The DirectDrawClipper.SetClipList method sets or deletes the clip list used by the DirectDrawSurface7.Blt method on surfaces to which the parent DirectDrawClipper object is attached.
object.SetClipList( _ 
    count As Long, _ 
    rects() as RECT)
If the method fails, it raises an error, and Err.Number can be set to one of the following values:
| DDERR_CLIPPERISUSINGHWND | 
| DDERR_INVALIDCLIPLIST | 
| DDERR_INVALIDOBJECT | 
| DDERR_INVALIDPARAMS | 
| DDERR_OUTOFMEMORY | 
The clip list cannot be set if a window handle is already associated with the DirectDrawClipper object. The DirectDrawSurface7.BltFast method cannot clip.
