This was not working for me if I shifted focus to another application.  According to this KB, an application cannot force a window to the foreground while the user is working with another window.  Check this out if you're having trouble: How do you make your application window frontmost?  It contains an example of attaching the LabVIEW window to the process' thread.  So apparently you can force a window to the foreground if you trick the window into the other application's process...?

NI has a pretty good collection of Windows API calls ( http://zone.ni.com/devzone/cda/epd/p/id/4935 ) for more advanced stuff, microsoft MSDN rules the world in windows

Yes - winapi is great. But not for 64 Bit windows...
