Re: Tracing to text file in production environment (debug="false")

Ahh, I just figured it out... I wasn't adding my listener to the TRACE
listeners collections, only the DEBUG listeners!

----- 8< -----
'Creates the text file that the trace listener will write to.

Dim myTraceLog As New System.IO.FileStream(User.LogFile,
IO.FileMode.OpenOrCreate)

'Creates the new trace listener
Dim myListener As New TextWriterTraceListener(myTraceLog)

'add a listener
System.Diagnostics.Debug.Listeners.Add(myListener)
System.Diagnostics.Trace.Listeners.Add(myListener)

Thanks, Efran - you pointed me in the right direction - all working great now :)

Cheers,

Ben
