bonjour tout le monde,
je me confronte à un léger problème.
je veux envoyer 4 valeurs dans le nono.
tant que j'en envoie 3, c'est bon, après c'est la cata, problème de byte?
les valeurs sont des int (ex : 250-1250-75-990)
si vous avez une idée, car je dois pouvoir envoyer par la suite entre 6 et 12 valeurs
