Все, что необходимо начинающему и опытному программисту

И, наконец, чтобы наше окно лучше смотрелось, заменим стандартный белый цвет фона на серый:
// wcex.hbrBackground = (HBRUSH)(C0L0R_WIND0W + 1);
wcex.hbrBackground = (HBRUSH)GetStockObject(GRAY_BRUSH);
Полный исходный текст нашего приложения приведен в листинге 3.53.
