LocalConnection (object)

Availability

	Flash Player 6.
	Flash Communication Server MX (not required).

The LocalConnection object lets you develop Flash movies that can send instructions to each other without the use of FSCommand or JavaScript. LocalConnection objects can communicate only between movies that are running on the same client machine, but they can be running in two different applications—for example, a Flash movie running in a browser and a Flash movie running in a projector. You can use LocalConnection objects to send and receive within a single movie, but this is not a standard implementation; all the examples in this section illustrate communication between different movies.

The primary methods used to send and receive data are LocalConnection.send and LocalConnection.connect. At its most basic, your code will implement the following commands; note that both the LocalConnection.send and LocalConnection.connect commands specify the same connection name, lc_name:

// Code in the receiving movie
receivingLC = new LocalConnection();
receivingLC.methodToExecute = function(param1, param2) 
{ 
	// Code to be executed
}
receivingLC.connect("lc_name");

// Code in the sending movie
sendingLC = new LocalConnection();
sendingLC.send("lc_name", "methodToExecute", dataItem1, dataItem2)

The simplest way to use the LocalConnection object is to allow communication only between LocalConnection objects located in the same domain, since you won't have to address issues related to security. However, if you need to allow communication between domains, you have a number of ways to implement security measures. For more information, see the discussion of the connectionName parameter in LocalConnection.send, and also the LocalConnection.allowDomain and LocalConnection.domain entries.
