je realise une application de type chet,client/serveur j'ai fait une librairie qui contient toutes les methodes ,j'ai suivi l'exemple du site.http://www.supinfo-projects.com/fr/2004/socket%5Fdotnet/4/
J'ai deux formes,chaque contient deux riches textbox ,un bouton send et un bouton receive
Voici le code de la librairie.
