{
    CMFCTabToolTipInfo* pInfo = (CMFCTabToolTipInfo*) lp;
    ASSERT (pInfo != NULL);

    if (pInfo)
    {
        ASSERT_VALID (pInfo->m_pTabWnd);
        if (!pInfo->m_pTabWnd->IsMDITab ())
        {
            return 0;
        }
        pInfo->m_strText.Format (_T("Tab #%d Custom Tooltip"), pInfo->m_nTabIndex + 1);
    }

    return 0;
