programme client/serveur en C++ problème

Question

J'ai créé un programme client et serveur dans des sockets i = on windows. J'ai un problème quand j'exécute le programme aucun message n'apparaît sur la fin de serveur et après que le programme se termine. Data envoie au serveur mais il ne répond pas en arrière.

je suis coller mon code ci-dessous

Votre aide est très appréciée, il ne fonctionne pas sur mon n = machine à certaines personnes disent que ce code fonctionne bien sur leurs machines. Je l'ai utilisé Visual Studio 2005 pour développer cela et mon OS est Windows 7.
