Connessione a internet

[stefano3]

Vorrei fare un collegamento a internet da Visual Basic senza passare attraverso alla finestra di connessione di windows.
Qualcuno sa quali comandi devo inviare al modem per l'handshake?
Ciao
Grazie

ho trovato questa API

' Name: Automatic Internet Dialup
' Description:Most code snippets simply 
'     show you how to display
a connect dialog. The problem with this is that 
it doesn't force a dial-up and won't alert you 
when a connection is established.
This code solves those problems by using Internet 
Explorer's own 'automatic dial-up' settings 
(Control Panel >> Internet options >> Connections).
It utilises two little-known API calls that can 
automatically connect / disconnect from the 
default connection.
Note: If the 'Never Dial a Connection' option is 


selected, this code will not be able to connect. 
    I came across this API awhile ago when my friend 
    suggested a forced dialup and gave me this tip. 
    It's actually pretty helpful.
