3. Make sure real webcam captured by the app (see the list of enumerated MF devices at the start)
4. Wait for capturing to begin, the app should print "Frame number ..."
5. Go to Shutdown options (in Start menu) and choose Sleep or Hibernate
6. Wake up and note that app was crashed

Answer 1

You can see the MS SDK sample CaptureEngineVideoCapture
which is a bit different (CaptureEngine + GUI), but it handles WM_POWERBROADCAST to stop the capture (+ calls PowerSetRequest in Capture.cpp)
