That looks about the right amount of code to me. Someday, I expect AIR to make this easier, but I wouldn't hold my breath waiting.

Hi Alex! Good to hear from you. And yes, you're right! I got it to work but there's so much code involved just to get this module loaded. Gosh...I wonder if I am in the right direction or not... This code is basically based on "Hai Nguyen" example from eSoftHead with little modification (Thx Hai!). Here's the code if anyone is interested: <mx:WindowedApplication> <mx:Script> private function loadSwf():void { var dir:File = File.applicationStorageDirectory dir = dir.resolvePath("SimpleSwf.swf");//SimpleSwf is the module var myURLRequest:URLRequest = new URLRequest(dir.url); var myURLLoader:URLLoader = new URLLoader(); myURLLoader.dataFormat = URLLoaderDataFormat.BINARY; myURLLoader.load(myURLRequest); myURLLoader.addEventListener(Event.COMPLETE,loadModuleCompleteHandler); } private function loadModuleCompleteHandler(pEvent:Event):void { var context:LoaderContext = new LoaderContext(); context.allowLoadBytesCodeExecution = true; context.applicationDomain = ApplicationDomain.currentDomain; var moduleLoader:Loader = new Loader(); var loader:URLLoader = URLLoader(pEvent.target); moduleLoader.loadBytes(loader.data,context); moduleLoader.contentLoaderInfo.addEventListener(Event.COMPLETE, completeLoader); } private function completeLoader(e:Event): void { var moduleLoader:LoaderInfo = LoaderInfo(e.target); moduleLoader.content.addEventListener("ready", readyHandler); } private function readyHandler(e:Event): void { var factory:IFlexModuleFactory = IFlexModuleFactory(e.target); var module:Module = factory.create() as Module; container.addChild(module); } </mx:Script> <mx:VBox width="100%" height="100%"> <mx:Button label="Load SWF" click="loadSwf()"/> <mx:VBox id="container"/> </mx:VBox> </mx:WindowedApplication> --- In flexcoders@yahoogroups.com<mailto:flexcoders%40yahoogroups.com>, Alex Harui <aha...@...> wrote: > > I'm not sure what moduleLoader is.
