Call Application.OnThreadException(Exception) to raise an exception that will halt processing of the application.

The System.Windows.Forms.Application class has a Application.ThreadException event. You can attach an event handler to this event to do whatever custom processing you need for unhandled exceptions. If you do not attach an event handler, Application.OnThreadException(Exception) will execute the default behavior, which involves displaying a dialog box to inform the user that there has been an error.

Application.OnThreadException(Exception) only implements default exception behavior for unhandled exceptions that occur on threads owned by Windows Forms. Unhandled exceptions on other threads are handled by the AppDomain.UnhandledException event.
