Flex :: Advantages/Disadvantages Of AIR Vs Flex/Web?
Jun 15, 2010
I'm tasked with writing an application for placing and connecting objects (sort of like a room planner where you can place furniture). i've made a demo using Flash Builder 4 and built it for AIR as a desktop app. Now the client wants the full app, but they and I am unsure whether to continue building it as an AIR app or transform it to a web application using Flex. I tried making a simple conversion of the AIR app to a web app, and most things worked but not all. The things that don't work seem to be simple bugs, though, not complete lack of capability.The capabilities that I'm going to need (except for the modelling) are: Printing of the finished image + a list of the furniture that has been placed
A way to save and retrieve finished plans
A way to export the list of furniture to Excel format
Handling a whole slew of data about the different objects
Only the printing has been implemented so far, and seems to work in the web app as well.What advantages/disadvantages are there with the two approaches? Are any of the capabilities I need much worse (or even impossible) to implement in either approach?
Disadvantages
Requires Flash 10 (for saving files)
Requires a web server to serve content
Sligthly longer development time (from where I am right now)
Requires an internet connection to work
Lots of data transport, may be slow on a slow network
Desktop AIR app
Advantages
Slightly faster development time (from where I am right now)
No web server necessary
Can be used while not connected to the internet
All data is local and faster to load
Disadvantages
Requires the Adobe AIR runtime + a separate installation of the program
Updates need to be distributed to all users and an admin needs to install them
What are the advantages and disadvantages of having just one main loop and having a main class control individual objects on your stage, in oppose to having each individual object have its own loop and giving it the responsibilities of doing what ever it has to do on its own. What are consider best practices.
As it is said here: [URL] "If you do a Google search today for "MVVM and Flex", the first post is by somebody who claims that MVVM is not a good fit for Flex. I couldn't disagree more. Out of the box, the Flex framework makes it much easier to implement a Presentation Model than similar MVVM implementations in Silverlight. That is not to say that there aren't good third-party libraries that make it easier in Silverlight, but without any help, it is easier to do in Flex." So MVVM as LOGICAL CONCEPT can be implemented in both but the way it is implemented in Silverlight requires more Plumbing than Flex.
What prevents Silverlight MVVM to be implemented like Flex ? Doesn't Silverlight have same capability in event system to do the same? If yes why does Silverlight do things more complicated what's the advantages then ? Is it about using Class Interfaces which are more strongly typed? What are the disadvantages also ? For example as for implementing MULTIPLE VIEWS for 1 View-Model does Flex implementation make it also more obvious?
I was reading these days about large projects implementation in python and Flex, and very often people praise the use of framework (like Cairngorm, PureMVC or others) over traditional OOP coding.
I think i dont really understand the advantage of using FW, which is the strong point over classic programming? how big should be the project in order to use FW? it is intended mainly for web-applications? or can be used for desktop apps as well?
they both seem to accomplish the same things with different syntax, whats the point of using two different technologies. highlight every possible benefit of using mxml. Also are there scenarios when one is more beneficial than the other and why. clarify this runtime behavior of mxml vs AS3 as discussed in Oreilly Flex 4 Cookbook page 1:
I've recently started making a game in FlexBuilder. The game is currently a Flex project. Is there any downside to using Flex as opposed to just Actionscript? A friend of a friend told me that Flex is slower than an Actionscript project. I've been unable to validate this on the internet; is there any truth to that claim?
I wonder what are the advantages of using document class?Is it just to make the execution of code faster or else? If you know the advantages of using document class please reply.
I want to release my flash application not in release mode but in debug mode to see result of trace() after releasing the app.
I don't care that debug mode makes processing speed little slow.Except for processing speed, are there disadvantages to release flash application which was compiled in debug mode?Is it possible that the app throws exception or Flash Players of the app's users crash due to debug mode?
