Client Side IE Controls

I'm quite new to VB..

I'm looking to transfer some code I have that retrieves the windows username to an ActiveX control that I can use within IE

I'm looking to develop a control that will

1: Retrieve Username and copy to textbox
2: Post the username and a password so they can be read by the Request object in ASP.

I've seen some stuff on ActiveX controls.. how do I go about designing this for Internet Explorer???

Thx in Advance..
