Winsock2 connect error

[minlial]

I am using winsock2 to create a tcp stream. My listen function works correctly but every time i try to connect it fails. Can someone tell me why the code below always fails?

sockaddr_in target;

target.sin_family = AF_INET; // address family Internet
target.sin_port = htons (5001); // set server’s port number
target.sin_addr.s_addr = inet_addr ("127.0.0.1"); // set server’s IP
