Flex or Flash im so confuzed?

Hi Guys
Im pretty new to Flash (migrating from Visual Basic), so I
apologise for my ignorance. My question is:- Do I require Flash CS3
or Flex (or both) to develope browerser based applications? I've
read loads of articles around the net, but still havent found an
answer yet.
Thanks in advance
Stefan

If you want to make a Flash-based application then yes, you
will need one of these tools. I believe there are a number of third
party tools that can also work to build flash-based projects as
well. But there are a multitude of different ways to build
browser-based applications. One of which is the language you are
moving from. Otherwise, you can use PHP, JavaScript, Ruby, Ruby on
Rails, etc

Flex SDK & Flash Pro

I don't program in Flex or Flash Builder. I tend to build my app interfaces as I go, So coding in flash professional seems the way to go. It seems to me that there are a lot of extra steps designing the interface, converting it to a flex component, and then doing all the coding in Flash Builder, when I could just do the coding in flash. This is from my stand point as I see it, having never programmed in Flash Builder or Flex. But there has been times when I thought. Wow it would be cool to use this or that flex component.
Anyway, getting to the question. I just noticed the other day that the Flex SDK path is included in Flash pro CC. Why is this? Does this allow us to use some of Flexes capabilities in flash?

I think the intention behind that is so that if you connect it to Flash Builder it will automatically fill that value in for you (FB needs it to be filled in, even if you're using Flash Pro as the compiler). However, like many features that are related to using the two tools together, it doesn't work properly.

When to use Flex Or Flash Or HTML-Javascript

I am Experimenting with Adobe AIR. I know AIR Applications
can be developed either using Html-Javascript Or Flex Or Flash.
But can anybody HELP me understand when do i exactly use Flex
or HTML-JS.
Well i know one of the reason to use Flex is to build
RIA's.What are the other Possible reasons ?? can i draw a Decision
Boundry between them??

The best reason to choose one tool over the other is that you
have something working in that language already, and are just
extending it into the AIR world.
If you're starting a new project, you then have to balance
tools you have and know how to use against the strengths of the
tools. A tool you don't know has to have some pretty compelling
strengths to make you take the time to learn it, unless you're just
doing it for fun. If not for fun, the effort has to pay off, yes?
Very generally speaking, here are the strengths of the tools,
as I see it.
For HTML + Javascript, just look at what you see on the web
today. People are pushing browsers pretty hard these days with web
apps, so that gives you a good first-order idea of the power of
this tool set. The AIR environment does give you some more power,
not just in the AIR APIs, but also in having a single modern
browser to develop for, so you don't have to limit yourself to IE6
compatible code. Still, it's not yet the equal of the other tools
in some areas.
Flash's main advantage over the others is in applications
with lots of graphics and animation. The reason for this is purely
because that's what the Flash authoring environment is geared to
produce. It's not got a very good ActionScript editor, and as a
consequence there's a practical limit on how much code you want to
write in a given project. It's not a question of whether you
can write a 20,000 line ActionScript program within the
Flash environment, it's a question of whether it's better done in
another tool.
One of the best "other tools" when you end up with lots of
code is Flex. With the "Builder", you get Ecipse, and without, you
are presumably using some other worthy programming environment.
But, you give up the graphic and animation tools from Flash, and
you give up a lot of the simplicity of HTML + Javascript.
You can combine them, of course. You could build a whizzy GUI
control in Flash to use in a Flex application which is hosted
inside a web page, for instance.

Flex or Flash for Live aud/vid webcam?

Hello,
I am new to Flex and Flash.
I want an application where clients should be able to do a
peer to peer web cam.
I would like to ask that Flex 3 is good to make P2P Live
audio/Video Webcam or should it will be easy in Flash.
Also will i need to use Any Server (FMS) or not as it will be
a peer to peer application.
What is required to be installed on Server.
Also on Client side only Flash Player is sufficient to Play
or there is something else also needed to be installed.
Please tell me if you know a good tutorial and help material.
Regards,
Saad

Hi,
If you must make application more flexible for you,
you must get Flex. it's an ide.
If you want to custom componant or animation you must take
flash.

"Unknown Flex Problem" - 'flash.filesystem:File' is undefined.

Hi,
I have written an AIR ActionScript Library project using SDK 4.0.
I had written code for most AIR components in the library, everything was working fine.
I then needed to add code for components like FileSystemComboBox, FileSystemDataGrid, FileSystemList, etc.
For this, I added airglobal.swc and airframework.swc to the library project.
I am getting the following errors:
'flash.desktop:Icon' is undefined.   Unknown    Flex Problem
'flash.events:FileListEvent' is undefined.    Unknown    Flex Problem
'flash.filesystem:File' is undefined.   Unknown    Flex Problem
Im guessing that the flash package is present in both playerglobal.swc and airglobal.swc and this is giving rise to the problem internally.
Can someone tell me how to overcome this?
Thanks,
Pradeep.

