I have a flex application that repeatedly polls a remote XML file to detect changes, but I've found that once the file hits a certain size, the poll blocks the UI and makes the page unresponsive for a short time.
Is there any way to ensure that the call made to the server or the event from the flash.utils.Timer class runs asynchronously to the main UI thread?
I've been using Flash for a while now but have just started using Flash Combined with XML. I'm trying to make a poll system in flash which grabs data from a PHP generated xml file. This is the contents of the xml file at the moment.

I have a flex application that shows information gathered from different external services by using rest api. Some of them are resource intensive, take longer to response.
View 1 RepliesI'd like to tell if a certain key is being held down around the startup of my AIR (desktop) application, and I'd like to tell if a specific key (ALT in this case) is being held down. Unfortunately, flex seems to be so event based that there is no way poll the keyboard directly. Can anyone verify this?
I know that it's possible to take the keyboard events and keep track manually. However, this won't work if the user presses the key right before startup, so it isn't a solution for my specific problem.
I'm working on implementing communication between an Adobe AIR app and a browser Flash object, and the LocalConnection documentation mentions an asyncError as a potential event:
asyncError: Dispatched when an exception is thrown asynchronously — that is, from native asynchronous code.
However, that's the only documentation I can find on it. Does anyone know what this error actually means? I've searched around but couldn't find any reference -- most sample code I found does an addEventListener() for the asyncError but doesn't give any clue as to what it means or when it could occur (i.e. if it could occur when sending or when recieving).The Adobe documentation page also lists potential events for each method, but asyncError isn't listed under any specific method, only for the general class.
I am adding data inside a VGroup dynamically using Action Script. Each data is an instance of a custom component. So when the number of item is more, It take time to load, which look bad.
Is there any way, we can load data to it, asynchronously or is there any way, so that more data can be added inside a scroller only when the scroll bar reaches to the end ( as it happens in Android or IPhone).?
I'm starting a project that will build a flash file with quite complex capabilities. I expect the size of the swf/swc files will be quite big. In order not to slow down the page download, can I build the swf file so only immediately needed components are loaded with the page and other later-stage components can be silently loaded in the background?
View 1 RepliesI have a Flash application that exchanges data with php scripts. Problem is, I can SEND updates, not receive.Example:
- user drags an object to another area
- flash sends this action to a php script using URLLoader
- the server acknowledges the action and returns an "ok" message with the same URLLoader
Now if the server wants to send a message, like "there's an update available", or "your friend has logged in", how is this supposed to happen?I believe an always-open socket is out of question, because the server will have to handle too many users at once and the section might be indefinitely long. I'm not so sure about the Flash client constantly pinging the server.So, what's the best way to send data from PHP to Flash asynchronously?
I am currently looking for a tutorial that will explain how to build a flash poll. This is for a website I�m working on. However, the server is not PHP friendly. Thus, I am looking for a Flash poll ASP tutorial.

View 2 RepliesI'm attempting to connect to an existing Comet-style long-poll service using an AIR app. The service expects a client to make a GET request with a Connection: Keep-Alive header. This request will remain open for long periods of time so that the server can push data through. In my app, the connection is terminated with an IOError after 30 seconds.
Is this an undocumented limitation of URLStream? A restriction on adl (I've only been running my app through adl)?
The server does not send any "keep-alive" messages to the client but, unfortunately this is not something i have control over.
Update
To test this, I've set up a stripped-down version using a little php script (linked by leggetter below) and am hitting it from a simple AIR app. I'm finding that my connections are closed after 30 seconds whether I use URLStream or URLLoader. the PHP:
<?php
set_time_limit(0);
sleep(40);
[Code]....
If i adjust the initial sleep time in the php script to anything over 30 seconds, the IOError event is triggered. If I lower the sleep time, but the request continues adding data past 30 seconds, the onComplete event is called, but _urlLoader.data is empty.
The only way this process completely successfully is if the entire thing is over before 30 seconds elapses.

