Я только начал сам учить Directx и пройдя уже не мало проблем,никак не могу нарисовать полигон!   
Скачал книгу Горнова,дошел до создания полигона,весь код просто слизал с книги - полигон не выводиться.

Решил что проблема в книге потому-что нашел не мало плохих коментов о книге.
Нашел другую,та же проблема.Все сделал,опять слизал код с книги,и все равно полигона нету! =(

Может проблема в настройке Студии,правильном подключении библиотек?
(У меня была проблема с подключением d3dx9.h/lib,пришлось указывать полный путь,иначе не работало!)

Может я не там вызываю нужную функцию,код в книгах не описывал сам _tWinMain.
Help!

А задал ли ты пути в настройках проекта?

По поводу рендеринга, начнем с того, что инициализируешь ты переменную pVertices, а рендеришь неинициализированную buffer

Проблема решена.
Ошибка была в этой строке #define D3DFVF_CUSTOMVERTEX (D3DFVF_XYZRHW,D3DFVF_DIFFUSE)

#define D3DFVF_CUSTOMVERTEX (D3DFVF_XYZRHW|D3DFVF_DIFFUSE)
