You can disable a menu item via following method:

CMenu* pMenu = GetMenu();

However, I recommend you use the ON_UPDATE_COMMAND_UI MFC macro to do this

To use the ON_UPDATE_COMMAND_UI MFC macro, select the view in ClassWizard, select the menu item (ID_FILE_NEW or whatever), and create a handle for ON_UPDATE_COMMAND_UI.

Here's example code for your ON_UPDATE_COMMAND_UI function:

void CMainFrame::OnUpdateCommand...(CCmdUI* pCmdUI)
     pCmdUI->Enable(bEnableThisMenuItem );    

In above example function, bEnableThisMenuItem is a member BOOL variable you create to enable or disable your menu item.

Hi either use the OnUpdate or Modify Menu

void CMainFrame::OnUpdateFileTest(CCmdUI* pCmdUI)

      //ModifyMenu(hMenu, SC_CLOSE, MF_BYCOMMAND|MF_GRAYED, SC_CLOSE, "Close")
