Object reference not set to an instance of an object

[damell]

Hello,

I have a .NET DLL which I am trying to call from an ASP .NET application. The DLL errors (Object reference not set to an instance of an object) when using a function from another DLL which is instantiated once successfully.

This DLL works perfectly when called from a VB.NET application.

ASP.NET:

Private Sub btnSubmit_Click(ByVal sender As Object, ByVal e As System.EventArgs) Handles btnSubmit.Click

Dim objProgram As New WCS_DLL_Interface_Girobank_Split.WCS_DLL_Interface_Girobank_Split
            objProgram.Run("040927", "C:\Inetpub\wwwroot\WCS_ASP_Interface_BulkPayments\App.config")
        End If
    End Sub

VB.NET DLL:

'Successfully creates instance
Dim objDB As New WCS_db_authentication.db

'Loop
'Error Line
strRAN = objDB.getData_ID(strAppPath, "WCS_SP_TMP_Girobank_Split_FindDebt", strWCS_SP_TMP_Girobank_Split_FindDebt)
            
'End Loop

I can't see why this would work in VB.NET and not ASP.NET. It creates the object fine (Even debugging "objDB is null" returns false).

Any one any ideas?

Cheers...

Seems it was a problem with a database function in wcs_db_authentication after all. Didn't have the correct permissions to connect.

Thanks for the reply.
