Actionscript 3 :: Restrict Plugin Access To File System And Network
Feb 14, 2011
In a plugin context (a swf loaded by an another swf), is there any way to restrict access to file system and network in the same time to the loaded swf?Compiler option "-use-network=true|false" does not fit because you cannot restrict both file/network.[code]The loaded swf is in user's document folder, outside Air app folder. Currently, the loaded swf is abble to load "c:/Windows/regedit.exe" and I don't want it (neither sending informations on the network).

im testing out some AS3 and working on my first preloader. Ive run into the file access problem and looked about for a while and found that locally I can get files to load with the compiler flag -network=off. To put this online would I have to do a compile with the network on but with a Security.allowDomain("myDomain") line. Would this then work online so long as all the required files are in the same place.

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?

Yes, you can access Local File System in Flex and that too with a standard SWF without resorting to Adobe Air.Check out the link below for full details and the SWF.

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 got a textfile who i am reading on a serverside script and passing it as a script to my client side as3 code. The problem is that i am using characters like ä,ö,ü,ß and this isn't well displayed. I tried System.useCodePage but the compiler complains about : 1120: Access of undefined property 'System'. It doesnt matter if I tried this on the first line of the 'Action' in the first scene or in the first line of the first .as file i am loading. (btw i am only working with .as file and not in the timeline). When i am importing flash.System.* the compiler complains he dont know useCodePage.

My flash movie loads config.xml from the file system. Inside config.xml are urls and the base url to other xml files that I wish to load in to the flash movie.
These urls in config.xml are requested by the flash movie providing my flash movie with data. Again these are .xml files how ever they are being accessed using the network. EG " http domain dot com slash data dot xml"(i cant post links yet)
I know that I cant access both network and local files in the same movie so my question is this. What is the best way to pass in the base url dynamically to the flash movie so i can cut out config.xml?

I've got a Flash Banner worked with AS3.0. It loads XML and then load the Jpegs. At the beginning, the SWF accesses the files under the same directory. So the code goes like

We're planning on allowing others to embed our custom player swf (which play the projects we produce) on their site/blog/etc with embed code, but want to maintain enough control to blacklist certain sites that use our projects unfairly or in violation of our terms.What's the best way to block certain sites from embedding our swf? We had an idea of attaching a unique ID with each embed code and then having the player make a call to our site to check a list to see if that ID is blocked or not....but that's easy to bypass, and wouldn't it be easier to just dump the blocked sites into an .htaccess of httpd.conf file with some mod_rewrite trickery?

The reason Ordinarily I would just host everything on the server, the swf file and images and serve them out using something like apache. However, we're working with an embedded device with hardware limitations. So we thought we could avoid this by hosting the images locally on a cd.But Flash player moans about the security settings. I know a way to overcome this would be to give the user instructions to change the global security settings- hence allowing both network and local access. But we feel that this would be too much to expect the end user to do.We want our model to work out of the box so to speak. Or as best as possible.

Is it possible to access both network and local files, flash player 9/10?
Here is the situation:
I have an SWF which runs locally on the client's machine.
It communicates, via XML socket, to a C++ server.
It also needs to read some configuration files from the local file system...
c:config.xml <---> test.swf <---> C++ server
So I need the SWF to be fully trusted, as if it was ran from the Flash IDE.But I can't tell my clients to set it to be fully trusted using Adobe's Global Security Settings Panel
What I can do is alter my C++ server code, somehow granting permissions to the SWF.

I have vod files that need to be restricted to only the IP range of the ISP service. The live streaming can be available to all, how do I restrict vod access in the FMS Interactive Server, is it in the following?Virtual host on Interactive Sever:
[URL]
Would I edit these files for that restriction, how do I put the IP range in format wise?
/opt/adobe/fms/applications/vod
allowedSWFdomains.txt
allowedHTMLdomains.txt
Would I add the IP range in this files for each virtual host, I have 3 of them?
/opt/adobe/fms/webroot/vod
I do not want to impact the ability to view live streams, it will need to remain open.

