How do I convert a 64-bit number to a byte arrray in Flex/Flash? Still fairly new to flex so... Tell me there is a better way to do it than this:
//Some Int64 value
var n:Number = 256 * 256 * 256 * 256 * 256;
//256 ^ 4 not working in AS?

View 1 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:
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 .

We have requirement with the AIR application which loads the flex generated swf which inturn loads the flash generated swf using SWFLoader. This is not working as desired.This gives the following error: SecurityError: Error #3226: Cannot import a SWF file when LoaderContext.allowCodeImport is false.

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 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?
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.

View 5 RepliesI am trying to display a bytearray as a resized image. The Image is displaying correctly, but the sizing is off. Let me explain.
First I have the image data encoded so I need to decode the image data
// Instantiate decoder
var decoder:Base64Decoder = new Base64Decoder();
// Decode image data
[Code]....
This works. The image is displayed correctly. However, if I hardcode the image (img) height the resized image is shown correctly, but within a box with the original image's dimensions.
For example, if the original image has a height of 300px and a width of 200px and the img.height property is set to 75; the resized image with height of 75 is shown correctly. But the resized image is shown in the upper left corner of the img container that is still set to a height of 300px and a width of 200px. Why does it do that? And what is the fix?
The best way to illustrate the problem is by placing the image inside a VBox and show the borders of the VBox. From the code block above, if I change the image height and set the image to maintain aspect ratio (which by default is set to true but I add it here for completeness). the problem becomes clear.
// Display image
var img:Image = new Image();
img.height = 75; // Hardcode image height (thumbnail)
img.maintainAspectRatio = true;

I am using Flex's Alchemy library to generate SWC's out of C files. I have a byte array (unsigned char buffer[size]) in the c-layer that I'd like to return to the ActionScript layer as a ByteArray. Do I have to iterate through the array and explicitly call AS3_Set on each element or is there a way to just return the entire C array at once?

The Sound Object plays back fine & at full length, but the float Array i get from it is cut off (but sounds correct), so i must be doing something wrong in the conversion:[code]The top two channels are the original Sound Object.The lower two is the float Array Data. I aligned them so you can see that the beginning is cut off and obviously the length is incorrect.

I want to open a pdf/excel/doc using flex, as all know we can use navigateToUrl(URL) method to open a file from the server. But my problem is those files are encrypted in the server, so I load the files as follows
ByteLoader = new URLLoader();
ByteLoader.dataFormat = URLLoaderDataFormat.BINARY;
ByteLoader.load(new URLRequest (constructedURL));
so that I can manipulate them and can get the decrypted file. Now my question is, my data already got downloaded from the server, so how will I launch the files(pdf/doc/excel) with the binary content which I had got?
Is there anyway i can launch those files like we do it in navigateToURL()?
