Is it posable to use Inet to post a username and password to a asp form login with visualbasic 6?

Using the designer built into VB for creating an IIS application would be very helpful for you.

HTML has an input type for passwords.
You would put the inputs inside an HTML form, and set method="post"

The values will then be in Request.Form("...") where "..." is the name of the control on the web page.
