Forums » Prof-UIS Tech Support » Crash in control bars with some are in auto-hide state Collapse All
Subject Author Date
Offer Har May 11, 2010 - 4:46 AM

Dear Support,


I have 2 control-bars - one is in docked in auto-hide to one edge of the main-frame, and the second is hidden.


I now what to show the hidden control-bar, so I show it, and I want it to be displayed next to the cursor, so I call FloatControlBar. The minute I call this function my application crashes, at this location:


 


bool CExtBarNcAreaButton::IsBarAutoHideMode(
    bool * p_bDisplayed, // = NULL
    bool * p_bActive // = NULL
    ) const
{
    ASSERT_VALID( this );
    if( p_bDisplayed != NULL )
        *p_bDisplayed = false;
    if( p_bActive != NULL )
        *p_bActive = false;
bool bAutohide = m_pBar->AutoHideModeGet();
    if( !bAutohide )
        return false;
    if( p_bDisplayed != NULL || p_bActive != NULL )
    {
        ASSERT_VALID( m_pBar->m_pDockBar );
        ASSERT_KINDOF( CExtDockBar, m_pBar->m_pDockBar );
...



And I see that m_pBar->m_pDockBar is of type CDockBar and not CExtDockBar


What is the problem? How to fix this? Is this a bug?


Below is the call-stack.


Thanks!


Ron.

Thank you for reporting this issue. Please update the source code for the following method:

bool CExtBarNcAreaButton::IsBarAutoHideMode(

Dear Support,


It did prevent the crash at the above location, but now it crashes in a different place:



void CFrameWnd::ShowControlBar(CControlBar* pBar, BOOL bShow, BOOL bDelay)
{
    ENSURE_VALID(pBar);
    CFrameWnd* pParentFrame = pBar->GetDockingFrame();
    ASSERT(pParentFrame->GetTopLevelParent() == GetTopLevelParent());
        // parent frame of bar must be related

    if (bDelay)
    {
        pBar->DelayShow(bShow);
        pParentFrame->DelayRecalcLayout();
    }
    else
    {
        pBar->SetWindowPos(NULL, 0, 0, 0, 0,
            SWP_NOZORDER|SWP_NOMOVE|SWP_NOSIZE|SWP_NOACTIVATE|
            (bShow ? SWP_SHOWWINDOW : SWP_HIDEWINDOW));
        // call DelayShow to clear any contradictory DelayShow
        pBar->DelayShow(bShow);
        if (bShow || !pBar->IsFloating())
            pParentFrame->RecalcLayout(FALSE);
    }

    // show or hide the floating frame as appropriate
    if (pBar->IsFloating())
    {
        int nVisCount = pBar->m_pDockBar != NULL ?
            pBar->m_pDockBar->GetDockedVisibleCount() : bShow ? 1 : 0;
        if (nVisCount == 1 && bShow)
        {
            pParentFrame->m_nShowDelay = -1;
            if (bDelay)
            {
                pParentFrame->m_nShowDelay = SW_SHOWNA;
                pParentFrame->RecalcLayout(FALSE);
            }
            else
                pParentFrame->ShowWindow(SW_SHOWNA);
        }
        else if (nVisCount == 0)
        {
            ASSERT(!bShow);  <<<<<< THIS IS WHERE IT ASSERTS
            pParentFrame->m_nShowDelay = -1;
            if (bDelay)
                pParentFrame->m_nShowDelay = SW_HIDE;
            else
                pParentFrame->ShowWindow(SW_HIDE);
        }
        else if (!bDelay)
        {
            pParentFrame->RecalcLayout(FALSE);
        }
    }
}

This happens only if I have a control-bar in the auto-hide mode, otherwise it does not asserts there.


Thanks,


Ron.
Technical Support May 25, 2010 - 1:42 AM

Please check the auto-hidden state first. I.e. do not invoke the CFrameWnd::ShowControlBar() API for the auto-hidden bars:

CExtControlBar * pBar = . . .
CMainFrame * pMainFrame = . . .
            if( pBar->AutoHideModeGet() )
                        pBar->AutoHideModeSet( . . . ); // this API can hide the auto-hidden bar
            else
                        pMainFrame->ShowControlBar( pBar, . . . );
