Рис. А.12. Окно DirectDraw Advanced Settings
При максимальном уровне отладки каждое приложение DirectDraw, запущенное в отладчике, выдает весьма обширный и подробный протокол. Вывод протокола снижает быстродействие программы, так что максимальный уровень не стоит держать включенным постоянно. С другой стороны, он сильно помогает в затяжной борьбе с DirectDraw. Чтобы показать, насколько подробная информация выдается при максимальном уровне отладки, я приведу отладочный протокол для небольшого полноэкранного приложения DirectDraw. Обратите внимание на то, что листинг раскрывает некоторые внутренние тонкости работы DirectDraw. Подробный отладочный протокол приведен в листинге А.1.
