Probably because the hWnd returned by GetActiveWindow() is not that of your application - you have to save the hWnd at a time where your windows is active and use it. There are entries in the FAQ that may be helpful, but I'm afraid that more detailed exploration on my part would involve billable time, and should not be done through a mechanism like UT.
