Language Conversion - Toggling NIC

As part of my program I need to be able to programmatically control (enable/disable) the network cards of the computer. I understand that if I use DHCP enabled network cards I can control them using WMI. But unfortunately I need to use static IP addresses, which renders this method redundant.
Through searching the web I have found this app which does exactly what I want, unfortunately it is in C# and I have very little experience of this language. Could anyone convert this into a VB6 app or give me examples of how to do this in VB6
