Небольшое обновление: у меня есть переменная (указатель) с именем m_D3D, которая объявлена ​​из другого файла с именем graphics.cpp. Ошибка возникает, когда в D3DClass вызывается конструктор для инициализации всех переменных значением 0 (NULL). Когда я проверил значение m_D3D по этому указателю, я обнаружил следующее сообщение:

m_D3D CXX0017: Ошибка: символ "" не найден

Пожалуйста, порекомендуйте.

Ваше здоровье
