Last week I blogged about a simple proof of concept that I had come up with for compiling Java classes on the fly in ColdFusion. I played a bit more with my proof of concept over the weekend and came up with a bare bones application that does the following: Compiles a directory of '.

I'm sure I'm not the first to ever figure this out, but through a bit of tapping into some underlying Java in CF I devised a method yesterday to compile Java into usable classes on the fly. Given a directory called 'src' that contains one or more '.java' files I call: Which returns an array of structures. Each element contains feedback on the individual files processed.

I'm not sure how in the world I didn't know there was a hot fix released this week, but I just spent a few good hours trying to figure out why CF wouldn't delete an image after I'd resized it. Apparently it is a known bug that has been fixed. Go get it. Do it...

Well it would be part 3, but part 3 is already written and scheduled for later so I'm going with 2.5. Really just a super quick tip for some very impressive performance gains. I don't have concrete evidence other then my 'Wow, that's really a big difference' reaction from taking this one simple step. What is that step? Simply log into your ColdFusion Administrator, go to Settings and check 'Disable CFC Type Checking' (see disclaimer below).

Just finished my session at cf.Objective(). Thanks to everyone who came and participated. I was a bit nervous giving my first public CF preso but I think it went pretty well. Attached is the PowerPoint and sample code.

Dan Vega blogged about our upcoming Cleveland CFUG meeting this Thursday evening, but I wanted to point out to folks that we'll be broadcasting the meeting - which is a preview of my, Brian Meloche and Ray Camden's cf.objective() presentations - via connect. Everyone is encouraged to attend the Connect session to get a free preview of the goodness coming to cf.objective() this year. The connect URL is http://experts.acrobat.

If you haven't seen Joe Rinehart's preview of event generation in MG3 you should check it out. He also shows how MG3 handles SES URLs behind the scenes. The video is truly exciting to me. I can't wait to see more of MG3 at cf.Objective()!!

A few weeks ago Dan Vega blogged about creating a comboxbox (drop down) cell editor for the editable <cfgrid> before he realized that cfgrid supports in cell drop downs. I commented that I'd like to see something like a date picker cell editor and after using Dan's orginal code as inspiration and some hints from this post by Scott Bennett I finally got the thing working.

Yesterday I posted a demo of a UDF that I had been working on to convert HTML (via a URL or raw HTML) to an image. The UDF works OK, but to be honest it's not all that great. Let me quickly explain the process (as some had guessed in the comments on that post yesterday).
