It IS useable for making holes.

lhWnd = FindWindowA(0, _VFP.Caption)

lhRgn = CreateRectRgn(0, 0, _VFP.Width, _VFP.Height)
lhRgn1 = CreateRectRgn(0, 0, _VFP.Width, _VFP.Height)
lhRgn2 = CreateRectRgn(40, 40, _VFP.Width - 40, _VFP.Height - 40)

? CombineRgn(lhRgn, lhRgn1, lhRgn2, 3)

? SetWindowRgn(lhWnd, lhRgn, 1)

Make sure VFP is not maximised and run, their should be a hole. If this does not do what you want then you must use the SetLayeredWindowAttributes API calls (Win2K only)
