[AS3] Resolve Error #2044: Unhandled IOErrorEvent:. text=Error #2035: URL Not Found.

While working in Flash AS3, if you get the following error:

Error #2044: Unhandled IOErrorEvent:. text=Error #2035: URL Not Found.

<img class="alignright size-full wp-image-1413" title="flash-as3" src="https://www.parorrey.com/wp-content/uploads/2011/08/flash-as3.png" alt="" width="200" height="200" />It's due to your swf/image/xml file incorrect URL and unhandled event shows the error. This error can be caught by adding eventListener to your loader object.

&nbsp;

[actionscript3]
//assuming you have loader
var yourLoader:Loader = new Loader();

yourLoader.contentLoaderInfo.addEventListener(IOErrorEvent.IO_ERROR, ioErrorHandler); 

function ioErrorHandler(event:IOErrorEvent):void 
{ 
    trace(&quot;ioErrorHandler: &quot; + event); 
} 

Hope that helps.

Cheers!
