发送WM_SETTEXT消息  
   
  WM_SETTEXT  
  An   application   sends   a   WM_SETTEXT   message   to   set   the   text   of   a   window.    
   
  WM_SETTEXT    
  wParam   =   0;                                           //   not   used;   must   be   zero    
  lParam   =   (LPARAM)(LPCTSTR)lpsz;   //   address   of   window-text   string    
     
  Parameters  
  lpsz    
  Value   of   lParam.   Pointer   to   a   null-terminated   string   that   is   the   window   text.    
  Return   Values  
  The   return   value   is   TRUE   if   the   text   is   set.   It   is   FALSE   (for   an   edit   control),   LB_ERRSPACE   (for   a   list   box),   or   CB_ERRSPACE   (for   a   combo   box)   if   insufficient   space   is   available   to   set   the   text   in   the   edit   control.   It   is   CB_ERR   if   this   message   is   sent   to   a   combo   box   without   an   edit   control.

  Dim   szStr   As   String  
  szStr   =   "AAAAAA"  
  SendMessage   txtMyText.hwnd,   WM_SETTEXT,   0,   ByVal   szStr  
   
  注意！必须用ByValTop
