Как я посидел и посмотрел, там куча хлама который не нужен, хуков процедур как таковы нету кроме AddNetworkQueue, я так понимаю тут перехват пакета идет?
Еще нашел bool SetHooks(void)
Жаль нет коментов к коду(
Не понял еще зачем ето?
Оффтоп

И что это за дрянь?

Пример то замечательный,но очень трудно его вкурить для начала.

Не знаю, будет ли пахать у меня такой код:
еще не поставил билдера под сишку(скачивает) а хочу спросить уже))
