How to: Write Log Messages (Visual Basic)
You can use the
My.Log objects to log information about your application. This example shows how to use the
My.Application.Log.WriteEntry method to log tracing information.
For logging exception information, use the
My.Application.Log.WriteException method; see How to: Log Exceptions.
This example uses the
My.Application.Log.WriteEntry method to write out the trace information.
Public Sub TracingTest(ByVal fileName As String) My.Application.Log.WriteEntry( "Entering TracingTest with argument " & fileName & ".") ' Code to trace goes here. My.Application.Log.WriteEntry( "Exiting TracingTest with argument " & fileName & ".") End Sub
