client area topleft point relative to screen

Hello,

http://www.cse.unsw.edu.au/~ywid062/topleft.gif

How do I get that point coordinate, relative to the screen? GetWindowRect gets the edge of the window, not the client area. GetClientRect returns (0,0) as the topleft, which means combining the use of that with GetWindowRect still won't get you anything.

I think im missing something.. please help :)

Thanks in advance
