c'est un peu comme faire une calculatrice, on ws'en sert pas tous les jours une fois qu'elle est faite ;)
pour revenir au sujet, les case en cascade sont dégueux, il aurait suffit de faire un enum pour les couleurs et de l'affecter directement.
meme remarques que Kriss sinon:
pas de commentaires, des variables a déchiffrer.
aucun renommage des controles, pas d'intelligence dans le code.

Car chacun peut écrire un source différent ce qui permet de voir plusieur façons d'arriver à un résultat.
Par contre, des codes sources qui sont les même, ça, ça serrais vraiment grâve.
Ici, je ne sais pas si c'est le cas.
L'auteur est content de son travail et le partage.
Par contre l'auteur à fait quelques erreurs :
->il s'est trompé de niveau
->il n'a pas commenté son code
->aucun nom de variable ne fait penser à son contenu
->val(ListBox1.SelectedIndex.ToString) : Convertion d'un INTEGER en STRING puis on extrait la valeure de la chaine ? (est-ce ça ?)
Cela fait donc 5/10.
Bonne continuation en VB.
