Je souhaiterai afficher sur mon formulaire un fichier pdf ou dwg qui fait appel une BD access avec un champ nom de fichier et un autre pour le chemin d'accès des fichiers. J.ai transformé mes fichiers en hyperlien mais j'arrive pas a code pour acceder au chemin d'accés et afficher le fichier. Y'a t'il quelqu'un qui peut m'aider a debloquer cette situation.
Public Num As String
Public NumDocument As String
Public LienImage As String
