How to add description in dynamically created CMFCToolbar's ToolTip?

The CMFCToolbar Inherits the function EnableToolTip which does not help the developer if he is creating the toolbar dynamically and not adding the Description and title in resource. I made an extension for CMFCToolBar and wrote a function :

BOOL CMFCToolBarEx::OnNeedTipText(UINT /*id*/, NMHDR* pNMH, LRESULT* /*pResult*/)
{
    TOOLTIPTEXT *pTTT = (TOOLTIPTEXT *)pNMH;
   // UINT nID = static_cast<int>(pNMH->idFrom);
    CString strTip = _T("");

    CPoint point;
    ::GetCursorPos(&point);
    ScreenToClient(&point);
    INT_PTR nHit = ((CMFCToolBar*)this)->HitTest(point);

    if(nHit == -1)
        return FALSE;

    CMFCToolBarButton* pButton = GetButton((int)nHit);
    strTip = pButton->m_strText;
    _tcscpy(pTTT->lpszText , strTip.GetBuffer(0));

    return TRUE;
}

to show tooltip in cmfctoolbar button.

The cmfctoolbar button takes no parameter and has no function to set description. The constructor takes parameter like :

pToolBarButton = new CMFCToolBarButton(nId, nIconIndex, lpszText);

If I set the parameter lpszText with title only the tooltip appears like this

I need to add description to this toolbar and view it like this if anyone can suggest a better way to do it

Anyone looking for answer. Here you go just add

CTooltipManager::SetTooltipText((TOOLINFO*) pTTT, m_pToolTip, AFX_TOOLTIP_TYPE_TOOLBAR, strTip, strDescr); 

to your overridden onneedtiptext function.
