            //SqlConnection conn = new SqlConnection(strConnection);
            //SqlCommand com = new SqlCommand();
            ////com.Connection = strConnection;
            //com.CommandText = "SELECT C.Cid, S.Cid, S.SubCid, S.CName, C.CommName, C.CommTime, C.CommSubject, C.CommBody FROM SubComm AS S LEFT JOIN Comments AS C ON (C.Cid=S.Cid)";
