Bonjour,

Je souhaite envoyer des informations en post dans une url.

Pour cela, j'ai utilisé l'objet InternetExplorer et le
code suivant:

Sub ie()
Dim objie As New InternetExplorer
objie.Visible = True
objie.Navigate "http://portcal/a.asp"
End Sub

Mais cela ne fonctionne pas,

Quelqu'un pourrait-il m'aider?

Merci

Denis

Merci,

je vais tester.
