ASP.Net >> TraceOutputOptions not honored

I would like my trace entries to have a timestamp so I figured I
could set the properties on the trace listener to accomplish this but THAT
that doesn't see to work .
dim txtListener as System.Diagnostics.TextWriterTraceListener = new
System.Diagnostics.TextWriterTraceListener(sw, "txt_listener")
txtListener.TraceOutputOptions = TraceOptions.DateTime


Log entries don't get any time info when written.

Doc says that these options aren't available for EventLogTraceListener but
there isn't anything restricting TextWriterTraceListener nor should there be
.



Any ideas ?
thanks

ASP.Net >> TraceOutputOptions not honored Hi,

For the built-in TraceListener classes, EventLogTraceListener and
WebPageTraceListener will not use TraceOutputOptions to output additional
content. Following built-in TraceListener classes should honor
TraceOutputOptions correctly:

* DefaultTraceListener
* TextWriterTraceListner
* ConsoleTraceListener
* DelimitedListTraceListener
* XmlWriterTraceListener

However, these additional trace data controlled by TraceOutputOptions will
not be generated if you are directly calling Write() or WriteLine() method.
For these Write* methods, if will output only the message you let them
output, they will not add additional content such as DateTime.

You can use following code snippet to test it:

#Const TRACE = True
Dim txtListener As System.Diagnostics.TextWriterTraceListener = New
System.Diagnostics.TextWriterTraceListener(System.Console.Out,
"txt_listener")
txtListener.TraceOutputOptions = TraceOptions.DateTime
System.Diagnostics.Trace.Listeners.Add(txtListener)
System.Diagnostics.Trace.WriteLine("This message will not add
DateTime.")
System.Diagnostics.Trace.TraceError("This error message will add
DateTime.")

Since you're asking in ASP.NET newsgroup (and based on your previous post
about WebPageTraceListener), I assume you're use System.Diagnostics.Trace
from ASP.NET web application. As I mentioned above, WebPageTraceListner
will not use TraceOutputOptions to output additional content. However, I
think the output generated by ASP.NET TraceContext may have the date time
information you required:

Here's an explanation of the "Trace Information" section contents in the
asp.net trace log:

=========================
Category

A custom trace category that you specified as the first argument in a
trace.Write (or trace.Warn) method call.

Message

A custom trace message that you specified as the second argument in a
Trace.Write (or Trace.Warn) method call.

From First (s)

The time, in seconds, since the request processing was started (a running
total).

From Last (s)

The time, in seconds, since the last message was displayed. This column is
especially helpful for seeing how long individual operations are taking.
=========================

Hope this helps. Please feel free to post here if anything is unclear.

Sincerely,

ASP.Net >> TraceOutputOptions not honored It wasn't clear or even mentioned in the documentation that the traceOptions
are only available when calling traceError,warn or info . Additionally ,
looking at the output I do get with Trace.TraceInfo with DateTime set, it is
not formatted as I would like.
... so it's nice to have all these features but they aren't very useable
so I suppose we will just write our own .

thanks anyway

ASP.Net >> TraceOutputOptions not honored I understand your concerns about the documentation, please feel free to
give your feedback on the MSDN online documentation.

In the meanwhile, if you need help on how to create your own TraceListener,
please don't hesitate to let us know.

Thank you for using MSDN Managed Newsgroup service!
