COM Interop problem

Guys

I'm getting an unusual error when trying to pass an adodb.recordset between to .vb files. The first file is wrapper for some old asp pages. It's calling a function in a data access assembly. It should be returning a recordset that in turn is returned to the calling asp page.

The error I'm getting is:

Microsoft.VisualBasic error '80020007'

No named arguments.

Never seen this before, and besides, i should have to use named arguments!

Calling ASP code:

Set objInt = Server.CreateObject("InteropServer.InteropServer")

Set Return2 = objInt.ReturnRecordset2("Pr_InteropTest","5")

Return2.Open

Do While Not Return2.EOF
            
    Response.Write Trim(Return2.Fields(0).Value & "") & ", " & Trim(Return2.Fields(1).Value & "") & "<br>"

Return2.MoveNext

Loop

Wrapper code:

Public Function ReturnRecordset2(ByVal p_strSQL As String, ByVal p_strRole As String) As ADODB.Recordset

        Dim objRS As New ADODB.Recordset()

        Dim Role As String
        Role = p_strRole

        Select Case Role
            Case 1
                DalRequest.Role = DalRequest.RoleObject.DOTNETOpen
            Case 2
                DalRequest.Role = DalRequest.RoleObject.DOTNETSecure
            Case 3
                DalRequest.Role = DalRequest.RoleObject.DOTNETLog
            Case 4
                DalRequest.Role = DalRequest.RoleObject.ADOOpen
            Case 5
                DalRequest.Role = DalRequest.RoleObject.ADOSecure
            Case 6
                DalRequest.Role = DalRequest.RoleObject.ADOLog
        End Select

        Dim DataProvider As AbstractProvider = DALFactory.GetProvider(ProviderType.Sql, DalRequest.Role)

        DalRequest.Command = p_strSQL

        objRS = DataProvider.ExecuteADO()

        Return objRS

    End Function

Data Access Code:

Public Overloads Overrides Function ExecuteADO() As ADODB.Recordset

            Dim objConADO As New ADODB.Connection()

            Dim p_objConsumer As New ADODB.Recordset()

            objConADO.Open(ConnectionString)

            Try

                p_objConsumer.Open(DalRequest.Command, objConADO)

            Catch e As SqlException

                Throw e

            Finally

                ':: Disconnect the recordset
                objConADO.ActiveConnection = Nothing
                ':: Close connection
                objConADO.Close()

            End Try

            ':: Return recordset
            Return p_objConsumer

        End Function

I should point out that that both the wrapper and the data access assembly are registered for COM Interop. When I run SQL trace I can see that the code is getting as far as executing the stored procedure (p_objConsumer.Open(DalRequest.Command, objConADO)) above.

Any help would be greatly appreciated.

TIA
