we have diff. databases outside our DNN db.  example: ordering, warehouse. ect.   I can add the connections in the web.conf. but how would I get the DataContext.Instance() to point to one of those db or can you not use this class method.  we will be calling primarily Stored Procedures.

   Public Shared Function GetEntry(ByVal entryId As Integer, ByVal moduleId As Integer) As ApplicationsInfo
            Dim entry As ApplicationsInfo

            Using ctx As IDataContext = DataContext.Instance()
                Dim rep = ctx.GetRepository(Of ApplicationsInfo)()
                entry = rep.GetById(entryId, moduleId)
            End Using

            Return entry
        End Function

thanks

Doug

There's an overload of <code>DataContext.Instance</code> that takes the connection string name.

thanks for the quick reply and I see the fuction, but how would I code that?

        Public Shared Function Instance() As IDataContext
        Public Shared Function Instance(connectionStringName As String) As IDataContext

DataContext.Instance("NewConnectionString") doesn't work.

I would expect <code>DataContext.Instance("NewConnectionString")</code> to work, what error are you getting?
