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 RepliesI'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?
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.
I m trying to write AS3 to take a screenshot of a MC thats on the stage and pass the data to a .cfc method which saves it as a jpg on the server.The current code I have kind of works except the jpg is unreadable.I think it has something to do with not using Flex, AMF, and writing binary files.When I look at the jpg via a hex viewer I think it doesnt have the right jpg header.The jpg begins with:c3 bf c3 98 c3 bf c3 a0 00 10 4a 46. When I think it should begin with:ff d8 ff e0 00 10 4a 46
//AS3 source code[code].......
So, as the title says I was wondering if it is possible to scale bytearray/binary data from lets say 640x480 which is being captured from the stage to 1024 x 768

unpacking data from a binary string. I realized it with a php code:
list($empty,$size) = unpack( 'V', fread($socket,4) ); $theresult = fread($socket,$size);
But how can i do this in as3 ? I didnīt find a possibilty to encode "unsigned long (always 32 bit, little endian byte order)". Is there a option like unpack in as3 ?

View 1 RepliesWhat 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 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();
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.
View 1 Repliesvar bytes:ByteArray = new 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 want to write a logging system to log errors but I want the format of the file to be binary. Can you write and/or read binary files in Flex 4? (actionscript to be more precise)
View 2 RepliesI 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:

and then...
sonidoPuntos1.play()

I want to retrieve file's binary content using flex but failed. Here is the code so far:
// ActionScript file
package source.fileApi{
import flash.display.Sprite;
import flash.external.ExternalInterface;
[Code].....
But this did not give me the binary content of the file.. how to retrieve the full binary content of the given file using Flex (I am using FP 10.0).....
I'm trying to evaluate whether Flex can access binary sockets. Seems that there's a class calles Socket (flex.net package). The requirement is that Flex will connect to a server serving binary data. It will then subscribe to data and receive the feed which it will interpret and display as a chart. I've never worked with Flex, my experience lies with Java, so everything is new to me. So I'm trying to quickly set something simple up. The Java server expects the following:
DataInputStream in = .....
byte cmd = in.readByte();
int size = in.readByte();
byte[] buf = new byte[size];
in.readFully(buf);
[Code] .....
After that - EOFException happens on the server and that's it. So the question is, am I approaching whole streaming data issue wrong when it comes to Flex? Am I sending the policy file wrong? Unfortunately, I can't seem to find a good solid example of how to do it. It seems to me that Flex can do binary Client-Server application, but I personally lack some basic knowledge when doing it. I'm using Flex 3.5 in IntelliJ IDEA IDE.
The jist of what I'd like to know and focus on understanding, is details on how binary deserialization occurs in Flex 3. When is the constructor called, when are properties set, are private members serialized or does all deserialization occur on and through setters, etc? I'm having a hard time finding information on this.In a Flex 3 AIR application, I have a pretty complex object graph(just a bunch of objects referencing one another, kinda like a big data model except a bit more complex) that I serialize to a file using a single call on the FileStream.writeObject and readObject on a root object, which serializes and deserializes the entire object graph.I found that I needed to always have a default constructor, else I would get exceptions on the objects when deserializing if they were part of an ArrayCollection. So I had to eleminate the constructor parameters or set default values. I now have many setters like this in my classes, such as the below where mConnection accumulates some information it needs through different setters, where as before I had this all packed into the constructor since all of the information is really necesary for the Connection to function:[code]So the connection's serverIP is still an empty string because the server was assigned to the client's property before the server was completely initialized.
I could probably resolve this by using binding so that updates to the serverip in the server are bound to the connection, but I find binding properties to be fairly complicated (it's really simple on UI in mxml cause you just use the curly bracket syntax but doing it by code is what I found complicated). I have also resolved some cases by removing the constructor parameters entirely, so that there is no default values. All that aside, I still really need a deeper understanding of the details of binary serialization as far as how it rebuilds the object graph. I even have circular references, and it seems to handle those fine and maintain multiple references without duplicating objects. It's just when my constructors/setters are more complex that I'm running into these problems because of the order of what occurs during deserialization. It is really inconsistent though, as adding breakpoints in various places seems to influence the order that things occur, making it more difficult to debug.On a side note for anyone that might sidetrack the topic because I am serializing a class called Connection. I added some code to address some things, like in the Connection class there is an instance of a Socket. Of course my socket would not be connected after I close and reopen the application and deserialize it, so before I serialize my object graph, I go through and close the socket and set the reference in the Connection class to null, so that there is no longer a reference to the socket and thus it will not get serialized. After deserialization on the next application run I create a new socket.
I'm new to Flex and couldn't figure out yet how to send binary data to the server as the body of a POST request. The HTTPService component doesn't seem to support this. The FileReference doesn't seem to support setting the data via the Flex API.
View 4 RepliesI 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)
