I need to capture kernel debug messages (similar to DbgView.exe) and look for a substring
so that I can play a warning tone upon detection. Is there sample code available for this.
Also, does this take a kernel component ( a custom driver to capture kernel messages) or can all of this be done in an app?
Don’t cross post, it’s against the rules that you agreed to when you joined.
Just answered a couple of weeks ago:

This seems like a strange way to solve this problem, why not write a
debugger extension on the host to do something when that output comes by?

Indeed. Kd extensions are actually fairly easy, documentation
notwithstanding, and VERY useful.
Good luck,

This is to work with a driver that cannot be changed. There is no debugger connected when the technician uses this station. I need to implement this in an app or an app plus an auxillary driver if needed.
You could write an ‘application’ using the same API as an extension that
could capture USER messages pretty easily.

Massoud,
one approach could be to use DebugView and log the kernel messages into a file. Then have a second user mode application which looks at this file and scans for the substring on every file change or periodically.

There’s a app called Dbwin32 by Andrew Tucker that does
this. I believe it’s a 32bit port of the original 16bit
dbwin.exe, but googling finds a couple of hits that look
like they may have src.

Wake up, dreamer! Windows no longer uses shared memory for these debug
messages.

OutputDebugString will still use the dbwin shared section (if it’s present).
