• Flex application and several basic material

  Hello

  my company is developing an enterprise application pretty huge involving 4 Flex, BlazeDS, a server side Java-spring and frame matte on the client side.

  It works very well but as demand is growing bigger and bigger performance problems are a major concern for us... And our customers!

  We just noticed a performance problem and I could not find any resource from Google, it's here:

  It seems to us that no matter what the number of CPUS of your computer has, our Flex application always use only one. Accordingly, our application rolls over on a P4 core at 3 GHz computr processor than, say, on a core i7 with 8-processor 1, 6 GHz! Pretty strange isn't it?

  However, I learned that multicore of handfuls of Flash Player since version 9, so perhaps am I missing something simple? Is there something I should do to enable multicore processing? What is my application which is poorly designed? Or an operating system issue maybe?

  Any help would be greatly appreciated

  Thank you

  ActionScript is single-threaded, so there is no advantage to try to spread his treatment between multiple cores.  Once the actionscript code has implemented the displaylist for a framework, certain aspects of the rendering of the display list can be distributed to the other cores or even a gpu.  Use the performance profiler to see where you as usage patterns are expensive and optimize.

• Flex structural issues

  Hello

  I am in the planning stage of a new project and am not an expert in flex (I plan a consultant), but I try to understand if Flex is the right tool for the job.

  Basically, the system consists of 5 modules, each with 10 to 20 questions. Each question consists of a streaming video and then a multiple choice question. The system must track the results of each question and then write the result in the database at the end of the module. Is Flex the right tool for this? Second, I want to be able to add/edit new issues and/or videos easily - what is the best way to structure this (you don't need to be too specific, I just plan it)? I guess that I would have some sort of XML file external that contains questions and a reference to the relevant .swf or .flv video file and another file maps the questions about the modules - makes it his right? I guess that the SWF, flv and xml files would all work with a php script allowing to save results to the database for logged in users? Any help or advice on the structure of this would be much appreciated :-)

  I also understand, Flex can exit projects for either web or use offline (via AIR (I think), but if we create a full application based on the web with flex, including an interface with a Mysql database, can we then export an offline version too, without creating new things? Sorry if this is a stupid question, I'm a beginner an intention to hire an expert Flex if we decide to go with it.

  Thanks for your help,

  Dave

  Flex is an excellent choice for this system.

  Regarding the best way to structure the application, you alluded with modules, and this would be the way to go. You could an XML file so that it contains the questions, or you can store the data of the question in the database as well.

  You can simply use PHP as middleware between the user interface and the database, or you might consider Zend, WebOrb, and Coldfusion.

  You can create a Flex application for the web and an AIR application for offline use, but there will probably be differences even between apps, so no, you won't be able to write an application and use it online/offline.

  Both applications share a lot of code, but AIR apps allow you greater freedom take advantage of the office, so use it to your advantage, but the application of sharing codes, with classes and the custom components in the architect.

• New Flash Player 9.0 puree to the top of my Flex application

  Hi all
  
  Today, I noticed that a new flash player 9 be downloaded ican, so I installed and I wanted to continue with AS3 coding with my Flexbuilder 2.01 (with fix 2).
  
  After the first start of my Flex application, I deeply regret that I have installed the cause of the "latest" flash player doesn´t flash player behave that the old player for Web service calls (or maybe my implementation of Web service calls). My will bring App Flex can´t connect more to the Web service. I have to give a look at what has gone wrong, but I'm really AMUSED that the player has no backward compatibility. This is not a new version of Flash player, its still a version 9.
  
  I guess the new flashplayer is from the SDK in Flexbuilder 2.01 Hotfix 3 and the current BETA version of Flexbuilder 3.
  
  Has anyone else you have same problems with webservice communication after update?
  
  Best regards
  Kcell

  Hi all

  today I found the reason of the accident, that occure when my application calls him Web service works in the new Flash Player 9.0.115).

  The reason is that in the function ResultHandler the webservice call it were nested terms "switch" used and missed in two branches "case" a "pause." So the problem could be fixed easily, but I just want to inform people if you have a similar problem, they should try to start the issue with Manager of result/fault 'empty '.
  (the old version (9.0.47) seems to be more robust against a 'pause' missing; but for sure to have other leaks)

  kepp both on bending ;)

• Refresh the browser of the Flex application?

  What is the syntax to issue a command to refresh the current browser window?
  
  I think it's a quick and easy way for the user to 'start from scratch' in my Flex application.

