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.
