protected virtual bool OnUnhandledException (Microsoft.VisualBasic.ApplicationServices.UnhandledExceptionEventArgs e);

abstract member OnUnhandledException : Microsoft.VisualBasic.ApplicationServices.UnhandledExceptionEventArgs -> bool

Protected Overridable Function OnUnhandledException (e As UnhandledExceptionEventArgs) As Boolean

Parameters

e: UnhandledExceptionEventArgs

The data for the event.

Returns

Boolean

A Boolean that indicates whether the UnhandledException event was raised.

Remarks

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.
