Well using Win32 API your window will receive WM_LBUTTONDOWN and WM_LBUTTONUP messages. If the user clicks and drags then these two messages will have different coords. You could write a custom function to create the RECT using those coords.

I don't know of anyhting that does this...but that doesn't mean much
