I have Flash website, and I load data from XML file with urlLoader. If I change data in XML-file, refresh doesn't update data in site. I need to publish it again! How can I make this automatic, that I only need to refresh when data is changed? I can't allways publish when I change somethin in XML-file.
View 3 RepliesI understand the Flash and AS3 is single-threaded, at least at the user level. I would like to understand how asynchronous data loading is handled by the Flash player.
For instance, if I run CPU-intensive code that runs beyond the normal frame (lets say it runs on ENTER_FRAME, and consumes 1/4 per call). Does this leave any CPU cycles to load data from a URLLoader?
If http loading is truly synchronous, right down to handling the TCP/IP stack, one would get horrible performance. In Windows programming, I can do http access asynchronously (in which case the Windows libraries are doing either input on a separate thread, or doing hardware-level interrupts to handle the data -- I provide an asynchronous callback that may be on its own thread). Or, I can do synchronous download, in which case there will be hardware buffering, but my application is actively waiting for each buffer of data to be delivered by the hardware/OS combination.
URLLoader is asynchronous, but what does that mean? Does it mean that I can run the CPU and still download data? Or, will my download speed slow to a crawl if my Flash application is under heavy CPU load? Understanding how this works will help me design my product better, which both uses a lot of CPU, and downloads a lot of data (to the bandwidth limit of the network, if possible).
1 - SWF must have ability to loading binary data from any domain.
2 - SWF cant load policy XML file from url, cause upload form allows me only to upload swf files, so I cant include any other data.
I tried:
Security.allowDomain("*");
But it works only for SWF files.I tried to embed policy XML file:
var dataXML:XML =
<?xml version="1.0"?>
<!-- http://www.foo.com/crossdomain.xml -->
<cross-domain-policy>
[code]....
This will make an security error, if file is from different domain than SWF file.Its possible to get binary data from JavaScript using ExternatInterface in AS3 code.Here is cross-browser library for reading files binary: binary reader and later version jDataView.
I use flex builder to compile a single class to load an text data from the same domain.it works perfect in IE browser. But something is wrong with the firefox browser.take a look at the following code:

I am trying to get my PHP variables from my load.php document to my flash-document.That all works fine and I am able to get my data down to flash variables inside my function.But, I would like to be able to access this data from outside of this function which gets the data - unfortunately I cant, or.. Don't know how to. I hope that you are able to shed a light upon my problem. So here goes, this is my code:

How to retrieve xml data in an aspx page after sending it using URLLoader.load
This is the flash code i am using:
var urlLoader:URLLoader = new URLLoader();
urlLoader.dataFormat = URLLoaderDataFormat.TEXT; //tried by giving VARIABLES also urlLoader.addEventListener(Event.COMPLETE, handleComplete);
urlLoader.addEventListener(IOErrorEvent.IO_ERROR, ioErrorHandler);
[Code]....
I were able to accept data in above statement when i send a string in var1 say "test". But on sending xml above error is getting.I have tried to load the xml data in XMLDocument also.
In AS20 i used sendAndLoad method to send and reterive xml data.
I am making rest calls with a urlload.load(urlRquest).
also
urlRequest.method = URLRequestMethod.POST;
urlRequest.contentType = "application/xml";
When I make the calls within the Flash IDE, I get HTTPStatusEvent.status = 400 (or whatever) when an error occurs. And the IOErrorEvent.data contains xml (or sometimes a string).
However, when I run the swf in a browser (Firefox Mac or PC), the HTTPStatusEvent.status = 0, and the IOErrorEvent.data is empty. (Interestingly in Safari Mac, I do get the 400 status, but still no data.)
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.

I'm currently working on a project that contains a lot of data, about 14.000 records. This means an xml file of about 3mb. Now my question is: Should I use the xml file to load all the data at once, or should I use a webservice, that provides the data when I need it? Keep in mind that I'm new to webservices. And if I'm going to use a webservice: How do I store the data, in a mySQL database?How fast is a webservice?
View 1 Repliesin AS3 I'm trying to load a URL (a Yahoo address) into the application so I can process the source code and pull things out of it.However, when I load it, or any other page, I get 0 bytes back.Here's my current code.

All Im trying to do is post firstname, lastname and emailaddress from a form inside my swf to a php file and then get that php file to return a result back to my swf.
First of all i tried using external interface to handle this because the server its going to run on doesnt support PHP.
I had the SWFgrab the data from the text fields, pass the data to JS through external interface, then the JS would use jquery AJAX to execute the php file, then the JS would grab the results from the AJAXd div, then pass the data back through to the SWF. It was a bit of a circle jerk but it worked.
However, the PHP script that needs to be executed in a different domain as the SWF. I forgot that this would cause an issue. I then tried to setup AJAX crossdomain policies, but this is going to be a reasonably high traffic site and i felt that the proxy options that i found were kind of slow.
I realised that what id been doing so far was probably over complicated anyway. So, i went back to basics and thought id try using the URLLoader to load in the php file as a string. I setup a crossdomain.xml file on my server that will be hosting the PHP and used the loader to grab the PHP file.
This works fine, all the PHP does is echo out 3 comma separated values which i then split into an array and use in my SWF. I get the values no problem. However, my status bar in firefox keeps saying that its still transferring.
Ive tried telling the PHP script to 'exit();' after its echo'd out my results. Ive tried telling the URLoader to .close(); when its grabbed the data, neither of which stop it from transferring. Im also using the web debugging proxy 'Charles' and that says that the connection opened and closed successfully, but firefox still says that its transferring.[code]...

Im working with this little sidescroller tile based game, im saving maps to xml file. But got this little problem. I would like to do something like this.
var currentLevel:int = 1;
var myMap:String = "map" + currentLevel;
var myMap = xmlData.myMap.tiles.text();
so i would like to put that variable to that getting data from xml so if my currentLevel changes its getting diffrent data from xml file. so is that possible to put variable to that xmlData.myMap.tiles.text();
In my app, I load multiple xml files. And to load those, I always create a new URLLoader. Nothing special. The first file works fine, the second one does, too. The third one, however, reports to have loaded fine, but the data it holds is actually the data of the second file. The current workaround is to load the third file twice, which somehow works... weird.

View 5 RepliesIm 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 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.

var urlLoader:URLLoader = new URLLoader();
