Why socket(PF_INET,SOCK_STREAM,0) returns -1?
I trying to create a socket application on visual studio c++, but I can't.
The problem is int listen_sock = socket(PF_INET,SOCK_STREAM,0) returns -1 and I don't know why...
What am I doing wrong?

You should print the error (using GetLastError). I suspect you are not initializing things:
WSADATA wsaData = {0};
WSAStartup(MAKEWORD(2, 2), &wsaData);

What does WSAGetLastError return? Did you call WSAStartup before doing this call?
