   My app sometimes need to disable/enable the (X) button (the top-right button on screen), it worked correctly with the following code:

    HMENU hMenu = ::GetSystemMenu(m_hWnd,FALSE);
    if (hMenu)
        EnableMenuItem(hMenu,SC_CLOSE,bEnable ? MF_ENABLED : MF_GRAYED);

  But when I apply skin for this form, the close button is not enable or disable as I expected (always enable or disable).

 Plz help me,

 Thanks a lot!

	I have not used skins but I do use the command ribbon with one of the word styles. For me to disable the close icon I first have to find the control and change the update flag. I do this: if (CXTPControl* pCloseControl = pRibbonBar->GetControls()->FindControl(XTP_ID_MENUBAR_CLOSE)) { pCloseControl->SetFlags( pCloseControl->GetFlags() & ~xtpFlagManualUpdate ); } Then I went into my OnCmdMsg handler and looked for the control with an id of XTP_ID_MENUBAR_CLOSE. Then simply set the enabled flag of the update UI object passed in. I do the same thing you do to disable the original windows SC_CLOSE object and I get the menu item and examine its enabled/grayed state to base my setting of the flag. So you are almost there.

	First, thanks rdhd, but "Then I went into my OnCmdMsg handler and looked for the control with an id of XTP_ID_MENUBAR_CLOSE. Then simply set the enabled flag of the update UI object passed in." I don't know how to do this, can you show me how to do this task? Thanks a lot!
