Hi,
I am currently developing an ASP.NET website using Visual Studio.NET 2005. I am using the .NET 2.0 framework, VB.NET as my programming language and I connect successfully to a SQL Server 2005 database.  I can select, insert, update and delete data from the database elsewhere in my project, so I know basic connectivity isn't an issue.  The problem seems to be with Crystal Reports. 
I created a folder called 'Reports' in my project and added a Crystal Report file (OpenFiles.rpt) to it.  I designed the report and initally used a hard-coded SQL query as its datasource so I could quickly get the database fields onto the report and preview them.  All worked fine. 
To make the report accessible to the rest of the website, I created an .xsd dataset file containing the three tables (and their corresponding tableadapters) that the report requires and then redeveloped the report using the dataset as the datasource for the report.  After doing this, the preview no longer worked.
Next, I added a page to the website and dragged a Crystal Report Viewer Control onto it.  In the code behind the page I wrote:
Option Strict On
Imports System.Data
Imports CrystalDecisions.CrystalReports.Engine
Imports CrystalDecisions.Shared
Partial Class Reports
     Inherits System.Web.UI.Page
     Private objOpenFilesreport As OpenFilesReport
     Private rptOpenFiles As ReportDocument
     Private strLastErrorMessage As String = Nothing
     Private errLastException As Exception = Nothing
     Dim strFileKey As String
     Dim strJurisdictionCode As String
     Dim strStaffId As String
     Dim strReportId As String
     Private Sub ConfigureCrystalReports()
          Dim reportPath As String = Server.MapPath("OpenFiles.rpt")
          Dim rptopenfiles As New ReportDocument
          rptOpenFiles.Load(reportPath)  <== I checked this during execution and the value correctly points to the OpenFiles.rpt file in the Reports     folder of my project
          Dim ConnectionInfo As ConnectionInfo = New ConnectionInfo()
          ConnectionInfo.DatabaseName = my database
          ConnectionInfo.UserID = login id of user
          ConnectionInfo.Password = user's password
          SetDBLogonForReport(ConnectionInfo, rptopenfiles)
          CrystalReportViewer1.ReportSource = rptopenfiles
     End Sub
     Protected Sub Page_Init(ByVal sender As Object, ByVal e As System.EventArgs) Handles Me.Init
         ConfigureCrystalReports()
     End Sub
     Private Sub SetDBLogonForReport(ByVal ConnectionInfo As ConnectionInfo, ByVal myReportDocument As ReportDocument)
          Dim myTables As Tables = myReportDocument.Database.Tables
          For Each myTable As CrystalDecisions.CrystalReports.Engine.Table In myTables
               Dim myTableLogonInfo As TableLogOnInfo = myTable.LogOnInfo
               myTableLogonInfo.ConnectionInfo = ConnectionInfo
               myTable.ApplyLogOnInfo(myTableLogonInfo)
          Next
     End Sub
End Class
I added a hyperlink to one of the existing pages on the website to navigate to this page with the report viewer on it.  When I run the website in Visual Studio and click on the hyperlink I get the following:
Server Error in '/MyTest' Application.

Any ideas, anyone?
Also, assuming I can get past this error, I will need to figure out how to fill the tables in the .xsd dataset file.  I have written a class for the dataset that includes functions that populate the tables in the dataset from the database by executing SQL queries.  But how do I call these functions at the time the report is run?
This is my first Crystal report written in .NET and I've been struggling with it for days now.  Any help would be most appreciated!
Thanks very much!

hello, the error message is obviously coming from one of the installed mcafee extensions. please directly contact mcafee technical support - they can likely give you more detailed guidance and are the only ones who can fix bugs or make necessary adjustments in the addon.