I am writing a library for AIR based projects. Any AIR flex project should be able to integrate my swc into their project.
The goal is automation.
So, I am having trouble automating FileSystem components in SDK 4.0 only.
The same is working fine in SDK 3.5 as it does not have a palyerglobal.swc included.
Can I remove the dependency on playerglobal.swc in SDK 4.0?

Scenario of such a Application where Flex and Flash combination is used

Hi ,
I am seeing this a lot in Job portals where the companys are asking for the combination of Flash and Flex .
Can anybody please let me know where exactly a combination of such would be required generally .(Means i need a scenario of such a Application where in Flex is used with Flash )
Please help , thanks in advance .

Hi Kiran,
          Basically flex is invented for developing rich internet applications and adobe introduced flash concepts in flex and flex will run on flashplayer.. so indirectly u are working on flash environment... any u are asking for the perticular scenario...
                       Take one example i.e u have an application that is displaying several photos slide by slide in ur website. ( with some animations and other effects that are not available in flex).. at that time u can go for flash developing.. u need to develop that in flash and import that into ur flex application
                  visit ur Tour the flex web and there in flex4 we have some realtime scenarios where adobe already developed a dashbord to display the world map and the density of adobe site users.. they are using ibm ilogix for dashbord..they developed this components in flash and they have used that component in flex ...we dont have some animations that are available in flash and also u can develop some components in flash and import them into ur flex application as swc format.and u can use them in ur application
                  i think u got my point... for this u want have glance please go through the link below
               http://www.adobe.com/devnet/flex/tourdeflex/web/
            there u have some dash board applications developed in flex and flash.. check it out ..

Migracion de flex a flash

good afternoon I wonder if I can migrate an application from flex to flash as it is done thanks for all your response I hope you have a good day

Programming in Flex is lot like a programming in Flash
professional. Fundamentally, Flex enables you to build and deploy
SWF files, the compiled bytecode that is interpreted by the virtual
machine known as Flash Player on desktop browsers.
The key differences between the two authoring tools are:
1) Flash has been designed to facilitate the creation of
interactive content, whereas Flex is geared toward application
development.
2) Flash stores your application structure in a binary FLA
file, whereas Flex uses a text file based on the markup language of
Flex, MXML.
3) Each tool also differs in the development model it
employs.
Hope that helped.

How do I import SWC files created with Flex info Flash CS4?

I've created very nice UI component using Flex 3 and I have exported it into a SWC file.
How can I import it into Flash CS4 to use it there?

Hmm... if you happen to be familiar with C#, then you may probably know about the problem of P/Invoke (this is a command that lets you access Windows API through C# code, which will apparently prevent it from functioning on other OSs).
What happens with Flex framework is somewhat similar to this. I.e. it relies to much on the features of Flex compiler and the components of the framework create a lot of cross-dependencies, which makes them barely usable outside the framework.
So, if you have time and doing this just as a matter of learning, I'd suggest you start an AS project in Flex builder and advance with it compiling it both with Flex and Flash to see if there are any differences (basically, once you see it doesn't compile / doesn't behave as you'd expect in Flash, you'll know you used something that is specific to Flex). These would be mostly meta tags, like [Bindable] for example.
And, if you need any tutorials on how to code in pure AS, then, well, there are really to many So that you can even choose what's appropriate / goes better with your learning habits.
If you like video lessons, there're tons of them at gotoandlearn.com, if you prefer reading documentation, here you go: http://livedocs.adobe.com/flash/9.0/ActionScriptLangRefV3/class-summary.html
if you prefer forums / written tuts, then, kirupa.com, actionscript.org, flashkit.com as well as Adobe forums will provide you with a lot of information.

Problem with NetConnection in Adobe AIR(Flex) using Flash Media Server.

Hi
I am creating a small chat application using Flash Media server. I have already created all my user interface components in Flex(Adobe AIR).In this application rather than sending text messages user can also send file to another user in his friend list.
problem what i am facing is, when i am sending file through FMS most of time it send successfully but for some files while sending application loss netconnection.
so i would like to know, rather than closing application what are other condition when FMS loses network connection?
Any help would be appreciated .
Thanks.

Hi. It looks like your code is not finding the mp3. At least,
I can reproduce your error code by removing the mp3 from the
directory, or renaming it.
Btw, if you test with FF instead of IE, you'd see the error:
Error #2044: Unhandled IOErrorEvent:. text=Error #2032:
Stream Error.
at KZFlash_fla::Sound_2/KZFlash_fla::frame1()
Hope that helps.

