Programmatically connect Windows VPN invisibly

Question

How do I write code to connect through Windows VPN client?

I want this process to happen invisibly during logon...

Please help..

Thanks

Answer 1

Don't bother with code. You can configure windows to connect automatically to the vpn upon logon.

The Remote Access Service API is what you're after, specifically the RasDial function:

Remember that you must call RasHangUp before your application exits so that the connection is closed cleanly.
