     The coordinates are in screen units and are relative to the upper-left 
     corner of the control's client area. 

Rich edit controls: A pointer to a POINTL structure that contains the 
                       horizontal and vertical coordinates. 

Edit controls: The low-order word contains the horizontal coordinate.
               The high-order word contains the vertical coordinate.
