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)
isn't there supposed to be a "ByteArray.writeUnsignedByte()" to go along with the "readUnsignedByte()",?[URL]

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.

View 1 RepliesI 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'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?
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();
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.
View 1 Repliesis there any way of searching a string from right to left and trying to find the first occurrence of like a letter or a fullstop or something like that? also is there any way of finding the index of were its located and then deleting all characters from left to right starting at what ever index value was returned?
View 2 RepliesI'm creating a flash application, which loads a file from a server, and stores it in a string. I'm wanting to find the substring within that string, which is inbetween two known substrings.
Note. I don't want to do this with reg-ex as i'd like it to be easily reusable.
Ideally I'd like a function which i can re-use, by passing the beginning and ending substrings.
e.g. something along these lines..
function getSubString(start:String, end:String):String
Edit: There may be more than one instance of the 'start' and 'end' substrings within the string, i'm wanting it between the first instance of each.
I 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 Repliesfinding a number in a string of text. how can i do this?
example:
var1 = "string of text 35";
trace(magical number finder);
output: 35
var 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 have a dynamic text field in flash that is populated by an input box. The dynamic text field has a maxmium width it can be. So i have it as multiline WITH wodrwap on. My problem is that I have to send this data to server and for the php to be able to text the text and output the text as it is displayed in flash. There seems to be no way of finding the linebreaks and passing them in the string as far as I can see?

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()

The person handling php says that only ByteArray needs to be send and conversion to JPG and PNG can be done from PHP side. When I built the option for saving on the local machine the following steps were used.
Converting to Bitmapdata
Using JPGEncoder and PNGEncoder on the Bitmapdata
Then assiging to byte array variable.
So in this case different byte arrays were used for saving in case of JPG and PNG and it worked.

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?
How can I get the size of a ByteArray in bytes? I want to know, to see the difference in data transferred before and after the compression of a string (via ByteArray).
