Before you use this Object you HAVE TO see this:

SWF to SWF on different domains

Based on apps nature – for generic/unknown domains you can use super generic form (works for every combination domain/swf/air). Notice the underscore character “_” with connection name:

// SWF receiver on unknown domain

localConnection.allowDomain("*");

localConnection.connect("_connectionName");

// SWF sender on unknown domain

sendingLC.send("_connectionName", "methodName");

… or more secure version, where you define exactly the domain you are targeting:

// SWF receiver on domain1.com

localConnection.allowDomain("domain2.com");

localConnection.connect("connectionName");

// SWF sender on domain2.com

localConnection.send("domain1.com:connectionName", "methodName");

AIR to SWF

Now its getting tricky, please focus. Air app calls method on swf on some exact domain:

// SWF receiver on domain1.com

localConnection.allowDomain("app#SENDERAIRID"); // e.g. "app#sk.yoz.air.SenderApp"

localConnection.connect("connectionName");

// AIR sender

localConnection.send("domain1.com:connectionName", "methodName");

… or the same super generic method mentioned earlier for unknown/generic receiver swf file location

// SWF receiver on unknown domain

localConnection.allowDomain("*");

localConnection.connect("_connectionName");

// AIR sender

localConnection.send("_connectionName", "methodName");

SWF to AIR

… now the opposite standing air receiver and swf sender:

// AIR receiver

localConnection.allowDomain("domain1.com");

localConnection.connect("connectionName");

// SWF sender on domain1.com

localConnection.send("app#RECEIVERAIRID:connectionName", "methodName");

// e.g. "app#sk.yoz.air.ReceiverApp:connectionName"

… or use super generic form:

// AIR receiver

localConnection.allowDomain("domain1.com");

localConnection.connect("_connectionName");

// SWF sender on domain1.com

localConnection.send("_connectionName", "methodName");

AIR to AIR

This one is hefty, make sure to substitute with correct ids:

// AIR receiver (sk.yoz.air.ReceiverApp)

localConnection.allowDomain("app#SENDERAIRID"); // e.g. "app#sk.yoz.air.SenderApp"

localConnection.allowDomain("localhost"); // may help with local testing

localConnection.connect("connectionName");

// AIR sender (sk.yoz.air.SenderApp)

localConnection.send("app#RECEIVERAIRID:connectionName", "methodName");

// e.g. "app#sk.yoz.air.ReceiverApp:connectionName"

… or once again the generic form, now possible even without allowDomain()

// AIR receiver

localConnection.connect("_connectionName");

// AIR sender

localConnection.send("_connectionName", "methodName");
