字符串里的\换成\\(CListBox*)GetDlgItem（IDC_LIST1)得先判断是否返回空。au_lname没写错？

CoInitialize(NULL); _ConnectionPtr pConn(__uuidof(Connection)); _RecordsetPtr pRst(__uuidof(Recordset)); pConn->ConnectionString="Data Source=SONY-VAIO\\SQLEXPRESS;Integrated Security=True";pConn->Open("","","",adConnectUnspecified); pRst = pConn->Execute("select Sno from Student",NULL,adCmdText); while(!pRst->rsEOF) {((CListBox*)GetDlgItem(IDC_LIST1))->AddString((_bstr_t)pRst->GetCollect("au_lname"));pRst->MoveNext();} pRst->Close(); pConn->Close(); pRst.Release(); pConn.Release(); CoUninitialize();

((_bstr_t)pRst->GetCollect("au_lname"))CString 封装一遍试试
