Question

Does anyone here have experience with/in developing IE extensions that can share their knowledge? This would include code samples, or links to good ones, or documentation on

Answer 1

I've been working with IE's webbrowser control for years now, and over the course of them, one name comes up over and over again with helpful postings: Igor Tandetnik

If I were developing an extension, I would target a BHO, and start googling for:

BHO Igor Tandetnik

OR

Browser Helper Object Igor Tandetnik

His postings are often very detailed, and he knows what he is talking about.

You're going to find yourself up to your ears in COM and ATL programming. For a sample walkthrough, check out: http://msdn.microsoft.com/en-us/library/ms976373.aspx
