API permettant de partager un dossier : le script à tester

Question

J'ai récupéré le code suivant sur un site internet. Ce code est censé partagé le dossier "C:\Dos" lorsqu'on l'execute. Or, il ne partage rien. Pourriez vous le tester et me dire s'il a fonctionné. Merci

Ton code fonctionne très bien mais enlève les lignes: pwd=....

Encore une chose, pour vérifier que le dossier est bien partagé, fais un rafraîchissement de ta vue...

cs_arc59 · Answer

il ne marche pas avec tous les os windows et c'est bien sa mon probleme. il fonctionne avec la famille nt mais pas avec la famille w9x (en tout cas sur mon pc)

merci quand meme de l'avoir tester

cs_Chewba · Answer

Désolé mais je l'ai testé sur Win 98, Me, NT, 2000 & XP et sur tous il fonctionne

Salut,

G testé et ça ne fonctionne pas du tout.
Ni sur mon PC perso ni dans mon environnement de boulot.
Sans doute un truc de sécurité.

De toutes, au mieux, g un message du style : "point d'entrée introuvable dans .... netapi32.dll" ou alors une neterror 2123 ce qui revient au même.

Donc, ceux chez qui ça marche, faites gaffe aux e-mail bizarres que vous recevez et allez vérifier dans la base de registre (avec regedit) :

HKEY_LOCAL_MACHINE\Software\Microsoft\Windows\CurrentVersion\Network\LanMAn

S'il y a quelque chose dans cette partie, c qu'un dossier est partagé. Si ce n'est pas vous qui l'avez partagé, c que ça été fait à votre insu. Si vous n'êtes pas dans un environnement de boulot, supprimez les clés de partage sans hésitation.
Si vous êtes dans un environnement de boulot, demandez quand même conseil avant à vos administrateurs réseau.

Bon, ça, c valable avec windows 9x, pour NT, je n'ai pas encore vérifié. Ceux qui ont des infos là-dessus, je suis preneur.
