View 1 RepliesWe 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.
View 1 RepliesI want to create an application that has these features
- At client side: Display a list of images, when user click on one image, data will be stored in MySQL database.
- At server side: Manage images used in client side, I can delete, add new images.
Is this possible for me to achieve this using Flex? And if it is able, will my output be 2 separate SWF files? And where can I find the materials to read on writing such applications?
User interacts with Adobe flex webpage to configure reports based on some data stored server side. They configure their view and have THAT view emailed to them daily. I've got the report builder, the part I'm trying to figure out is how to render the report server side and send it out as email (native flex functionality? convert to html? take screenshot? assume something is running client side?...)

load a client side xml file from a web based flash.
Basically the project is as follows. Each station will have a specific xml file describing its contents and the flash file will be displayed from a browser that will read the xml file for display.
How can I get file size at client side using actionscript and javascript.
View 3 RepliesAny tips or methods(encryption, plugins etc) to load flash files (i.e. swf) as quickly as possible at the client side? consider files size is between 5MB - 10MB....

View 3 RepliesI'm rather inexperienced with flash and as3, and I've been given a task of writing a program that downloads images from URLs that are provided, and saves them to a specified location on the user's computer.
The idea is to be able to download multiple images (user selects them) and download them all to a single directory (which the user selects first) so that he doesn't have to download them one by one. Also, putting them in an archive and downloading as one file wasn't an option.The only solution I found is using FileReference.save(), which won't work for me because it opens a save dialog.
Basically I'll be working with large XML files (approx. 20 - 50 MB). These files needs to be uploaded on a server.I know it isn't possible to touch the files with javascript, nor to implement HTTP compression on the client-side.
My question is that if any solution exists (flash / action script) that compresses a file and has a javascript API? The scenario is this:
Trying to upload 50 MB XML file Before upload a grab it with Javascript and send it to the compressor.Upload the compressed file instead of the original one.
I'm looking for multiple file upload component with alternative ways.I need HTML5, Flash and normal upload support, depended by device.I don't like FancyUpload, because it uses mootools and mootools is very big library.Also I can't use jQuery, because I'm writing on Ext js and it's not good idea to use two big library like jQuery and Ext js.
View 2 RepliesI would like to know whether is it possible that Actionscript play .wav files that are stored on the client side? If yes, how? Otherwise, what are the alternatives to enable playback of wave files on the user's computer? I plan to create a button that will playback pre-recorded speech(mp3 format stored in the server) as well as user recorded speech (.wav format stored on the client side after user recorded the speech). How can I do so? I would want to make it away that it appears like a Q&A conversation session between the computer (mp3) and user (recorded wave).

Since I'm developing a multiplayer card game for Facebook using Flex as client side and Java SE as server side, I wanted to know how do I actually make the connection between Flex and Java? the server and client should be able to send each other data(cards,movement,room information etc...) across and I wonder what's the easiest way to do it without complicating it. where to read about it ? I know JAVA but I find JavaEE hard to understand.
View 2 RepliesI have an upload form for an image. The user clicks browse and selects a file. How can I get the image dimensions the moment the user selects the file (before the file is even uploaded to the server). It obviously has to be something client-side with maybe javascript/jquery or flash/flex (prefer js//jquery though), but can either of them do this? This is the code I'm using to tie into zozo's getImgSize() function, but it gives me 0*0 as size.

im 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 1 RepliesI'm creating some image uploader in Flex with client-side image processing. Processing consists of two steps:
1. Resizing (solved)
2. Converting resized image (represented by ByteArray in PNG32 with alpha-channel) to gray-scale PNG with bit-depth = 2 and no color-palette. Is there any existing library that is capable of second step? Something like libpng for C++, maybe?Edit:It seem I stumbled upon rarely encountered problem. However my descision was to create an AS3 class that is capable of converting bitmapData to 2bit grayscale PNG. I used standart PNGEncoder and PNG format specification (which is not so good as I expected) as basis.
I am making an app where people upload a bunch of images and it thumbnails them and saves them to the server. Is it better to create thumbnails from the uploaded images, or to upload them to the server then re-download the thumbnails?

Using RecursiveDirectoryIterator of PHP i am able to create directory tree and can even flatten it using RecursiveIteratorIterator class , but I want to create directory tree structure which TREE component of flex understands . The following is an array structure in php which flex understands.
array('label'=>'rootDirectory','children'=>array(array('label'=>'subFolder1','children'=>array(array('label'=>'file.jpg'))),array('label'=>'EmtptyFolder','children'=>array())));
create the whole directory structure at server side into the above array format.
