Question

I have written a utility that monitors for Unhandled Exceptions and then creates a minidump in the event that one happens.

Is there a way, when the event triggers, rather than having the standard messagebox displaying the unhandled exception, could I disable that and display my own with different information?

Thanks.

Handle the Application.ThreadException event to show your own error messages.

You can hook the event at the top of your main method like this:

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

And then you need the Handler method:

static void Application_ThreadException(object sender, System.Threading.ThreadExceptionEventArgs e)
{
    MessageBox.Show(e.Exception.ToString());
}

Edit: You can also handle the AppDomain.UnhandledException event because certain exceptions don’t go through the ThreadException handler.
