 SqlParameter[] parms ={
            db.MakeInParam("@name",SqlDbType.VarChar,50,name),
            db.MakeInParam("@pass",SqlDbType.VarChar,50,pass),
            };

            StringBuilder sbf = new StringBuilder();
            sbf.Append(" select datediff(day,(select datetime from UserInfo where ID=1),getdate()) as day from UserInfo ");
            sbf.Append(" where name=@name");
            sbf.Append(" and pass=@pass");
         
            DataSet ds= db.RunProcReturn(sbf, parms,"User");
            int i =Int32.Parse( ds.Tables[0].Rows[0]["day"].ToString())  ;
            if (i > 0)
            {
                return true;
