Tsaiper © (2004-04-28 12:23) [0]Уважаемые мастера!
Очень нужен файл DDUTIL.PAS из комплекта заголовочных для DirectX7!!!
Если у кого есть, пришлите плз на мыло, или скажите где скачать! На jedi-delphi его нету!
Очень надо!

Опс... Не обратил внимания... А зачем тебе именно DX7?

ГИГАНТСКОЕ СПАСИБО!
2MeF88:
Я начинающий программист-любитель, взял книжку Краснова (графика в проектах Delphi), там используется именно DX7. Вот. Все примеры на нем.

А если бы попросили DirectShow9.pas размеров 1,3Мб - ты бы его тоже на форум запостил?
> там используется именно DX7
Понятненько... Пора бы уж Краснову и под DX9 переписывать книгу ;)
