Ĺadny brzuch
utworzyłem taki program , który ma utworzyć socketa, ale pokazują się błądy w komplikacji, co mam źle?

mam najnowszego Dev'a c++
hInstance -> hThisInstance
potem Project -> Project options -> Parameters -> Add library or object -> znajdujesz plik "libws2_32.a" z katalogu dev-cpp\lib :)
Jeszcze tak na przyszłość, to napisz jakie to błędy.
A tak poza tym to kompilacji, nie komplikacji. ;)
