you need register ioerror function event handler on loaderinfo object. assume somewhere you've created loader load external swf. here's example adobe (http://www.adobe.com/livedocs/flash/9.0/actionscriptlangrefv3/flash/display/loaderinfo.html) edited remove classes.

import flash.display.loader; import flash.display.loaderinfo; import flash.display.sprite; import flash.events.*; import flash.net.urlrequest;  var loader:loader = new loader(); loader.contentloaderinfo.addeventlistener(ioerrorevent.io_error, ioerrorhandler); var request:urlrequest = new urlrequest("some.swf"); loader.load(request); addchild(loader);  function ioerrorhandler(event:ioerrorevent):void {      trace("ioerrorhandler: " + event); }
