La critique d'un code comme celui-ci n'a pas sa place ici. Que ceux qui critiquent fournissent leurs sources aussi proprement !
Enfin, même si le code n'est pas de lui, il a le mérite de vouloir faire progresser les autres en ajoutant un code intéressant plutôt qu'un code pourri comme on en voit malheureusement trop.
Cependant, si Scooby1 (l'initiateur de cette page) se souvenait de l'url où il a trouvé ce code, ça pourrait intéresser de connaître quels sont les sites instructifs.
La critique de eyesonlyle ne sert à rien puisse que la réponse a déjà été donnée alors ce qui viennent pour critiquer sont les bienvenues tant que ces critiques sont là pour faire progressées le code sources, sinon aller voir ailleur pour vos conneries. De plus merci de parler Français.
