Could you pass the variables through the url that you load? Like:
htpp://www.somewhere.com/someflashthing.swf?avar=this&bvar=that Flash receives those and do whatever it's supposed to do. _______________________________________________ use-revolution mailing list use-revolution@...

Early versions (MX MX2004) could read files, send and receive packets from servers, and listen for packets from servers (variable strings or XML format) using GET or POST methods. You should be able to save the XML file using any app, including Rev, as long as the permissions are correct. The Flash movie should be able to read that file.

Interesting idea. But I think you'll have to overcome Flash's security restrictions. If the Flash file is loaded from the web, by default it can't connect to any other domain, including the local domain. However, there is a way to get round this by using a cross-domain policy file. I've never tried this for XMLSocket(), but according to the docs it's doable. However, it's not clear whether that can be used for connections to localhost instead of other domains on the internet. Worth trying. There's some information here about implementing a socket policy file. http://livedocs.adobe.com/flex/2/docs/wwhelp/wwhimpl/common/html/wwhelp.htm?context=LiveDocs_Parts&file=00001952.html > > > 2. A local socket, is that something like "127.0.0.0: port number"? I think "localhost:portnum" will work. Please let us know if you have any success.

No. Though I can't say whether or not highly restrictive local firewalls, or anti-virus software may cause conflict, though I've done this process on my systems, and it has worked fine. > > > 4.

I don't see why that should matter, since you aren't actually even actually leaving the local system, and the IP is strictly local to the machine. > > > 5.

Sure, but the name is misleading, it is actually just a standard text connection. In the end, it works like this... you have Rev start listening for a socket connection, you have Flash connect to it, and you start communicating back and forth. -- Troy RPSystems, Ltd. http://www.rpsystems.net _______________________________________________ use-revolution mailing list use-revolution@...

You can try this in the Rev message box. go url "http://www.lacscentre.co.uk/flex/socketTest/FlashSocketTest.rev" When the stack loads, click the Setup button. It will load a swf file using revBrowser. When the swf file has loaded, click its "Get Environment From Rev" button. Hopefully, it will display the environment variables and time supplied by Rev.

I had trouble working out how to manage the connection from the Rev side. If you want Rev to push data to the Flash element at arbitrary times, you need to keep the connection open. But if you also want to accept data from the Flash element, doesn't the Flash script need to reset the connection prior to sending data otherwise Rev doesn't know when to read from the socket. In the example above, Rev closes the socket each time after sending the data, forcing the Flash component to reconnect. Is there a cleaner approach to this?

I believe that when I've done this in the past, I've just polled the socket for data. -- Troy RPSystems, Ltd. http://www.rpsystems.net _______________________________________________ use-revolution mailing list use-revolution@...