Problem with NetConnection in Flex using Flash Media Server

I'm attempting to place a function on a NetConnection instance, and from everything I've read, I should be able to do that. Unfortunately, I'm getting an error when I compile. Here's my code, and my error is below the code, please let me know if you have a solution. Thanks for the help!
import mx.rpc.events.ResultEvent
import flash.net.NetConnection;
import flash.net.navigateToURL;
import flash.events.NetStatusEvent;
import flash.events.StatusEvent;
import flash.text.TextField;
public var nc:NetConnection;
// init is called on creationComplete
public function init():void{
     nc = new NetConnection;
     nc.addEventListener(NetStatusEvent.NET_STATUS,onConnect);
     nc.connect("rtmp://localhost/FMSTesting");
public function onConnect(event:NetStatusEvent):void{
        myText.text = nc.connected + event.info.code;
//nc.myFunction is the function that will be called
//from the main.asc server side file and this is where I get
// the red x in Flex Builder 3 telling me there's an error
nc.myFunction = function():void{
error generated by the nc.myFunction line is:
1119:Access of possibly undefined property myFunction through a reference with static type flash.net:NetConnection
I tried putting the function declaration inside the onConnect handler and inside the init function, niether will remove the error.

Can you write piece of code which you can trigger on click of button. I mean put a button on your swf file say name it "btnstopPublish" and click on it. Write below code snippet in click handler of the button and see if it works for you,
btnstopPublish.addEventListener(MouseEvent.CLICK, stopPublish);
function stopPublish_Play(eventObj:MouseEvent){
ns.publish(false);
ns.close();
nsPlayer.play(false);
nsPlayer.close();

Flex 3 + Flash Player 9,0,16

I'm currently very close to deployment of a major flex 3
application deployment into a corporate environment with thousands
of distributed desktops. The IT group has Flash 9,0,16 installed on
the images for those machines, and a full rollout to a current
(9,0,115) version of the player will take months (don't ask,
they're mindbogglingly slow). Does anyone have a copy of the 9,0,16
Debug player for mac or PC? It's not in the fp_archive distribution
of historical versions. I've got some issues that crop up
specifically in this version of the player, but I can't find a copy
of the debug version anywhere.

Thank you for the help, however I don't see any publish
settings that would allow me to publish a swf for version 9,0,16,0
instead of the new version 9,0,124,0. If I go all the way back to
version 8 my AS3 and flv videos won't work anymore.

Flex, Air, Flash, Flash builder, ASC2.0

After the decision of moving Flex to apache, and with the release of Flash builder 4.7 I am getting a bit confused about what is what anymore.
Flex development is moving to apache, yet the compilers, packaging tools and more seem to live inside the Flex SDK.
Air SDK has previously gone on top of the Flex SDK and seems to be an addon on the Flex SDK.
However in flash builder 4.7, AIR SDK is set as the compiler even for web projects, although the result is a .swf file with no dependency on AIR.
On top of things now you can get AIR SDK with ASC2.0 that still can build web applications (non-air)
I am sorry if this is a stupid question, but Isn't this getting a bit complicated and terminologies getting mixed up?
Am I right to assume that things are moving towards the following:
AIR SDK - Compiler and core framework/Api for AS3 code that targets either web(swf), air or air mobile (this would be bundled with Flash builder), have command line tools, to build & package applications.
FLEX SDK - Frameworks for RIA apps (mxml files etc), but ultimately not necessery unless your doing those kinds of apps.

In the Flex/Flash world, everything eventually gets compiled to SWF despite how the source is written. SWF consists of media assets as well as bytecode that can be executed. This is very similar to the Windows world where EXE/DLL files may be a compiled product of C++, VB, Delphi, etc code.
ASC 2.0 is a new compiler that produces more optimal bytecode. While Flash is fast, the current ActionScript compiler does not produce good enough bytecodes that gets the best out of Flash player.
Adobe AIR provides additional capabilities outside of Flash Player to make the applications more desktop friendly. Flash Player is constrainted by browser security, therefore capabilities such as are local file read/write are limited. While the security makes sense, when it comes to desktop applications where security model is different, it makes sense to have extentions that enrich the user experience. Throughout the years, besides API additions, AIR grows to include capabilities such as packaging SWFs for mobile devices.
Flex is just a framework that's designed to make building business applications easier. However, business applications can be built without Flex framework.
p.s. I am not an Adobe employee, but I have been trying to clear this confusion for many people. It seems that Adobe's PR is not keen on communicating with developers, while they are awesome in terms of catering creative professionals.

Does Flex or Flash islands support ALV table scrolling ?

Hello experts,
if I have a webdynpro abap ALV table, no "real" scrolling in a large list is possible. The paginator buttons as well as the "scrollbars" always trigger a roundtrip, and it takes a moment or two until the next page or line is displayed.
A "real" scrolling would be like in Excel or in other web pages where you can quickly roll through a list, by using a scrollbar or the mouse scrolling wheel.
Does anyone know if this will be supported by Flash islands (in EhP1 maybe?) ?
Thank you
Johannes

I think you're mixing things a little bit. WebDynpro ALV table is one thing...and Flash Islands is another...you can't build an ALV inside Flex, at least no so easy.
ALV is an SAP Technology and it doesn't fit on Flex which is Adobe Technology. You can use Flash Islands to embed a Flex file into WebDynpro, but that in no way affect any WebDynpro standard components.
Greetings,
Blag.

Flex to Flash -- Flash to Flex
