Hi Dick, I've tried to get the applet, but the NYSE, AMEX and OPRA form agreement is only for US people (only US in the select...) and I prefer not to create a "fake" account.
The problem is that I have no idea how they get the data from the java applet.. Is it through a socket connection (real-time)? From which server? Or is it through a scheduled http call (to a web services?), for example every 10s. (nearly real-time)? It is pretty important to know from where you'll get those real-time data. You can do real time data with FlashMX by using the following ActionScript object: - XMLSocket(), you'll need a socket server (http://www.moock.org/unity/), XML text format messages, - NetConnection(), you'll need FlashCom server, AMF binary format messages (much better for the client and the bandwith). But to create a "nearly" real-time app is much easier to develop... You can easily go from static to "nearly" real-time. No need for a socket server, a simple application server is required (CFMX for example), the flash client could get data from the server through URL variables, XML data (web services) or flash remoting (prefered method especially if you have CFMX). In ActionScript on the client, you'll just have to create a function/method that get the data from the app server and then create a setInterval() to call this method every x secondes. Anyway, I'm afraid to be too OT for CF-Talk on this thread... You might try to post the question on a flash mailing list such as http://chattyfig.figleaf.com/ Good luck!
