View 3 RepliesI would like to be able to operate a scanner from my AIR application. Since there's no support for this natively, I'm trying to use the NativeProcess class to start a jar file that can run the scanner. The Java code is using the JTwain library to operate the scanner. The Java application runs fine by itself, and the AIR application can start and communicate with the Java application. The problem seems to be that any time I attempt to use a function from JTwain (which relies on the JTwain.dll), the application dies IF AIR STARTED IT.[code]
View 2 RepliesI've been trying to use ffmpeg with an air app that I made in flash cs5.5. I have it so that ffmpeg.exe needs to be located in the directory where the air app is installed (File.applicationDirectory.nativePath). For some reason this only works when I run the program through the flash dev environment. But when I actually deploy the app, I get error #3219:The NativeProcess could not be started. ffmpeg.exe is located in the same folder.
I actually don't know the full message that it gives...not sure what the property of the error that will give me that message when I catch it. All I know is that it's error 3219. Would this be a profile issue? If i didn't have the extended desktop desktop profile, I don't think I would be able to get this error, I'd get a profiling error wouldn't I? I've disabled user access control as well...I'm using windows 7.
I have to implement AEC in Flex video conferencing application. I know that it can not be done directly in Flash. I'm thinking to write a native application or library that will do AEC outside Flex.
As far I know Adobe Connect Pro is using some external library that do AEC. I'd like to follow this direction and do something similiar.
There comes two possibilities in my mind:
1) Independend custom AEC filter.
The custom AEC filter will be run in the background and will be processing all data from microphone and sound card and doing AEC. The echo signal will be the data that is to be played but delayed in a temporary buffer, something like this: aec(input, delayed_input, output).
I don't know if it work, because Flash microphone input doesn't know about my custom input and the same with the speakers. But how it is done in WinXP/Vista that have AEC at the system level?
2) AEC filter interacting with Flex's NativeProcess.
The filter will be run by NativeProcess. Flex app will pass microphone sound, received remote voice to the filter and return voice with echo removed and then Flex will output this to the speakers. Will it be correct?
If the 2) method is OK then I have following questions:
I will start with Speex's AEC so in what format should be the data pased from Flex? If I choose Flex Speex codec for sound compression can I pass it directly to the speex library? Will be the performance OK? Calling NativeProcess library every sound frame buffer can be time consuming I think. Why there is no AEC implementation in AS3 that can be used directly from Flash? As far I know to do AEC you must have echo data and microphone data (in Flash 10 there is direct access to the microphone). There is definetly something that is stopping doing it like this but I don't know what it is yet :) Is there some free AEC implementation or a DSP library with in except Speex's that I can use?
I realize this is probably a simple question but my google-fu is failing me. I would like to get a windows explorer like file browser to popup when I click a button to select images to upload to my AIR application.However I cannot find a component that handles File exploring. Does anyone know what to use?
View 1 RepliesIt could run a native process in an adobe air application by enable extendedDesktop.
But if create an flex library, does it support running an native process. If yes, how to configure it?
I have a Flex AIR2 application which uses native process to run CMD.exe. Application running fine on WinXP, Win R 2008 server. But not running on VISTA 64 bit OS. Flex not able to run CMD.exe when application installed in C:Program Files (x86). When I run application as Administrator mode it is working fine. Below is my code, I want to start cmd.exe as Administrator.

I've found several examples and documentation that show how to read and write files on the system, but all show user intervention or reading/writing files in user profile directories. There are a few things I want to do:
Monitor system and other application log files for changes, then automatically load those files when changes occur Reload a previously open file when the application launches Write files into a log directory, which probably will not exist in the same path as the application.
In my very quick search, it seems that there may be a security model that constrains an AIR application's access to the file system, so that files can only be read or written to directories selected by the user with the file system dialog OR files can be written within the user profile or air application directory.
Does an Adobe Air application have unconstrained access to the file system?
I'm trying to access local file system from Flex web application. I know it is pretty difficult, but I think there must be a way. Is there a way that Flex app can use AIR components or maybe web application can call some AIR module in order to choose files and upload?

