IIS Site Creation

Question 1:
arrBindings(0).IP = "192.168.1.1"
arrBindings(0).Port = "80"
arrBindings(0).Hostname = "localhost"

THese clearly are parameters for specific fields in the IIS website properties page.
There are other properties that I would like to be able to manipulate as well.

How do we get this information to know what the "read" check box for the Home Directory" tab is?

I just feel like things are kind of "made up" or "declared" but I don’t know from whar "root" value/property

I hope I’ve made enough sense to get some replies.

thanks in advance.
