, System.onStatus
LocalConnection.send()
Availability
Flash Player 6.
Usage
sending_lc.send (connectionName, method [, p1,...,pN])
Parameters
connectionName
A string that corresponds to the connection name specified in the
LocalConnection.connect() command that wants to communicate with sending_lc.
method A string specifying the name of the method to be invoked in the receiving
LocalConnection object. The following method names cause the command to fail:
send,
connect, close, domain, onStatus, and allowDomain.
p1,...pN Optional parameters to be passed to the specified method.
Returns
A Boolean value of true if Flash can carry out the request, false otherwise.
Note: A return value of true does not necessarily mean that Flash successfully connected to a
receiving LocalConnection object, only that the command is syntactically correct. To determine
whether the connection succeeded, see LocalConnection.onStatus.
Description
Method; invokes the method named method on a connection opened with the
LocalConnection.connect(connectionName) command (called the “receiving
LocalConnection object”). The object used with this command is called the “sending
LocalConnection object”. The SWF files that contain the sending and receiving objects must be
running on the same client machine.
There is a limit to the amount of data you can pass as parameters to this command. If the
command returns
false but your syntax is correct, try breaking up the
LocalConnection.send() requests into multiple commands.
As discussed in the entry LocalConnection.connect(), Flash adds the current superdomain to
connectionName by default. If you are implementing communication between different
domains, you need to define connectionName in both the sending and receiving
LocalConnection objects in such a way that Flash does not add the current superdomain to
connectionName. There are two ways you can do so:
• Use an underscore (_) at the beginning of connectionName in both the sending and
receiving LocalConnection objects. In the SWF file containing the receiving object, use
LocalConnection.allowDomain to specify that connections from any domain will be
accepted. This implementation lets you store your sending and receiving SWF files in
any domain.
