      这是个很简单又是编程中经常要遇到的问题.                                    
     第一问,向窗口发送 WM_CLOSE消息,调用 CWnd::OnClose成员函数.允许对用户提      
示                                                                               
    是否保存修改过的数据.                                                        
     Example: AfxGetMainWindow()->SendMessage(WM_CLOSE);                         
                                                                                 
    还可以创建一个自定义的函数 Terminate Window                                  
      void Terminate Window(LPCSTR pCaption)                                     
      {                                                                          
          CWnd *pWnd=Cwnd::FindWindow(NULL,pCaption);                            
               if (pWnd)                                                         
                  pWnd ->SendMessage(WM_CLOSE);                                  
      }                                                                          
                                                                                 
   说明: FindWindow函数不是提倡的做法，因为它无法处理标题栏自动改变，比如        
   我们要检测 Notepad是不是已运行而事先不知道Notepad的标题栏,这时                
FindWindow就                                                                     
   无能为力了，可以通过枚举 windows任务列表的办法来实现。 在 机械出版社          
   "Windows 95 API开发人员指南"一书有比较详细的介绍,这里就不再多说乐。           
                                                                                 
  第二问,Use ExitWindowsEx Function函数控制系统是重新引导，还是重启              
windows.