  Here you go, more easily:

• Style in mobile application issues statement (does not work)

  Hello

  In a simple mobile Flex application, I have a simple view with a styleName assigned to a VGroup it contains. The decleration is in the same point of view (for the sake of trying to make this work, but it is in an external css, if I find a way to make it work).

  The padding, I assign just does NOT at all. Nothing. While if I specify in the VGroup directly is paddingTop or another style, it works very well

  Weird behavior.

  Here's the view:

  <? XML version = "1.0" encoding = "utf-8"? >

  " < = xmlns:fx s:View ' http://ns.Adobe.com/MXML/2009 "

  xmlns:s = "library://ns.adobe.com/flex/spark" title = "HomeView" >

  < fx:Declarations >

  <! - Place non-visual elements (e.g., services, items of value) here - >

  < / fx:Declarations >

  < fx:Style >

  {.myGroup}

  paddingTop:200;

  paddingLeft:300;

  paddingRight:30;

  }

  < / fx:Style >

  < s:VGroup styleName = "MyGroup" >

  < s:Label text = "Hello" / >

  < / s:VGroup >

  < / s:View >

  Anyone has any idea why?

  I use Flex 4.6/AIR 3.6 for the moment, he tried with Flex 3.4 4.9.1/AIR too, same behavior.

  Is this a bug? I'm doing something wrong? Y at - it a hack/trick to make this work that specify the styles directly in the MXML?

  Thank you.

  Just realized that the padding in the VGroup aren't styles more but is properties. Damn these spark components

  I guess that's why, and I think it's a disappointment. I know that I could hack this, but condemned me!

• What is the technology used for the integration of java with Flex application?

  How we integrate java into a Flex application or how to build flex applications that use Java as a backend?

  BlazeDs is currently used in businesses to serve the above purpose?

  Or is there a better technology that is used in businesses for the integration of Java with Flex application?

  What is the latest version of BlazeDs?

  Also, please give me a few important article links which shows a sample application in Flex using Java development as a backend.

  Thank you in advance.

  BlazeDS is the way to go. Just google BlazeDS and you will find many examples of link Java to Flex via Remoting and BlazeDS.

• Dynamically change the title of the browser in the Flex application

  In order to make my Flex application more accessible to those who use screen reader software, I need to change the text of the title bar of the browser that the user selects different tabs. I thought I could use FlexGlobals.topLevelApplication.pageTitle = "xxx" to it or define a public function in the MXML application file and use topLevelApplication to call it.  However, this does not seem to work, the title bar is not changed. I wonder if this requires flex 4.6 (I currently use 4.5).  Any ideas on how I could do this would be appreciated.

  Hello

  BrowserManager allows to change title and browser header text.

• Is it possible for a flex application to reproduce a structure of files and folders to the customer without zip

  I have an upload/download of flex based app that works very well for download, but when it comes to download, I have coldfusion zip files and folders together and then just by downloading this single file.  I would like to have the flex application to replicate files and folders on the clients computer without having to zip & unzip them and I was wondering if this is even possible.  If I remember correctly, I thought that flash could not create folders on the clients computer...

  Thank you!

• Save the Flex application as a service

  Hello

  Is it possible to save Flex applications as services? And by here I mean--taking the example of Android - the app is closed, but still running in the background (not visible in the Task Manager).

  The reason why I ask, is that if for example I want to have notifications in real time, of events at certain times or things of the location function, I need the application to be "aware" all the time but taking place as few resources as possible.

  Also, it would have been nice setting to start at system startup and so on.

  Thank you.

  Well, he gives examples of what you can do with this thing, but you can do much more... On a native android app, you start a service at the launch of the system in the background to check what you want to check.

  In this example, we start a service when we start to demand... You can change to start the service at the launch of the system and start the main activity (to launch your swf) from the service!

• FileReference - crossdomain.xml - restrict access to all MY Flex application?

  I have a Flex application based on the web (domain A) concerning must download files on the desktop of the user FROM an external server (domain B). I use Adobe FileReference class to do this. Now, I know that I need a file crossdomain.xml to the external server in domain B to establish trust between the Flex application and the server download. In the end, I need any user to any domain to have access on the server download for the cross-domain file must specify:

  allow-access-from domain="*"
  
  But this will open up acess to the downloadble files to any flex app out there on the web . Is there a way to restrict access to just MY Flex app in the
  crossdomain.xml file?
  
  thx in advance!
  
  -MC

  Why do you need any user to any domain access?

  Anyone using your web application will be in area a. unless you count should the swf for others to download from their servers (which woiuld be strange)

• Simple Newbie Question - download flex applications

  I'm very new guy, sorry for the stupid question. It is my first adventure in Flex.

