interesting browser development questions

[Peter Chiu]

Hi,

I want to write an application that would get notified once the browser
changes the URL location. I have the following 2 problems:

1. How does my app get notified once the URL has changed?
2. If I know the URL has changed, how do I retrieve the new URL?

I have no answer for #1.

For #2, with IE4 or above, because of its Windows shell integration, I can
use the ShellWindows collection to enumerate all the IE4 windows and get the
URLlocation. However, how do I do the same thing with Netscape Communicator
or IE3?

Any info is highly appreciated!!

Thanks.