I have the following scenario:
One application JEE / Flex 4 running on a tomcat, inside my Flex layer I have a iFrame passing a url to an ip of my internal network (http:url....) which is another application running within an industrial PLC.When access this app from within my internal network works fine, but when I try to access this iFrame to an external network in my home for example have a timeout error onhttp:[url].........
I believe this error occurs because the flex client is trying to run this url as I was in a internal network.Is there any way to run this url from an external network?

an answer here opening swf files using WebKit framework says the following about running SWF movies inside WebView inside Cocoa application: "because the Flash plug-in is not garbage-collection supported, the plug-in won't work if your application uses garbage collection".
Meanwhile, an answer here Flash AS3 animation in Mac vs Windows discusses Flash garbage collection on Mac (likely in Safari) and says that it sucks but it does exist.
So is the first claim about no garbage collection in WebView false or is the WebView plugin distinct from Safari plugin?

i have a question that is almost like other questions but with a small but very important difference. how can i restrict file types for user with a popup showed in the browser.
The standard file input of html can limit that with a command but it does not work in all browser so it is not an option. I do not want to validate the file extension after the user has chosen a file but before that, when he is choosing.[URL].. but it uploads the file after the user has chosen it, i do not want to do that, i want to upload it after the user submits the form.
So the problem looks like this that there are some ways of not letting the user send a not valid file but they are not good because, one is that i validate after the user have chosen the file and the other is that i upload the file before the user submits the form.
I just want a simple thing to not letting to "chose" a not valid file, it does not matter if it will be made with java script or flash, just let it work.

StackOverflow community,[URL].. used to launch AIR applications from Flex applications requires the use of an air.swf file located here:[URL].. We have tried to download this SWF and use it in our internal network, but it is not working, we depend on using the one located in the Adobe site.
Is there anyway to use this air.swf file without having to access the Adobe site?

Can we use or access shared object stored in another system? I'm storing some data in shared object in one system can I access that shared object data from another system? I think Shared objects are stored in local machine. Can we give the path to (specified system i.e., server) where the shared objects will store, and can we access that object through same path?

I am trying to publish a flash file onto a website but once I post it there it keeps looping. How do I get it so that it doesn't loop? I have a feeling it's a setting in Flash that I have to find before I publish it but I don't know where it would be or if there even is one.

When I copy the adress into the browser the jpg-file ist displayed corretly.

I monitor (and log to server) most user errors in our flash game. Quite frequently I see security errors related to trying to make requests to a cross-domain URL (usually the Facebook Graph API). 99% of our players can make these graph API calls with no issues.What I think is going on is that the client makes a request, but fails to load the crossdomain.xml file. I don't quite know how AS3 handles this in the case of a failure to load the crossdomain policy file...will it retry for every URLRequest made until it succeeds in loading it, or does it just give up forever?

Currently, I do serialize my model object to the SharedObject instance:
try {
var mySo:SharedObject = SharedObject.getLocal("sig");
mySo.clear();[code]....
Likewise, I load the saved model using the SharedObject instance. Works great.Ultimately, I'd like to serialize it to a file - which fails. Here is how:
var fp: File = File.applicationStorageDirectory;
fp = fp.resolvePath( PREFS_FILENAME );
var _prefsStream:FileStream;[code]....
The complementing read operation suddenly breaks and reports missing bytes.In fact, I can't image how FileStream / _model.writeExternal() is able to serialize, since it needs to somehow know, that a new serialization operation is about to start. If it doesn't know, it won't be able to determine, which object instances are left to serialize.Thus, I image that my concept is completely wrong or I missed how to initialize the serialization operation.I'd be happy to read the raw ByteArray from the shared object and write it to a file. Unfortunately, I didn't find a method to retrieve from a SharedObject a ByteArray of a certain property, in my case mySo.data.model.My question is loosely related to this one: Why does delete( DictionaryInstance[ key ] ); fail?

I am developing a ASP.NET web site where users will need to be able to create their own business cards. So, I'm looking for a tool (most likely Flash) that I can easily integrate into a web site and lets users add text and custom images to their cards and then create an image and/or PDF from their work.
is there a plugin that does this?

I am creating a web page that allows users to upload their own swf files to my web page, which are then used by the main web page as components. This creates a security issue though because I don't want the uploaded swf files to access other files on the server.
when the main webpage starts, it loads whatever third party swf files the user specifies. Is there a way for my main web page to change the security settings of the loaded swf so that the loaded swf is treated like it was loaded from another domain? Or is there another way I can provent these uploaded swfs from accessing local files on the server.

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.
