I work with Visual Basic 2005 Express Edition, and I've been wondering, is there is a way to return the Network Card's IP address? Example:

TextBox1.Text = ([line of code for net card's IP])

So that it shows my card's IP: 192.168.1.8

And also can you find out the strength of a wireless signal (I have a Netgear WG311T) using VB, or do you need some sort of external .exe?

I don't know a whole heap on Visual Basic, so maybe I missed something.

Any help is much appreciated
