Hi!

I’d like to change the caption of my controlbars dynamically, as a response of a menucommand. SetWindowText works fine for all controlbars except for those in document-state. I haven’t found any method for setting __EBCT_DOCUMENT_CONTAINER_CAPTION, only for getting it (OnGetBarCaptionText()). I could work around the problem with the following code:

bool bVisible;
if (m_pwndMyBar->BarStateGet(&bVisible) == CExtDynamicControlBar::__EDBS_DOCUMENT) {
  m_pwndMyBar->BarStateSet(CExtDynamicControlBar::__EDBS_DOCKED, true);
  m_pwndMyBar->SetWindowText(strNewCaption);
  m_pwndMyBar->BarStateSet(CExtDynamicControlBar::__EDBS_DOCUMENT, bVisible);
}

, but this causes an ugly flickering. Isn’t there a better solution for this problem? Or maybe this is also solved in your new versions (we’re still using 2.43)?

Thank you for your help! Have a merry and restful holiday (as much as it is possible:))!

The caption text computing mechanism for the control bar now works absolutely like as in 2.43. So, please use the following code:

 
m_pwndMyBar->SetWindowText( strNewCaption );
if ( m_pwndMyBar->BarStateGet() == CExtDynamicControlBar::__EDBS_DOCUMENT )
{ 
    HWND hWnd = m_pwndMyBar->OnQueryChildHWND();
    ASSERT( hWnd != NULL && ::IsWindow( hWnd ) );
    hWnd = ::GetParent( hWnd );
    ASSERT( hWnd != NULL && ::IsWindow( hWnd ) );
    CWnd * pWnd = CWnd::FromHandlePermanent( hWnd );
    ASSERT_VALID( pWnd );
    CMDIChildWnd * pFrame =
        STATIC_DOWNCAST( CMDIChildWnd, pWnd );
    pFrame->SetTitle( strNewCaption );
}

Hi!

This does not work for me:( At the line "CMDIChildWnd * pFrame = STATIC_DOWNCAST( CMDIChildWnd, pWnd );" I get an assertion, because at that point pWnd points to my view, which is of CExtTabPageContainerWhidbeyWnd class that cannot be converted to CMDIChildWnd.
Which other class should I use to call SetTitle then?

Thank you: Chris

The solution we advised you works for MDI applications with the MDI tab window and dynamic resizable control bars. This approach cannot be used for SDI applications which use dynamic resizable control bars and the tab page container window as the main view window. Please use the following code instead:

m_pwndMyBar->SetWindowText( strNewCaption );
if ( m_pwndMyBar->BarStateGet() == CExtDynamicControlBar::__EDBS_DOCUMENT )
{ 
    HWND hWndBarChild = m_pwndMyBar->OnQueryChildHWND();
    ASSERT( hWndBarChild != NULL && ::IsWindow( hWndBarChild ) );
    HWND hWnd = ::GetParent( hWndBarChild );
    ASSERT( hWnd != NULL && ::IsWindow( hWnd ) );
    CWnd * pWnd = CWnd::FromHandlePermanent( hWnd );
    ASSERT_VALID( pWnd );
    CExtTabPageContainerWnd * pWndTPC =
        STATIC_DOWNCAST( CExtTabPageContainerWnd, pWnd );
    LONG nIndex = pWndTPC->PageFindByHWND( hWndBarChild );
    ASSERT( nIndex >= 0 );
    pWndTPC->PageTextSet( strNewCaption );
}
