ActionScript 3.0 :: Flash General Error And Exception Handling Function?
Jun 8, 2010Is there a way to handle errors and exceptions in AS3 as one would do so using `set_error_handler` and `set_exception_handler` in PHP?

ActionScript 3.0 :: ZendAMF Error Handling - Make The PHP File Throw An Exception That Gets Traced As An Error Message
Jul 7, 2010i am currently trying to learn ZendAMF, but i have a hard time troubleshooting which makes learning it quite hard. Is there a way to make the PHP file throw an exception that gets traced as an error message in AS3 (not Flex), the only error i seem to be able to get is "Error #2044: Unhandled NetStatusEvent:. level=error, code=NetConnection.Call.Failed", but it tells me jack ****.
i have gotten ZendAMF working, i just want to know how i can make error handling better, so that as an example can use PHP to tell flash that no results were found, or that the typed text was invalid. Is it better to use AS3 to check if the field was filled properly?
ActionScript 3.0 :: Range Exception Handling?
Sep 3, 2011Code:
for (i=1; i<9; i++) {
if (this["blank"+i].getChildAt(0) is Letters) {
word += this["blank"+i].getChildAt(0).letter;
}
}
This code throws a range exception if, for instance, "blank2" doesn't contain any children.I just need to be able to basically say, "if this blank doesn't have any children, just skip this code."Normally I would do something along the lines of an if=null statement, but this won't work here because
Code:
if (this["blank"+i.getChildAt(0) != null)
obviously throws the same range exception.How do you deal with this? I can't find anything along the lines of a "does blank1 contain any children" sort of method.R
Flash :: Cross-domain Error - Uncaught Exception: Error Calling Method On NPObject ?
Oct 28, 2009I am trying to emulate (in a limited way) the behavior of JavaScript's XMLHttpRequest object through Flash/ActionScript 3, in order to overcome the same-domain limitation. But I'm discovering that ActionScript has its own limitations in that regard. I admit that I might be mistaken, but from what I understand it is theoretically still possible to do this sort of cross-domain scripting using ActionScript, so long as you get all the permissions right. And that's where I'm running into trouble.
First, I borrowed some open-source code for a class called AjaxRequest, which I have saved as /ajax/AjaxRequest.as. I then created a Flash file called /jsajax.fla which exports to the final SWF file, /jsajax.swf. Now, here's the ActionScript code that comprises the first and only frame of the Flash file:
import ajax.AjaxRequest;
Security.allowDomain("domainone.com");
Security.allowDomain("domaintwo.com");[code]....
This is the only case I could not get working, and this is the case I need to get working. The first two were really just test scenarios to see if the script was working at all. When I try to run my jsAjax function here, I wind up with an error that shows up twice in Firebug:
uncaught exception: Error calling method on NPObject! [plugin exception: Error in Actionscript. Use a try/catch block to find error.].

Uncaught Exception: Error In Actionscript. Use A Try/catch Block To Find Error?
May 3, 2010I'm calling a function in my actionscript called GrabWidget() from the javascript. When I do this from a plain page with just the flash and the javascript link, everything works flawlessly. However, when I add this to a page, I get the error: uncaught exception: Error in Actionscript. Use a try/catch block to find error.I've even gone so far as to empty out the contents of GrabWidget() in my actionscript and I still get the error.

For example, my web service has a function to insert employee into db.Suppose while inserting the data , the database gave an error,what should be the best way to inform the user about the error.
One way is to depict it through the return value of the web service method but what to do when the function is supposed to return a complex object like employee when there is no error ,and will send an error string when there is an error ?

ActionScript 2.0 :: Handling URL Loader Error Event
Dec 6, 2006There is a file (php script) stored remotely on the server and I want to read it into flash using AS3.0's URLLoader. 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 didn't 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);
[Code] .....
This code traces tons of data, when executed with internet connection up:
Code:
openHandler: [Event type="open" bubbles=false cancelable=false eventPhase=2]
progressHandler loaded:10 total: 30
httpStatusHandler: [HTTPStatusEvent type="httpStatus" bubbles=false cancelable=false eventPhase=2 status=0]
completeHandler data: 1165428133
but it traces NOTHING (?!),
If the connection is down (whether closed by firewall, or cable-unplugged). So that basically means, none of the above events is fired, none of them takes care of the errorHandling in case of no-internet-connection (or if for some reason we can't reach the server atm). Any ErrorEvent i can use to catch such (connection down) Error Event? Or do I have to use Timer class instead to check wether the server responded in some time or not? I would like to leave this as the last option.

