Hi John,

We are using the Microsoft IE browser and is the only browser we will be supporting for the time being.

Correct we are looking at ways to communicate between PDF, HTML and SWF's. To start of with, I'd like to know how it is possible to allow PDF actions to communicate with the html page, so ajax type calls can be made?

Maybe you could point me in the direction on some further documentation on this?

Cheers
Gareth.

Just to check, we're talking about using the variety of WWW browsers
your audience may have, and putting in SWF and PDF elements in the same
HTML page, and having them all intercommunicate... is that the goal?

If so, I know that there was LiveConnect support in past versions of
Acrobat Reader, but I don't know offhand if the current Adobe Reader
7.0x has yet implemented the NPRuntime communication spec in recent
browsers.

(Background: Netscape/Mozilla have had three different
intercommunication schemes, with the most recent one also adopted by
Opera and Safari... Microsoft's Windows browsers have had a parallel
scheme... in plugins these differing approaches have generally been
papered-over with "externalEvent" or "FSCommand" or "ExternalInterface"
types of calls. In addition to these browser-provided intercommunication
methods people have hacked around browsers for years, whether through
"_javascript_:" pseudo-URLs or refreshing a small DIV or whatever. Lots of
  browser difference here.)

A lot would depend on which browsers your audience uses (brand, version
and platform), and which ways you need communication to flow. That's the
base restriction.

The Apollo project will focus on making it easier for HTML, SWF and PDF
to intercommunicate with a minimum of hassle, but right now you've got
to lock down the biggest variable, and that's the browsers your audience
has chosen. After that you can research communication methods those
browsers support. Not an easy answer, I'm afraid. :(
