App Pool Crashing – Part 2

App Pool Crashing – Part 2

When we left off on this issue, the app pool was crashing at semi-random intervals. After much discussion with Microsoft’s IIS forum, Microsoft’s ASP.Net forum (not much help there), and peer development groups (AZGroups.com primarily), I downloaded and installed IISState.exe, which is a command line monitor (basically) that is placed on the IIS server and listens for app pool issues. It’s far more detailed than Event Log or App Pool logging, providing codes at every POST/GET. Additionally, I tried turning…

App Pool Crashing – Part 1

App Pool Crashing – Part 1

While working on a website that’s designed to run 24 hours a day with no user interaction (an automatically-updating display for users to walk past and see), I came across an interesting phenomenon. Now, the website is designed in ASP.Net 3.5 with AJAX. There’s an UpdatePanel and a Timer, and that’s it for the AJAX portion. The Timer control fires every 10 seconds and fires the UpdatePanel. Simple enough, right? Well, at random instances the website would stop updating and…

Before I begin, please note this is of course…

Problems installing SQL 2008

I had originally installed SQL 2005 Express on my laptop, and something happened during the installation and it got corrupted. I was unable to uninstall, whether I used Add/Remove programs, ran setup.exe ACTION=uninstall from the command line while in the SQL root path, even if I used msicuu2 and msizap to look for the GUIDs associated with SQL 2005. Nothing worked. I thought installing SQL 2008 Express might “fix” or overwrite something and then get me the latest version to…

Setting a Silverlight slider control at initialization

Setting a Silverlight slider control at initialization

I recently ran into a problem where I needed a Silverlight slider control pre-populated with a specific value when the page loaded, but if you use the slider`s ValueChanged event in the code behind file, it dies. Why? Because as the page loads and initializes, the code behind is trying to run and the slider control hasn`t finished being created yet. Putting the values I wanted them to start at worked fine, as long as you put them after the…
