Question

I’m developing a local app with friends and we’re using svn, but we have crystal reports, but it saves the last server used by one of my friends when doing the commit. I tried changing the server programatically using this piece of code, but it didn’t work :S

*UPDATE: it seems that the .rpt keeps a history of the server names, and somehow doesn’t seem to clear the list, so my friends computer “\sqlexpress” is still there, and I can’t seem to clear it :S”

   string nombre = WindowsIdentity.GetCurrent().Name.ToString().Split('\\')[1];
    ReportDocument cryRpt = new ReportDocument();
    TableLogOnInfos crtableLogoninfos = new TableLogOnInfos();
    TableLogOnInfo crtableLogoninfo = new TableLogOnInfo();
    ConnectionInfo crConnectionInfo = new ConnectionInfo();
    Tables CrTables ;            
    //cryRpt.SetDatabaseLogon(string.Empty,string.Empty, nombre + "\\sqlexpress","trupp");
    cryRpt.Load(FinalPath);
    crConnectionInfo.ServerName = nombre + "\\sqlexpress";
    crConnectionInfo.IntegratedSecurity = true;
    crConnectionInfo.UserID = string.Empty;
    crConnectionInfo.Password = string.Empty;
    crConnectionInfo.DatabaseName = "trupp";
    CrTables = cryRpt.Database.Tables;
    foreach (CrystalDecisions.CrystalReports.Engine.Table CrTable in CrTables)
    {
        crtableLogoninfo = CrTable.LogOnInfo;
        crtableLogoninfo.ConnectionInfo = crConnectionInfo;
        CrTable.ApplyLogOnInfo(crtableLogoninfo);
    }
    crystalReportViewer1.ReportSource = cryRpt;
    crystalReportViewer1.Refresh();

You need to make a call to clear the existing connections from the report before setting the new ones.

cryRpt.Load(FinalPath);
// After loading report clear all datasourceconnections
cryRpt.DataSourceConnections.Clear();
// Now you can set new datasourceconnections
crConnectionInfo.ServerName = nombre + "\\sqlexpress";

Sometimes Crystal Reports can be a pain so if for some reason the above doesn’t work you can always just set the server name on the existing connection embedded in the report.

cryRpt.DataSourceConnections[0].SetConnection(nombre + "\\sqlexpress", "trupp", true);
