Question

I'm trying to display some report with some subreports inside it, but every it shows the report it throws some dialog box asking for database connection. I'm using this code:

private void frmReporte_Load(object sender, System.EventArgs e)
    {
        Clave = ConfigurationSettings.AppSettings["Password"].ToString();
        NombreBD = ConfigurationSettings.AppSettings["CatalogBD"].ToString();
        NombreServidor = ConfigurationSettings.AppSettings["Servidor"].ToString(); ;
        UsuarioBD = ConfigurationSettings.AppSettings["UserID"].ToString();
        this.crtReportes.ReportSource = this.prepareReport();
    }
    public void imprimirReporte()
    {
        ReportDocument rpt = new ReportDocument();
        rpt.Load(mvarRutaReporte);
        rpt.SetDataSource(clsReportes.dsReporte);
        rpt.PrintToPrinter(1, false, 1, 1);
    }
    private ReportDocument prepareReport()
    {
        Sections crSections;
        ReportDocument crReportDocument, crSubreportDocument;
        SubreportObject crSubreportObject;
        ReportObjects crReportObjects;
        ConnectionInfo crConnectionInfo;
        Database crDatabase;
        Tables crTables;
        TableLogOnInfo crTableLogOnInfo;
        crReportDocument = new ReportDocument();
        crReportDocument.Load(RutaReporte);
        crReportDocument.SetDataSource(clsReportes.dsReporte.Tables[0]);
        crDatabase = crReportDocument.Database;
        crTables = crDatabase.Tables;
        crConnectionInfo = new ConnectionInfo();
        crConnectionInfo.ServerName = NombreServidor ;
        crConnectionInfo.DatabaseName = NombreBD;
        crConnectionInfo.UserID = UsuarioBD;
        crConnectionInfo.Password = Clave;
        foreach (CrystalDecisions.CrystalReports.Engine.Table aTable in crTables)
        {
            crTableLogOnInfo = aTable.LogOnInfo;
            crTableLogOnInfo.ConnectionInfo = crConnectionInfo;
            aTable.ApplyLogOnInfo(crTableLogOnInfo);
        }
        // Para los reportes que poseen subreportes 
        // pongo el objeto seccion del la seccion actual del reporte 
        crSections = crReportDocument.ReportDefinition.Sections;
        // busco en todas las secciones el objeto reporte
        foreach (Section crSection in crSections)
        {
            crReportObjects = crSection.ReportObjects;
            //busco en todos los reportes por subreportes
            foreach (ReportObject crReportObject in crReportObjects)
            {
                if (crReportObject.Kind == ReportObjectKind.SubreportObject)
                {
                    crSubreportObject = (SubreportObject)crReportObject;
                    //abro el subreporte y me logeo con los datos del reporte general
                    crSubreportDocument = crSubreportObject.OpenSubreport(crSubreportObject.SubreportName);
                    crDatabase = crSubreportDocument.Database;
                    crTables = crDatabase.Tables;
                    foreach (CrystalDecisions.CrystalReports.Engine.Table aTable in crTables)
                    {
                        crTableLogOnInfo = aTable.LogOnInfo;
                        crTableLogOnInfo.ConnectionInfo = crConnectionInfo;
                        aTable.ApplyLogOnInfo(crTableLogOnInfo);
                    }
                }
            }
        }
        return crReportDocument;
    }

Answer 1

Hi,

In crystal u can specify whether to prompt for db login @ d time of report generation in Crystal Management Console (CMC) @ each report level. Login to CMC, open ur report > Process > Database. At the bottom of the page u can specify "Prompt the user for database logon", "Use SSO context for database logon" or "Use same database logon as when report is run". Select the third option for using the credentials stored in the server.

Regards ...

You can just write report.SetDatabaseLogon("username", "pwd", @"server", "database"); give the login information then the database logon box will not appear when you will run the code. Ashish S..
