Crystal Reports on ASP .Net

[jmerencilla]

hi. i made a simple web app with a crystal report file which uses an SQL server stored proc. however, every time i try to load the report i get the error below mentioning an invalid path in my drive D. my asp .net files are all located on c:/inetpub/

http://wwwroot/sample

folder, none are located on drive D. i tried testing it using a new windows app project and it worked perfectly fine. can somebody outhere help me trace the source of this error? thanks.

here's my code on the Web form:

Protected WithEvents CRptViewer As CrystalDecisions.Web.CrystalReportViewer

Private Sub Page_Load(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles MyBase.Load
Dim objCRpt As New SampleCRpt()

CRptViewer.ReportSource = objCRpt
End Sub


and here's the error on page load:

Could not find a part of the path "D:\".

It sounds like a security error.
U probably are trying to reach something located on your D drive.

Try giving the 'List Folder Contents' access to your ASPNET user.
If the error stops, then it means u are using something on the D:\somefolder\somefile.xpto, and the ASPNET user doesn't have premission.
If the error changes, then u'll have to find out the exact place where the ASPNET is trying to read or write.
If the error presists, I'll have to keep looking for the solution.

Hope this helps, NetAngel
