                crTable.ApplyLogOnInfo(crTableLogOnInfo);
            }
            doc.SetDataSource(dataSet.Tables[0]);
            conn.Close();
            sqlCon = "";
            conn = new SqlConnection(sqlCon);

            adpt = new SqlDataAdapter(cmd);
            DataSet ds = new DataSet();
            adpt.Fill(ds, "Customers1");

            doc.Subreports["CrystalReport2.rpt"].SetDataSource(ds.Tables[0]);
            CrystalReportViewer1.ReportSource = doc;
        }
