wanted to know if a request is coming from an Ajax call or from a standard GET/POST from the browser when using the ColdFusion 8 Ajax functionality?

I will be giving a brief presentation at the local ColdFusion User Group meeting tomorrow on my Ext.CFC that implements the basic features of ColdFusion 8’s <CFGRID> and associated tags.  After releasing the inital CFC I began working on upgrading to the implementation to using the latest Ext 2.x - which required some minor changes.  I have also completed the basic implementation of an editable grid, but want to finish the rest of the form controls available.  So, here is the Ext.CFC upgraded to Ext 2.x with grouping ability.

Jax commented on my last post regarding the load time of my new homepage.  I definitely noticed the load time increase dramatically after implementing ColdFusion 8’s <cfwindow>, <cfdiv>, and <cfform> tags instead of just using Prototype/scriptaculous with a custom JS/CSS file.  Here is a quick summary of what I found.

One of my primary frustrations with the ColdFusion 8 wrappers for Ext is the inability to specify your adapter.  Why must I be forced to use YUI?

A while back I decided that it would be cool to write an Ext CFC that would perform all most of the interfacing between ColdFusion and the Ext JS library.  This was so long ago, that I don’t even remember when I started working on the project in my free time.   I looked at the created date of the file, and it looks like I started this on April 17, 2007 (which might have been before Adobe announced that CF8’s <CFGRID> was to use the Ext library).  Anyways, a fellow ColdFusion programmer, Isaac Sunkes, was asking about using the Ext library without CF8, which brought back the memories of working on this CFC.  So, without further ado…
