我的水晶报表无法在线使用 [英] My crystal report is not working in online

问题描述

在我的项目中，我正在使用Crystal报表.我为负载报告提供了以下编码

In my project I am using Crystal report. I give the following coding for load report

rptdoc = new ReportDocument();    rptdoc.Load(Server.MapPath("LedgerReport.rpt"));    rptdoc.SetDataSource(ds.Tables[0])   rptdoc.ExportToHttpResponse(ExportFormatType.PortableDocFormat, this.Response, false, "LedgerReport.pdf");
CrTables = rptdoc.Database.Tables
connectdatabase1();
CrystalReportViewer1.ReportSource = rptdoc;

它在本地计算机上正常工作.但是在网上错误显示是这样的

推荐答案

根据google，这意味着未注册COM dll"Exportmodeller.dll"和"Tslv.dll"，或者您的服务器上可能不存在.

According to google, this means the COM dlls "Exportmodeller.dll" and "Tslv.dll" are not registered, or perhaps not present, on your server.

我认为由于server.mappath函数会导致错误，它将返回物理路径.
只需更改虚拟路径，例如http:\\ domain \\ foldertree \\ report.rpt

i think you will get error due to server.mappath function .it will return physical path.
just change with virtual path like http:\\domainname\\foldertree\\report.rpt
