Bonjour,
la base de données de mon application est sous forme de fichiers .zip
j'ai créer un code pour dézipper en fichier .txt puis un autre pour insérer les fichiers .txt sous MySQL
et pour actualiser la base j'ai créé un bouton dont l'action est de faire tout les étapes dézipper---->insérer dans une table MySQL
le problème c'est que quand je clique sur le bouton ça donne cette erreur ::
