Flex :: Check Remote File Availability With AIR?
Aug 24, 2010I was wondering if there's a remote file availability check using Flex-AIR. Not a local file.
Example: For displaying a image place holder instead of a broken image icon.

View 1 RepliesI am trying to upload the files to the remote server using PHP with Flex interface. If it's not localhost, it shows the security error. I have already put the crossdomain.xml in the tomcat web app root directory to allow all the domains. However, the security error is still shown when I tried to upload the file.
View 1 RepliesI need to figure out the size of a remote file before I download it.And I know that in local place this can be done as follows
var _filePath:String = "X:/save/abc.exe";
var file:File = new File(_filePath);
if (file.size > 1000)
[code]....
But when I tried a remote file like
var _filePath:String = "http://www.aaa.com/webfile.exe";
It didn't work.And how can I get the size of a remote file before I use
var _downLoadPath:String = "http://www.aaa.com/webfile.exe";
I'd like my users to be able to easily navigate their files, which live on my server. Is there an obvious / built in way to build the front end for this in Flex? My ideal scenario would be to have something that looks like the local file browser - but I'm pretty sure that's not an option (although I'd love to be wrong)

I am building a Flex application with ActionScript 3. Unfortunately I've hit a wall with this one...I would like to be able to apply an upSkin to my dynamically generated button like this:
//this theSkin variable is dynamic in my app, but for this example it's a simple string
var theSkin:String = "http://www.mypicturedomain.com/images/myimage.gif";
var navBtn:Button = new Button();
navBtn.id = "thumb1";
[code]....
When I attempt this, I get this error:
TypeError: Error #1034: Type Coercion failed: cannot convert flash.display::Loader@3dac941 to Class.
How do I skin this button with my image dynamically? A couple of things to consider:The upSkin image must be remote. It can't be local.The button must be generated dynamically (it's in a for loop).

View 1 RepliesI tried with flex and java in the backend. In this, I am able to upload files till 100 MB using remote object (blazeDs) where we will read the file as byte array and send it to the java method. If the file size exceeds after that, then I get the run time error in IE.
View 1 RepliesI'd like to have Flex trigger the browser to download a PDF file from a server, but if anything goes wrong with the script that generates the file I want to be able to throw a meaningful error from Flex. Is it at all possible to try to open the URL in Flex first and check the response's HTTP status or Content-Type, then if it's a PDF file and not an error pass it up to the browser to display the "Save File..." dialog?
View 1 RepliesI have created a flex app that uses sockets. I published the flex app in a web application that runs on glassfish server. Now from that flex app i create a socket connection to a C# server and start sending/receiving data.The problem is that after i create the socket connection to C# server the flex app first checks the policy file, and after it get's it, it closes the socket, without keep the connection alive.[code] Now after i create the connection and it gets the policy from server it closes this socket, so to be able to use this connection i have to call again [code]After i do this, i can use normally the connection

I'm trying to write a test page which a customer can send us to identify whether they can use various parts of our site.

View 2 RepliesI'm looking to use the Smart Seek options with netStream in an upcoming project. Currently, we are using Flash CS4 and it seems this API is not available. Am I correct on this? Is this only available in CS5 as far as Flash Professional goes? What about Flex? Which version of Flex is required to access the smart seek API? Or am I misunderstanding this, and the Smart Seek API is server side only AS?
View 2 RepliesI have a problem loading remote XML file into SWF file.

View 7 RepliesThe following is my codes. This is still work in progress; so, you will see some functions with empty contents. Plus, this is my first Flex application; please bear with me. This is a quiz application that gets the questions and answers to each questions from a ColdFusion web service. There are three types of questions, True or False, Multiple Choice with single selection, and Multiple Choice with multiple selections. So, based upon the question type, the application would dynamically generate the appropriate amount of radio buttons or check boxes for the users to select. I got these working. The problem that I am having is, I am not sure how to check what the users have actually selected. In some other forums and posts on other web site, it said that I can use event.currentTarget.selectedValue to get the user selection. But when I actually do it, I got a run-time error saying, "Property selectedValue not found on mx.controls.FormItem and there is no default value." My question is, what do I need to do to capture the user selections?
[Code]...
This seem like a silly question but as far as I've found: It's impossible to reload an xml file from a remote location while the SWF is running.
For example, I have a kiosk project that will run 24/7 (with a restart each night). I have an "calendar events" loading off an XML file that I want to keep on a webserver so I can update the kiosk by editing the XML file. However, the SWF caches the first XML file and keeps reusing it. I'm testing this by triggering a function that reloads the XML file with a button click.
I found trick that concats a unique ID to the file name which prevents using the old file but that means I'll have an ever growing list of XML files in the Temporary Internet Files folder.
I would like to do a URLRequest to a PHP file which contains xml, and the PHP file will be living on a seperate server from my flash file. I understand there are security issues in this sort of thing. figure out how to make this work?

View 21 RepliesI have two variables that I would like to store in a remote data file which can be accessed by my Flash file. It is for a voting system, so the first variable would be a counter that is incremented each time a user votes, and the second would be the total rating. The average rating would then be calculated from these.
How would one store, retrieve, and then update these variables from the data file?
I can create the system within a single Flash file for a single session, but obviously I'd like multiple users opening the file simultaneously to be able to access the data and update it.
We have a Flash application provided by a vendor. It reads its parameters from an xml file on our web server's file system. However, it can also be spoofed to read its parameters from an xml file sitting on another domain's web server. At first we thought crossdomain.xml might be able to fix this, but we've researched it and understand the purpose of crossdomain.xml. It won't solve this issue.Are there any ways of enforcing that a Flash application reads its input file only from the same server where the Flash application was served? Or is the recommendation just to initialize variables within the Flash app, not relying on an external file.
View 3 RepliesI have an Adobe AIR/FLEX app packaged as a native installer application running on the desktop. From there, I need to do the following:
a) stay in the "app:" application sandbox so I can load "file://" JPGs into my mx:HTML control
b) authenticate with my server (CAKEPHP) to get a valid CAKEPHP Session Cookie, and
c) securely GET/POST XHR requests from javascript.
Can I authenticate using something like OAUTH or Facebook Connect without losing the application sandbox? It seems if I redirect from my mx:HTML, I lose my local privileges.Can I authenticate with my server using a different sandbox (remote?) and safely pass the Session Cookie to my application sandbox? Are either of these methods safe against scripting attacks?
