I am trying to connect to a Crystal Report 10 from a web application written in VB.NET. It will connect correctly if I hardcode the path like C:\reportname.rpt, but when I try and put in the web path it will not work. It says "unspecified error". I have tried changing the direction of the slashes from / to \, but still get the same error. Below is the code I am using to write the path.
crDoc.Load("http://" & LCase(Request.ServerVariables("SERVER_NAME")) & "/prGraph.rpt")
Does anyone know how to fix this?

Have you tried Server.MapPath()? Also, you can have problems with running web apps under the file system method (where it puts the :9999) in the URL. There is a fix for this if you upgrade to VS SP1 and set the root folder, but I haven't tried it yet.

I was able to use crDoc.Load(Server.MapPath(HttpRuntime.AppDomainAppVirtualPath) & "\pr\prGraphMean.rpt") to get the report to load; however, instead of the graph displaying it is just listing the name of the crystal report object like below
CrystalReportViewer -
CrystalReportViewer1
Any thoughts?

Hmmm.. I've seen this before, but don't remember how to resolve it. I think it's either an installation problem (try reinstalling on the server) or a permission problem where you can't reference the charting DLL. Try reinstalling to make sure all the DLLs are there and you have permission to access them.
