J'ai besoin d'un programme pour remplacer le fichier, mais parfois un processus le verrouille. Comment vérifier quel processus verrouille un fichier et comment le déverrouiller? Quelles fonctions dois-je utiliser?Quel programme verrouiller le fichier
J'ai trouvé sur Internet un tel code, mais ça ne marche pas.

cela sonne comme vous voulez quelqu'un pour faire le travail pour vous !! recherche de "vérifier si le fichier est en cours d'utilisation" ou des termes similaires sur google, je suis sûr que vous trouverez suffisamment d'informations ... – ComputerSaysNo
