HRESULT SetObjectRects( LPCRECT prcPos, LPCRECT prcClip );
See IOleInPlaceObject::SetObjectRects in the Win32 SDK.
Remarks
Called by the container to inform the control that its size and/or position has changed. Updates the control's m_rcPos data member and the control display. Only the part of the control that intersects the clip region is displayed. If a control's display was previously clipped but the clipping has been removed, this function can be called to redraw a full view of the control.
