I am trying to write some messages to a text file using Debug.WriteLine("Message").
Here is the code.
Dim Tr As TextWriterTraceListener
Tr = New TextWriterTraceListener(System.IO.File.CreateText("Output1.txt"))
'Tr = New TextWriterTraceListener(System.Console.Out)
Debug.Listeners.Add(Tr)
Debug.WriteLine("Test Message")
I see the output1.txt file being created, but nothing is being written in the file.
How can I fix this problem?
The TextWriterTraceListener buffers data and only writes it when the buffer is full, it is closed/disposed, or Flush() is called:
Dim Tr As TextWriterTraceListener
Tr = New TextWriterTraceListener(System.IO.File.CreateText("Output1.txt"))
'Tr = New TextWriterTraceListener(System.Console.Out)
Debug.Listeners.Add(Tr)
Debug.WriteLine("Test Message")
Tr.Flush()
You need to flush the buffer of the TextWriterTraceListener.
After writing to the trace listener you need to:
Tr.Flush();
See the documentation for Flush on MSDN.
You have to close and dispose the TextWriterTraceListener
Tr.Close()
Tr.Dispose()
