急！！（evc4.0＋ado3.1）create database 不成功 [复制链接]

程序段如下：
        hr=CLSIDFromProgID(g_szADOCE30ConnProgID,&tClsid);
        hr= CoCreateInstance(tClsid,NULL,CLSCTX_INPROC_SERVER|CLSCTX_LOCAL_SERVER,IID_Connection,(LPVOID*)&m_pADOCEConn);
        hr=m_pADOCEConn->put_Provider(TEXT("cedb"));
        hr=CLSIDFromProgID(g_szADOCE30RSProgID,&tClsid);
        hr= CoCreateInstance(tClsid,NULL,CLSCTX_INPROC_SERVER|CLSCTX_LOCAL_SERVER,IID_Recordset,(LPVOID*)&m_pADOCERS); //以上都已成功

        wcscpy(szSqlBuf,_T("CREATE DATABASE'\test.cdb'"));
        VariantInit(&varTSQL);
        VariantInit(&varEmpty);
        varTSQL.bstrVal = SysAllocString(szSqlBuf);
        varTSQL.vt = VT_BSTR;

        hr=m_pADOCERS->Open(varTSQL, varEmpty, MSADOCE::adOpenDynamic,MSADOCE::adLockOptimistic,MSADOCE::adCmdText);
        //此处create database失败

不知道哪里出错，忘指教！！！
