To assign pointer

  TC_ITEM TCI;
  TCI.mask = TCIF_PARAM;
  CMyPoint *pPt = new CMYPoint;
  TCI.lParam = (LPARAM)pPt;
  VERIFY(m_TabCtrl.InsertItem(0, &TCI) != -1);

To retreive pointer

  TC_ITEM TCI;
  TCI.mask = TCIF_PARAM;
  m_TabCtrl.GetItem(nTab, &TCI);
  CMyPoint *pPt = (CMyPoint *)TCI.lParam;
ASSERT_KINDOF(CMyPoint, pPt);
