How to send trace messages to VS output panel from a native windows service

[Udi Ben Senior]

Hi,
I have a managed windows service that uses a native C++ dll.
I'm launching the VS (2010) debugger using Debugger.Launch() and i'm
able to attach to the service and debug the unmanaged code as well.
When i'm outputting trace messages from the managed code
(System.Diagnostics.Trace) they are displayed in the output window
just fine,
however i couldn't find any way to do the same from the unmanaged
code.
I tried:
_CrtDbgReport()
ATLTRACE()
OutputDebugString()

none of them worked, the messaged were not displayed in the debugger's
output window.
Anyone knows this can be done?
Thanks,
Udi

Debugger, IDE, other tools are, unfortunately for you, *off-topic* here
in a *language* newsgroup.

Your question has nothing to do with the C++ language, the subject of
this newsgroup.

Yes, someone in a Microsoft debugger/IDE forum would. Look on their web
site for "developer tools" (you can start by visiting this page:

Good luck!
