    I have installed the whole redist package. But i need to include all required dll and I am not able to find refrence of those dll.

    I am getting this error when call the function to export as pdf.

    My requirement is that I export data after filtering according to date. In some date range pdf is exporting successfully without any error.

    But on some ranges of dates LogOn error occurs.

    Following code I am using:

    GenerateCrystalReport generatCR = new GenerateCrystalReport();

    CrystalDecisions.CrystalReports.Engine.ReportDocument reportDocument =

    new CrystalDecisions.CrystalReports.Engine.ReportDocument();

    CrystalDecisions.ReportAppServer.ReportDefModel.Section headersection;

    CrystalDecisions.ReportAppServer.ReportDefModel.Section columnsection;

    CrystalDecisions.ReportAppServer.ReportDefModel.Section rowsection;

    string name = ds_user.Tables[0].Rows[0]["name"].ToString();

    string age_sex = age + "/" + ds_user.Tables[0].Rows[0]["sex"].ToString();

    string email_address = ds_user.Tables[0].Rows[0]["email"].ToString();

    string contact = ds_user.Tables[0].Rows[0]["contactno"].ToString().Replace("+", "");

    string printdate = DateTime.UtcNow.ToString("dd MMM yyyy");

    string daterange = Convert.ToDateTime(tb_from).ToString("dd MMM yyyy") + " To " + Convert.ToDateTime(tb_to).ToString("dd MMM yyyy");


    ISCDReportClientDocument reportClientDoc = reportDocument.ReportClientDocument;

    dataSetReportDetails.WriteXml(HttpContext.Current.Server.MapPath("~/bin/reports/MList.xml"), XmlWriteMode.WriteSchema);

    CrystalDecisions.ReportAppServer.DataDefModel.ConnectionInfo connectionInfo = generatCR.getConnectionInfo(HttpContext.Current.Server.MapPath



    generatCR.SetParameters(reportDocument, name, age_sex, email_address, contact, printdate, daterange);

    downloadPDF(reportDocument, "Details_List" + daterange + ".pdf");

    //function to get connection info for created xml file from dataset

    public CrystalDecisions.ReportAppServer.DataDefModel.ConnectionInfo getConnectionInfo(string xmlFilePath)


    PropertyBag logonInfo = new PropertyBag();


    logonInfo.Add("XML File Path", xmlFilePath);

    PropertyBag attributes = new PropertyBag();


    attributes.Add("Database DLL", "crdb_adoplus.dll");

    attributes.Add("QE_DatabaseType", "ADO.NET (XML)");

    attributes.Add("QE_ServerDescription", "NewDataSet");

    attributes.Add("QE_SQLDB", true);

    attributes.Add("QE_LogonProperties", logonInfo);

    CrystalDecisions.ReportAppServer.DataDefModel.ConnectionInfo connectionInfo = new CrystalDecisions.ReportAppServer.DataDefModel.ConnectionInfo();

    connectionInfo.Kind = CrConnectionInfoKindEnum.crConnectionInfoKindCRQE;

    connectionInfo.Attributes = attributes;

    return connectionInfo;


    //set parameters value in report

    public void SetParameters(ReportDocument reportDocument, string name, string age_sex, string email_address, string contact, string printdate, string daterange)


    reportDocument.SetParameterValue("pname", name);

    reportDocument.SetParameterValue("p_agesex", age_sex);

    reportDocument.SetParameterValue("email_id", (email_address != "" && email_address != null) ? email_address : "NA");

    reportDocument.SetParameterValue("pcontact", (contact != "" && contact != null) ? contact : "NA");

    reportDocument.SetParameterValue("printdate", printdate);

    reportDocument.SetParameterValue("daterange", daterange);

    reportDocument.SetParameterValue("next_page_head", name );

    reportDocument.SetParameterValue("headerlogoPath", (HttpContext.Current.Server.MapPath("~/images/") + "Report-logo.png").ToString());

    reportDocument.SetParameterValue("single", true);

    reportDocument.SetParameterValue("today_date", Convert.ToDateTime(printdate).ToString("dd/MM/yyyy"));

    reportDocument.SetParameterValue("today_date1", Convert.ToDateTime (printdate).ToString("dd/MM/yyyy"));

    reportDocument.SetParameterValue("picture_path", MyImgPath);

    reportDocument.SetParameterValue("picture_path1", MyImgPath);


    //Export to pdf

    public void downloadPDF(ReportDocument reportDocument, string filename, bool mobile)


    MemoryStream oStream = (MemoryStream)reportDocument.ExportToStream(CrystalDecisions.Shared.ExportFormatType.PortableDocFormat);



    HttpContext.Current.Response.ContentType = "application/pdf";

    HttpContext.Current.Response.AddHeader("Content-Length", oStream.Length.ToString());

    HttpContext.Current.Response.AddHeader("Content-Disposition", "attachment; filename=" + filename);






    I find the exception As LogOn Failed in following line-

    It is really difficult to answer the question when basic information is not available.

    Could you provide, version of CR, version of VS, win or web app, a snapshot of error and the sample code.

    And there is a good possibility you are using some third party software or maybe even Business One version.

    Please clarify.

    Crystal Reports version is

    Visual Studio -2012.

    I am using Crystal Reports in web application which has 2 subreports and exporting as PDF file.

    on Local machine it is works fine if I fill dummy parameters in report preview and file path of report dataset file. But After deploying on server, all reports are working fine expect that one.

    At the time of export, it is giving following error message:

    Logon failed.Failed to export the report.

    Error in File testing {F282207C-64BC-43R3-8EB8-562E6FB9643E}.rpt:

    Unable to connect: incorrect log on parameters.

    • 13.0.2 is not supproted with VS 2012. You need atleast 13.0.5.

      I would suggest you to upgrade to SP 10. (13.0.10.)

      Could you elaborate what exactly do you mean by

      if I fill dummy parameters in report preview and file path of report dataset file

      Does your application use datasets to pass the data to the report?

      The error is self explanatory. Logon failed. which means the report tried to connect to the DB or tried to fetch the data or didnt get the data from Dataset and it failed before the export.

      Could you make sure that you are passing the DB logon info to main report and subreport as well.

    But I am using same version of CR with VS 2012 from last one year and It was working fine. Also all other reports in application are not showing any error of this type.

    I wonder this issue is user dependent, For some of our user report downloaded successfully and for some we are getting mentioned error.

    Yes I am using dataset to pass the data to report. (I have checked by debug code and found there is no issue in user's data).

    Actually this report was showing error on development server too. When I open main report preview, a screen displays where I have to pass dummy values to report parameters and it also ask for file path of data set (.xsd). After this report is exported on development server without any error. If I run this application on another system then it does not accept that file path because that was on local system drive to that system and shows 'logon failed' error.

    Would i have to pass DB logon info using code??

    • If the report is using datasets, you do not want to pass it any db logon code.

      It's really hard to help, if you can not / do not want to go to a supported environment. Note that as Bhushan recommended, updating to SP 10 is a trivial process and I'd highly recommend that you do this step.

      Also. Note that now you appear to have at least two issues; Load report failed, Log on failed. Who know what else. Please do update to SP 10, and if there are issues we can troubleshoot those. But at least we will be in a supported environment.

    I am selecting the same range of 30 days. But on some particular dates selection I am getting this problem.

    For eg:- If i select the range 1/04.2014-30/04/2014 then there is no problem but on selection some other date range like 1/08/2014-30/08/2014 'LogOn' error occurs.
