I have some toolbars with comboboxes, but the controls are disabled and not changable.

See here a picture

What is wrong?

if(!m_wndServerListBar.Create(_T( "Resizable bar name" ),
        this,
        IDR_SERVERLIST
        )|| !m_wndServerListBar.LoadToolBar(IDR_SERVERLIST)
    )
    {
        TRACE0("Failed to create ServerListBar\n");
        return -1;
    }

    if( !m_ServerListComboBox.Create(
        WS_CHILD | WS_VISIBLE |CBS_HASSTRINGS | CBS_DROPDOWN,
        CRect( 0, 0, 400, 480 ),
        &m_wndServerListBar,
        ID_SERVERLIST_COMBO
        ) || !m_wndServerListBar.SetButtonCtrl(
        m_wndServerListBar.CommandToIndex(
        m_ServerListComboBox.GetDlgCtrlID() ),
        &m_ServerListComboBox
        )
        )
    {
        TRACE0("Failed to create help search combobox\n" );
        return -1;
    }

m_wndServerListBar.EnableDocking(CBRS_ALIGN_ANY);

    if( !CExtControlBar::FrameEnableDocking(this) )
    {
        ASSERT( FALSE );
        return -1;
    }

DockControlBar(&m_wndServerListBar);

RecalcLayout();

The CExtToolControlBar window manages a set of its buttons using MFC’s command update mechanism. The enabled/disabled state of a command button (which looks and acts like an ordinary push button) in a toolbar, is updated absolutely like the enabled/disabled state of the toolbar button with a combo box window attached.

So, if you create a combo box window in a toolbar and attach it to the button specified by the ID_SERVERLIST_COMBO command identifier, then the enabled/disabled state of this button is updated absolutely like if this button were an ordinary push button in the toolbar. This button is enabled if the command handler for ID_SERVERLIST_COMBO is available in the main frame window or the command updating handler is added and it enables the command by invoking the pCmdUI->Enable() code. So, simply add the command handler method for the ID_SERVERLIST_COMBO command and leave this method body empty.
