how to get embedded flash movie to communicate with .net winforms app

Hi I've used the shockwave flash com object to embed my 开发者_如何学Cflash file. I have buttons you can click on within the flash movie. Is it possible to get flash to notify my winform app which button has been pressed. It's developed using actionscript3. I'm using the latest vb.Net.

You can either use FSCommand, or use ExternalInterface. The later is better, although it may be harder to understand at first because of the format it uses, although if you've already solved the CallFunction (or SendFunction?) method argument, it's the same.

There are documentation and a sample C# project in Adobe's site, but I don't know the exact URL.

EDIT: To catch FSCommand and ExternalInterface calls there are two events you can subscribe to.

Also, you could also use sockets (either binary or XML).

That's a very open question as there would be many ways to do this depending on how your website and winforms applications are setup.

My initial suggestion would be to have your flash movie call some client side javascript on the button clicks. The javascript could post to a .Net SOAP webservice for instance which logs the button interaction to an associated database. Then your winforms application could finally check the database for the presence of new button click records.

This is just one high level suggestion based on the very high level question asked. If there's more specific information available then this can be refined.

Brian.
