>I'm not entirely clear about what you want to achieve (or why you would *not* want the compiler to reject invalid fields) but setting Option Strict Off and casting to Object will stop the compiler complaining. You would then need to catch attempts to use invalid properties:

Dim oProcess As Object = New Something()
>        Try
>            Dim s As String = oProcess.oLabel.oCity
>            'OK
>        Catch ex As Exception
>            ' No such property or field
>        End Try

Ok, thanks
