Given a visible, active overlay surface (DDSCAPS_OVERLAY flag set), the DirectDrawSurface7.GetOverlayPosition method returns the display coordinates of the surface.
object.GetOverlayPosition(x As Long, y As Long)
If the method succeeds, it returns the display coordinates of the active overlay surface.
If the method fails, it raises an error, and Err.Number can be set to one of the following values:
DDERR_GENERIC |
DDERR_INVALIDOBJECT |
DDERR_INVALIDPARAMS |
DDERR_INVALIDPOSITION |
DDERR_NOOVERLAYDEST |
DDERR_NOTAOVERLAYSURFACE |
DDERR_OVERLAYNOTVISIBLE |
DDERR_SURFACELOST |
