Viewer shows data multiple times

Question

Hello everybody,
after the answer i got from the thread  , i edited my code.
But i got the problem, that i received the data multiple times.
The information are still the same like written in the other thread.
I work on three tables: Adressen, Auftragseingang and Arbeitspläne.
In the detail section of the Report i want to show the data of the table Arbeitspläne and in the header section i want to show data of the tables Adressen and Auftragseingang.
This is the code i wrote:
using System;
using System.Collections.Generic;
using System.ComponentModel;
using System.Data;
using System.Drawing;
using System.Linq;
using System.Text;
using System.Windows.Forms;
using CrystalDecisions.Shared;
using System.Data.SqlClient;
using CrystalDecisions.CrystalReports.Engine;
using CrystalDecisions.Windows.Forms;
namespace CrystalReportsApplication1
    public partial class Form1 : Form
        public Form1()
            InitializeComponent();
        private void button1_Click(object sender, EventArgs e)
            SqlConnection connection = new SqlConnection("Data Source=SRVVMSQL001.de.eurodok.org;Initial Catalog=PROPLANOrg;Integrated Security=True");
            SqlCommand command;
            DataSet ds;
            try
                command = new SqlCommand();
                command.Connection = connection;
                command.CommandType = CommandType.Text;
                command.CommandText = "SELECT * FROM Auftragseingang, Arbeitspläne, Adressen WHERE Auftragseingang.[Auftrag-Nr] = 113 AND Auftragseingang.Kundennummer = Adressen.Kundennummer AND Auftragseingang.[Zeichnung-Nr] = Arbeitspläne.[Zeichnung-Nr]";
                connection.Open();
                SqlDataAdapter dataAdapter = new SqlDataAdapter(command);
                ds = new DataSet("ABC");
                dataAdapter.Fill(ds, "Auftragseingang");
                dataAdapter.Fill(ds, "Adressen");
                dataAdapter.Fill(ds, "Arbeitspläne");
                CrystalReport1 cryRpt = new CrystalReport1();
                cryRpt.SetDataSource(ds);
                crystalReportViewer1.ReportSource = cryRpt;
                crystalReportViewer1.Refresh();
                SqlDataReader dataReader;
                int i = 0;
                dataReader = command.ExecuteReader();
                while (dataReader.Read())
                    i++;//hier werden die ausgelesenen Datensätze gezählt
                MessageBox.Show("Message: Anzahl Datensätze: " + i);//hier kommt der richtige wert raus, was die Anzahl der Datensätze angeht||jedoch wird im Report ein vielfaches angezeigt
            catch (Exception ex)
                MessageBox.Show("Message:
" + ex.Message + "
" +
                                 "Data:
" + ex.Data + "
" +
                                 "InnerException:
" + ex.InnerException + "
" +
                                 "StackTrace:
" + ex.StackTrace + "
" +
                                 "TargetSites:
" + ex.TargetSite,
                                 "[" + ex.Source + "] FEHLER - Programm wird beendet.", MessageBoxButtons.OK, MessageBoxIcon.Error);
            finally
                connection.Close();

More than likely that is a table linking or report design issue. In either case, the best thing to do will be to post the query to the [SAP Crystal Reports Design|SAP Crystal Reports, version for Visual Studio; forum. When you post to that forum, a link to a screenshot will also be helpful.
Umm, also you mention that the answer on the other tread (Report shows no data in the Viewer )  was correct and helped you to resolve the issue of displaying the report in the viewer. Yet all you appear to have done is closed the thread without awarding any points(?).
