Mirror Driver Sample

NTDEV
1

I built and installed the mirror driver sample that comes with the WDK (6001). I’ve run the reg changes, installed the mirror device using “Add hardware” and etc. I’ve been trying to figure how this code works and have used the following commandlines to test whether I’m doing things correctly.

  1. >ddmlapp.exe -e
  2. >ddmlapp.exe -t
  3. >ddmlapp.exe -w

I don’t really know what the test feature does. When I run the app with option w, a small “Tracking Window Appears” but it (the window) is completely blue, and no matter what I do it nothing ever seems to get updated.

I have a hunch this is not the expected behavior and so I’m wondering what I should do or need to do to get the mirror sample to work as expected?

Thanks in advance.
