D.5 Comment lire des valeurs REG_MULTI_SZValues

J'ai écris ce script pour aider rpetges dans ce sujet du forum. Cela va lire une valeur dans le registre, du type REG_MULTI_SZ, et l'afficher. N'oubliez pas de modifier là où il est écrit "Modifier ici !" lorsque vous testerez ce script. Les valeurs doivent pointer sur une valeur REG_MULTI_SZ ou l'exemple génèrera une erreur.

OutFile "REG_MULTI_SZ Reader.exe"

Name "REG_MULTI_SZ Reader"
