elements Error-handling strategies Since many applications can run without building the logic to handle errors, developers are tempted to postpone building error handling into their applications. However, without error handling, an application as3 error 1009 can easily stall or frustrate the user if something doesn’t work as expected. as3 error 1010 ActionScript 2.0 has an Error class that allows you to build logic into custom functions to throw an exception with

a specific message. Because error handling is critical for making a user-friendly application, ActionScript 3.0 includes an expanded architecture for catching errors. Note: While the ActionScript 3.0 Reference for the Adobe Flash Platform
As3 Error 1119
documents the exceptions thrown by many methods, it might not include all possible exceptions for each method. A method might throw an exception for syntax errors or other problems that are not noted explicitly in the method description, even when the description does list some of the exceptions a method throws. ActionScript 3.0 error-handling elements ActionScript 3.0 includes many tools for error handling, including: Error classes. ActionScript as3 error 1120 3.0 includes a broad range of Error classes to expand the scope of situations that can produce error objects. Each Error class helps applications handle and respond to specific error conditions, whether they are related to system errors (like a MemoryError condition), coding errors (like an ArgumentError condition), networking and communication errors (like a URIError condition), or other situations. For more information on each class, see Comparing the Error classes. Fewer silent failures. In earlier versions of Flash Player, errors were generated and reported only if you explicitly used the throw statement. For Flash Player 9 and later Flash runtimes, native ActionScript methods and properties throw run-time errors. These errors allow you to handle these exceptions more effectively when they occur, then react to each exception, individually. Clear error messages displayed during debugging. When you are using the debugger version of a Flash runtime, problematic code or situations generate robust error messages, which help you easily identify reasons why a particular block of code fails. These messages make fixing errors more efficient. For more information, see Working with the debugger versions of Flash runtimes. Precise errors allow for clear error messages displayed to users.

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.

You can find more information here: flash.events.UncaughtErrorEvents This can be especially helpful for handling exceptions from a loaded SWF. I assume you have a good reason for doing this? share|improve this answer edited Oct 6 '11 at 6:45 answered Oct 6 '11 at 6:40 Peter 2,6131225 thanks!

crashes for users is because of Flash, hence the new plug-in sequestering (i.e. if Flash blows up real good, it'll do so in a way that won't negatively affect the browser). I agree. If you've ever surfed the web using the debug Flash Player, Safari 3 and 4 explode all the time. I don't know the true cause, but I do know when it'll happen most often: when you get an error dialogue. These are shown only if you have the debug Flash Player installed, and an error that wasn't "caught" happens. Sometimes hitting the "Continue" button vs. the "Dismiss All" button will work… but not always… BOOM! Â Thank God for History > Reopen All Windows from Last Session. Â Here's how you can help prevent Flash's bad name from getting worse (that and until Adobe makes it more stable). Introduction I've written about errors in the past, but wanted to write a more recent, basic, and thorough example since now more than ever, I'm seeing errors all over the web with Flash content nowadays. Flash Player 9 and 10 have errors. Â These are like Java's unchecked exceptions. Â There are 2 types of errors: synchronous and asynchronous meaning "immediately happening while your code is running" and "sometime later when our code is chilling". Â Errors occur when your code does something it's not allowed, or can't, do. Â In the past, you couldn't catch these errors nor attempt to recover from them. Â Try/catch did exist in a primitive form in AS2/AS1 but didn't cover all conditions, and sometimes if used would abort entire blocks of code without you knowing where. Â Errors are a feature of the new ActionScript virtual machine in Flash Player 9 and 10, and are thus really good. The best way to prevent errors from getting in your code is a good compiler. Â The Flash CS3/CS4, and the Flex SDK's mxmlc compiler do a very good job of spotting errors before they happen. Â The #1 error most of us faced in AS1 was capitalization; if you mispelled a variable, and attempte
