myWriter->Writer = System::Console::Out;
Trace::Listeners->Add( myWriter );
/* Create a listener, which outputs to the console screen, and
* add it to the trace listeners. */
TextWriterTraceListener myWriter = new TextWriterTraceListener();
myWriter.Writer = System.Console.Out;
Trace.Listeners.Add(myWriter);
' Create a listener, which outputs to the console screen, and
' add it to the trace listeners.
Dim myWriter As New TextWriterTraceListener()
myWriter.Writer = System.Console.Out
Trace.Listeners.Add(myWriter)
