Removing the close caption dynamically

Hi all,

I´m working with a MDI aplication and I have several (about 3 or 4) windows opened. the situation is if an indicated window is closed, another indicated windows cannot be closed anymore. I trying to remove its close caption but I haven´t had success. Can anyone tell me how to remove ( od disable) the close caption of a MDI child window dynamically?

Thank you in advance.

How did you "try to remove its close caption"? Didi you use GetSystemMenu ? Something like this:

Code:

---

        CMenu *pSysMenu = GetSystemMenu(FALSE);
        ASSERT(pSysMenu != NULL);
        VERIFY(pSysMenu->RemoveMenu(SC_CLOSE, MF_BYCOMMAND));        // or you could use CMenu::EnableMenuItem to disable it:
        // pSysMenu->EnableMenuItem(SC_CLOSE, MF_GRAYED | MF_BYCOMMAND);
        // ... and to enable it:
        //  pSysMenu->EnableMenuItem(SC_CLOSE, MF_ENABLED | MF_BYCOMMAND);
