Scripting Word document inside iframe

Hello,
I have a web page that contains an iframe, and the "src" of the iframe is set to a word document.
So the iframe shows word application with the document opened.

I want to hide the ribbon that's inside the iframe. How can i do that?
I it was a regular ActiveX control on the page, I could have written a script that hides the ribbon. but it's not, is it?
Can I write a script that interacts with the word application that's inside the iframe? is that a regular activeX inside that iframe?

Thanks,
Itay.
