If a VPN connection exists, it returns true else, false. It makes use of the NetworkInterface class and uses LINQ to loop through all the known network interfaces. This is probably the easiest and most convenient way of determining whether or not you have a VPN connection. NiVPN.AsEnumerable().Any(Function(x) x.Name = "VPN Name") Open the code window and add the necessary Namespace to your project: Imports Īdd the following sub procedure: Private Sub CheckConnection() Start a new Visual Basic Windows Forms project and add two buttons onto the form. The aim of today’s project is to show you different ways you can determine a VPN connection and some methods on how to disconnect and connect to a VPN. RasDial is a wrapper around the Win32 RasDial API, and is typically used in situations where no user interface can be shown. RasPhone is a wrapper around the Win32 RasPhonebookDlg API, and is typically used when an interface may be allowed. And, the getAllNetworkInterfaces method returns objects that describe the network interfaces on the local computer. The NetworkInterface class provides configuration and statistical information for a network interface. The namespace also contains classes that implement the Ping utility that can used to check whether a computer is reachable across a network. NET Framework includes the namespace, which provides access to network traffic data, network address information, and notification of address changes for the local computer. In doing so, geo-restrictions and censorship are circumvented. On the other side, Internet users could secure their wireless transactions with a VPN. VPNs are used to securely connect geographically separated offices of an organization, thus creating a cohesive network. Virtual Private Networks allow employees to securely access a corporate Intranet while located outside the office. This provides a few benefits to applications running across the VPN. A VPN (Virtual Private Network) extends a private network across a public network, and enables users to send and receive data across shared or public networks similar to being directly connected to a private network.
