Winsock erstellen

Hey Leute,
ich hab mich drangesetzt und versucht ein Winsock zu proggen (Visual basic 6).
Es soll Packete lesen (zb. von einem privaten Server; in diesem Fall ein Flyff Pserver) und zurücksenden. Könnt ihr euch mein Code bitte angucken? :D
Seid nicht so streng, bin noch nicht so gut darin! *_*

cout<<"1) Host server"<<endl;
cout<<"2) Join server"<<endl;
cout<<"3) Quit"<<endl;
cin>>choice;
if ( choice == 3 )
exit(0);
else if ( choice == 2 )
{
//Client
cout<<"Enter an IP address, 127.0.0.1 is the loopback address"<<endl;
cin>>ipAddress;
ClientSocket sockClient;
cout<<"ATTEMPTING TO CONNECT..."<<endl;
sockClient.ConnectToServer( ipAddress.c_str(), port );
//Connected
while ( !done )

Das meiste hat nen Kumbel von mir gemacht. Ich hab nur ca. 30% gemacht ^^
Vielen Dank für die Hilfe. Nehme auch gern Kritik an :)
