Catch Application Exceptions in a Windows Forms Application

You need to handle
the System.Windows.Forms.Application.ThreadException event
for Windows Forms. This article really helped me: http://bytes.com/forum/thread236199.html.

Application.ThreadException += new ThreadExceptionEventHandler(MyCommonExceptionHandlingMethod)

private static void MyCommonExceptionHandlingMethod(object sender, ThreadExceptionEventArgs t)

{

    //Exception handling...

}

AppDomain.UnhandledException and Application.ThreadException.

http://msdn.microsoft.com/en-us/library/system.appdomain.unhandledexception.aspx?cs-save-lang=1&cs-lang=csharp#code-snippet-2

using System;

using System.Security.Permissions;

public class Example

{

   [SecurityPermission(SecurityAction.Demand, Flags=SecurityPermissionFlag.ControlAppDomain)]

   public static void Main()

   {

      AppDomain currentDomain = AppDomain.CurrentDomain;

      currentDomain.UnhandledException += new UnhandledExceptionEventHandler(MyHandler);
try {

         throw new Exception("1");

      } catch (Exception e) {

         Console.WriteLine("Catch clause caught : {0} \n", e.Message);

      }
throw new Exception("2");

   }
static void MyHandler(object sender, UnhandledExceptionEventArgs args)

   {

      Exception e = (Exception) args.ExceptionObject;

      Console.WriteLine("MyHandler caught : " + e.Message);

      Console.WriteLine("Runtime terminating: {0}", args.IsTerminating);

   }

}
