capturing word events

[Sanjay Nadimpalli]

I have a javascript on my html page which uses automation to launch word
application. Once the word application is launched, I would like to capture
events like Document Open, Changed, Save and Quit events on the client. How
does one do that? Any help is greatly apprecited.

I know how to do that in my C# program using PIAs and event handlers, but I
am not sure how it can be done in the browser client.

Thanks
San
