Thank CodeMercenary (CodeMercenary at hotmail dot com) that provide ms ddk example driver code is wrong for how to write a graphice driver with dx support. he gave me input and provide the ddk example code is wrong.

Now I change the desgin after correct infomations
so it lead to even less overhead of code.
