ActionScript 3.0 :: Convert String Representation Back To ByteArray
Oct 2, 2011
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.
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
One trick shown me that I could use bytes+"" which convert into String but not a pure String. It is acceptable by any UI components except it won't accept when I throw bytes+"" into switch statement. How do I convert bytearray to pure string?

Is there a way to write a UTF-16 string into a ByteArray in Flash/AS3? Basically I have a string (var test:String="allan"; for example) and I would like to write that into a ByteArray with UTF-16LE encoding. In this case it would be "61 00 6C 00 6C 00 61 00 6E 00".
I've tried using utf16le.writeMultiByte( clipText, "utf-16" ); but it just comes out with what appears to be UTF8 (or just straight ASCII given the test string).
The use case is to save a UTF-16LE file using FileReference.save(), which I understand I can do by passing it a ByteArray with the correct character encoding in it. Passing just a string saves as UTF-8. Hence the need to convert and store into a UTF-16LE representation in 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.
How to encode LONG_INT binary representation from AS3 Number data type (using ByteArray)?Need it for implementing data transmission protocol between client and server.
I'm looking for a fail-safe way to round-trip between a Flash swf file and a text representation and back again. One strict requirement is that the resulting round-tripped Flash swf file is exactly functionally equivalent to the original Flash swf file as long as the text representation is left unchanged. Furthermore, the text representation must be human-readable and editable. It should be possible to make small changes to the the text representation (such as changing a text string or a class name, etc.) which are reflected in the resulting class file representation. Is there a fail-safe way to achieve Flash swf file/text-representation/Flash swf file round-tripping given the requirements above?
Any way of doing this is as3? For example, if I have a var dog:String, how can I get "dog" out of that variable? Looking into reflection to do this, but there's got to be an easier way.
I want to convert a ByteArray wich contains a .flv file read through a socket connection to a video playable object and play it, or attach it somehow to the netstrem as its source. Why this ? I'm trying to write an app using AS 3.0 that connects two swf clients to each other directly without a server (after they know of each other) and allow them to exchange video sequences. So the reverse way video -> bytearray -> network -> reciever ->video would be of interest aswell.
The coding language is Java.I have a ByteArray embedded in ActionScriptObject.(Smartfox Server)I want to convert it into ByteArray.The idea is to save it as an image.This a sequel to the post --> Convert Byte Array from Action Script to Image in Java and save it
and the error message is: Error: Error #2030: End of file was encountered. The situation is i have store the image as binary into the database by convert the byteArray and now i would like to retrieve it and convert back to image.
Just to clear this up ByteArray Need to Place into Bitmap and then you can add to the movie Clip right?
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:
Is there any way to convert any displayObject to ByteArray? I can of course iterate through pixels, but thats not what i was thinking about, I would like to write ie MovieClip into ByteArray, and then read it back as it was.writeObject doesnt work for DisplayObjects.
How to convert AS3 ByteArray into wchar_t const* filename?So in my C code I have a function waiting for a file with void fun (wchar_t const* filename) how to send to that function my ByteArray? (Or, how should I re-write my function?)
I am trying to take data that I have extracted from a ZIP file in Actionscript, then convert it to a File object so I can write it to the documents folder for my air app to use.
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 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'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?)
ActionScript Code: private var counter:Number = new Number( 0 ); private function sequence(seq:Array):ByteArray {
[Code].....
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 have an animated MovieClip and I want to save it to computer as animated swf !is there any way to convert it to byteArray and send it to FileReferenc and save it ?I tried writeObject but it doesn't work !