I am trying to develop an android extension for air, but I have a problem with resources.According to this : Official adobe doc - FREContext and this Extending AIR by Oliver Goldman We simply have to add the resources we need in the res file of the Native part, then they are added inside the .ane file and passed to the final apk. In order to access them though we have to use getResourceId( "drawable.background_image" ) instead of R.drawable.background_image
But when I generate my extension, the res file is actually not even included anywhere inside the .ane file and also not inside the final apk. And I have found not a single extension on the net using resources (not even in the adobe samples)For this test I simply use the basic Hello world Vibrate test, but I added a new png in the drawable folder.As you can see while unziping the .ane file, then going to META-INF/ANE/Android-ARM the res file is absent.As a result, the program crashes when I try to access my resource FREContext.getResourceId("drawable.ppy_accessory_manage.png")
PS, here is my batch to compile the ANE :

set root_directory=C:UsershugoAdobe Flash Builder 4.6
set library_directory=%root_directory%HelloANELibrary

I cannot afford the Creative Suite or Flex Builder but I would like to develop a commercial Flex/ActionScript AIR application. Is this a viable goal and are there robust tools out there that don't cost a small fortune?
View 2 RepliesI have a requirement to print a bill from the AIR application.
Following are the constraints.
I need to print to a DotMatrix Printer. I have a complex layout with header, footer and a datagrid with data rolling out to more that one page. I need to have a template to which I will be passing my object.The suffice with the usage of Jasper reports, but I have no server side support.I tried the FlexReport, bentbit and other tools which is optimized for the DotMatrix printers.
Is there a alternative to get the above requirements done. Is there any alternative similar to that of jasper reports without going for a server.
I am trying to make an AIR application, that needs to pass an image (.jpg/.png) to a C++ app, that does number crunching.(this needs to be done very often, like every 2-3 seconds.) I've managed to pass the image by saving it to disk via AIR, then opening this file with the C++ program (and passing the filename as an argument to the C++ program), but this method is really slow, because it involves lots of disk I/O.
Is there a method to send an image directly to a native process?
Edit: There is a good Flash-C++ communication example at [URL] using sockets. The big problem with this method is, that some firewall settings can block the communication (i get a windows firewall warning, when i start the app).
I see a lot of tutorials out there for the flex environment but none for Adobe Flash Cs5. Not even when it is using the AIR build.How exactly does one communicate with a native process using flash or air?

View 1 RepliesWhat is the best solution for multi threading in flex, I notice if I play a mp3 in flex and do something else at the same time something ends up giving out, either the song stops playing or the UI hangs for about a split second. It doesn't have that fluid response that I am looking to achieve. If possible I would like to call a multi threaded java class to do some of the client-side end back end processing. I just don't know if that is possible.
View 6 RepliesIt seems that AIR doesn't come packaged with the powerful FTS module for Sqlite (its a hot requested feature)
What are the some other alternatives I can use? I want to be able to do simple boolean and phrase queries. Support for stemming would be great but not required. I am targeting the mobile platforms.
So far I've thought of three options:
Write a simple inverted index and a scorer Do search on server side (last resort b/c it messes up offline capability) Somehow install FTS module with AIR. First indication from googling is that its not feasible (looks like loading of modules is disabled in air)
Does anyone know if adobe flash player cache data is available to other users on a system? For example: A user logs onto Windows XP, then uses my adobe flex application... and in the process of doing so downloads the signed flex lib... He then decides to mow the lawn and log off. At about 3pm the same day, his Mum can't hear the TV over the sound of the mower, so she decides to log in using a different XP user account. She proceeds to use the very same flex application. Does she also need to download the flex lib again, or would the data already be cached in the flash player?

I need to know what the details are of the file permissions of an adobe AIR app. Specifically, to where can may it write text files? Anywhere on the local system? I heard Adobe has a set of "Sandbox Permissions" but these just confuse me as I don't know where they apply. Additionally I wish to know if you need some kind of special permission to append to a file somewhere on the system.
View 1 RepliesI'm going to write an application with the Air/Flex-Framework. I'm looking for Best Practise and general Design Patterns for designing software especially in Air/Flex. I have experience with this framework but never had the pleasure to write a piece of software from scratch.

I'm familiar with general design patterns by gamma. I'm looking more for advise in designing good quality software with Adobe Air/Flex.

View 1 RepliesCurrently I am building an application that launches crtmpd (a rtmp server written in C++).
Whenever I launch the application from within Flash Builder it works great, if I install a release build from an air file the process.start() returns a generic "could not start process" error.
The crtmpserver.exe is stored in applicationDirectory and the config file is kept in applicationStorageDirectoy.
So I've moved it to the native storage directory. But the problem persists. I've found the following though:
startupInfo = new NativeProcessStartupInfo();
startupInfo.executable = binFile;
processArgs = new Vector.<String>();
processArgs.push(luaFile.nativePath);
startupInfo.arguments = processArgs;
In the IDE after this startupInfo is setup correctly. On client machines all properties of startupInfo are still null.
I recently came to know about the adobe flash builder with flex in latest release it supports to achieve the benefits of flash for iOS apps.As i am looking for a calendar based app,before taking the Adobe flash builder as a solution, i would like to be clear on the following queries.
What limitation is there of the ipa file generated from FB 4.5 as opposed to a core COCOA touch based solution What are the performance differences between the FlashBuilder app and natively built iPhone app. Is there any limitation of building a HTML5 based app given the calendar functionality apart from look and Feel.
