I implemented the method OnNcAreaButtonsReinitialize in my CExtControlBar derived class and I got rid of the ’x’ in the title bar.

My application has several control bars, none of which individually has the ’x’ any more. However, when I combine several control bars into one tabbed control bar, the ’x’ becomes visible again, and the control bars can be closed. This poses a big issue, as my app doesn’t provide a way to reopen the control bars, other than by deleting the keys in the registry. How do I ensure that the ’x’ never appears in the title bar, even in this case of tabbed control bars?

Thanks,

Adrian

The tabbed control bar container is a newly/dynamically created resizable control bar which keeps both docked CExtControlBar windows and the CExtTabWnd tab control. This tabbed container is implemented as the CExtDynTabControlBar class. To hide the Close or X button, create a CExtDynTabControlBar-derived class and override the OnNcAreaButtonsReinitialize() virtual method similar to as you already did this in your CExtControlBar-derived class.

To use your tabbed control bar container in Prof-UIS, add a message handler for the CExtControlBar::g_nMsgCreateTabbedBar registered windows message:

// declaration in the header file
afx_msg LRESULT OnMsgCreateTabbedBar( 
   WPARAM wParam, 
   LPARAM lParam 
);
 
// message map entry
ON_REGISTERED_MESSAGE(
    CExtControlBar::g_nMsgCreateTabbedBar,
    OnMsgCreateTabbedBar
    )
 
// implementation
LRESULT CMainFrame::OnMsgCreateTabbedBar(
    WPARAM wParam, LPARAM lParam )
{
CExtDynTabControlBar ** ppTabbedBar =
        (CExtDynTabControlBar **)wParam;
    ASSERT( ppTabbedBar != NULL );
    (*ppTabbedBar) =
        new C_YOUR_DynTabControlBar;
    return 0;
}
