尝试将报告源作为PDF .Net导出到磁盘时，Crystal Report Viewer使应用程序崩溃

Question

I'm trying to export the reportsource of a crystal report viewer in .Net 1.1 onto disk as a PDF using

CrystalDecisions.CrystalReports.Engine.ReportDocument cr = (CrystalDecisions.CrystalReports.Engine.ReportDocument)crvView.ReportSource;
cr.ExportToDisk(CrystalDecisions.[Shared].ExportFormatType.PortableDocFormat, @"C:\Temp\Temp.pdf");

I know it's the "cr.ExportToDisk..." line thats failing, but dont know why. Ive checked to make sure the Crystal Report versions are the same on the client machines and they are.

Sometime i get the message "Memory could not be read at source...." and the application completely crashes, and other times the app crashes without the message.

Any ideas on why this happens and how to fix it would be greatly appreciated.

Cheers

Answer 1

您可以检查以确保要尝试导出到的位置的安全权限相同。

Answer 2

Are you able to print these "faulty" reports? If so, have you tried printing to CutePdf which might allow you to at least work around the issue temporarily.