  I'm working on a graphic spring flex application and I went to show a worker co on his computer and it wouldn't work. I went to the html file in the bin-debug, it works on my machine, but not hers.

  This also got me questioning what I have to download online when I'm done so that it can work.

  The paths of the library are all absolute links on my machine like that

  C:\Program Files (x 86) \Adobe\Adobe Flash Builder 4\sdks\4.1.0

  Any help is really apprieciated. I did a few tutorials, but none of them actually go to upload files.

  Thank you

  Hello

  Your Flex program will work on your computer if you are using Flash Builder because it puts in place a 'special' environment to allow you to test your applications at the local level.  These files are all based on mxml and do not work outside the Flash Builder environment.

  For others to access your application, open the Project menu, and then select 'Export Release Build'.  This will create the code html, swf and other files for people using your app.  The main application will be the same name as your project - something like: myApp.html.  (unless you have changed the default application)

• In Flex application feature sometimes works and sometimes does not...

  Hello

  Please help me on this...

  In my flex application features works sometimes and doesn't work sometimes does not...

  In my project, I have 5 sections with 5 separate screens... Each screen is a module of different.

  After logining in the application:

  I'll go to a screen... First time each feature works in this form...

  Ex: I have a screen with datagrid. This user select name from a datagrid job click on the next button...

  According to the name of the selected user work, I display information on the next screen and customer names.customer whose name is a drop-down list box.

  Here is the code:

  public void populateAllOEMCustomers(event:ResultEvent):void
  {

  1) var object_CustomerList:CustomerList = event.result as CustomerList; the values of the object //Assigining the object reference variable result.
  
  (2) var allOEMCustomersCollection:ArrayCollection = new ArrayCollection(); Variable declaration ArrayColliction referance.
  
  (3) var i: int = 0;
  (4) var customerComboLabel:Label = new Sun;
  
  (5) for (i = 0; i < object_CustomerList.arryCollCustName.length; i ++)
  {
  var strCustName:String = object_CustomerList.arryCollCustName.getItemAt (i) m:System.NET.SocketAddress.ToString ();
  var strCustId:String = object_CustomerList.arryCollCustId.getItemAt (i) m:System.NET.SocketAddress.ToString ();
  
  customerComboLabel = new Sun; Dynamic Declaration of the label.
  
  customerComboLabel.name = strCustName; Assinging the customer name in the label name box.
  customerComboLabel.text = strCustId; Assingning the customer id in the text box on the Label.
  
  allOEMCustomersCollection.addItem (customerComboLabel); Addition of Lable in the referace ArrayCollection variable collection.
  }
  customerComboID.selectedItem = ' - ';.
  OEMCustomersComboID.dataProvider = allOEMCustomersCollection;
  OEMCustomersComboID.selectedItem = - 1;

  }

  This feature works very well when I visit the first time on the screen... If you go back to another screen and return to the same screen and click the button following this names combo box customer time has no customer Details... I get Nullpointer Exception and it shows the number of the line 5 (I gave the above code number..)

  If I change the first line of the code to the following: each time the feature above works fine. Not getting no not an error msg...
  

  var object_CustomerList:Object = event.result;

  If I type cast in specific class (CustomerList), the feature does not work... do null pointer exception... If I type cast to object everything works fine... In my code each time I'm typecasted for the features of the specific class is not working (gettingNullpointerExcepion).

  Please help me on this... I don't get what could be the reason...

  I am using::Flex 3, Flash player 10.1

  Thanks in advance...

  Kind regards

  Hi Satya,

  This sometimes as in your case may not work the way you have specified the RemoteClass attribute in your AS class. Because sometimes there may be a case because before it is mapped to a server-side, you are returned to the data and so that you can not get your custom class data but as normal object type.

  So to avoid this, you can map the class server-side for as classes in the Manager PreInitialize itself as shown below:

  Specify the preinitializeHandler in your main application and write the function below. That way, too, you can map as classes on the side server. So you will have no problem referring to your application AS class types.

  You can use the same line for recording of all classes. Using this, you can remove all of the [RemoteClass] attributes on all CLASSES and attach it to the unique place.

  preinitialize = "onPreinitialize ()" "

  private function onPreinitialize (): void
  {
  registerClassAlias ("com.expeditor.ScriptAdmin.Objects.CustomerList", list of clients);
  }

  In the line above the quoted string code refer to the namespace of the class on the server side and the second is your AS class. Also, remember to import the namespace from the correspondent as a class in the file.

  Try this and let me know...

  Thank you

  Jean Claude
