Add tooltip to a child window

I want to add tooltip to an ocx control placed on a dialog child window. I also have for the ocx mouse move event.
I used:

EnableToolTips(TRUE);
...
ON_NOTIFY_EX( TTN_NEEDTEXT, 0, OnToolTipNotify)
...
BOOL CTopologyDlg::OnToolTipNotify( UINT id, NMHDR * pNMHDR, LRESULT * pResult )
{
TOOLTIPTEXT *pTTT = (TOOLTIPTEXT *)pNMHDR;
UINT nID =pNMHDR->idFrom;
if (pTTT->uFlags & TTF_IDISHWND)
{
// idFrom is actually the HWND of the tool
nID = ::GetDlgCtrlID((HWND)nID);
if(nID)
{
pTTT->lpszText = MAKEINTRESOURCE(nID);
pTTT->hinst = AfxGetResourceHandle();
return(TRUE);
}
}
return(TRUE);
}

What else do I need ?

Thanks.

Do you need one tooltip for the Ocx item in a dialog or you need different tooltips in the Ocx item area? Which problems do you have?

PS:
nID = ::GetDlgCtrlID((HWND)nID);
Hurrah, Microsoft programming style!! :(

Do I have to use CToolTipCtrl ?
I see samples without the control

>I don't see the toolbar.
Do you want the toolbar on the dialog?

Here is the way for tooltip control:

class CTooltipControl: public CStatic
{
...
CToolTipCtrl m_ToolTip;
};

void CTooltipControl::PreSubclassWindow()
{
..
// Create the tooltip
CRect rect;
GetClientRect(rect);
m_ToolTip.Create(this);
m_ToolTip.AddTool(this, "My Tooltip", rect, TOOLTIP_ID);

CStatic::PreSubclassWindow();
}

BOOL CTooltipControl::PreTranslateMessage(MSG* pMsg)
{
m_ToolTip.RelayEvent(pMsg);
return CStatic::PreTranslateMessage(pMsg);
}
