  CWnd* SetFocus();
 
  Remarks
 
  Claims the input focus. The input focus directs all subsequent keyboard
  input to CWnd. The window, if any, that previously had the input focus
  loses it.
 
  The SetFocus member function sends a ◄WM_KILLFOCUS► message to the CWnd
  that loses the input focus and a ◄WM_SETFOCUS► message to the CWnd that
  receives the input focus. It also activates either the CWnd or its
  parent.
 
  If the current CWnd is active but doesn't have the focus (that is, no
  window has the focus), any key pressed will produce the messages
  ◄WM_SYSCHAR►, ◄WM_SYSKEYDOWN►, or ◄WM_SYSKEYUP►.
 
  Return Value
 
  A pointer to the window object that previously had the input focus. It
  is NULL if there is no such window. The returned pointer may be
  temporary and should not be stored.
