Exception Handling

[Bala Nagarajan]

Hello All,
Is there a way to implement an excpetion handling for an
application domain? I am developing a windows application and i want to
catch any unhandled exceptions. I want to implement something similar to
Application_Error event in ASP.NET that is used to catch all the unhndled
exception.

Thanks

-Bala

Take a look at the 'AppDomain.UnhandledException' event.

You'll want to handle Application.ThreadException in addition to
AppDomain.UnhandledException.

Check out this post from Craig Andre's blog for some good discussion on the
topic.

Hi Bala,

Thanks for your post.

Based on my understanding, you want to apply a global exception handler to
handle all unhandled exceptions in the appdomain, yes?

Yes, .Net provided several global unhandled exception handlers. For
Winform, we can use Application.ThreadException to handle unhandled
exception in main GUI thread. However, .Net defaultly will swallow
exceptions come from non-Main thread. To handle this worker thread
exception, we can add a AppDomain.UnhandledException event handler for
current appdomain.

The good article below shows us a general pattern for handling unexpected
error in .Net application, for your information:
"Unexpected Errors in Managed Applications"

Hope this helps

Put this code into your main entry point of your app.

Application.ThreadException +=new System.Threading.ThreadExceptionEventHandler(Application_ThreadException);

Then add this exception handler method.

private static void Application_ThreadException(object sender, System.Threading.ThreadExceptionEventArgs e)

{

MessageBox.Show(e.Exception.Message + "\r\n" + e.Exception.StackTrace);

MessageBox.Show("Global exception");

}

Of course the event handler can be customized to fit your needs
