Я получаю сообщение об ошибке при завершении программы. В противном случае он работает нормально.
Setup:
- Visual Studio 2012 (x64 для Windows 7)
- смешанный C++/CLI с машинным кодом DLL (родной код Повысьте Asio)
- CLR консольного приложения связаны с DLLприложение падает при закрытии - с использованием смешанного режима DLL
Когда я " отлаживать»авария соответствующее сообщение:
Unhandled exception ... 0xC0020001: The string binding is invalid
Я нашел этот MS аннотацию, которая описывает ошибку: crashes with 0xc0020001
суммировать говорится это происходит, когда управляемый код неправильно был смешан с неуправляемый код. Однако я не могу определить, где мой код неправильно помечен.
Файл "UnmanagedBoostStuff.cpp" имеет свои настройки свойств как No Common Language RunTime Support.
И я прочитал, что, когда вы включаете заголовок с машинным кодом, чтобы окружать включать заявление, как:
