水晶报表

Question

我将 ASP.Net 应用程序从 .NET 1.1 升级到 .NET 2.0。所有网页仍然可以正常工作，但无法加载 Crystal Reports。

堆栈跟踪：

Load report failed.
StackTrace:    at CrystalDecisions.ReportAppServer.ReportClientDocumentWrapper.EnsureDocumentIsOpened()
   at CrystalDecisions.CrystalReports.Engine.ReportDocument.Load(String filename, OpenReportMethod openMethod, Int16 parentJob)
   at CrystalDecisions.CrystalReports.Engine.ReportClass.Load(String reportName, OpenReportMethod openMethod, Int16 parentJob)
   at CrystalDecisions.CrystalReports.Engine.ReportDocument.EnsureLoadReport()
   at CrystalDecisions.CrystalReports.Engine.ReportDocument.SetDataSourceInternal(Object val, Type type)
   at CrystalDecisions.CrystalReports.Engine.ReportDocument.SetDataSource(DataSet dataSet)

有人知道为什么加载不出来吗？

架构：Windows Server 2008 (IIS 7)

调用报告的代码：

ReportClass ApprovalPage=new CustomerJobLabelApprovalMod();
ApprovalPage.SetDataSource(reportDataSet);

CustomerJobLabelApprovalMod 的代码：

Answer 1

稍后进行大量艰苦的谷歌搜索......

我必须授予Windows\Temp 的网络服务权限，因为 Crystal Reports 获取该用户，而不是被模拟的用户（具有管理员权限）。所以该目录，而不是 IIS 目录，是正在使用的那个。

这很令人沮丧，但现在可以了！

Answer 2

我似乎记得不久前做过这个，我在 web.config 中找到了一些对旧 Crystal Reports 内容的引用。
