DatabaseLogOnList - Use the LogOnInfos property to specify logon infos

Question

Hi,
I use CRYSTAL REPORT 2008 to develop reports and view these reports using crystalreportsviewers in web application on dot net framework.
when I run this application the report displayed the messege "DatabaseLogOnList - Use the LogOnInfos property to specify logon infos".
could you tell me why and soluction please?
The code is:
ParameterField parametro;
ParameterDiscreteValue parametroVal;
DataTable dt;
ReportDocument crReportDocument;
FormulaFieldDefinition crFormulaDefinition;
string db = System.Configuration.ConfigurationManager.AppSettings["Database"].ToString();
string user = System.Configuration.ConfigurationManager.AppSettings["Username"].ToString();
string pwd = System.Configuration.ConfigurationManager.AppSettings["Password"].ToString();
string server = System.Configuration.ConfigurationManager.AppSettings["Server"].ToString();
string RPTtemplatePath;
//--inizializzazione report--
crReportDocument = new ReportDocument();
crReportDocument.Load(RPTtemplatePath);
//--inizializzazione report--
ConnectionInfo crConnInfo = new ConnectionInfo();
crConnInfo.DatabaseName = db;
crConnInfo.UserID = user;
crConnInfo.Password = pwd;
crConnInfo.ServerName = server;
crConnInfo.IntegratedSecurity = false;                                               
//autentico il mio report principale
SetDBLogonForReport(crConnInfo, crReportDocument);
//autentico tutti i sottoreport richiamati dal report principale
SetDBLogonForSubreports(crConnInfo, crReportDocument);
//--istanza ODS per report (DATATABLE)--
dt = new DataTable();
it.cdlan.gestionale.bll.objectManager.report.Report_Mgr MGR = new it.cdlan.gestionale.bll.objectManager.report.Report_Mgr();
dt = MGR.GetDTInterventiFatturazione(idAnagrafica, idServizio, dataFatturazione);
crReportDocument.SetDataSource(dt);
//--istanza ODS per report (DATATABLE)--
//--parametri per report--
parametro = new ParameterField();
parametroVal = new ParameterDiscreteValue();
parametro.Name = "idAnagrafica";
parametroVal.Value = idAnagrafica;
crReportDocument.SetParameterValue("idAnagrafica", parametroVal.Value);
parametro = new ParameterField();
parametroVal = new ParameterDiscreteValue();
parametro.Name = "idServizio";
parametroVal.Value = idServizio;
crReportDocument.SetParameterValue("idServizio", parametroVal.Value);
parametro = new ParameterField();
parametroVal = new ParameterDiscreteValue();
parametro.Name = "dataFatturazione";
parametroVal.Value = dataFatturazione;
crReportDocument.SetParameterValue("dataFatturazione", parametroVal.Value);
//--parametri per report--
//--parametri Per Intestazione Titolo Report--
crFormulaDefinition = crReportDocument.DataDefinition.FormulaFields["Intestazione"];
crFormulaDefinition.Text = "\" " + DateTime.Parse(dataFatturazione.ToString()).ToString("dd/MM/yyyy") + "\"";
//--parametri Per Intestazione Titolo Report--
CrystalReportViewer1.ReportSource = crReportDocument;
private void SetDBLogonForSubreports(ConnectionInfo crConnInfo, ReportDocument crReportDocument)
        Sections sections = crReportDocument.ReportDefinition.Sections;
        foreach (Section section in sections)
            ReportObjects crReportObjects = section.ReportObjects;
            foreach (ReportObject crReportObject in crReportObjects)
                if (crReportObject.Kind == ReportObjectKind.SubreportObject)
                    SubreportObject subReport = (SubreportObject)crReportObject;
                    ReportDocument subReportDocument = subReport.OpenSubreport(subReport.SubreportName);
                    SetDBLogonForReport(crConnInfo, subReportDocument);
private void SetDBLogonForReport(ConnectionInfo crConnInfo, ReportDocument crReportDocument)
        Tables tabelle = crReportDocument.Database.Tables;
        foreach (CrystalDecisions.CrystalReports.Engine.Table tabella in tabelle)
            TableLogOnInfo myTableLogonInfo = tabella.LogOnInfo;
            myTableLogonInfo.ConnectionInfo = crConnInfo;
            tabella.ApplyLogOnInfo(myTableLogonInfo);
Thanks

Without trying to parse through all of your code line by line, you seem to be trying to set the database by connecting to the database directly and then you pass it a datatabe.  You should pick one or the other and try it.
