I have a json file on my server.[URL].. If I type the url into a browser I get a page not found error.
If I set the url of a http service to the path of the json file the httpservice wont load it.
Is it possible to load a json file in this way or does the json file have to be the result of a server page request eg: [URL]..
In a very simple first AIR application (I'm using Flash Builder 4.5), I am trying to accomplish the following on my MacBook:
Read a local file (JSON format) into the AIR app. Parse through the file. Display some selected contents in a grid.
That's it.
I've found an example that does some simple JSON parsing in Flex, but the problem is that it loads the JSON source from a remote web site.
So do I need to load any file-specific libraries to make this work in AIR? Or can I simply refer to the file by using the Mac file-path? I just want the local file to be the JSON source. The parsing is already taken care of.
Created an editable flex grid which exposes a method called getGridData() to javascript. I am using the JSON.encode() method of the [url]....library to convert the grid object's dataProvider into JSON before returning it.
ExternalInterface.addCallback("getGridData", getGridData);
public function getGridData():String
{[code].....
However, when I sort a column in the user interface, the encode method is failing throwing the following error
Property usingCustomCompareFunction not found on mx.collections.SortField and there is no default value.
I'm using Flex 4 for building the communication to Arduino. There are three (3) main values coming from it (X,Y,Z). Here the Flex's code
newText.text = magnetic.readUTFBytes(magnetic.bytesAvailable);
d = JSON.decode(newText.text);
MNx = d["x"];
MNy = d["y"];
MNz = d["z"];
Is there any example or codes (in Flex) that can I create and save these values as a TXT file (data.txt). These values as a structure should be like below.

I need to parse a large trace file (up to 200-300 MB) in a Flex application. I started using JSON instead of XML hoping to avoid these problems, but it did not help much. When the file is bigger than 50MB, JSON decoder can't handle it (I am using the as3corelib).
Try to split the file: I would really like to avoid this; I don't want to change the current format of the trace files and, in addition, it would be very uncomfortable to handle.Use a database: I was thinking of writing the trace into a SQLite database and then reading from there, but that would force me to modify the program that creates the trace file.
So I've tried to build a small utility to view the contents of a JSON file in an easy-to-understand manner (for non-tech people).I have Googled far and wide, high and low, but every example that shows how to consume a JSON file in Flash Builder uses the HTTP service, pointing to a file on the web.Here I am, sitting in front of my MacBook, wondering why I can't make this work. In the documentation I've found (sort of relating to this issue), they always show Windows examples, and they seem to work fine:That doesn't work. I've tried some "resolve to path" syntax, but the HTTP service does not seem to allow for anything but file paths in quotes.

Can I load external SWF files using Javascript sequentially? Or does it have to be in Flash to load the SWF files from XML?
Currently we have SWF banners (900 x 230) loaded from XML sequentially and it works fine, but it is killing our computers. I wonder if the javascript will run the SWF banners smoothly?
I'm working on a Flash AS2 application that needs to post JSON data to a web service.In previous projects, I've used LoadVars.send() or LoadVars.sendAndLoad() successfully to manage this:

var response_lv:LoadVars = new LoadVars();
response_lv.onData = function(rawdata) {

ActionScript Code: import com.adobe.serialization.json.JSON /*Path to the JSON class (in JSON.as). NOTE: make sure to keep all the classes in the original json folder together and that at the very beginning of each class file in the json folder, the file path after the word 'package' accurately reflects that path to the FOLDER in which all the classes are located. E.g. package [URL]

I'm writing an AIR app that reads from, and writes to a local JSON file. I'm using the File and FileStream classes. It works perfectly on Mac, but on Win7 it's not saving. Does anyone know of any platform-specific issues or tips for the .writeUTFBytes() method?
file = new File(itemBase + "/manifest.json");
fileStream = new FileStream();
fileStream.open(file, FileMode.UPDATE);
fileStream.writeUTFBytes(json);

View 1 RepliesI'm currently working on a project that contains a lot of data, about 14.000 records. This means an xml file of about 3mb. Now my question is: Should I use the xml file to load all the data at once, or should I use a webservice, that provides the data when I need it? Keep in mind that I'm new to webservices. And if I'm going to use a webservice: How do I store the data, in a mySQL database?How fast is a webservice?
View 1 RepliesIn an asc file, I am trying to retrieve some data from a server that uses JSON as its exchange format each time someone connects to a specific application.

The target object from the sendAndLoad method seems to be empty .he response format from the server is like this :{"result":{"uid":"24947431041778945007157724608309","sid":"20825068196 030559827758762683967"} (I got it by doing a POST with cURL)ince the data doesn't have the attribute=value&attribute2=value2..."format, I think I will not be able to get themoes anyone know if it is possible to first get and then parse these data using either ServerSide ActionScript's API

I'm using Flex 4. Have PHP backend and mysql database with one table consisting of multiple rows. I take the raw data from the result event and decode it using JSON. I then dump the data into an ArrayCollection that I use as my datagrid's data provider.
My question is how can I tell when someone inserts a new row into the mysql table so that I can automatically refresh my ArrayCollection, thus seamlessly updating my datagrid one element at a time? Right now, it's just a one time call and the connection is closed. If someone inserts a new row into the database my program doesn't recognize, unless I restart it. I'd like to auto-update the AC whenever a single new row is inserted into the mysql database. Is there a way I can "listen" for this change?
