Global Exception Handling in C#

by Mark Milec 4/7/2008 9:10:00 AM

I've been using the Application_Error event in ASP.NET as a global exception handler for a while. While looking for a way to implement something similar for Windows Forms I found this post: http://blogs.msdn.com/tom_krueger/archive/2005/02/17/375602.aspx explaining how to use Application.ThreadException to do just that.

I then found out that Application.ThreadException is not available in the .net Compact Framework but as explained here: http://www.danielmoth.com/Blog/2004/12/appdomainunhandledexception-part-1.html, AppDomain.CurrentDomain.UnhandledException can be used to accomplish the same thing.

There are some problems with using AppDomain.CurrentDomain.UnhandledException as explained here: http://www.codinghorror.com/blog/archives/000201.html

I'm using the .NET Compact Framework 2.0 and we have this function and I can use it to catch exceptions, however there are still some GUI thread exceptions that disappear into the message loop, causing Application.Run to exit, but no exceptions are showing up anywhere.

Any advice? I think it is because I need to implement Application.ThreadException, to handle exceptions that are in the GUI thread, however in the CF2.0 it isn't implemented.
