I have a large xml passed from grails to flex. When flex receives the xml, it converts the xml into an associative array object. Given the large xml file, it takes too long to complete the loop, is there any way in flex to make conversion faster? Below is my sample code.

this seems really simple but I haven't gotten this to work. I am building my app with grails on google app engine. This pretty much requires you to use JDO. I am making an HTTP call from flex to my app. The action that I am calling on the grails end looks like so
[Code]...
I have tried just returning "hello from grails" and that works just fine. I have alos tried the following return showInstanceList the JDO docs say the query.execute() returns a collection. Why I cant just return that to Flex I have no clue. after playing around with this some more I was able to get a result event back by have grails convert the object to JSON or XML wish I could just return a damn ArrayList.
where should I put the crossdomain.xml to my grails app? I need to use webservices from external domains in my flex client app. I put it into my web-app folder but it seems not working..
View 3 RepliesI'm writing an application, Flex front-end & Grails back-end, in which I need to integrate security. All the information around Grails gives me the impression to be well suited for when your client is written in HTML but how can I use Flex's HTTPService to integrate into it?

I have a grails application that will be rendering an html page into a pdf file and I have a flex application sitting on a server that is going to accept REST parameters and construct a graph based on the parameters (which will be formatted in JSON). What I want to do is make a call to the flex app with my parameters and have the flex app create the graph, render a JPEG of the graph, then send an image back to grails. In other words, I want to put an HTML img src=that will render the image directly to the page so that my PDF Plugin in grails will render it into the PDF.

My question is, does a better, faster CPU necessarily equal faster SWF compile times? Or does it rely on something else (OS, memory, etc). I only use AS3 and some of my projects take a while to compile. If certain hardware can guarantee me a faster compile time, it'd be worth including those things in my shopping list.

View 1 RepliesI'm wondering which is faster in AS3:
array.forEach( function(v:Object, ...args):void
{ ... } );
Or
var l:int = array.length;
for ( var i:int = 0; i < l; i++ ) { ... }
I need to know the best method to find an item inside a list (Vector, Array, Dictionary, whatever is faster) of complex type (extensions of Objects and Sprites).I've used "Needle in Haystack" method, but it seems that it isn't fast enough.
E.g.Suppose that I have a collection of Sprites (a pool, in fact).Each sprite will be added to the stage and perform some action. After that, it will die.I don't want to pay the cost to dispose it (garbage collect) and create another (new) one every time so I'll keep the dead sprites in a collection.
Sometimes times I'll call a method that will add a sprite to the stage.This sprite can be a old one, if it is already dead, or a new one, if the pool don't have any free sprite.
One of the scenarios that pushed me to this question was a Particle System.A "head" particle leaving a "trail" of particles every frame and exploding into a flashy multitude of particles... Every frame...Some times this counts up to 50.000 PNGs with motion, rotation, alpha, event dispatching, scale, etc...But, this is JUST ONE scenario...At the moment I'm trying to use a Object Pool with a Linked List...Hopes that it will be faster that running a whole Array/Vector or create new instances every frame an let them dye with Garbage Collection.
[code]in my original code..function "test" will change the x axis of the images by Timer..I wanna the x axis of the images can be changed after every two seconds..but when I run it..it's obvies faster and faster every time when the Timer dispatch the TimeEvent the delay always shorter than the last time.

View 3 RepliesI made a Flex 4 web application. Upon testing locally, I already got satisfied at how it looks like. However, the swf's file size grew to around 6mb in size so when I uploaded it to my website and viewed it, it takes forever to load on a computer with quite slow internet connection. So my question is, how do I make it load faster? Should I:
separate it into chunks? If so how do I do it.
not put the embedded images inside the SWF but instead, store it outside in a folder? If so, how do I make it load on the background while the user is interacting with the primarily loaded parts of the web app?
I have a C++ application which sends images to a Flex/Air front-end via TCP sockets. All this data transfer occur in the same host, so the socket connects to a localhost server. The problem is that the Flex/Air takes a really long time to read the entire image from the socket. The server sends the image quite fast, but the Flex/Air reads this image in tiny parts. The whole image has about 300MB and the Flex/AIR reads only about 1KB each iteration. So the flex keeps calling the socket data callback, which is causing the application to slowdown.
Is there any synchronous sockets to use with flex, or some kind of socket which can read the entire data all at once? If sockets aren't the best choice, is there any other faster options? My socket class looks like this:
[Code]...
So is
public var user:Object = {};
user["firstName"] = "Bill";
user["lastName"] = "Cosby";
Slower than if I have a value object like User?
var user:User = new User();
user.firstName = "Bill";
user.lastName = "Cosby";
We are in process of optimization of Flex AS3 Application.
One of my team member suggested us to make varible name length smaller to optimize the application performence.
i.e.var IsRegionSelected:Boolean = false; //Slower
var IsRS:Boolean = false; //faster

View 1 RepliesI have seen a few blog entries on this and have had a discussion or two with my team mates but I would like to see what the stack overflow community thinks.
So why does the Adobe Alchemy Tool create so much faster running flash byte code than the flex compiler?
Also, when will the flex compiler be able to make similar performance gains? Will it require programmer specific use of special Array's or something of that nature to get the same performance?
I want to change the value of a variable listed in an array using the array. for example:
Code:
var theVariable:Number = 15;
var theArray:Array = [theVariable];
now if I try this
Code:
theArray[0] = 20;
I just get an array with 1 value of 20 in it and it no longer references theVariable what i want to do is change the value of theVariable with out removing it from the array but referencing it from the array in a loop or something.
I have a grails application using jquery mobile. I am hoping to find some way to access the camera on the devices. I thought about using flash to grab the webcam but that obviously wont work on Apple devices. Does anyone know of a way to do it and keep it all browser based?

View 1 RepliesI am displaying a combo box in something of a WYSIWYG preview. I want the user to be able to click on the combo box and see the options inside, but I don't want them to be able to change the value. I tried using preventDefault() on the change event but it doesn't work. I don't want to disable it because I do want the user to be able to "look inside" the dropdown.
So I'm trying to block the change, but can't. My next resort is to change the selected index back to what it was before the change, Is there any way to do this within the scope of a ListEvent.CHANGE event listener?
Current Workaround is to basically re-assign the controls selected item the same way I am defining the selected item when I originally build it (a default selection). So a user sees their change then it immediately changes back to the default selection.
We're writing a flash application that can download a MP3 file, convert it to a Sound object, get the raw data and make some processing (like adding sounds, change octaves). After the processing, we want to send the data back to the server in chunks, so the server will be able to glue the data together and recover the new generated file. The problem is: if we send to the server "wav" pieces of sound, we are able to glue them together without any problem in the generated file. However, if we convert each wav piece to a mp3 file (so we can send a smaller file to the server) and join the mp3 files at the server, the result is a sound with some problems at the merge point.
This is how we load the mp3 file from the server:
sourceSnd.load(new URLRequest("sample url to mp3"));
sourceSnd.addEventListener(Event.COMPLETE, carregou);
This is how we convert each piece of mp3 to bytearray and wav:

I am making a flash game and I am trying to make it as efficient as possible. I need to set a timer and then do something after the timer runs out.So, that being said I am wondering which method would be faster (or more efficient):Making a timer object and listening to the TimerEvent.TIMER_COMPLETE or in the ENTER_FRAME event of the game checking a Boolean (time) and then if it is true, incrementing a variable until that variable is equal to x, then performing the operations.
