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.

If this post answers your question or assistance, please mark it as such.

  • Flex 14 issue of Audio in Jack / headphones

    Hey, I have a flex 14 ideaPad and until recently all worked without problem audio-wise (when headphones have been and is not plugged in), except for randomly a couple of days, when I plugged the headphones in the plug and no sound came through the headphones or the speakers, although the headphones were detected by the laptop. When I unplugged the sounds would come again through the speakers.

    I tried again with a different set of headphones, but the problem came back that lead me to believe that the problem is with the laptop, after searching solutions online, I decided to remove it and then reinstall the Player audio (Realtech HD Audio Manager). This fixed the problem for a few days, but now the same problem is back. I'm confused as to whether this is a hardware/software problem based as when I reinstalled the driver he solves the problem, so he could not really related material being.

    If anyone knows what is the problem? Should I just continue to remove and reinstall the driver? Once again the helmet are detected by the laptop, they do not appear as their own reading device (is it always the case?)

    Thanks, Tiernan

    The configuration of Realtek on the Flex has Windows only show a single, common system for all the audio outputs.

    Here is the latest driver from Realtek. If the problem persists after, I would recommend a warranty call.

  • Flex Application issue?

    I created an application in Flex built with many components etc... My application is basically a questionnaire with many pages and after answers are graphically by a bubble chart.

    I fit my request in a 3rd party software which is a presentation player (who accepts. SWF files and uses the ExternalInterface class). I like my Flex to work on the player application is first of all when the player is running, my application will run by asking specific questions. Once the user has answered questions that they will have a "confirm" on the last Page that will take them to the table of bubble to another part of the player presentation for registration of results.

    My question is that my request has two pages of questionnaire and the bubble chart all encapsulated in a single application, is there a way for me to split my application in order to use questions and Bubble graphic separately as required by my presentation player?

    Currently, my application converts the results of questions answered in 3 main values, which are passed in the DataProvider for the bubble chart. Is there a way so that if I split my application into 2 separate applications, the 1st being questions and the 2nd by displaying the bubble chart, that I could spend the 3 values of the 1st application 2nd application so the graphic bubble could be shown?

    Thank you.

    Hello

    using modules may be an option. You can make a separate bubble chart

    module and questionarries separate module. Thne as your questionarries

    the article will come first you load Fürst and then load bubble

    graph in turn.

  • Keyboard structuring issues trigger

    Is there a limit to how many triggers you can use?

    I have 10 sets of hands for each arm. I want 6 positions each side arms. You can the subsets of the hands for each position of arms?  Example: left arm carried outward by side, have 4 hands thumbs up, thumbs down and so on... I have A trigger to thearm, then u = thumb triggers to the top and e = face-down. I have 6 positions of arms with hands of 4 to 8 per arm. Is this. Possible? How should I do?

    Triggers can be uppercase and lowercase?

    Thanks for the help

    BY

    Currently, triggers are alphanumeric - A - Z and 0-9. Case is not serious.

    Yes, I understand what you try to do it properly, you can reuse the triggers. So, for example, that let's you have arms 1, 2 and 3 at the same level with brothers and sisters of masking in, and only appears at a time. Then inside each keep you U for inches to the top and D for the thumbs down, no matter what arms fires.

    So for 6 arms (3 on each side) each with 6 hands, you could set up as:

    • Left arm

      • Left arm 1

        • Hands A, B, C, D, E, F
      • Left arm 2
        • Hands A, B, C, D, E, F
      • Left arm 3
        • Hands A, B, C, D, E, F
    • Right arm
      • Right arm 4

        • Hands, G, H, I, J, K, L
      • Right arm 5
        • Hands, G, H, I, J, K, L
      • Right arm 6
        • Hands, G, H, I, J, K, L
  • Flex 3 issue of Libs folder

    Hello

    I have a few swc files in my folder libs I use not. The unused EFA will be compiled in the Release version?

    For example, if I have a CFC with a button skin in my libs folder, but I don't use this button skin, is it compiled? Will save any space in the Release version of the slaughter of my libs folder?

    Thank you.

    -Laxmidi

    Only classes found through searches of dependency will be used.  If the skin is

    referenced from a .css file it might get used otherwise no.  But all the SWCs

    get read by the compiler, so it can slow down the compilation a little.

  • Dir structure has changed, now get Destination "DefaultHTTP" has no channel...


    In order to get my application Flex works with versions of Maven, I

  • Previews of document - using OLE server? or other means

    Hey all,.

    Asked me if Flex can be used to communicate with an OLE server? I guess the idea is that flex can issue a command to the server to generate thumbnail previews and get it. I tried to get him, but found almost nothing. Anyone here knows?

    OR

    You know a way I can generate previews of document in Flex (documents like MS Word, Excel, Powerpoint, etc)?

    Thank you

    You could make OLE Automation through external calls to JavaScript script blocks and drive the word somehow you want as long as the word is installed locally. Is that what you want?

  • How could get the categories of items and Module-specific to the company?

