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;

}
