Sto provando il seguente costrutto:

Private Sub Button1_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) _Handles Button1.Click

Dim body As String = TimeOfDay
Dim myWebClient As New System.Net.WebClient

myWebClient.UploadString("www.........it/script.php", "POST", body)


End Sub

ma mi da errore: impossibile stabilire connessione
