Re: Interface Graphique : Evenement KeyEvent

Bonjour,

Le mot de passe récupéré par un champ texte qui se trouve dans une interface graphique est stocké caractère par caractère dans un fichier texte avec le Relative TimeStamp : 2011-07-06 15:24:16.876

Example Demandé: Mot de passe tapé par l'utilisateur : abc

Fichier Correspondant contient :

2011-07-06 15:24:16.876 a
2011-07-06 15:24:16.878 b
2011-07-06 15:24:16.879 c

Mon souci c'est que le fichier affiche que le dernier caractère saisi dans le champ password.

Example Réel: Mot de passe tapé par l'utilisateur : abc

Fichier Correspondant contient :

2011-07-06 15:24:16.879 c
