salut
il y a plusieurs moyens de faire cela
soit la dite application génère un enregistrement d'info dans le registre, auquel cas il suffit de vérifier si l'entrée du registre existe et si l'application associée est toujours présente dans le dossier

l'autre moyen, plus direct est de controler la présence de l'exe concerné sur le disque en parcourant l'ensemble des répertoires... mais cette dernière méthode peut être tres tres longue...

as tu plus d'info sur l'appli a chercher ?

En faite c’est simple, j’ai une apli qui lance quelque exe  est pour sa je veux savoir si l’un deux existe (est installé) sur la machine alors j’éviterai de l’installé, j’avez pensé a active directory mais je ne sait pas ou et comment accéder au variable concernant les programme, si tu peux m’orienté se serai cool de ta part. Merci<?xml:namespace prefix = o ns = "urn:schemas-microsoft-com:office:office" /??>

pour ce qui est de chercher dans Active Directory, encore faut il que ton appli soit publié dans ActiveDirectory.
Pour ma part, je te conseille plus d'aller chercher dans le registre Windows.

Trouves ci dessous une classe que j'utilise régulièrement pour lire / écrire dans le registre.
