API windows socket

Bonjour,

Je suis actuellement en train de faire un petit prog de chat entre 2 pc en reseaux.J essaye donc d associer le tuto sur les socket et celui sur l API WINDOWS sans trop de succes pour le moment.Je n arrive pas a etablir de connexion!Je ne sais pas si j utilise la fonction WSAAsyncSelect corectement.
Je me tourne donc vers vous :
