while an application is running. This type of error handling lets your application notice and recover as3 error class from run-time errors when functions fail. The logic for catching a synchronous error includes try..catch..finally statements, which literally try an operation, catch any error response from the Flash

runtime, and finally execute some other operation to handle the failed operation. Using try..catch..finally statements When you work with synchronous run-time errors, use the try..catch..finally statements to catch errors. When a run-time error occurs, the Flash runtime throws an exception, which means that it suspends normal execution and creates a special object of type Error. as3 try catch finally The Error object is then thrown to the first available catch block. The try statement encloses statements that have the potential to create errors. You always use the catch statement with a try statement. If an error is detected in one of the statements in the try statement block, the catch statements that are attached to that try statement run. The finally statement encloses statements that run whether an error occurs in the try block. If there is no error, the statements within the finally block execute after the try block statements complete. If there is an error, the appropriate catch statement executes first, followed by the statements in the finally block. The following code demonstrates the syntax for using the try..catch..finally statements: try { // some code that could throw an error } catch (err:Error) { // code to react to the error } finally { // Code that runs whether an error was thrown. This code can clean // up a

The Error class contains information about an error that occurred in a script. In developing ActionScript 3.0 applications, when you run your compiled code in the debugger version of a Flash runtime, a dialog box displays exceptions of type Error, or of a subclass, to help you troubleshoot the code. You create an Error object by using the Error constructor function. Typically, you throw a new Error object from within a try code block that is caught by a catch code block. You can also create a subclass of the Error class and throw instances of that subclass.

For example, I have a lot of functions in myClass.as. I don't wanna write in each function try catch blocks in order to catch flash as3 error errors in this function. Is there any methods to do this?

The best practice is just let you classes bubble the Error (Exception) and let the higher layer catch and process the error. EDIT - regarding coment Actually the idea is the natural way.. still you need to manually catch every possible error. i'll give you example. Note that the purpose of the example only for clarity between lower layer and higher layer. for example you have a class in the mid layer (Your Business Process): public class MyBussiness { public function loadImages(){ //for example here is a block of method //possibly throws exception. } public function getLoan(){ //lets assume here too } } in the higer layer (I Assume in your View - MXML) you catch the exception like bell

However, if i unplug my cable just before reading the file, and attempt to read the file, i want to capture an Error event in some error handler, which would mean "internet connection is down, file can not be accessed". I am reading the AS3.0 documentation now for 2 hours already (mainly: "Handling asynchronous errors in an application" and "Events of URLLoader class"), but i didnt stumble across an example of how to catch an Error event of the URLLoader object when reading a remote file from the server. However i took all possible events i could find (even those which are not necessary at all), and tested them in the following code: Code: public function URLLoaderTest( ) { _loader = new URLLoader( ); // _loader is private var of this class configureListeners(_loader); var request:URLRequest = new URLRequest("url_with_php_script"); _loader.load(request); } // LISTENERS private function configureListeners(dispatcher:IEventDispatcher):void { dispatcher.addEventListener(Event.COMPLETE, completeHandler); dispatcher.addEventListener(Event.OPEN, openHandler); dispatcher.addEventListener(ErrorEvent.ERROR, onError) dispatcher.addEventListener(AsyncErrorEvent.ASYNC_ERROR, onAsyncError); dispatcher.addEventListener(NetStatusEvent.NET_STATUS, onNetStatus); dispatcher.addEventListener(ProgressEvent.PROGRESS, progressHandler); dispatcher.ad
