override this.Fail : string -> unitPublic Overridable Sub Fail (message As String)Parameters
- message
- String
A message to emit.
Remarks
The default behavior is to display the specified message in a message box when the application is running in a user-interface mode, and to the TraceListener instances in a TraceListenerCollection collection. By default, the TraceListenerCollection collection has an instance of a DefaultTraceListener. You can customize this behavior by adding a TraceListener to or removing one from the collection.