View 5 RepliesI have made an application which loads large pictures and videos (1920*1080 px).
- Picture component is a swf movie that I load with a Loader and feed him with the path of the picture I need
- Video component is a custom actionscript class that uses Video class.
Before to create any of these components, I display an animated sprite (a wheel to suggest a current loading). Then I create this component and load the content. When the content is loaded, then I add it to the display list and remove the wheel sprite.As these actions take a while, the wheel is visible for 1 to 2 seconds. My problem is that during this loading operation (by a Loader or Instantiation), the animated Sprite is not running properly and smoothly, like if Flash was loading the pictures and videos synchronously.Is there a way to make an animated sprite running properly while I am loading a swf or loading a video through the instantiation of a class, means running something asynchronously?
I am working on a very simple game in Flash. I want to make all the animations framerate agnostic, so that I can change the framerate without affecting the flow and speed of the game.I read somewhere that if you want to do that, you simply create a Timer object and attach an event listener to this timer.
What if I have many objects that have to listen to the same timer? See the code to understand what I am trying to do. At this stage nothing breaks, but the event does not fire.Here is the Main class, the one that runs on swf execution:
public class Main extends MovieClip {
private static var _stage:Stage;
private static var _timer:Timer;

View 12 RepliesI have a couple of buttons that slide up and down, when in the up state I add an X graphic to symbolize a a close button. However the X graphic seems to be blocking my button action.I have an example in the movie I've been working on >> here <<.There are 2 movies here, the big one if you click either blue tab you will see what I'm talking about, X button shows up, but clicking over the X area will not drop the button down. You have to click on blue button area to drop the button back down.Now I've made a smaller test movie adding the X button basically the same way and if you will notice it works fine (will animate to the right even if you click over the X graphic)Here is my code in the Big movie (I hid the tween code so it won't be so long):
function handleButtonClick(event:MouseEvent):void {
var button:MovieClip=event.target as MovieClip;
var id:Number=Number(button.name.split("button")[1]);

I'm wondering wether there's a Javascript way to detect wether a user has any sort of flash blocking plugin installed so i can accommodate these users properly. For example, I use 'click to flash', but sites that use SiFR to render text are littered with "click to flash" buttons, which is getting very annoying. I don't use SiFR in my designs for this reason. But if I could spot wether there's a flash blocking plugin installed, I would simply not call the SiFR function.
View 1 RepliesI have a website with a flash image viewer. Once user clicks on flash button, I need to give a confirmation modal dialog before saving the file and if user clicks on OK only I have to pop file download dialog. Confirmation dialog with in flash is not an option for me. So I have to invoke JS function to pop a confirmation.Within the site, a custom DHTML confirmation modal dialog is used and it has two JS callback functions one for "OK" and the other for "Cancel" button click event handers. I have to use this modal dialog for this need.With Flash player 10 security features, it is unable to pop flash file download dialog via JavaScript
View 1 RepliesHow do you get the information bar to stop blocking the active X control for a flash movie in IE.when I am in fire fox, it just starts the flash movie. Right in the HTML page. But with IE, the info bar at the top pops up, and blocks my flash movie.Then you have to click on it, and say that you want to activate the active X on the page. Is there anyway to stop this from happening. I remember, using IE, that not all flash is blocked, just the stuff that I make.
View 7 RepliesI have decided of using AS3 on my Evaluation Quiz because only AS3 supports saving pdf file. I need this feature for reports/tracking.
The question now is where can I get Poll/Evaluation Quiz Template?
I searched for this a lot, but I couldn't find a solution for this 'bug' as it's called here:click on first flash, and use mouse wheel, then click on second flash and use mouse wheel again. Now You know perfectly what 'bug' I mean.The thing is, I believe this bug can be solved WITHOUT externalinterface. This chat is made with AS 3:pen 'codebox', hold ENTER to make a hundred of lines or so, and then test your mouse wheel.It doesn't use any externalinterface technique (both obviously as it's Kongregate, and confirmed by author), just mx.component.textArea that itself implements the scrolling nicely.I couldn't achieve that with even.preventDefault or stopPropagation.
View 1 RepliesIs it possible to delegate heavy computations to be handled asynchronously (on the user's machine)? When it's done, I could just fire an event, catch the new data, and update. I have played with this for lesser operations, by just setting up a que and only handle a few operations per frame; but is there another method? That feels like a heavy handed workaround, and it won't scale with faster/slower machines. IE: 12 operations per frame works fine on the test machine, but my machine can handle more, but won't do it because it's hard coded.
