Flex :: FileReference And ByteArray Compress?
Oct 19, 2011
I have a FileReference that is being uploaded. But before upload, I call the compress() method on the ByteArray of the FileReference i.e. fileReference.data.compress().
But I observe that the uploaded file is the raw file and not the compressed file.
Is this a Flex bug or expected behavior? The data field in the FileReference is read-only. Does that come into play?

I work on a Flex application that creates compressed files and uploads them on a server. The files are created with ByteArray.compress method, which is zlib compression. I can decompress them using Python API on the server but I prefer to keep the files compressed there. I want to be able to download and decompress the files later, however WinZip and WinRar fail to decompress them. When I google for zlib utility, I only find zlib dll library. I need a simple application for Windows (and/or Linux)

I am trying to retrieve the ByteArray from a file selected using the FileReference class so that I can pass this to a Web Service call that I am making to Sharepoint.Is there any way I can do this using Flash Player 9 without having to upload to a remote server first and then downloading the file to extract the ByteArray?
This is assuming you can't use Adobe Flash Player 10 and the data property from the FileReference class.

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.

I am trying to use the load method of FileReference object to load the data and use it to display a thumbnail of the selected image.However, after calling fr.load(), fr.data remains null.I'm using Flex Builder 3.0.2 on Windows 7 with Flex SDK 3.4 and Flash Player 10 Debug. If I evaluate fr.load() in Eclipse's watch variables list, I get an error reading "No such variable: load."

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...

i'm using AMFPHP to stream content from my server to my Flex application, since Flash is a clientside technology i would like to make it harder for people to grab protected files, so i created a system that streams swf file to another flash player, i've done all the testing on URL stream, now i want to pass the swf file to the player as bytearray .. since i think it's safer and harder to break and in the future i even might do some encryption of my own if i became more familiar with bytes and bits .. anyways is my method the best one? (SWF to ByteArray?) or is there a better one? if the bytearray method is the best, i am facing a problem in outputing the swf file in the right format, i'm using a very primitive method .

I'm using this code to embed an image into my flash file:
[Embed(source="images/grass01.png")]
As you all know, if you embed an image, it comes in without any compression at all.
Is there any way to compress this image without having to do it manually? (I have hundreds of images that will be embedded).
I came across this link [URL] but I assume this is a flex only thing, as I get an error if I try putting the compression variable in my embed tag.

I have an array of objects. Each object has 3 integer fields and 2 binary fields.I've utf encoded the binary data and json encoded the array & sent it to Flex client side.On the client side, decoding data, I've got a String representing the binary data (utf decoded).Now, how can I convert this String to ByteArray? Or how can I read each byte of the String?

I am trying to create a file format for myself, so i was forming the header for my file. To write a known length string into a ByteArray, which method should i use, writeUTF() or writeUTFBytes(). From the Flex 3 language ref, it tells me that writeUTF() prepends the length of the string and throws a RangeError whereas writeUTFBytes() does not.

I'm trying to upload a bytearray, but am struggling to make the content-type go as image/png (it always goes as application/octet-stream no matter what I do.).I've checked the request with Charles Proxy, and can confirm that it indeed always goes as application/octet-stream.My code is:
protected function onObjectLoaded(event:Event):void
{
var byteArray:ByteArray = new ByteArray();
var fileName:String = fileReference.name;
var uploadPath:String = serviceURL;
[code]....
how to change this, so the bytearray itself gets passed in as image/png instead of octet-stream This image is being upload from the client side, and being passed as a FileReference, which I then invoke load(), and then get it's "data" attribute, which is where the bytearray is.

how to convert a file I have on my server (pdf/excel/ppt) to a ByteArray. The reason I want to do this is to display the dialogue open/save as to the user and I must set the Content-Type to octet-stream. The dialogue shows fine with just navigateToURL() but for pdf's it is the user's local browser setting. For a URLRequest I must set the data as a ByteArray. I'm trying to use the code located here:

I have to load a large xml in flash and I'm trying to send it compressed. To do that I tried to zlib compress the string and send it base64 encoded. In flash I turn the string into a byte array and use its uncompress() method. So far I tried:ZLIB.NET
byte[] bytData = System.Text.Encoding.UTF8.GetBytes(str);
MemoryStream ms = new MemoryStream();
Stream s = new zlib.ZOutputStream(ms, 3);

I'm using FileReference to retrieve an exported CSV file from the server. The fileReference.download(url, "myFilename.csv") method call seems to be working and I can download the file.
The only problem with this is that I can't seem to be able to set the file filter. In my save dialog, the file type filter is always *.*, which is really bad. The user trying to save the file has to manually type in the .csv extension. How do I change the filter of the dialog box to only show *.csv and not
