Ошибка Type в DLL   Найти похожие ветки 

← →
Jim^sz ©   (2004-07-16 18:57) [0]

Я создаю DLL, в ней Type (type options=record),
и 4 функции
1: Загрузка файла ( с настройками Type)
2: Сохранение файла ( с настройками Type)
3: Применение настроек (с Type в компоненты)
4: Чтение настроек (с компонентов в Type)

И при загрузке настроек или применении их возникает ошибка
Access Volation Read of adress ...

Чё за ерунда.
