Внимание!
Имеется два приложения--одно из них серверное(главное), второе - клиентское(не главное). Передача данных т.е. сообщений осуществляется по каналу через протокол NetBios (передача данных вернее сообщений работает хорошо)..Но нужно модернизировать программу т.е. вывести информацию о канале и информацию о сетевом адаптере - пользователю. Как это осуществить?
серверное прил:
