WallPet, please use your brain. It's not as hard as you think.
You know, I've started learning programming with VB.Net, then I realized that it's pretty easy, and not as efficent, professional as other programming languages. I just want to say that try to KEEP AWAY from VB.Net. Anyways if you'd like to stay at such an easy programming language as VB.Net, try C#. It's almost equal to VB.Net, except it's syntax.
With that loooong off topic text, I just wanted to say, that when I was learning programming, and I didn't know how to do something, I just googled it up, and tadaaa! The magic happened. I was suddenly able to do it! In your case, you'd like to start TClient with some specific parameters.
page explains how to do it.
So you would write something like:
Code:
Process.Start("TClient 84.4.111.111 1234")
.
See it? It's not hard. Next time google it up before you bring yourself into a such awkward situation.
