Доброго времени суток всем
использую Microsoft Research Detours Package, Version 2.1.
пытаюсь перехватить сабж
вот код

Приложение куда внедряется Dll не мое
После вызова функций Send SendTo гдето в коде приложения возникает ошибка :
A buffer overrun has occurred in progarm.exe which has corrupted the program's internal state. Press Break to debug the program or Continue to terminate the program.
For more details please see Help topic 'How to debug Buffer Overrun Issues'.
в отладчике обнаружил что все падет на функции _crt_debugger_hook
Подскажите в чем может быть проблема и каково ее решение? |
