Browser Helper Object question

[Chocawok]

Hi, Sorry for the cross post.

I've been looking into developing a Browser Helper Object (BHO) for a while
and have made a little
progress.

What I want to do is this:
Get notified when ie goes to a new URL and what it is.
Open new child windows based on this.
Various other things when someone clicks on my toolbar/band

My next task was to create a tool-band/bar to snap into ie's set of
tool bars to give the BHO a GUI. Whilst looking into that I discovered that
when created a tool
band can over ride SetSite.

Does this mean that I can do all I want to just by implementing a tool band?

Either way, how do I get a handle to the window where the HTML is rendered -
as this is where I want my windows to open.

Thanks for any help
