Export to pdf: The system cannot find the path specified.

Hi,

I am having trouble troubleshooting the cause of my error when attempting to export a pdf report.

Dim filename As String

filename = Request.QueryString("report") & "_" & Request.QueryString("user") & "_" & DateTime.Now.ToString("yyyyMMddHHmmss") & ".pdf"

exportPath = Request.PhysicalApplicationPath & filename

Try

myReport.ExportToDisk(ExportFormatType.PortableDocFormat, exportPath)

Catch ex As Exception

Response.Write("Export Error: <BR>")

Response.Write(exportPath)

Response.Write("<BR>")

Response.Write(ex.Message.ToString())

End Try

This code will fail, with the following displayed:

Export Error:

C:\websites\reporttest\reports\testreportbyparam4_batch_20160527151754.pdf

The system cannot find the path specified.

The directory exists.

I am attempting to call my using a vb.net aspx page with a URL like:

http://localhost/reporttest/reports/OpenReport.aspx?report=testreportbyparam4

where the report name and connection parameters are passed in the the Request scope variables

The report testreportbyparam4.rpt exists in the directory

e.g

Dim reportPath As String

reportPath = Server.MapPath(Request.QueryString("report") & ".rpt")

myReport.Load(reportPath)

I have a virtual directory setup to the reporttest folder under IIS.

If I don't catch the error, my stack trace is as follows:

[COMException (0x80004005): The system cannot find the path specified.

I was wondering could it be a permissions problem? I don't really know enough about aspx websites to troubleshoot

I am using Visual Studio 2012, and the the project references the CrystalReportsEngine 13.0.2000.0
