Flash :: Where's A ByteArray's Data Stored
Oct 29, 2011
I'm using URLStream to download a big file and save locally on a mobile app. To do this, i need to store the downloaded bytes on a ByteArray:
private function handleStreamProgress(event : ProgressEvent) : void {
if ( urlStream.bytesAvailable == 0 ) return;
if ( urlStream.connected ) {
[Code]....
Are these bytes from the downloaded file stored in Memory? (Profiler doesn't show any excessive memory consumption, though...)
Should I clean the byteArray after each sequence of bytes is stored?

I am new to Flash and ActionScript platform. Presently, I am using ActionScript 3.0.I know only basics of Flash but not in depth. My issue starts here: For example, In Windows Operating System, Paint-brush uses Clipboard for temporary storage. My question is: Does Flash have Cache(i.e., buffer for temporary storage)? If Flash has Cache, then where does the temporary data gets stored, in what form, is the data accessible or atleast viewable?

Im having a bit of trouble integrating dynamic variables pulled from a databse using an ASP script with a flash movie.
Background:
I need to send variables stored in a ms sql db to a flash movie to display several values.
The dyanmic element comes in because i am using an ID to select the values from the db e.g id1 = joe bloggs id2 = paul smith
etc
When i am hardcoding the id in the asp script the variables are sent to the flash movie no probs and they display correctly.
I am also printing the asp code on the page and that all displaying fine.
HOWEVER, the issue arises when i make the asp code dynamic and by that i mean I am using request.querystring to pull the id
from the URL - The print out of the asp code is still displaying the correct variables, BUT they are not being passed to the
flash movie at all - the placeholder is blank there isn't event an error!!.
Couple of things to note -
- if you change the id bit of the url in the dynamic script to the printed asp code changes
- THE FLASH MOVIE IS IDENTIAL in both scenarios
- all variable names have remained the same
- it is NOT a location of file issue as we have tested the dynamic code files In another folder and no joy
- we are not using any other file includes or asp code in any of the page - all other code has been stripped out
THE ISSUE WE HAVE IS THAT THE PRINTED VARIABLES ARE NOT BEING PASSED TO THE FLASH MOBIE in scenario 2 where the asp code is looking for the participant id dynamically (i.e from the URL)

I am using the FileReference object. I want to be able to save the local file data into a ByteArray. I know that I can use the data property in Flash 10, but I would like a solution that works for earlier versions of Flash.

According to the NetStream API, Flash can play LOCAL RAW video by calling ns.play("raw:filename");.My question is how can Flash play RAW video data from a ByteArray? I have basically set my NetStream object to data generation mode by calling play(null), but whenever I call ns.appendBytes(byteArray) nothing is happening because apparently, appendBytes only support FLV data. how can I make Flash play raw video data from a ByteArray?

I'm able to record sound with a Flash application embedded in my website, this audio is saved to a ByteArray, which I need to pass to Javascript in order to post to my server along with other required data.
I know I can use AS3 ExternalInterface class to communicate with Flash from Javascript, but what would be the appropriate format or variable type in javascript to hold the ByteArray, and how can I ensure that I won't lose much audio data when doing so?

I was wondering... i thought this might be a dumb question to ask but ive been wondering if it is possible to remove all the data that was inserted into an array?
i.e.
ActionScript Code:
var loadAllThumbnails:Array = new Array("poop1", "poop2", "poop3", "poop4", "poop5");
someBtn.onRelease = function(){
//clears/emptys the array when released
}

First time on here.We teach English through games. All done on flash AS3 now. Want to put courses online so I have been told to use php to communicate to server and database. My question is:Do I use mysql to save stats or xml FIRST: I will get info from xml and send it to my activities in flash - I'm OK with thisSECOND: I want to send out stats from flash to mysql OR xml. The stats are:1. Student logs on of course using username and password (well that comes in not out)2. What lesson the student is on ie: 2, 3, etc...3. Highscores for game activities4. Scores student gets on each activity As far as I can see the only stats that grow are the scores on each activity and even those could be erased periodically.

i'm trying to perform simple automated test on my Adobe Air Application. I decide to store some test data in external MS Excel file to decrease hardcode quantity. But I discovered, that this is not a trivial task, when you're working with Adobe Air.
Actually, i need to correct initialize an excelApp object, the rest part of logger is already implemented. I tried the following approach, but I can't find a package with ActiveXObject class defined.
excelApp = new ActiveXObject("Excel.Application");

