加载报告时我的asp.net报告出现问题 [英] problem on my asp.net report at the time of load the report

问题描述

你好，

当我将项目放在远程站点时，它显示错误，并且错误是:-

Hello,

When I put my project in remote site it is showing error and the error is:-

CrystalDecisions.Shared.CrystalReportsException: Load report failed. ---> System.Runtime.InteropServices.COMException: Invalid file name. at CrystalDecisions.ReportAppServer.ClientDoc.ReportClientDocumentClass.Open(Object& DocumentPath, Int32 Options) at CrystalDecisions.ReportAppServer.ReportClientDocumentWrapper.Open(Object& DocumentPath, Int32 Options) at CrystalDecisions.ReportAppServer.ReportClientDocumentWrapper.EnsureDocumentIsOpened() --- End of inner exception stack trace --- at CrystalDecisions.ReportAppServer.ReportClientDocumentWrapper.EnsureDocumentIsOpened() at CrystalDecisions.CrystalReports.Engine.ReportDocument.Load(String filename, OpenReportMethod openMethod, Int16 parentJob) at CrystalDecisions.CrystalReports.Engine.ReportDocument.Load(String filename) at Crystal_Report_CommonReport.Show_Data

加载(字符串文件名). 我为加载报告编写的代码是:-

The code which I have written for load the report is :-

ReportDocument boReportDocument = new ReportDocument();
boReportDocument.Load(Server.MapPath("RptCustomerDeposits.rpt"));

还有其他加载报告的过程，或者我将做哪些更改?

请帮帮我.

在此先感谢.

Is there any other process to load the report or what the changes I will Do?

Please help me.

Thanks in Advance.

Hi,

private void AddParameter(ReportDocument reportDocument, string value, string parameterName)
    {
        ParameterFieldDefinitions prmDef = reportDocument.DataDefinition.ParameterFields;
        ParameterValues prmVal = new ParameterValues();
        ParameterDiscreteValue prmDiscreteVal = new ParameterDiscreteValue();
        prmDiscreteVal.Value = value;
        prmVal.Add(prmDiscreteVal);
        ParameterFieldDefinition prmFD = prmDef[parameterName];
        try
        {
            prmFD.ApplyCurrentValues(prmVal);
            prmFD.ApplyDefaultValues(prmVal);
        }
        catch (Exception)

        }
    }
    protected void Page_Load(object sender, EventArgs e)
    {
        ReportDocument crpt = new ReportDocument();
        string rptLoc = String.Empty;
        //DataSet1 ds = new DataSet1();  // Had already created a Dataset?

        CrystalReportViewer1.ReportSourceID = "CrystalReportSource1";
        CrystalReportSource1.Report.FileName =
                               Server.MapPath("") + "\\Reports\\RptCustomerDeposits.rpt";
        rptLoc = CrystalReportSource1.Report.FileName;
        crpt.Load(rptLoc);
        crpt.SetDataSource(ds);
        AddParameter(crpt, "12345678", "CardNumber");  // Sample to call AddParameter
        CrystalReportViewer1.ReportSource = crpt;
    }
