I know this is a basic question, but that's where I am at at the moment. 
The following program works, and opens a main window, loads the dialog, but
unfortunately the dialog is displayed in a separate window, instead of
being associated with the main window.

ie I basically want the dialog to take up all the client space of the first
window, and if I move the main window, the dialog moves with it.

I have already tried the obvious thing of replacing HWND_DESKTOP with hwnd,
but that makes the dialog window disappear!  Any ideas? Thanks + bye. 
Paul.
