How do I change a Crystal Report's ODBC database connection at runtime?

Question

I have a report made with Crystal Reports 2008 that I need to deploy a production system which means that I need to be able to change the database connection at runtime. Th

Updating the ODBC within a crystal report file.

We are using ODBC with MSSQL, we couldn't find how to update the ODBC within the crystal files within a C sharp project.

With the example provided here we were able to find the way to update the ODBC within MSSQL, and it is as simple as this:

       Cursor.Current = Cursors.WaitCursor;

        CrystalDecisions.Windows.Forms.CrystalReportViewer CR_Viewer;
        CR_Viewer = new CrystalDecisions.Windows.Forms.CrystalReportViewer();
        this.Controls.Add(CR_Viewer);

        ConnectionInfo connInfo = new ConnectionInfo();
        connInfo.ServerName = "YOUR ODBC NAME"; 

        TableLogOnInfo tableLogOnInfo = new TableLogOnInfo();
        tableLogOnInfo.ConnectionInfo = connInfo;

         //THIS IS A CRYSTAL RPT FILE DIFINE AS A CLASS
        Facturation_Nord_Ouest.Reports.Facture_Français CrystalReportFr;


       CrystalReportFr = new Facturation_Nord_Ouest.Reports.Facture_Français();

            for (int i = 0; i < CrystalReportFr.Database.Tables.Count; i++)
            {
                CrystalReportFr.Database.Tables[i].ApplyLogOnInfo(tableLogOnInfo);
            }
            CR_Viewer.ReportSource = CrystalReportFr;

        CR_Viewer.ActiveViewIndex = 0;
        CR_Viewer.BorderStyle = System.Windows.Forms.BorderStyle.FixedSingle;
        CR_Viewer.Dock = System.Windows.Forms.DockStyle.Fill;
        CR_Viewer.Location = new System.Drawing.Point(0, 0);
        CR_Viewer.Size = new System.Drawing.Size(545, 379);
        CR_Viewer.TabIndex = 0;
        CR_Viewer.Name = "Invoice";
        CR_Viewer.Zoom(100);
        CR_Viewer.Show();

        Cursor.Current = Cursors.Default;

With this the ODBC in the crystal file is automaticaly updated.
