  BOOL SubclassWindow( HWND hwnd );
 
  Parameter   Description
 
  <hwnd>      A handle to the window.
 
  Remarks
 
  Attaches a window to a CWnd object and replaces the window's WndProc and
  AfxWndProc. It stores the old WndProc in the location returned by
  GetSuperWndProc, which is used for default message processing (see
  CWnd::DefWindowProc). You must override GetSuperWndProcAddr for every
  unique window class to provide a place to store the old WndProc.
 
  The operation of replacing a WndProc with a new one, saving the old one
  and calling it a "super class," is known as "dynamically subclassing" a
  window.
 
  Return Value
 
  TRUE if the function is successful; otherwise, FALSE.