Once a button is clicked in a submenu called SelectChar(a menu class extending my menu base class), it dispatches a custom event carrying an array of variables. This event is then listened for in the main Document Class called Engine, where the value of the passed variable can be used. For testing purposes im only passing 1 arguement in the array.
my Error when trying to trace the passed variable in isolation "trace(e.arg[0]);": 1119: Access of possibly undefined property arg through a reference with static type flash.events:Event.
Okay, i hope that made sense... heres the relevent code:
custom event class: passCharEvent.as
Code: Select allpackage com.asgamer.snipergame
{
import flash.events.Event;
public class passCharEvent extends Event

For various reasons, I would prefer to store binary data like images and videos as BLOBs within a MySQL database and have Flash retrieve that content directly from the database as opposed to getting it from a URL on a fileserver. So, I have written a PHP script that Flash calls which does a database query and returns the bitmap data from the BLOB. I have verified that the image data is being sent from the database through the PHP, but Flash either doesn't display the image or gives me an error saying that it is an unknown type.
[Code]....
Is there a way to get Loader() to accept bitmap image data that is retrieved from a BLOB in a database? Should I try to get PHP to mimic the response from an HTTP server or is there another way to load bitmap data stored as a BLOB into a display object?

I want to extend the dictionary class. Everything works so far except that in some of my methods that need to reference the dictionary's content I make a call like:
this[ key ]
It doesn't like that. It just tells me that there's no property 'key'. Is there a way to way to access the data within this class?Also, I'm using an integer for the key.
Edit: I've found that the same behavior happens when you extend Array.
var myArray : Array = new Array();
trace( myArray[ 0 ] );
var myArrayExtender : ArrayExtender = new ArrayExtender();[code]....
Where in this case, myArray returns "undefined" and myArrayExtender throws error 1069. ArrayExtender is an empty class that extends Array and calls super() in the constructor.

I'm looking for a good method to compare a single bitmap data instance against an array of stored bitmap data objects. I need to figure out how I can compare and arrive at the conclusion that the result either means that the images are of the same object/aka similar or if they are two totally different images. I tried checking threshold of the result of the compare() function but my efforts have failed so far.

I'm currently working on a small project. The user is supposed to draw/do a puzzle within flash, and also fill out a form with his details and comments.
When clicking the send-button, the image should be sent along with the form as an email.
I already know how to send the image as an email via php, and I know how to send a form as an email via php, BUT - I can't seem to do it together.
I've googled a bit and I found out that I cannot pass both the bytearray (from the image) and the form-data as URLVariables at the same time.
One way I got it to work is by passing the values from the form-data as a part of the URLRequest (and then use $_GET in the .php-file), but this has limitations as it can only pass 100 characters. As the user should be able to comment on his work, using GET with its limitations isn't an option.

I would need to save some binary data (bitmap data or similar) as a part of XML file.[code]...
I suppose I must serialize or encode "ba" (binary bytearray data) some way to string before writeing to XML and decode them back during the reading from XML, but I cannot find the correct way how to do it.

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;
[Code]....

I have a byteArray of recorded sound.But how can I transfer the ByteArray data back to a real Sound object?I know that I can pass the ByteArray to an SampleDataEvent.SAMPLE_DATA listener , but that way I would have to keep the raw ByteArray and pass it every time the sound plays.

I have an AS3 swf which users can upload jpg images to my EC2 instances which sit behind and Elastic Load Balancer. The jpg images are converted into bytearray data and sent using URLLoader.load(URLRequest)I make 2 calls when uploading, one to upload a large version, then another to upload a thumbnail version. A PHP script to which the bytearray data is uploaded converts this to a file using file_put_contents($destination,$GLOBALS["HTTP_RAW_POST_DATA"])Is it possible to combine these two requests into a single request which contains both the bytearray data for the large and thumbnail images and 'split' the HTTP_RAW_POST_DATA to create 2 files at the server. This would be better than uploading the bytearray for the large version then using something like ImageMagick to resize the resulting image into a thumbnail which I realise is another option.

I am working on a game, made with Flash (using AS3) The game has a fast ball and when this ball hits an object it has to make a sound... but the sound starts with delay (so the ball is far away when the sound is played).This sound is edited by me and it hasn't got any silences at the beginning.The method i'm currently using is the simplest one:
public var sonidoPuntos1:sonidopunto1 = new sonidopunto1()
and then...
sonidoPuntos1.play()
I am trying to introduce the file into a ByteArray and then playing it from there...
