ActionScript 3.0 :: Loading Variables Using URLLoader And URLRequest
Feb 18, 2010
I am building a simple swf that will load in variables from an asp page using a URLloader and URLRequest. The asp page loads in the current values from a SQL database but these values will change every second. My swf loops every 6 frames and loads the data. How much load this puts on the server? And when the server is busy might this cause a problem with the variables I am reading in?
Does AS3 run all actions on frame 1 before going to frame 2 etc? I don't know if this is the best way but my last variable in the ASP page is called Loaded and I test for it before moving on. My major concern is the load I am putting on the website but is this small? In firefox the status box constantly flickers transferring data from ... and waiting .. but in other browsers you can't see the activity.

What is the difference between URLLoader and URLRequest in Actionscript?

I need to parse a particular web page every 25 seconds in order to take some particular values that are frequently updated in this web page. I need the parsed values in order to dinamically fill some text inputs components. So I write the following script:
Code:
import flash.events.Event;
import flash.events.TimerEvent;
import flash.utils.Timer;
[Code].....
With this script I'm able to get the webpage and parse the particular line of code that I need but only the first time! When the timer goes to zero the URLLoader function always loads the first version of the webpage and not the one that has been updated in the meanwhile! So I have always the same values! Using the trace function I have discovered that URLLoader loads the first version of the webpage. I don't know what is the problem here. Cache problem? URLRequest or URLLoader problem (maybe I have to clear the previous data?)?

there you are, you set up your AS3 code to load XML via a URLLoader and URLRequest, as normal. You then take your XML file, and upload it to a server. You then run your program, and trace out the XML you receive. So far so great, and you see the results of your XML traced out. Then you change something on your XML, either adding to it or removing a line. You then run your program again from CS5.5, and trace out the XML, and it shows the same results that it did before you made any changes. I deleted the XML file from the remote server, and it is like it stored it in cache, and still able to read it. If I change the url or file name, it gives me an error, which it should.
If I point the url back to my remote XML file, and run the program again, it gives me the XML results I had in the beginning, before I made any changes to it (regardless if the XML file exists). The only fix I have found so far, is closing CS5.5, and reopening, and then it can see the changes. I did that, and it was able to see my XML changes on my remote server, but again, only one time. If I try to change anything, or delete the XML file, it still pretends as if its there, reading the results that it read the first time I run the program. Is this a cache issue? Anybody else experience this? I never remember running into this problem using CS5/CS4/CS3, only CS5.5. Of course, I can test it all locally first, and then upload the XML file to the remote server when I know that no other changes need to be made, but still, this is really weird!

Peek-a-boo, me again. I'm having some trouble with loading in a txt-file and I can't figure out why, as it works in a new .fla file as well. Here's the code in a nutshell:
PHP Code:
goldstar.addEventListener(MouseEvent.MOUSE_DOWN, showHS);
var weekrequest:URLRequest = new URLRequest("weekscores.txt");
var weekloader:URLLoader = new URLLoader();

I have written code to read an XML file by using URLRequest and URLLoader in ActionScript 3.0. Code is pasted below. This runs well in AS3.Problem I am facing is because I wrote this in AS3, I am not able to use the DateChooser component in another part of the flash module because it seems like DateChooser component is not supported in AS3. So I want to migrate my below AS3 code back to AS2.
**** Code in AS3 (I need help in writing equivalent code in AS2) :-
var xmlText:XML ;var xmlReq:URLRequest = new URLRequest("myFile.xml");var xmlLoader:URLLoader = new URLLoader();

So let's say we want to load some XML -
var xmlURL:String = 'content.xml';
var xmlURLRequest:URLRequest = new URLRequest(xmlURL);
var xmlURLLoader:URLLoader = new URLLoader(xmlURLRequest);
[Code]....
I hate that you can't just say e.target.src or whatever - is there a good way to associate URLLoaders with the URL they loaded data from?

I am trying to setup two variables:
var xmlURLLoader:URLLoader = new URLLoader();
var xmlURLRequest:URLRequest = new URLRequest();
I am taking some old AS code and trying to plug it into Flash Builder. I am getting a "Type not found."warning with those variable declarations. Does anyone know which package to import?

when handling data, i always have to write the following:
var dataSourceRequest:URLRequest = new URLRequest("/path/file.xml");
var dataSourceLoader:URLLoader = new URLLoader(dataSourceRequest);
dataSourceLoader.addEventListener(Event.COMPLETE, handleDataSource);
while i can understand the usefulness of these 2 objects and event listener being separate, since they often work with each other i'd like to know if there is a method that will combine them all? the closest i can get is this, but it's a bit pointless/nesting:
var dataSourceLoader:URLLoader = new URLLoader(new URLRequest("/path/file.xml"));
dataSourceLoader.addEventListener(Event.COMPLETE, handleDataSource);
what i'd really love would be something that automatically combines the URLRequest, URLLoader and completed event listener like this:
var dataSource:Whatever = new Whatever("/path/file.xml", handleDataSource);

