Actionscript 3 :: ByteArray Return Its Content As A String With Two Bytes Per Unicode Character?
Aug 13, 2010
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 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 encountered strange problem. I have created simple Flash text field control and I wanted to compare its content with some other string. This comparison in triggered when user is pressing the button.In Action Script 2.0 code I noticed that a caret return character () was added at the end of the string coming from the input text field.It is easy to overcome the problem obviously, however I would like to understand what is going on. I use Flash CS4 with AS 2.0.
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).
I have the unicode for that char, how do I display it? 0x023D2A textField.text = ???; I have have the name of the character. Can I reference it by name?
I'm working with IPA Character embedding in Flash CS4. I can get almost all the characters to display properly, but "U+2C71" is giving me a problem.This works:
It's like it's not even trying to find the Unicode character. Adobe says that everything up to uFFFF is supported, so I don't have any idea why it would be doing that
I'm having a problem with "&". Basically I haven't been able to escape this correctly in Flash AS3, however I did find this link which seems helpful: [URL]
use unicode character 187 (hex:BB) or ascii character 174 as a seperation character in my mysql database.This was working great in one of my swf files but not flash keeps reading an extra character. [code]The trace output from this looks like this: 1«1.If I change the php so that it's sending a 1B1 (no special characters) it works ok.I tried using the ASCII version and the Unicode version alt-174 and alt-0187 and both return this extra %2c character.I have tried urlencode from php, but even sending a 1%BB1 provides the same results.I can't fathom why it would all of a sudden start adding extra characters. So should I change my seperation character. If so, what's recommend? If not, should I check every variables from php for this extra character and remove it?
This is a rather advanced problem but apparently I'm not the only one having it.So far I've been using external font loading in all my projects. A Tahoma.swf with a Tahoma Font library item and basically two lines of code:ActionScript Code:import flash.text.Font;Font.registerFont(TahomaSmooth);As soon as I load the font in my application it's ready for use. This is Jesse Freeman's method, in case it looks familiar.The problem is Flash CS4 doesn't embed polish fonts. And clients dnt lke t read tet that hs mssng chrcters. Unfortunately for anyone who isn't english Adobe didn't forsee that people might actually want to specify the character set when embeding Fonts. This strikes me as odd, as supposedly the whole font was supposed to be imported, at least that's how it originally worked, AFAIK.
I am tasked with created a site that handles Japanese characters, and am looking for any insight you can offer for this.My main issue right now is the size spike the site will get if I embed a font like "Arial Unicode MS" with the Kanji character set which has 3174 glyphs. When I compiled an fla with only a textfield and these Japanese characters embed it stands at 731k. So I am looking for options to either eliminate the need to embed the Kanji characters or find a way to limit the number of characters needed to handle the Kanji character set.
1. Which fonts if any come pre-installed on Wins & Mac that natively handle Kanji characters.
2. If there is such a font for Win & Mac does this mean I don't need to embed the Kanji glyphs for the font in a swf, and can be sure any user viewing the site will be able to see the Janji characters, because their OS already can handle displaying Janji characters. For example if I go to a webpage on the internet that has Japanese characters I am able to view the Japanese characters, is this because the browsers themselves have these fonts embedded or is it pulling from my OS to display the Japanese font?
3. If I do need to embed a font to handle the Janji characters do I need to include all 3174 glyphs to cover all possible English equivalents. I read that you can specify a unicode range for a font, believe this only works with CS4 though. I don't know much about unicode ranges let allow the ranges I need for Japanese characters.
So I'm making my own networking protocol for a online game, to save space each message (sent over TCP) is given a ID which is a short, 2 bytes, all messages sent from the server to the client and vice versa are strings, how can I convert a short to a string in java in just 2 bytes (characters)? I want to be able to convert a short int into 2 characters, so that I can send the short over the network in a string format in just 2 bytes and decode it back into a short on the other side (in actionscript 3). A character can hold 256 possible values right? So 256*256=65,536 which is the size of a unsigned short int!
Here's what I've got so far: public static String toCode(int c){ if(c <= 255 ){ return Character.toString((char)c); }else{ return null; }} public static int fromCode(String c){ return ((int)c.charAt(0));//Return the character code of the send string, 1 char only }
This can turn a int into a single character which can be sent over the network, now I just need to have it use 2 characters and it can do up to a short.
How do i open file and get its content as a ByteArray in AS3. I saw examples, using FileStream & File classes from flex.filesystem, but the doc says it's for AIR only.
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 {

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 run into this before, and just ran into it again, and was completely confused how a bytearray converted to a string was only 4 characters long. The problem is, if you EVER try to append a NULL character (not the ActionScript null, but the string value of the char 0), it cuts off the end of the string when printing out in trace or displaying onstage. HOWEVER, if you trace out the length of the string, you get the full length, so the problem arises trying to print the contents onto trace or the stage.
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?

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.
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.
What I'm trying to do is get the total bytes of all the files I want to load and display the percentage loaded of total bytes and bytes loaded of all the files. Its a slideshow so i want all the files loaded and then it will play. I've looked at bulk-loader but it wasn't what I needed. The image are loaded from an xml file. I think I would need to create an Array and then find out the total bytes but I don't know how to reference the loader in the progress.
