Current Setup

_____________

1. I have WebSite in ASP.NET Visual Basic which works fine and is connected to MySQL Database, using MySQl Connector 6.6.4 64 bit

and is using a connection string,defined in web.confg.

  2. I am using a Crystal report( It is very complex report, so cannot dare to redo it). Data Source for the report is set using a connection string

DRIVER={MySQL ODBC 5.2a Driver};SERVER=Licensedb;DATABASE=License;pwd=root;PORT=3306;OPTION=3 and this report is called from website using the below code

             Dim crystalReport As ReportDocument = New ReportDocument()

            Dim repPath As String = Server.MapPath("~/Reports/") + "LicenseReport.rpt"

            crystalReport.Load(repPath)

            CrystalReportViewer1.ReportSource = crystalReport

            crystalReport.SetParameterValue("InstanceID", CInt(Session("sessionInstanceID")))

            crystalReport.Refresh()

            crystalReport.SetParameterValue("InstanceID", CInt(Session("sessionInstanceID")))

            CrystalReportViewer1.Visible = True

3. The above setup works fine, when I run the website from Visual studio 2010. But when i use IIS 7, the aspx page having crystal report viewer control load and its blank.

However it work very well from studio it self.

4. So I changed the setup in point 2, by having a ODBC Data source defined. And changed the report accordingly. It work fine in Visual studio , but from IIS

it gives error "Failed to Open Connection, Failed to Open Connection <Crystal Report File name.rpt>"

5. I tried creating a System DSN and same connection string in IIS Application Connection string. But nothing changed.

Please can anyone point in correct direction. I must admit this is my first website development work, so I might have overlooked some minor details.

Any help would be much appreciated.

Thanks
