I am trying to add/remove toolbars (CExtToolControlBar) at runtime. I am adding them ok however when I remove them , the docking site where the toolbar was before being removed doesnt shrink back to its original state - Leaving a redundant area which any remaining toolbars cannot dock into.

I am using the following code to remove a toolbar:

RemoveControlBar( &m_ToolBarArray[i] );
m_ToolBarArray[i].m_pDockSite        =    NULL;
m_ToolBarArray[i].m_pDockBar        =    NULL;
    m_ToolBarArray[i].DestroyWindow();
    CExtDockBar::_OptimizeCircles( this );
RecalcLayout();

(note: m_ToolBarArray is of type : CExtToolControlBar m_ToolBarArray[MAX_TOOLBARS]; )

Do I need to be removing them a different way?

Here is the function for killing any CExtControlBar window:

#include "../Src/ExtDockBar.h"
#include "../Src/ExtControlBarTabbedFeatures.h"

void KillBar(
    CExtControlBar * pBar,
    bool bForceNoOptimizeMode = false
    )
{
    ASSERT_VALID( pBar );
    ASSERT_VALID( pBar->m_pDockBar );
    ASSERT_VALID( pBar->m_pDockSite );
CFrameWnd * pDockSite = pBar->m_pDockSite;
    ASSERT( pDockSite->GetSafeHwnd() != NULL );
CMiniDockFrameWnd * pMiniFrame = NULL;
    if( pBar->IsFloating() )
    {
        pMiniFrame = 
            DYNAMIC_DOWNCAST(
                CMiniDockFrameWnd,
                pBar->GetDockingFrame()
                );
        ASSERT_VALID( pMiniFrame );
    } // if( pBar->IsFloating() )
    else
    {
        ASSERT( ! pBar->m_pDockBar->m_bFloating );
#if (!defined __EXT_MFC_NO_TAB_CONTROLBARS)
        if( pBar->AutoHideModeGet() )
        {
            ASSERT_KINDOF( CExtDockBar, pBar->m_pDockBar );
            CExtDynAutoHideArea * pWndAutoHideArea =
                ((CExtDockBar*)pBar->m_pDockBar)->_GetAutoHideArea();
            ASSERT_VALID( pWndAutoHideArea );
            CExtDynAutoHideSlider * pWndSlider =
                pWndAutoHideArea->GetAutoHideSlider();
            ASSERT_VALID( pWndSlider );
            if( (pWndSlider->GetStyle()&WS_VISIBLE) != 0 )
                pWndSlider->SendMessage( WM_CANCELMODE );
            pWndAutoHideArea->RemoveControlBar( pBar, true );
        } // if( pBar->AutoHideModeGet() )
#endif // (!defined __EXT_MFC_NO_TAB_CONTROLBARS)
        if( pBar->m_pDockBar->IsKindOf(RUNTIME_CLASS(CExtDockBar)) )
        {
#if (!defined __EXT_MFC_NO_TAB_CONTROLBARS)
            if( pBar->m_pDockBar->IsKindOf(RUNTIME_CLASS(CExtDockDynTabBar)) )
            {
                CExtDynTabControlBar * pTabbedBar =
                    STATIC_DOWNCAST(
                        CExtDynTabControlBar,
                        pBar->m_pDockBar->GetParent()
                        );
                LONG nIdx = pTabbedBar->FindControlBar( pBar );
                if( nIdx >= 0 )
                {
                    LONG nSel = pTabbedBar->GetSwitcherSelection();
                    if( nIdx != nSel )
                        pTabbedBar->SetSwitcherSelection( nIdx );
                    pTabbedBar->RemoveSelFromSwitcher();
                } // if( nIdx >= 0 )
            } // if( pBar->m_pDockBar->IsKindOf(RUNTIME_CLASS(CExtDockDynTabBar)) )
#endif // (!defined __EXT_MFC_NO_TAB_CONTROLBARS)
            VERIFY(
                ((CExtDockBar *)pBar->m_pDockBar)->
                    RemoveControlBar( pBar, -1, 0, false )
                );
        }
        else
        {
            VERIFY( pBar->m_pDockBar->RemoveControlBar(pBar) );
        }
    } // else from if( pBar->IsFloating() )
    pDockSite->RemoveControlBar( pBar );
    pBar->m_pDockSite = NULL;
    pBar->m_pDockBar = NULL;
    if( pMiniFrame != NULL )
        pMiniFrame->DestroyWindow();
    else
        pBar->DestroyWindow();
    if( ! bForceNoOptimizeMode )
        CExtDockBar::_OptimizeCircles( pDockSite );
}

Thank You!
