I think you'll need to have the background program install a low-level keyboard hook via the win32 function SetWindowsHookEx().

Here's the MSDN documentation for SetWindowsHookEX()

http://msdn.microsoft.com/en-us/library/ms644990(v=vs.85).aspx

And here's the KB article on how to do it from C#

This article goes into some detail, too: http://www.codeguru.com/columns/vb/article.php/c4829

I expect your app will get caught by various spyware/anti-virus software as a keyboard logger, though.

Good luck.
