I'm trying to read a xml file from client. After search for it. I have got to upload the file to the server with this code.
var imagesFilter:FileFilter = new FileFilter("*.jpg,*.gif,*.png", "*.jpg;*.gif;*.png;*.jpeg");
fileRef.browse([imagesFilter]);
But what I want to do is to read the file from client and parse it without uploading it to the server.
We are trying to create a sqlite db file using java on the server, and encrypt it.Then we send the encrypted db file to a client's pc, which has an Adobe Air desktop app running.The air app then needs to be able to open/read-from the encrypted db file (client is read-only).We are using java 1.6, flex/actionscript 4.5, and Air 3.1.We can create the sqlite db file on the server and send it to the client, and it can be read by the client without issues, when we do not encrypt it.But we are having trouble with the encryption part. We've read quite a lot of documentation about Actionscript's ability to open encrypted sqlite files using AES + CCM (URL...).And we're trying to use java's crypto package to encrypt the sqlite db file.The encryption is important because we don't want the client to be able to open the sqlite db file with any sqlite browser, only with our Air application.

I need to read the uploaded file and parse it. The problem is that in my e.currentTarget.data.toString(); I get only '1' and not the rest of the String. how to successfully read this entire txt file?
question 1:I know I can use:var string = FLfile.read( fileURL);to get the content of a text file, but is there a way to read this text file line by linesuch as:var string1=fileReadLine( fileURL);var string2=fileReadLine( fileURL);question 2:Is there a way to parser(or tokenize) the above string?

We're writing a flash application that can download a MP3 file, convert it to a Sound object, get the raw data and make some processing (like adding sounds, change octaves). After the processing, we want to send the data back to the server in chunks, so the server will be able to glue the data together and recover the new generated file. The problem is: if we send to the server "wav" pieces of sound, we are able to glue them together without any problem in the generated file. However, if we convert each wav piece to a mp3 file (so we can send a smaller file to the server) and join the mp3 files at the server, the result is a sound with some problems at the merge point.
This is how we load the mp3 file from the server:
sourceSnd.load(new URLRequest("sample url to mp3"));
sourceSnd.addEventListener(Event.COMPLETE, carregou);
This is how we convert each piece of mp3 to bytearray and wav:

View 7 Repliesim using an open source program called Festival that generates text to speech, and in ubuntu i call its method text2wave that converts text into a wave file. I am looking into converting short paragraphs to wave files, but the problem is that each wave file ends up being approximately 1.2MB in size. The wave file is recorded at 16khz, and while recording at 8khz halves the size of the wave file (sacrificing sound quality), the wave file is just simply too large. These paragraphs have to be served many times to the clients and our server can not support that much bandwidth. Is it possible to compress the file on the server, and decompress it in my flash script (on the client side) and play the wave?

View 3 RepliesI 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.

View 21 RepliesI've read some books on creating stateless websites, I've read some about stateful client applications, but a lot of complexity comes along when you have to combine both. We have a Flex application that needs to persist data to a database via .NET services. Things to keep in mind are:
- Concurrency (optimistic/pessimistic)
- Performance: Flex needs to load in lots of data so lazy-loading is often necessary.
- Do you use Dto's to transfer data between server and client?
I'll tell you the history of our product. We've used SubSonic from the beginning as a o/r mapper. SubSonic objects are converted to dto's written by us and these dto's are transferred to the client. Clientside the dto's are converted to the domain model. If clientside a domain model object needs to be saved, it is converted back to a dto and send to the server. Server side the dto is converted to a subsonic object and saved to the database.
Now, some time ago, we needed the domain model on the .NET server side... so now we have like three models on the server side, the subsonic model, the dto model and the domain model. The dto model is more simple and resembles the database more, the domain model has much more logic. It gets complex... We now have to synchronize the AS3 domain model code with the C# domain model code. If we could do it again (of get time to refactor) I think we wouldn't use the dto's anymore, but transfer the domain model between client and server. Dto's are simple objects so easy to transfer. Domain model objects can be very complex.
I'm building a Flex application, which is going to perform many server requests (let's say, that almost all interactions require an update from server). At the moment I'm using remote procedure calls for it. But I was wondering if using a socket would be better. In other terms, is maybe better to keep the connection alive rather then performing many calls in sequence? For my demo app I only have 1 client. Is the number of clients connecting to the server a factor for this choice?

This method reads a file from server and then display its content. The file which is getting read is a log file which gets updated at regular interval. The issue is once some content read by AS then it is not getting updated that means after every execution of the function content of src variable below remains same even thou the source file is updated.

I have created a client with Flex Builder which works in a browser but also in an Air windowed application. I must connect it to a server and it has to do asynchronous request related to changing data of the server.Because of the too much expensive cost of LiveCycleDS license, I was looking for other ways, maybe open source and i found the following solutions:
Adobe BlazeDS
Granite Data Services
WebORB Community Edition
I want to ask you which is the easy way to create the solution described above, expecially i want to use J2EE application server type.
As far as In understand the Flex technology, a Flex client connects to a Flex server to retrieve business information. Is this the only allowed connection for the client, back to the originating server? Or can a Flex client also open a secondary connection to a different server wich runs BlazeDS for message exchange?(This might offer an option for load balancing and cross-platform development).
Update: I have found this page which links to the Cross-domain policy file specification:[URL]..
I'm a new grad, so please be kind. I'm working on validating input in a Flex DataGrid cell that the user can edit. The rows in the DataGrid are backed by an mx.collections.ArrayCollection that includes a [Bindable]Model that I wrote. I want to validate against a custom client-side Validator, if-and-only-if that passes I want to validate the input on the server. If client-side validation fails, I want to display the normal validation error (see image below). If server-side validation fails, I want to use the same sort of UI components to notify the user. The solution should not include any external framework (Cairngorm or PureMVC).

How do Flex programmers validate on the server, immediately after the valid client-side validation passes?
I realize it seems silly to search out this "synchronous" design and I hope someone has an answer to solve my problem with best practices. In my defense, the reason I want to validate on the server immediately following client-side validation is so that I'm using Flex's validation framework. If I get an invalid response from the server, I want to leverage the built-in UI components that Flex has to tell the user something is incorrect about his/her input.
A friend of mine has a Flash Action script running on a LAMP server that currently reads an xml config file. He's asked me if it's possible to remove the xml file, and replace it somehow with a system (lets call it an 'auto xml generator') that intercepts the request to read that file and generates an output, so it appears to all intents and purposes as if the file still exists and contains the contents that has actually been returned from our auto xml generator'

View 1 RepliesI have 12 display monitors installed in different floors in a building. These monitors display announcements that will be update once in a day. I'm retrieving these announcements from db and storing in an array and displaying it all day long. In addition to this, I have a requirement to display emergency alert messages on the monitors. My Server is a windows 2000 server. I'm using asp for creating the JSON object.
For the emergency alert I am thinking of doing this:
Create a page in asp that lets user to enter emergency msg and save to db.
Create a page in asp that will check if there an emergency msg in db and show it in a asp page in json.
Create a timer that pings this json page every 1 second. If it's available then show it.
Is there any other sophisticated method available to poll the server or to send messages from server to client?
