Witam wszystkich programistów!
Dzisiaj po raz kolejny mam problem, tym razem zacząłem się bawić siecią w C++. Zacząłem więc od nauki gniazdek, i odrazu kamień w łeb...

Dodałem do linkowania tę bibliotekę: ws2_32.lib, ale i tak nic się nie dzieje. Zupełnie jakby ją kompilator olewał... W Code::Blocks też nie chciało pójść, jedynie w Dev-Cpp poszło, ale chciałbym żeby też chodziło pod Visual Studio, kumpel ma to samo Visual Studio i mu działa, a nie wiemy czemu nie działa mi...
Byłbym wdzięczny gdyby ktoś potrafił pomóc...
Dobra, problem "rozwiązany". Zmieniłem kolejność includów i działa. W tutorialach jest inna kolejność, nie wiem co jest nie tak... W takiej kolejności działa:
#include <iostream> #include <winsock2.h> #include <windows.h> int main() { std::cin.get(); return 0; }

Dzisiaj po raz kolejny mam problem, tym razem zacząłem się bawić siecią w C++. Zacząłem więc od nauki gniazdek, i odrazu kamień w łeb...

Dodałem do linkowania tę bibliotekę: ws2_32.lib, ale i tak nic się nie dzieje. Zupełnie jakby ją kompilator olewał... W Code::Blocks też nie chciało pójść, jedynie w Dev-Cpp poszło, ale chciałbym żeby też chodziło pod Visual Studio, kumpel ma to samo Visual Studio i mu działa, a nie wiemy czemu nie działa mi...
Byłbym wdzięczny gdyby ktoś potrafił pomóc...
Dobra, problem "rozwiązany". Zmieniłem kolejność includów i działa. W tutorialach jest inna kolejność, nie wiem co jest nie tak... W takiej kolejności działa:
#include <iostream> #include <winsock2.h> #include <windows.h> int main() { std::cin.get(); return 0; }