I have a queue of messages that I would like to send to a URL and I would like to remove messages from that queue only after I am sure they have been successfully sent. To do this I need to know in the COMPLETE event for the URLLoader exactly what data was sent so that I can remove the correct message from the queue.That is if I have something like this.
var urlRequest:URLRequest = new URLRequest(targetUrl);
var urlLoader:URLLoader = new URLLoader();
urlLoader.dataFormat = URLLoaderDataFormat.TEXT;

I am working on a flash website that loads live inventory data from a public csv file publish by google docs. the csv file is located at a public address on google docs server:[URL].. I am using a URLloader and URLrequest within my flash movie to grab this data and assign it to different variables.
It works great when I preview the movie in flash. However, when I go to publish the movie and preview the html file its loaded into in dreamweaver, I get a security warning from adobe flash player: Adobe Flash Player has stopped a potentially unsafe operation
I went ahead and published the html file that contains the swf file to the web, and when I go to my site, I don't even get the flash player warning; it just sits there like its trying to load the URLrequest and never completes.
I understand that flash player has a security measures that prevents flash files from accessing files outside of the server directory that the swf file is published to. I know you can create policy xml files to tell flash it's okay to load the data, but those policy files have to be located on the public server from which the data is being grabbed. But it's not like I can waltz on to google's servers a stick a policy file in there!
Is there any way to tell the flash player it's okay to load this data without getting that security error? I can't have the end user having to go into their flash settings and adding the location manually. I just need it to work without the security warning.
Is there another method of loading data from an external server without tripping up flash player security? aka, something other than URLloader and URLrequest?

I'm retrieving variables from a DB via PHP via the URLRequest, and the formatting is set to variables (URLLoaderDataFormat.VARIABLES) and matches the structure "myVarName=myValue&myOtherVarName=myOtherValue&... ".
My question is; is there a way, within Flash, to identify the variables and their values, without having to know their names?, are there methods within the loader class that allow this?, such as the variables count etc?
(I can access the variable "copyrightTxt." via the syntax: loader.data.copyrightTxt because I know its name, but I'd like something like
loader.data.variableSent[45].name = "copyrightTxt"
and
loader.data.variableSent[45].value = "@ 2009"
and
loader.data.variableCount = 98

Recently i got job that finaly includes some AS3, so im getting back into the world of flash again. But as you all can imagen, not without problems... let me explain what i'm trying to get working:
A little background:We are currently recreating a game within flash, the game requires a login to create a sessionid (server side) to retrieve gamedata based on that sessionid. The login page for this, is done with a certain framework (cake), wich we are not going to change, because the existing game is already in production phase.
The problem:The original form sends the username and password with nested variables like this:
<input id="LoginUsername" type="text" value="" maxlength="40" name="data[Login][username]"/>
<input type="password" id="LoginPassword" value="" name="data[Login][password]"/>
AS3Trying to replicate the request in as3 like this:
[AS]
public function login(username:String, password:String):void{
var loader:URLLoader = new URLLoader();
var request:URLRequest = new URLRequest(this.baseUrl + this.loginPath);

this piece of code:
PHP Code:
var mySoundReq:URLRequest= new URLRequest("samplesound.mp3");
var mySound:Sound = new Sound();
mySound.load(mySoundReq);
How does the urlrequest know where that .mp3 file is located, and how do i tell as3 where it is? and another thing: when i put this on the web, how do i locate the file then?

I am loading a sound file with the URLLoader class passed to the URLRequest class, just as one would load any other external content type.
Code:
var loader:URLLoader=new URLLoader;
loader.load(new URLRequest("file.mp3"));
When the loading is complete I would like to pass the data to a Sound Object.
Code:
var mySound:Sound=e.currentTarget.data
The object returned on the complete event is of type flash.net::URLLoader.
Code:
e.currentTarget
How can I turn this URLLoader into a Sound Object?

I'm using a bulk image loader from FlashAndMath. The code has you send a list of images to load and it simultaneously attempts to load all at once, adding each load req to a list.
My problem is that when one doesn't load and throws an error, I don't know which load request failed. Are there built-in ways to get it to report what image it was trying to load, or at least which of the load requests threw the error? I tried doing an event.contentTarget.content.name and it reports an instance #, but not the name I tried assigning when I called the URLRequest.

I want to make an application that loads some images with a Loader by making URLRequests to a local folder. Can I build the application and include somehow this folder so when I send it from a server to a client the URLRequests operate normally on clients side? Also if this is possible, the folder may be not viewable/accessible by the client but only from the Flash application that comes with it? So for example, this piece of code that runs nicely, locally, to my machine, if i send it to a client will continue to run to its machine. Can somehow send the folder and the SWF as one object?
private function clothesOn( outfit:String ) {
var clothier:Loader = new Loader();
var item:String = "clothes/" + outfit + ".gif";
var getItem:URLRequest = new URLRequest( item );
clothier.load( getItem );
this.addChild( clothier );
