IE toolbar; how to get URL's of displayed pages?

I'm creating a plugin for Internet Explorer which adds a toolbar to the browser. When you click a button on that toolbar I need to know which page is currently being displayed.

I've already found out how to read the url from the Address box of IE, but when a page uses frames, more pages are actually being displayed. I need to know all those pages.

Do I need a handle to the browsercontrol for this or something like that? :confused: I'd appreciate any help. :)

bump :(

I was wondering if you could help me out with my problem, which
is that I don't know how to make a toolbar for internet explorer...
