Effacer les cookie pour InternetExplorer.Application

Question

Bonjour,
J'ai un petit problème avec les cookies qui ce supprime bien mais bizarrement quand je redémarre une fenêtre IE je suis toujours connecter a gmail.

Voila la façon que j&#8217;utilise IE

Dim IE As Object
Set IE = CreateObject("InternetExplorer.Application")
IE.navigate "http://mail.google.com/mail/"
'etc..


Voila le code pour effacer les cookie et tous le reste..

re,

J'ai résolus mes problèmes grâce aux interventions et les  sources de Renfield (une vraie mine d'or).
Donc si vous avez les mêmes problèmes que moi chercher tous ce qui concerne Renfield.
Vive Renfield.

Cordialement,
