| GetUpdateRect(IntPtr, NativeRectangle, Boolean) | Retrieves the coordinates of the smallest rectangle that completely encloses the update region of the specified window. GetUpdateRect(IntPtr, NativeRectangle, Boolean) retrieves the rectangle in logical coordinates. If there is no update region, GetUpdateRect(IntPtr, NativeRectangle, Boolean) retrieves an empty rectangle (sets all coordinates to zero). |
