ScrollWindow( hWnd, nCol, nRow, aRect, aClip )-> <nil>
------------------------------------------------------------------------------


 PARAMETER:

  <hWnd>        Is the handle that identifies the window to be scrolled

  <nCol>        Specifies the number of columns to scroll, given in device
                units. To scroll to the left, this parameter must be a
                negative value

  <nRow>        Specifies the number of rows to scroll, given in device
                units. This parameter must be a negative value to scroll up

  <aRect>       Specifies the rectangle coordinates of client area to be
                scrolled : { nTop, nLeft, nBottom, nRight }

  <aClip>       Specifies the clipping rectangle coordinates to be scrolled



 DESCRIPTION:

  The ScrollWindow function scrolls the contents of a window's client area. 
  If the caret is in the window being scrolled, ScrollWindow automatically
  hides it to prevent it from being erased, then restores the caret after
  the scroll is finished. The caret position is adjusted accordingly if the
  caret rectangle intersects the scroll rectangle. 
  The area uncovered by the ScrollWindow function is not repainted, but it
  is combined into the window's update region. The application will
  eventually receive a WM_PAINT message notifying it that the region needs
  repainting.
