Is it possible to add CMFCToolBar to a dialog?

I just tryed the standard way for adding CToolbar to a dialog on the new CMFCToolBar. But it doesn't work. Before I dip into the new implementation, I want to know if it actually possible?

If you only have to deal with dialog-only commands the trick is to set SetRouteCommandsViaFrame to FALSE. Then the owner (usually the dialog) will be used for commands instead of the main frame.

The OnInitDialog above does work well except in cases where the command is a dialog-only command.

If there is no application or main-frame handler the button disables itself and the handler is not called. Note that the above code routes correctly because ID_APP_ABOUT and ID_APP_EXIT already have CWinAppEx handlers.

A workaround that does not involve overriding OnCmdMsg is to add a handler at the application or main-frame level. The toolbar then stays active and will correctly find its way to the proper dialog handler. Adding a simple void handler to CMainFrame does the trick (sample code below). The void handler is not called.

BOOL CMyDlg::OnInitDialog()                    
{                    
    ...  
    m_ToolBar.InsertButton( CMFCToolBarButton( **ID_DLG_COMMAND**, -1, _T("DlgCommand") ) ); 
    ...     
}    

//CMainFrame
BEGIN_MESSAGE_MAP(CMainFrame, CMDIFrameWndEx)
...
    ON_COMMAND(**ID_DLG_COMMAND**, VoidHandler)
END_MESSAGE_MAP()

void CMainFrame::VoidHandler()
{
    assert(0);
}

I'm not sure what you mean by "the standard way", but you can certainly do it programatically:

// In MyDlg.h
class CMyDlg : public CDialog
{
...
    CMFCToolBar m_ToolBar;
...
};

// In MyDlg.cpp
BOOL CMyDlg::OnInitDialog()
{
...
    if( m_ToolBar.Create( this, AFX_DEFAULT_TOOLBAR_STYLE, 100 ) )
    {
        m_ToolBar.SetPaneStyle( m_ToolBar.GetPaneStyle() 
            & ~(CBRS_GRIPPER | CBRS_SIZE_DYNAMIC | CBRS_BORDER_ANY) );

        m_ToolBar.InsertButton( CMFCToolBarButton( ID_APP_ABOUT, -1, _T("About") ) );
        m_ToolBar.InsertButton( CMFCToolBarButton( ID_APP_EXIT, -1, _T("Exit") ) );

        CSize   sizeToolBar = m_ToolBar.CalcFixedLayout( FALSE, TRUE );
        m_ToolBar.SetWindowPos( NULL, 0, 0, sizeToolBar.cx, sizeToolBar.cy,
            SWP_NOACTIVATE | SWP_NOZORDER );
    }
...
}
