I tried on Flex 3, facing issue with uploading JPG/PNG image, trace readUTFBytes would return correct bytes length but tmpFileContent is trucated, it would only appear to have upload just 3 characters of data to the server through PHP script which made image unusable.I have no issue for non-images format. What is wrong here?

I'm extending XMLSocket to work with a daemon, written in Java, that a peer is using to interface with his PLC controller.What I should be seeing from the daemon is simple digital io info in the form:
Code:
d0i,d0o,
Which represents a 'button' dowm/up. The strings are terminated with commas to make it easier for me to parse them. I've got my XMLSocket working just fine, but I'm receiving the data more like this:
Code:
socketDataHandler:
socketDataHandler: D
socketDataHandler: 4
[code]....
So, there's a null character, followed by individual chars that make up the message I'm expecting, only last "," is truncated. It does come through on the next dataEvent:
Code:
socketDataHandler: ,
socketDataHandler: D;
socketDataHandler: 4;
socketDataHandler: O;
Lastly, I checked raw data in a shell, and it looks like:
Code:
0000000: 0044 0034 0049 002c 0044 0034 004f 002c
0000010: 0044 0034 0049 002c 0044 0034 004f 002c
When dumped to hex. It is my understanding (mostly from a sdocs) that Each XML message is a complete XML document, terminated by a zero (0) byte.I can see that he's sending each CHAR separated by a 00 byte, but they are prepended, not appended like:
Code:
0000000: 44 00 34 00 49 00 2c 00 44 00 34 00 4f 00 2c 00
0000010: 44 00 34 00 49 00 2c 00 44 00 34 00 4f 00 2c 00
or even better:
Code:
0000000: 44 34 49 2c 44 34 4f 2c 00
0000010: 44 34 49 2c 44 34 4f 2c 00
Is there an easy way to get the byte length of a string in AS3? String.length works in many cases, but breaks if it encounters mulibyte unicode characters.(in this particular case, I need to know this so I can preface messages sent across a TCP socket with the message length. This is in standard netstring format e.g. "length:message,").
View 1 RepliesI'm trying to serialize and deserialize a byte array to a string using Base64 for as3.
Here is my code
public function Serialize(vector:Vector.<Action>):String
{
var bytes:ByteArray = new ByteArray();
var serialized:String = "";
[Code].....
is the error I get after calling deserializedObj = deserialized.readObject(); Should I be get that error if I'm just trying to put this into an object? I'm not trying to put it into an action class object yet, but if it is then the action it's getting doesn't have parameters that were originally inside.

View 1 RepliesI am working on my open source project Downloadify, and up until now it simply handles returning Strings in response to ExternalInterface.call commands.
I am trying to put together a test case using JSZip and Downloadify together, the end result being that a Zip file is created dynamically in the browser, then saved to the disk using FileReference.save. However, this is my problem:
The JSZip library can return either a base64 encoded string of the Zip, or the raw byte string. The problem is, if I return that byte string in response to the ExternalInterface.call command, I get this error:
Error #1085: The element type "string" must be terminated by the matching end-tag "</string>"
ActionScript 3:
var theData:* = ExternalInterface.call('Downloadify.getTextForSave',queue_name);
Where queue_name is just a string used to identify the correct instance in JS.
JavaScript:
var zip = new JSZip();
zip.add("test.txt", "Hello world!
");
var content = zip.generate(true);
return content;
If I instead return a normal string instead of the byte string, the call works correctly.I would like to avoid using base64 as I would have to include a base64 decoder in my swf which will increase its size.
Finally: I am not looking for a AS3 Zip generator. It is imperative to my project to have that part run in JavaScript

View 1 RepliesI am currently developing an application with a Flashlite frontend which communicates with a C# server. The C# server access a database to retrieve images (stored as byte[]) and feed them to the frontend. The thing is, im using XMLSockets so I tried to convert the byte array into a string which left me with something like "23659256239786107089710981890776178910976". I then send it over to the Flash lite, but how to turn this into an image. I am currently using Flash Lite 3.0 /AS 2.1

View 2 RepliesI have been programming using flex 4 on adobe flesh builder 4 in order to create a website. The site require a connection to java and hence I decided on using blazeDS, in order to do so I updated the flex project's properties and set the flex server from "noneother" to "j2ee" as is required for the use of blazeDs. Ever since this change the site no longer runs as it should, as all the images are not being displayed and all action listeners are no longer working.(The problem is due to the flex server as when I changed it back to none the site worked fine)I need the j2ee server, and cant go by without it.

I'm using Flex 4.5 in a Mobile air for android application. So, Using the Camera/Camera roll [URL]I want to do a simple upload using amfphp Note: Since this is how you get pictures on devices, i cant use the filreference because it wants you to get the pictures using "browse" which cant be done on android or ios My plan is, after I select a picture or capture one with the camera, in the event I can get the local url to the picture that was taken like this:
[URL]
I'm putting this in the imageURL var (i'm assuming i should make it into a byte array to transfer it, im not exactly sure this is my first time making something like this)Here's how i'm taking that image, making it into a byte array, and using amfphp to send the upload to the server:
protected function upload_btn_clickHandler(event:MouseEvent):void
{
var request:URLRequest = new URLRequest(imageURL);
var urlLoader:URLLoader = new URLLoader(request);
[code]....
But i'm getting an error NetConnection.Call.BadVersion.This is the first time im trying something like this so im not even really sure if im going about it right. All the examples I find online go about using the fileReference class, but that seems to require me to use the "browse" method, and im on a mobile application that uses the camera and camera roll to grab pictures off the device, and im not sure how to incorporate that into the fileref class. I figured i could just get the byte array and send it to php myself and it should be just fine.

Each corresponds to a different color of "Monster" class I reated. "GreenMonster", "BlueMonster", etc. are all custom classes. Each class has a string property called "MonsterColor". So "Blue1.MonsterColor = "Blue".
To save lines of code, and learn, I'm trying to use a local string variable to take the place of whichever of these 6 int variables I need. So inside a for loop, I've created a variable called "colorscore".
