Remove close button from system menu

I am currently using Office2007 theme with

CXTPDialogBase<CXTResizeDialog> and CXTPOffice2007FrameHook

I am trying to get rid of the close button in the system menu which is usually done like this; however, this does not seem to work. Any suggestions?

    CMenu* pSysMenu = GetSystemMenu(FALSE);
    if (pSysMenu != NULL)
        pSysMenu->RemoveMenu(SC_CLOSE,MF_BYCOMMAND);

Hi,

I don't want to remove the whole system menu. I would just like to disable or remove the close button.

Hi,

The above solution functions as long as I do not have "EnableOffice2007Frame(pCommandBars)" in my code. I would like to maintain this frame for my look and feel. Here is a little more code to debug the problem.

#define CDialogDlgBase CXTPDialogBase<CXTResizeDialog>

BOOL CMyApp::OnInitDialog()
{
    CDialogDlgBase::OnInitDialog();

    // Init the menus

    VERIFY(InitCommandBars());

    CXTPCommandBars* pCommandBars = GetCommandBars();

    LoadCommandBars(_T("CommandBars"));

    // Set the Office 2007 theme

    CXTPPaintManager::SetCustomTheme(new    CXTPOffice2007Theme());
    EnableOffice2007Frame(pCommandBars);
    pCommandBars->RedrawCommandBars();

    CMenu* pSysMenu = GetSystemMenu(FALSE);
    if (pSysMenu != NULL)
        pSysMenu->EnableMenuItem(SC_CLOSE, MF_DISABLED);

     return TRUE;
}
