Winsock help

Alright, i'm not sure about the rules and sections..
I just registerd so I am new :p
Im also kinda new to vb..
I have both 6.0 and .NET but I am not sure which one to use :O
It seems like 6.0 has many more resources, but .NET is easier to use..

Anyway, to the point..

I want to create a program like the one below ->
http://empty-pixels.net/mass/gallery/ta.JPG

I want it to send the username and pmno to the website of my choice..
Starting at 1 and ending at 99999

If 1 = Successful then; Load the site displaying the successful login from the site
If 1 = Invalid then; +1 -> check #2..

If 2 = Invalid then; +1 -> check #3..

If 3 = Invalid then; +1 -> check #4..

I know I am speaking in a hybrid language, but I hope it makes sense..

I guess really I just need help understanding Winsock;
and its association with VB..

I have msn, I am online 24/7 :)
If anyone can provide some Live help please add me..
[email protected]

I don't want to feel like a leecher or anything..
I just have absolutely no idea where to start..

I don't even really understand how to get it to read from txtBox1..

Please help me if you can ^^

Thank you.

Regards,
