Here is some of my code using a datareader... what is the strataframe equivalent to a datareader?

            Using conn As New SqlConnection(ConnectionString)

                Dim cmd As New SqlCommand



                cmd.CommandText = StoredProcedureName

                cmd.CommandType = CommandType.StoredProcedure

                cmd.Connection = conn



                cmd.Parameters.AddRange(params)

                conn.Open()



                Dim reader As SqlDataReader = cmd.ExecuteReader()



                While reader.Read

                    msLocationName = reader("LocationName")

                    miLocationID = reader("LocationID")



                End While



                reader.Close()

                reader = Nothing

                conn.Close()

            End Using

Thanks

That method will always block... the callback is used for you to provide a method that should be called if you are using Query Notification Services and the server raises the DataChanged event.  If you're not using QNS (which you probably aren't) then just pass in Nothing every time.
