  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);
