Bonjour,

Je cherche à appeler un programme externe depuis un service.
Quand j'éxecute le bout de code dans un prog python classque, ça marche
Le même bout de code dans un service ne m'appelle pas mon prog externe
j'ai joué avec PMIDI en googlant un peu pour me prévenir de l'activité du service

Le but du service est de vérifier si une appli est bien ouverte et qu'elle renvoie quelque chose sur le socket

Code : Sélectionner tout - Visualiser dans une fenêtre à part
