Flex :: Make URLLoader Return An AsyncToken?
Dec 24, 2009
I was trying to retrieve binary data over HTTP for my Flex application, and was running into some stumbling blocks. HTTPService did not seem to deal with binary data well, people said to use URLLoader. But URLLoader does not have the nice AsyncToken/IResponder interface that HTTPService provides.
So, I did some searching and could not find anyone extending URLLoader to provide this kind of functionality. I went ahead and took a stab at it myself: [URL].. Basically it wraps a URLLoader and an AsyncToken, and maps the COMPLETE, IO_ERROR, and SECURITY_ERROR events from URLLoader to results/faults that get raised on the AsyncToken.

I'm trying to develop a Flex Mobile / PHP application, and I'm running into some trouble with the AsyncToken... Does it not just return a basic string?
For example... I'm wanting to just return a simple string result from my request - right now, it's going to return a basic output string from the method that's implemented. The backend part works (PHP), I've done all of that... It's this that's giving me some problems:
import mx.rpc.AsyncResponder;
import mx.rpc.events.FaultEvent;
import mx.rpc.events.ResultEvent;

Can I listen to Alert button click between components using AsyncToken?Basically, I want to have a method that opens an Alert with buttons and have it return an AsyncToken so that other components calling that method can listen for button click.
Example:
var token:AsyncToken=methodThatOpensAlert();
token.addResponder(new mx.rpc.Responder(buttonClick));

As the title suggests, why are the applyResult and applyFault methods of AsyncToken marked mx_internal?There have been a few times that I would have liked to use AsyncToken in my code, but I've ended up re-writing it because I don't want to force clients to use namespace mx_internal.

I'm developing a Flex application using RobotLegs, LiveCycle DS & Java.I'm trying to implement an update function, using LCDS, but I'm running into some strange behaviour:This is the ActionScript code within a RobotLegs' execute command, used to perform the update:
var token:AsyncToken = services.requestService.commit(new Array(model.currentRequestDetail));
responder = new AsyncResponder(resultHandler, faultHandler, token);

I'm having some troubles with the use of interface and inheritance in AS3. I've done lots of OOP in the past and what I'm trying to do seems obvious to me, but doesn't work in AS3. The question is : Is it possible to override a function that return an Object of class A, and make it return an Object of Class B which extends A ? It seems not to be possible, since I'm getting a signature error in Flash, when compiling. For example, the following set of class do not compile (the code in function definition doesn't matter):

Is there a easy / good way of getting the url from the URLLoader object? It seems at least two other people (this guy and this this guy) have wondered the same thing. Maybe we can get an answer here on s.o.?

Is there a timeout on the connection made by URLLoader.load? If there is, what's its value, where is it documented and can it be changed? Also, what event (if any) gets dispatched if the timeout occurs? Is there a difference between AIR and browser application in those regard?

how to explain this behavior but I'll try. I am loading images from an external url that requires basic auth so I am using URLLoader to load the image from a unique ID. The ID gets passed to the itemrenderer which then proceeds to load the image. But the images switch around on their own when I scroll. If I load more than 7 images or so it starts repeating images....

How do I get an array to return correctly? Doing trace(VI1.getData()[0]) doesn't work either.

I am trying to write functions as efficient and reusable as possible. One function in particular I wrote was designed to easily create new objects from externally loaded files. The problem I have is that I can't think of a way to make the function wait for an event listener to complete before returning the desired object. Here is what I have so far and I will point out where the problem is.
Code:
var myNewObj:Object = loadFile(parentName, "swfs/" , "file.swf");
function loadFile(parentObj:Object, urlLocation:String, fileName:String):Object{
var fileLoader:Loader = new Loader();

I have a flex application which is hosted on Azure.
I have some data stored in a blob in a private container.
How can I use URLLoader to display the data? If I use a public container , then I am able to read from the blob in my application. However, if the type of the container is private URLLoader fails.

My application asks the user to select files for upload using a FileReference /FileReferenceList. The client then compresses the File data and uses URLLoader to upload the contents of the file.One problem with the URLLoader is that the progress event does not get triggered for uploads. How do I track the upload progress? I am unable to create a FileReference for the newly compressed ZIP ByteArray.

