[Visual Basic] Overloads Public Shared Sub Fail( _ ByVal message As String, _ ByVal detailMessage As String _ ) [C#] public static void Fail( string message, string detailMessage ); [C++] public: static void Fail( String* message, String* detailMessage ); [JScript] public static function Fail( message : String, detailMessage : String );
The default behavior is to output the message and detailedMessage to a message box when the application is running in a user interface mode, and to the TraceListener instances in the Listeners collection. You can customize this behavior by adding a TraceListener to or removing one from the Listeners collection.