    Could we make it point to organization and specific Module categories? At present, the same structure of flex 'Categories of elements' is used by management of orders (already implemented) and now the purchase of / iProcurement (executed). To make category and module-specific to the company, we need to attach a value based on a custom SQL?

    In the implementation of the OM, we used flex structure "Article catégories" for items of products finished. Thus, a finished good CEMBAG has CEMENT category. BAG attached to it. Cement bulk's CEMENT. In BULK which are related to it. In this phase, we create spare parts using the same category structure (I was wondering, if we should change it). But now, when we will implement an element, we see all categories, for finished products and spare parts in all of all businesses. So, we see Working CAPITAL. BALL.., ELECTRIC. AMMETER... OM alongwith categories. We cannot change the default category value for the management of orders or inventory (already implemented), but it looks like that we would have to change the default category for purchases of separate categories. Also need to separate the research as the reason Codes. Tell code for a reception various gives all reason codes, those created for the management of orders and purchases.

    You must make sure that the categories assigned to the entire old category also appear in the new category.

  • Complex issue of Flex application design

    I'm new to Flex and just started working on a retail online store application.
    However, I came across a problem and I'm stuck.

    Here is the structure of my application:
    I have an application file - Main.mxml and
    two modules - LoginModule.mxml & MainModule.mxml files
    and I load the module LoginModule.mxml by default and after a successful login, load MainModule.mxml


    The MainModule.mxml has a sample of flexstore similar viewstack
    and contains the elements of the view - Home.mxml
    Products.MXML
    ... etc.
    The Products.mxml's filter section, product catalog, shopping cart Panel
    (similar to ProductsView.mxml in the flexstore sample).

    Here's the question:
    Whenever I click on a control (checkbox, combobox.. etc) in the filter Panel
    I get an error message, as shown below:

    The box can be found here:
    TypeError: Error #1009: cannot access a property or method of a null object reference.
    at mx.managers::PopUpManager$/addPopUp()
    at mx.controls::Alert$/show()

    at mx.core::UIComponent/dispatchEvent()
    at mbzprodsView::GroceryFilterPanel/::dispatchFilter()
    at mbzprodsView::GroceryFilterPanel/__cbBreadRoti_click()


    For Combobox, click:
    TypeError: Error #1009: cannot access a property or method of a null object reference.
    at mx.managers::PopUpManager$/addPopUp()
    at mx.controls::ComboBox/::getDropdown()

    to mx.controls::Button / http://www.adobe.com/2006/flex/mx/internal::buttonPressed()
    at mx.controls::Button/mx.controls:Button::mouseDownHandler()

    However, the MainModule.mxml file works OK if I convert this component in a file of the Application of the Module.

    Not sure if it is a limitation of Flex 2 or I need to organize files in a different way.

    Any help will be greatly appreciated.

    Thank you very much

    Found the solution in Michael Ritchie's Blog. Thank you Michael. I lost two weeks of my time on this issue.

    Included the code below in the script of my application file block and it solved the problem:

    Oh, the aproval was fast it is news.

    So, the solution:

    
    
    
         
            [ResourceBundle("resources")]
        
    
         
              
         
    
         
            
            
                
                
                
                
                
                
            
            
                
                
                
            
            
                
                
            
            
            
                
                
                
                
            
        
    
         
         
    
    

    Just take the XML structure on the element. Having it declared inside the component is not really good in this kind of situation because the structure may not be initialized properly (the Resource Manager cannot be instantiated properly or structure may not correct access - there are some questions that might come into play).

  • Issue in Flex application with J2EE capabilities

    Characteristics of the environment:
    Eclipse: 3.2.2
    MyEclipse: 5.5.1
    Flex plugin version: 3.0 (Beta 3.0) + LCD 2.5.1
    JBoss 4.0.1

    I followed steps are:
    1 created flex project (in which I used mx:OLAPDatagrid)
    2. features of web-project added to it.
    3 deploy in Jboss

    After deployment, his error showing as: "could not resolve < mx:OLAPDatagrid > the components."

    Can someone help me please in this issue.

    Thanks in advance

    Hello

    The OLAPDatagrid component is available only in the version of Flex Builder Professional. For the first problem, the one where you build a Flex + LCDS 2.5.1 project, the answer is that LCDs 2.5.1 do not include component OLAPDatagrid and that means you have found errors on the duration.

    For the second problem, the one where you try to use the compiler for J2EE module, the answer is that the compiler J2EE module supports only the components that come by default with flex sdk.

    Thank you

  • Issues of security in the connection between the customer and provider of flex property

    Hello

    I should probably know this, but the customer is concerned about a security problem.  I do not think that

    that is a problem, but its best to ask and be sure.

    In my flex client, I got a dialog box where a user can enter a password.  I then take the password

    and send it to my supplier of the property.  This normal text password, I don't do anything to encode it before sending

    It's on.  Is this ok? I think that the connection is secure, but please confirm this, or should I encode them before you send it?

    Thanks for the info

    Yes, the data Manager API using secure AMF channel.  Even if your plugin called java service, you must use "/.../messagebroker/amfsecure" for the channel of proxy URI as shown in the SDK examples.