I'm developing an AIR app that requires a menu to show only during the first run. In it the user will be able to choose the desired language for the app to run in.
I'm displaying this menu without a problem but I need it to stay visible until the "select language" comboBox is changed and then return the selected choice's data value.
how to return a value only after the combo box is changed.
function promptFRMenu():String{
FRMenu.enabled = FRMenu.visible = true; //when I detect the app is running for the

I'm just trying to make a simple function that will return all the data from my SQLITE database as an array. But it looks like when my function is returning the array, the SQL statement is actually still executing... so it's empty... Does anyone have a suggestion? Or am I just going about this whole thing wrong.I know I could just have the event listener functions outside this function, and they could then set the data. But i'm trying to make a AS3 Class that holds all my SQL functions, and It would be nice to have everything for this particular function just in one function, so it can return an array to me.
public function getFavsGamesArray():Array
{
getFavsArraySql.addEventListener(SQLEvent.RESULT, res);

I've been working on a mini-mouse maze in as2, placed in a movie clip called "mouse1". On frame one is the start button, and on two is the maze and finish button. So what I'm asking: is there a way to make the movieclip return to frame one when the player right clicks? I know this code, that makes it trace something but I cant use it to navigate.[code]

The idea is how i make the stars disperse and then return to their previous positions, knowing that the initial positions were randomly generated as well.

Im creating flash game that have the functionality to capture/record its gameplay that can be viewed later by the user, like a replay.
As for now Im already able to record the game and write it into a flv format in a ByteArray variable.
What Im working right now is how to send that ByteArray(the video file) to a php script and save it to a web server.
I've run into the URLLoader in flash where it can send the data and php will receive it thru the POST method. Unfortunately, the ByteArray containing the flv data must be first correclty encoded for php to read it. I figured this out from the example in the net where it does the same thing only that it is only sending a JPEG ByteArray instead of a FLV format using the JPEGENCODER.
Is there any existing class like the JpegEncoder for FLV format or any Video formats? Or any work around like creating the encoder my self?
here is my current code to send the ByteArray
//send byteArray to a php script
var request:URLRequest = new URLRequest(url);
request.method = URLRequestMethod.POST;

I have a scheduling application that allows users to save any changes. When the user clicks the save button, Flex sends all the information to a coldfusion script which picks the information apart and sends saves it to the database.

I have an instance of a movie clip on the stage that jumps to different labels (within the movieclip) when the large buttons at the top of the scene are in rollover state. The problem is that it stays there when the mouse leaves the button.
How do I make that symbol go back to frame one (not there) within the movie clip so that it disappears when there is no activity on the buttons?
Is there a button parameter like MOUSE_OFF (I know that's not one)?

I have a ProgressBar in MANUAL mode responding an URLLoader's progress events that seems to get drawn far less frequently than I would like. If I debug the app, I can see many events firing from the URLLoader yet it seems that the ProgressBar is being re-drawn at some random and slow rate.
Now if this was my own code (URLLoader is a black box), I would pause once in a while to let the UI update, say via loop with a timer. I presume that the URLLoader itself is blocking the main thread from processing drawing code. Adding validateNow() and invalidateDisplayList() does not seem to help much.
private function onLoadProgress(resource: TResource, evt: ProgressEvent): void
{
_progressDialog.prbCurrentItem.setProgress(evt.bytesLoaded, evt.bytesTotal);
_progressDialog.prbCurrentItem.validateNow();
_progressDialog.prbCurrentItem.invalidateDisplayList();
}
Now there are many TResources (just a class that can manage its data) being loaded in sequence, but the URLLoader is so greedy that it does not let the UI get updated more than a few times when loading & processing (parsing into XML objects) 50 or so 10KB files. So just counting which files loaded visually does not work either; I'm lucky to get 2-3 screen updates the entire time.
Loading a 700MB file looks much better, but again the progress bar updates are random and slow.
Additionally, I'd like to know if there is any way to influence or even control the rate at which ProgressEvents are fired by the URLLoader class. I have not been able to find at what rate it normally dispatches progress events either; is it at a fixed percentage per file or every x frames or milliseconds?
As these are local files, would I be better off not using the URLLoader class and instead switching to FileStream?
