Lee,
I am sorry, but I think you will need to post this question to the MHDDK forum. I have given that link above in my last post. The Engineers that monitor that forum are more qualified to answer DDK questions since they are the ones that write the examples and work with it daily. The DDK forum is the best place to get a response for DDK questions. Please repost this question there.
Regards,
Jesse O.
