WindowsFormsApplicationBase.OnUnhandledException Method

When overridden in a derived class, allows for code to run when an unhandled exception occurs in the application.

Namespace:  Microsoft.VisualBasic.ApplicationServices
Assembly:  Microsoft.VisualBasic (in Microsoft.VisualBasic.dll)

protected virtual bool OnUnhandledException(
	UnhandledExceptionEventArgs e

Return Value

Type: System.Boolean
A Boolean that indicates whether the UnhandledException event was raised.

By default, this method raises the UnhandledException event as long as a debugger is not attached and the user is handling the UnhandledException event. The event handler can set the ExitApplication property. If ExitApplication is False, or if the event is not handled, the application exits upon return from the exception handler. Otherwise, control of the application is returned to the Windows Forms message loop.
