Sur demande de l'OP, je partagerai mon code de livre d'or.
Classe de message:

J'ai renommé certaines variables et fonctions pour vous donner un sens (traduit du néerlandais en anglais: P) afin que vous puissiez parfois trouver des phrases étranges parce que je viens de faire un remplacement rapide, etc. Amusez-vous avec. De plus, ce n'est pas tout le code car cela me ferait publier comme 20 fichiers de code: P