I am a professional video editor specializing in corporate video and occassionally TV commercials. We often post "review" videos in Flash format to our website for our clients to check progress, etc. These videos are usually around 3 minutes in length and occasionally reach 20 minutes Trt. We use Adobe Production Premium CS4 which includes Flash CS4. I usually export the videos at the included preset, "Web Large Widescreen". The playback is almost instantaneous on most DSL and T1 connections. I use the "Full Screen" option button and when the videos are viewed full screen, they look amazing.
Here is the issue: I have recently created a video for a client that contains text and is approx. 50 minutes in length. The video format is 4x3 and the client wants the transcoded Flash video to display at a 640x480 square pixel dimension. The video plays fine over most DSL connections. It chokes on T1. Question: Can streaming Flash video provide better quality and playability for longer duration Web videos? Could any of you direct me to a chart that compares streaming Flash with the "simulated" streaming typically exported from Premiere CS4's Media Encoder?
where I can find info about compiling flex 4.0 sdk on flex 4.5/4.5.1 sdk.I am having troubles. compilation goes well on 4.0 but whe I compile on 4.5 or 4.5.1 I get blank swf.
Note: I have set flash player 10.2 for compilation and also as default.
class Foo { [Bindable] public var property: String; }
The class Foo has an implicit event dispatcher to handle property change events. How can I access that without making Foo explicitly extend EventDispatcher?
I wish to develop a softare for 3D object compression (by polygon reduction) in flex using papervision 3D. Could you please suggest me an efficient algorithm for the same?
I have implemented application client-server with spring blazeDs message services using JMS message destination. The idea is a producer declared in Java send message using activeMQ and consumer declared in Flex receives them. I have configured the AMFChannel with a polling interval 0, but I have seen when the consumer subscribes to the destination in Flex, the time request can be of up to 3 seconds.
I have a tree with nodes , and a delete button , first user select the node and click this delete button , I want this node to be removed from the tree , Its not XML , every node in tree is of type Object
{label:'folder',children:[{label:'file1'}]}
I tried delete myTree.selectedItem (but compiler wont let me do it) also tried myTree.selectedItem = null (just unselects the item)and also how can I access reference to parent object of myTree.selectedItem ?
im trying to output my database information in a text input field in flex by using remoteObject(cfc). The information is being provided by a database using a query and an array collection. I'm just unsure how i go about taking the queried array collection information and display it into TextInput Fields.
I am trying to access html files protected by basic authentication. Below is the code to do that but I still get the authentication dialog. I checked the fiddler and found that for the first request authorization header is present but for the subsequent requests which is requested to load the .js, css & images the authorization header is not added. This is the reason I am getting the auth dialog. Is there a way to add authorization header to the subsequent requests as well?
I have a TabNavigator, and each tab is a Module. One of the modules is labelled Units and the full code of the module is posted in this post. There are several problems:
1) Forms are not populated with data from the datagrid selection. 2) Selecting a row and clicking delete gives the very-common error: TypeError: Error #1009: Cannot access a property or method of a null object reference.
A trace on the valueObject unit within the selectionChangeHandler function gives NULL. Why? Note: In other modules (other tabs of the TabNavigator), I have DropDownLists populated with units. This means that the valueObject Unit is defined in the other modules. However, valueObjects should be private to modules, and not shared.
ow do you display HTML formatted text in a Spark custom item renderer (Actionscript)?
Sample Code:
The html content in item.post_content displays as plain text in the IconItemRenderer messageFunction snippet below (which is just the default generated code for Icon Item renderer):
I am working on a grid example in flex using advanced grid control. I know we can easily group data by specifying the field name. At the group node level, other than the gorup name I want to be able to show data in the rest of the cells ( calculated data ) and I am looking for some dataRowBound event or similar to be able to hook some data in it.
Example: Grid displaying list of towns grouped by state. At the group level ( for each state) I want to show the total number of towns in each state. Here how can i show the total number in the town column.
I've embedded a MovieClip symbol with the [Embed] syntax into my AS3 project, which I'm compiling with the Flex 3 SDK. That MovieClip has instances of other clips within it that are placed on stage with instance names. I can't just access them by instance name like I would if I were compiling with the Flash IDE. How can I reference them?
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.
