If this has been answered before could someone please point me to the thread. Well, here we go. First,I want to be able to determine which Ethernet connection is active. Second, I want to be able to setup the TCP/IP parameters such as static IP address, DNS and Gateway entries. This is running under Windows/XP. The reason for doing this is that I connect multiple ways depending on my location so I want to be able to setup the TCP/IP parms based on what type of connection that I have. Any help and/or examples, hopefully, would be appreciated.

Thank-you for your help. This is good information but I really need the information about determining which connection is active. Actually I am looking for some example code. But I do appreciate the link to some really good information...

Try with Quetannon example by Privalov:

[quote="robink"]about determining which connection is active[quote]

What do you mean 'active'? Do you mean if there is data to read?

By active I mean which TCP/IP connection is active i.e. Wireless, Ethernet, Bluetooth. When I am at work I have three subnets that I work with. I want to find out which one is the active one at start-up and adjust the static IP address to fit the subnet. I have static IP addresses for each subnet. We have some software that is supposed to do this that is available internally within the company but it does not work. I hope I have explained this better. Thanks for any help on this.
