  afx_msg void OnHScroll( UINT  nSBCode, UINT  nPos,
                          CScrollBar*  pScrollBar  );
 
  Parameter    Description
 
  <nSBCode>    Specifies a scroll-bar code that indicates the user's
               scrolling request. This parameter can be one of the
               following values:
 
               Value              Description
 
               SB_BOTTOM          Scroll to lower right.
 
               SB_ENDSCROLL       End scroll.
 
               SB_LINEDOWN        Scroll one line down.
 
               SB_LINEUP          Scroll one line up.
 
               SB_PAGEDOWN        Scroll one page down.
 
               SB_PAGEUP          Scroll one page up.
 
               SB_THUMBPOSITION   Scroll to the absolute position. The
                                  current position is provided in <nPos>.
 
               SB_TOP             Scroll to upper left.
 
  <nPos>       Specifies the scroll box position if the scroll-bar code is
               SB_THUMBPOSITION; otherwise, not used.
 
  <pScrollBar> If the control is a scroll bar, contains a pointer to the
               control. If the user clicked a pop-up window's scroll bar,
               this parameter is not used.
 
  Remarks
 
  Called when the user clicks a window's horizontal scroll bar.
 
  The SB_THUMBTRACK notification code typically is used by applications
  that give some feedback while the scroll box is being dragged.
 
  If an application scrolls the contents controlled by the scroll bar, it
  must also reset the position of the scroll box by using the
  ◄SetScrollPos► member function.
 
  This message-handler member function calls the ◄Default► member
  function. Override this member function in your derived class to handle
  the ◄WM_HSCROLL► message.
