Visual Basic / VB.NET : Comparison of files

Description

C'est un petit programme qui comme son nom l'indique compare deux fichiers à l'octet et que j'ai fait il y a plus d'un an.

Toutes les fonctions sont basic car je n'en étais qu'a mes débuts dans Visual Basic et donc je ne vois pas la nécessité de commenter le code.

Toutefois s'il vous faut un renseignement ou autre je suis là.

Conclusion :

Ce programme est loin d'être parfait, je m'en rend bien compte mais il ne tient qu'a vous de l'améliorer.

Le système pour enregistrer une ListBox vient de ce site ainsi que le système pour désactiver la croix du formulaire.
