Flex :: Deseralize Vector.<String> From ByteArray?
Jan 27, 2011I got this situation:
var vector:Vector.<String> = new Vector.<String>();
vector.push("uno");
vector.push("dos");

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?
View 1 RepliesI have some binary data and I can't store it in a string, as such I'm using a ByteArray. The problem is that I need some functionality that comes with strings, to be specific I need the charAt, substr, indexOf and substring methods.
View 1 RepliesCreated Vector with the initial length of 100.
var v:Vector. = new Vector.(100);
v[90] = "Ninety"
v[190] ="oneninety" //RangeError: Error #1125: The index 110 is out of range 100.
//How to change the length from 100 to 200 to store a value at index 190
I've been asked to implement and MD5 hasher ActionScript-3 and as I was in the middle of debugging how I formatted my input I came across a problem. When I try and output the ByteArray as a binary string using .toString(2), the toString(2) method will perform some short cuts that alter how the binary should look.
For Example
var bytes:ByteArray = new ByteArray();
bytes.endian = Endian.LITTLE_ENDIAN;
bytes.writeUTFBytes("a");
bytes.writeByte(0x0);
var t1:String = bytes[0].toString(2); // is 1100001 when it should be 01100001
var t2:String = bytes[1].toString(2); // is 0 when it should be 00000000
so I guess my question is, might there a way to output a binary String from a ByteArray that will always shows each byte as a 8 bit block?
What is the simpliest way to find an occurance of some sequance of bytes (string) in a long byte array?
UPD: I tried to do
my_byte_array.toString().indexOf(needle_string);
the problem is that in flash/air string consist of utf8 characters, so indexOf will return value different from offset of "string" in a byte array (actually it's zip archive)
To put it simply, I have this string filled with 0's and 1's (terrible right?) What's the quickest way to divide it by 64 and put it into a bytearray? (with the bits as the char's value?)

Maybe im just too blind to see it. I have this string with 0's and 1's and im just trying to turn it directy into a bytearray. I'll optimise it later, im just getting really annoyed at the fact that this isn't working.. Edit: I even tried working with an array. The data is there it's just not being written into the bytearray properly.
I need to take a string and convert it to a bytearray. such that the return is of type ByteArray. I thought writeUTFBytes(String) would work cept that returns type Void.Im not seeing anything in the docs about returning a bytearray

I'm working on a small web project Combines between flash AS3 and php ,the project Depends on three steps...
1- convert bitMapData to byteArray |with JPGEncoder |
2- convert byteArray to String and Send it to php and data Base.
3- receive again the string byteArray from php and convert it again to byteArray.
the problem is STEP3 >> How to convert String to byteArray??
I have a string, I am compressing it with bytearray and save it to a file. In other application I am loading it and when I try to uncompress it, it's give me an error. How can I convert a compressed string in to bytearray type to be able to convert it? The code for compression:
var b:ByteArray = new ByteArray();b.writeMultiByte(t,"iso-8859-1")b.compress();
i have a string which contains all binary data. the binary data represents a custom object in my application.
i want to convert all the data inside the string into binary format and store it in a ByteArray. then I want to read the object from the ByteArray using readObject.
My program saves text files, which contain various text, some of which is a string representation of a ByteArray. It does this by using the toString() method of the flash.utils.ByteArray class, which I assume converts a ByteArray (for example, 13x$) into its string representation "13x$". So how do you reverse the process, and turn the string ("13x$") into a ByteArray (13x$)? Even if it's not that simple, I just need to have the ByteArray, put something in a text file, and extract from it the same ByteArray.

bytes.writeInt(0);
trace(bytes.length); // prints 4
trace(bytes.toString().length); // prints 4
When I run the above code the output suggests that every character in the string returned by toString contains one byte from the ByteArray. This is of course great if you want to display the content of the ByteArray, but not so great if you want to send its content encoded in a string and the size of the string matters.Is it possible to get a string from the ByteArray where every character in the string contains two bytes from the ByteArray?
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 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)

View 1 Repliesi'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 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.
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?