ActionScript 3.0 :: Function Handling Generic Vectors?
Jul 22, 2010I have this question regarding vectors. Is there a way where I can make a generic utility method which would for example, subdivide a vector into two vectors and would be able to handle all types of vectors, whether they contain <int> or <string> or <myClass>
for example:
ActionScript Code:
public function splitVectorIntoTwo(v:Vector.<T>):Vector.<Vector.<T>> {
var result:Vector.<Vector.<T>> = new Vector.<Vector.<T>>();
//Do logic
return result;
}
I don't know if this is possible but else it hinders our development quite a bit by using vectors since we can't use some generic utility methods as they will not accept generic vector types and you have to create a specific method for every vector type, one for Vector.<int> one for Vector.<string> etc.... With arrays, since they are not type-safe they can be passed within every such method.
ActionScript 3.0 :: Annoying Handling Of Function Pointers
Oct 31, 2010I'm not sure if you've noticed this, probably not, but function pointers in AS3 run much, much slower than calling the function directly. It's a recent finding, and an annoying one. I use function pointers a lot. An obvious example would be to easily change the behaviour of a certain object. Say I have a class that controls movement, it has a class level function variable called UPDATE (ie public var UPDATE:Function), and 3 or 4 actual functions it can point to.
This always me to quickly/easily change the behaviour of an object. Say for example I want an object to run on different movement code once it's collided with something, I can just do UPDATE = movement2; etc. However, a pointer for a function runs about 15 times slower than running the function directly, therefore I need a replacement. And I really have no idea why there is this absurd disparity in speed between the 2. With some variables, accessing a reference is faster than accessing the variable directly, obviously not with functions. What would you advise as a nice, simple replacement solution for the above example?

ActionScript 3.0 :: General Flash Security: Validating Events Online?
Jun 16, 2010Given the nearly plain-text nature of Flash, from a security standpoint, we must assume that your SWF can be decompiled into human readable format. That said, how can we ensure the validity of any online calls? For example, recording a high score might make a call similar to this:
Code:
var url:String = "http://someserver.com/tracker/scoreTable.aspx?mode=record&score=" + _userScore + "&checksum=" + MD5.hash( /* stuff */);
var loader:URLLoader = new URLLoader( );
loader.load( new URLRequest( url ) );
You can do all the MD5 hash checking to make sure the data received matches what was sent, but how can you verify the validity of the call? For instance, one could decompile the SWF and figure out how to build the query string manually, or they could reverse engineer it from monitoring the internet calls from the SWF itself. They could even use a run-time memory editor to change the figures that store the information while playing the game, so that when the recordHighScore call is made, it sends 1,000,000 instead of 1,000. How does one authoritatively validate data and protect against abuse?
Media Server :: FMS 3.5 Says 'Bad Network Data': Error In Handling RTMP Extended Timestamps / ChunkSize?
Jun 3, 2011For a client, I am working on a project where a live RTMP stream is published to an Adobe FMS 3.5.6 server from a java application, using Red5 0.9.1 RTMPClient code. This works fine, until the timestamp becomes higher than 0xFFFFFF after 4.6 hours, and the RTMP extended timestamp field starts being used. I have already found: when the extended timestamp was written after the header, the last 4 bytes of the data were being cut off. I have fixed this locally, and now the data being sent seems to me to be conformant to the spec. However, FMS still throws an error message in the core log and then kills the connection from the Red5 client. Here is the error message:

I did some research and found out that the problem probably lies in the fact that the flash runtime cannot handle http responses with status code other than 200.

View 1 RepliesProfessional :: General Feedback For Adobe
Nov 20, 2011I'm sorry if this is the wrong place to post this, but I looked for a place to send general "feedback" and could not find one.I just wanted to let the management at Adobe know a couple things related to recent Public Relations blunders. Ever since the announcment that you were ending Flash Player for Mobile, I have had many conversations with people about this topic and there is SO much misinformation due to your announcement, it's going to tank Flash as a broader platform.
- Some think Flash doesn't work on Macs
- Some think the Flash player is cancelled on ALL platforms (PC included)
- Some think Flash in its entirety is coming to an end.
This perception seems to come from people of various levels of technical knowledge, from basic users where it's understandable they might be confused about the specifics of the recent news (but still not a good thing!) on up to key decision makers who don't know tech but are key to making certain spending decisions with regard to tech platforms (CEOs). This is a horrible place for Flash to be in right now and you need to quickly change the perception with a "Flash is alive and well" type of announcement.Remember, most people only retain sound bites and a few words from headlines. You may have announced "Adobe ends Flash Player for Mobile" originally, but what people retained was "Adobe ends Flash Player". You need to make a new announcement that the short attention span people will come away from with knowledge that all is well. "Flash not dead" for example.Man, whoever plans your PR needs to be fired. You could have killed off the Mobile player back before the MAX conference and then followed up with the news about Flash Player 11 and Stage 3D. That would have a perfect one-two punch, but instead you reversed it and all the excitement from FP11 @ MAX was blown away.
