  void CListDialogDlg::OnClickListCtrl(NMHDR* pNMHDR, LRESULT* pResult)
      {
         // TODO: Add your control notification handler code here
          NM_LISTVIEW* pNMListView = (NM_LISTVIEW*)pNMHDR;
         CString str;
         str.Format(_T(“Item index: %d,SubItem:%d”), pNMListView->iItem,

              pNMListView->iSubItem);
         MessageBox(str);
         *pResult = 0;
      }

  我改写后的,可以转为该路径下图像的代码

  void CRelCtrlDlg::OnNMClickListPhoto(NMHDR *pNMHDR, LRESULT *pResult)
  {
   // TODO: Add your control notification handler code here
   NM_LISTVIEW* pNMListView = (NM_LISTVIEW*)pNMHDR;
   CString str;
   str = m_ListCtrl.GetItemText( pNMListView->iItem, pNMListView->iSubItem ) ;
   str =  “\\”  + str;
   str = m_szPath + str;
   char *fileName = (LPSTR)(LPCTSTR)str;
   IplImage* img = cvLoadImage(fileName);

   *pResult = 0;
  }
