Actionscript 3 :: Flash Player Breaks When Loading .csv File With URLLoader
Mar 25, 2011
I've made a little flash, with AS3, to view the data generated by some program I wrote... The data is in a .csv file and are loaded to the memory with a URLLoader object.
The flash loads well .csv files which can come to almost 50 MB in size... But when I try to load a file with 160 MB, the player just stop working... I run the last flash player version, outside of the browser...
I've heard that the Flash has limitations on the amount of memory it can store... But in another question, they say it has not.
What may be causing the crash? - I don't think it is the code, since it runs smooth for small files...

does anybody have a good explanation of the as operator? On one hand it seems to me, that it is often better to use as instead of instantiating a new object.But then there are situations, when this operator let's me down. For example when loading a text file in XML format through an URLLoader:
private function completeHandler(event:Event):void {
var loader:URLLoader = URLLoader(event.target);
trace("completeHandler: " + loader.data);[code]...
Why do I have to use a constructor here? Why can't I say var x:XML = loader.data as XML; and save some memory?

I have run into a problem with the URLLoader that I havent encountered before. I have reviewed my code several times and maybe I am missing something.
Basically, I have a separate loader class that I want to communicate to a php file located in the same directory. That php file forms an xml markup within and returns the location of a background image from the database. As you can see from the code, I have event listeners for progress, loaded, and IOerror.
This works fine in IE and Chrome. However in FF and Opera, my custom progress bar shows 100%, but the info bar shows "IO Error" (which is kind of a visible trace statement on the swf for informational purposes) and it does not go anywhere.
This is the swf's location: [URL]
PHPGetBackground class:
package com.hexonite.loader {
import flash.display.Sprite;
import flash.events.Event;

I want to use getUrl to display a javascript alert. I've found an example that works perfectly, by using getUrl("javascript:alert('hello world')"); But that example is published for Flash Player 6, and the rest of my movie requires FP8. And if I go to publish settings, and select Flash Player 8 as target, the javascript is no longer executed.
It's not about the getUrl changes in Flash Player 9, I've also tested with Flash Player 8. If you want to try for yourself, the example I'm talking about is from [URL]..

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 am trying to load the output of a php-file into some flash variables and then fill some textfields with those variables. But it seems like even though I have a completehandler it tries to fill the textfields before I get all the data.
Code:
function loadQuestion(){
var request:URLRequest = new URLRequest("the url to my php script");
request.method = URLRequestMethod.GET;
var loader:URLLoader = new URLLoader();
loader.dataFormat = URLLoaderDataFormat.VARIABLES;
Is it wrong of me to have the completeHandler inside the loadQuestion function? And is it wrong of me to assume that because I put the data in the textfields in the completeHandler it should w8 until its finished loading?

I am a fairly new as3 user and am working on a video player that loads an xml file into a URLloader as a playlist. I have everything working but I want to add a few buttons to change the content of the playlist. All of the data will come from the same xml document, so I don't think i have to reload the xml. I can get the content to load when the button is pushed, but it jsut adds to the previous content instead of replacing i. How to clear the content before adding?
Here is my code (that relates to this) so far....
public class playlist_controller extends MovieClip {
private var xml_loader:URLLoader;
public function playlist_controller():void {
////load the xml file
xml_loader = new URLLoader();

I have a SWF that has a movie player in it. What I want to do is load an flv or audio file into the player from anywhere on my computer using a file browser. Currently it does work, but ONLY if the flv is located in the course folder where the SWF compiles to. How I can make it play an flv located anywhere other than in the same directory as the SWF?

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?

This matter is something I haven't been able to solve for long and now I'm really desperate to find out an answer. Here's a link to a very simple zip file (as example) containing the conflictive fla and other files, for those of you who may want to have a look at it. TO SIMPLIFY THINGS: It seems that whenever I use a couple of AS instructions to load some Dynamic text from a text file, Forms which are based in formmail, stop working (no matter if these forms are made of dynamic or static text). Why??
INTO MORE DETAILS: In the attached fla example file here, I've simplified things very much by just leaving 2 Forms (one made with Dynamic text and another one without any dynamic text on it). Very peculiar, if in frame 1 I call the variables from the text file:
[AS]webcontent= "File.txt" loadVariablesNum (webcontent, 0);[/AS] the 2 Forms stop working properly: The static one doesn't even seem to submit data and the dynamic one, it seems data has been sent but data is never received. As soon as I delete these 2 lines of AS, they work properly again (although of course, no words can be seen in the Form made with dynamic text).

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.

A client is having me convert an HTML5 video web application that I've already built into an AIR app.
The end users are going to need this to work with no internet access, so I MUST include a LOT of video files with the installer. This works fine on my machine, but my client can't install it because the .air file is too large and they don't have enough RAM. We'll need this installed on a number of laptops that aren't super powerful.
My SDK is up to date and we're using AIR 3.1. Has anyone else run into a similar situation? Is there any workaround? For instance could I either include both the installer and the .air in a zipped folder, then have the installer move the video files to the appropriate location, or use AS to have the installer download the files (they will have internet access when installing).

I'm using URLLoader to load my external SWFs in as a ByteArray before use so I can preload them without the possibility of them playing prematurely. It's been working great so far, but I just ran into an issue. It's not loading question pools for Captivate quizzes. If I use Loader.load() for my quiz it works fine and the question pool loads. If I use URLLoader to get a ByteArray and then use Loader.loadBytes(), I get an error saying that it can't load the question pool. My code is below. If you comment out the urlLoader.load() line and use the loader.load() one instead, it'll work fine. Otherwise, I get an error.
Code:
var loader:Loader = new Loader();
var urlLoader:URLLoader = new URLLoader();
addChild(loader);
urlLoader.dataFormat = URLLoaderDataFormat.BINARY;
urlLoader.addEventListener(Event.COMPLETE, done1);

I have encountered an interesting problem when I try to load an .xml file using a URLLoader (within my own custom class). I have several configuration .xml files which I use to configure the application when it launches. For example, in the code below, myCustomLoader is a custom class I wrote that takes an .xml file as a parameter. The myCustomLoader class encapsulates all the instantiation of the URLLoader class and error handling etc. The code below operates as expected, the configuration files load into memory, and they're accessible throughout my App.

Say I'm using a URLLoader to access a PHP file.Is there some way to verify, from the PHP file, that it is Flash attempting to connect?Like, does Flash Player send some sort of unique data to the server when requesting the page that I can use to verify the integrety of the data (in order to prevent people sending data to the PHP file from any other souce)?

I'm loading external logo into my SWF with following code: var request:URLRequest = new URLRequest("logo.swf");var logoloader:Loader = new Loader();logoloader.load(request);addChild(logoloader);logoloader.x = 5;logoloader.y = 5; Everything works fine as long as I have logo.swf in right place. Is there an easy way to improve that code so that it wouldn't matter if there is logo.swf, logo.png or logo.jpg as long as one of those files exists in right place? I just would like to give my clients change to use other formats than SWF if they like, because some of them doesn't have flash or any other software with SWF exporting capability. all of them have Photoshop or some other Image software....

I put together an .html page using a photoshop jpg that I sliced into sections. I was asked to replace two graphics from the original .jpg file with animated content of the same size. Using my slices as a guide for size, I created the two animated graphics in flash and saved them out as .swf files. They are both the exact same size(px) as the static images. I opened my newly sliced html file in dreamweaver, deleted the static images and placed the .swf files.
For some reason the .swf files cause gaps in my html page. Tere are no borders on the .swf files and I can't figure what I've done wrong.
One note: It seems to only ad space when viewing from Mozilla. Havent' tested it on a pc yet either.[URL]
