Un petit renseignement

Bonjour

Copie le code qui suit dans un module de ta base de donnée
Ensuite il te suffit d'appeler la fonction "test()"

PS : je ne sais plus d'où vient le code mais il n'est pas de moi...

Bonjour à tous.

Comment puis-je récupérer l'IP d'un ardinateur dans une variable dans Access
97 ?

Merci d'avance
