CToolTip and CListCtrl

I am implementing tooltips for a CListCCtrl derived class

BOOL CMyListCtrl::OnToolTipText( UINT id, NMHDR * pNMHDR, LRESULT * pResult )
     CString strTipText;
     UINT nID = pNMHDR->idFrom;

     if( nID == 0 )// Notification in NT from automatically
       return FALSE;        // created tooltip

  I have done everything I think but nID is always false

  I do handle OnToolHitTest and set the id of the row by hittesting. I do call enable tootips in PreSubClassWindow.

 Anyone know why nID would always be Zero?
