Question

I have an application (NOT MY Coding) which have a lot of crystal reports.
the problem I’m facing is that every time i open a crystal report it asks for login username and password.

after a little search i found that i have to set the connectioninfo for the report at run time and i found some solution but when i looked at the code of the application i didn’t find it as i was expecting.

the frmviewrpt (the form that has the crystal report viewer) have some thing like this:

RptProBalance rptProductBalance = new RptProBalance();
rptProductBalance.RecordSelectionFormula = getBalanceRptSelection();
rptProductBalance.Refresh();
allReportViewer.ReportSource = rptProductBalance; 

the RptProBalance() (the cs file that is extended from the RptProBalance.rpt file):

I have no clue where exactly I’m supposed to make the connection info and pass it to the report.

Answer 1

ConnectionInfo crconnectioninfo = new ConnectionInfo();
    ReportDocument cryrpt = new ReportDocument();
    TableLogOnInfos crtablelogoninfos = new TableLogOnInfos();
    TableLogOnInfo crtablelogoninfo = new TableLogOnInfo();

    Tables CrTables;

    crconnectioninfo.ServerName = "localhost";
    crconnectioninfo.DatabaseName = "dbclients";
    crconnectioninfo.UserID = "ssssssss";
    crconnectioninfo.Password = "xxxxxxx";  


  cryrpt.Load(Application.StartupPath + "\\rpts\\" + dealerInfo.ResourceName);

        CrTables = cryrpt.Database.Tables;

        foreach (CrystalDecisions.CrystalReports.Engine.Table CrTable in CrTables)
        {
            crtablelogoninfo = CrTable.LogOnInfo;
            crtablelogoninfo.ConnectionInfo = crconnectioninfo;
            CrTable.ApplyLogOnInfo(crtablelogoninfo);
        }


        cryrpt.RecordSelectionFormula = getCustInfoRptSelection();
        cryrpt.Refresh();

        allReportViewer.ReportSource = cryrpt;
