   How do I 'attach' a menu to a window's creation/destruction? 
 ----------------------------------------------------------- 
 {Note the original question talked about dialogs, but you can interpolate 
 this 
 code to any kind of window that you want to have change the menu.} 
  
 One of the ways to do this is as follows** 
  
 1.  Declare a variable CMenu pNewMenu in one of the dialog class. 
  
 2.  Handle the WM_INITDIALOG and WM_CLOSE messages in the 
 dialog class as follows. 
  
 BOOL CMydlg::OnInitDialog() 
  
 { 
  
         CDialog::OnInitDialog(); 
  
         // Load the IDR_MYFRAME menu 
  
         pNewMenu = new CMenu; 
  
         pNewMenu->LoadMenu(IDR_MYFRAME); 
  
         // Set the mainframe menu to mainframe. 
  
         ((CMainFrame *)AfxGetMainWnd())->SetMenu(pNewMenu); 
  
         return TRUE; 
  
 } 
 And 
  
 void CMydlg::OnClose() 
  
 { 
  
         // Detach the previous HMenu handle from the object. 
  
         pNewMenu->Detach(); 
  
         pNewMenu->LoadMenu(IDR_MAINFRAME); 
  
         // Restore the mainframe menu. 
  
         ((CMainFrame *)AfxGetMainWnd())->SetMenu(pNewMenu); 
  
         CDialog::OnClose(); 
  
 } 
  
 4.   If there are other methods of closing the dialog (example- By clicking 
 a 
 button in the Dialog), then The code given above in OnClose handler, must 
 be 
 put in the button click handler.
