Recently at work I have been fighting with some major performance issues regarding Regular Expressions running with the RegexOptions.Compile flag set on 64 bit servers. On a Win2008 Server 32 bit everything ran fine, all of our load test came back without any problems. So we then moved to a 64 bit setup and that's when the load test just went south. After some research and some help from David Penton...

I was working on a photogallery for Graffiti-CMS using the jQuery lightbox to display some images. I noticed that the lightbox was rendering funny. As I started looking around the rest of the site that was also using jQuery tabs and the jQuery accordion control I noticed that these controls were also messing up.

If the page is a script, add a handler....

If you have Community Server installed in a virtual directory of the parent site you need to make sure that the Community Server virtual directory is not inheriting the web.config from the parent. So, to fix this just wrap the < system.web > node with this: < location path ="." allowOverride...

I recently ran into an issue with my link buttons not working in Firefox. I was getting a message that said: “theForm is undefined” when I would click the link and then view the error in firebug. They worked fine in IE6/7 but not in Firefox. Originally I thought it had to do with some of the crazy nested lists I had on this Community Server site I was working on. But it turns out that Firefox...

I started working on a project at work using Blend 2. One of the thing I wanted to do was to use an xml datasource for some of my lists. I looked around and could not find very much information on how to do this, I even have the Pro WPF in C# 2008 book, which doesn’t explain it very well either.
