Learning Flex step 1

Hello,
My first post here. I'll just confess here and now that I'm
not very familiar with code. The little that I'm familiar with is
from Flash and Dreamweaver. I've never hand coded. I rely on the
software to generate it.
For what it's worth, I have worked on the design side for
years.
I have two questions.
Is is possible to learn the basics of Flex using only design
mode.
What/Where would be the best place to learn Flex given my
limited programming experience.
Thanks in advance,

Thanks mouse
I subscribed to Lynda.com premium subscription this morning.
Worked through
the first two (of three) video tuts for Flex by David
Gassner. This has
already been worth the money. So many more tuts to go and so
little time.
I went shopping on amazon as well. Those should all be here
tomorrow or
Friday.
I already know Flex is the future :-)
Thanks again
Bill

Before learning FLEX what i should do ?

I have started learning Flex programming blindly. Can anybody suggest me what things one should know before learning Flex. Detailed guidance is needed.

It really depends on your goals and background.
But in general, if for now you simply want to get at general Flex programming, don't buy a book, simply go the Flex 3 help system (here presented as a LiveDocs link for your convenience):
http://livedocs.adobe.com/flex/3/html/help.html
Even if you only go through these pages for a week and then go off on your own and start just building apps, you will have gained great insight into the major constructs present and necessary in Flex applications.
If you learn better through videos, then ToTal Training or lynda.com are good, though they don't compare to the above Flex 3 help system at all:
http://www.totaltraining.com/prod/adobe/flex3_riaa.asp
http://www.lynda.com/home/ViewCourses.aspx?lpk0=205
And if you want tutoring/training:

Help with article from learning Flex

Hi,
I was trying the examples on the Learning Flex site:
http://www.adobe.com/devnet/flex/articles/datamodel_print.html
I did manage to fix all the compile issues (Flex 1.5 to 2.0)
but I stll cannot get it to work.
For starters it doesn't load the info from the xml files.
Second if I use the following :
<mx:DataGrid id="empGrid" dragEnabled="true"
dataProvider="{empModel.employee}"> it gives an error when
trying to add a new employee
if I use:
<mx:DataGrid id="empGrid" dragEnabled="true"
dataProvider="{empModel}"> it adds it properly (minus the
Location which doesn't get loaded). Also when used this way it adds
scroll bars around the panel.
Can somebody explains why it doesn't load and what is the
difference between:
dataProvider="{empModel.employee}" and
dataProvider="{empModel}"
I have attached the modified files:

If I move the xml to an external file and use <mx:Model

Help required in starting to learn Flex 3

Hi All,
I want to start learning Adobe Flex 3.
I have various questions.
1) What is the difference between adobe flex builder 3 and adobe sdk 3.0
I have heard that flex builder 3 is commercial and adobe sdk is freely downloadable. I would like to know the steps from starting to start learning and writing a simple program using adobe sdk 3.0. I am a layman in flex 3. Please help me.
2) which book or site can I refer to start learning adobe flex quickly.
Please guide me as I am unable to start learning on my own currently.
I am using Eclipse 3.4.1.
Thanks.

Hi,
I think you have to go through sample application made in the Flex, so you will get idea what can achieve with Flex. Here is list of some link hope this will helpful to you.

Help me figure out where to start learning flex/flash/air/etc.

Hi all,
I'm hoping a few generous souls can help figure out where to start learning to use Adobe programming / application tools. I've read through a lot of the info on Flash, Flash Builder, Flash Catalyst, Flex, Flex Builder, Actionscript and Air – and frankly my head is spinning.
Let me give you some context of what I know, and where I'm trying to get to.
What I know
CS4 - Dreamweaver / Photoshop / Illustrator / Fireworks
Raw html, and some css
Various macro languages over the years (excel - macro level meta-procedural stuff)
Basic database experience (mysql, database design)
Training in procedural languages like Pascal about 100 years ago (ok maybe 20)
Where I want to go
Develop online trivia application
Multiple, simultaneous users
Polished interface (look and feel wise) - 'flashy' if you will
Database connections on back end to serve questions and manage users
At a very basic level it would be similar to those trivia systems you see in bars, like this: http://www.buzztime.com/games.html , but with an educational focus / spin to it.
When I want to get there
I realize this isn't going to happen overnight. I'm hoping if I spend 20 hours a week or so I can put something basic together by the end of the summer. This is as much about learning the tools for me as building the app.
How I need help
I plan to get a Lynda.com subscription to help me learn the tools. The basic problem is I don't know which tools to learn, in what progression, to accomplish my goals. If I'm never going to use Actionscript or Air I'd rather not learn them. So what I need is 2 pieces of advice
For the app I described, what tool(s) would you build it in?
What is a good learning path for those tools?
Thank you in advance for any advice you can offer, I really appreciate your help!
Larry

For creating a web application using Flash, there are broadly two workflows (with different tools to use):
If you are a designer, you may want to start learning Adobe Flash Professional for a more design oriented feel application development:
http://www.adobe.com/products/flash/
You can start learning how to use the tool from here. You would also want to keep checking our developer network for new articles on Flash.
If you are a developer you would generally find Flex more natural because it allows you to code your application. For this you can use the Adobe opensource Software development kit or Adobe Flash Builder The Flash Builder IDE comes with support for intelligent coding, debugging, and visual design and features powerful testing tools that speed up development and lead to higher performing applications.
For starting with Flex and Flash Builder, you can check out the 'Flex in a week' videos:
http://www.adobe.com/devnet/flex/videotraining/
As you go along the videos you can also check Flex language reference:
Alternatively, you can also use Adobe Flash Catalyst (still in Beta) to design your application. Catalyst will generate Flex code for you. This code can then be imported in Adobe Flash Builder where you can use Flash Builder Data centric features to connect to a database backend.
Learn about Flash Catalyst here:
http://labs.adobe.com/technologies/flashcatalyst/tutorials/

I want to learn Flex in Flash Build 4.7!!!

Can someone point me in the direction of a tutorial, or book on learning in Flash Builder 4.7? If one even exsists? All I can find is resources to learn in "Design Mode" which was discontinued in 4.7. I REALLY don't want to have to figure out how to translate the lessons...

Are you refering to an MXML file, or just a straight up XML file? In either case it should be the same. Comments are done with HTML style comment tags, like this:

I have verified and know that this is the case with MXML. In XML I haven't verified it, but unless Flash Builder 4.7 is handling XML in a radically different way than how most applications handle XML, it should work.
Also, here's a shortcut key that you would probably find useful. To comment something out, simply select what you want commented out, and then press CTRL-SHIFT-C and it will automatically comment out the selected section. And if you select a commented out section and press CTRL-SHIFT-C, then it will uncomment out the selected section.
Hope this helps.

Learning Flex for Web Development

Hello Folks,
I am new to flex. Previously i have been developing in PHP. I just thought of implementing a web based inventory management system in flex. Now in PHP, we have one html page that takes input and we re-direct it to a PHP page and it does the insert delete. But in flex, i can do all this on one page.. literally one page using view states.
So should i proceed with this approach OR is there an efficient way of page navigation in flex. Moreover, can we manage sessions in flex.??? Are there good resources for flex development for web like PHP???
Any help would be appreciated

States should generally only be used for small components that can change their UI in small ways.
In general for navigation in Flex, ViewStack is great, and also TabNavigator, Accordion, etc.
The following links give more info on this and also on using Flex with PHP and MySQL.

Learning AS3... curious about Flex..

Good morning..
I've been working pretty hard the last few months learning AS3.. I am starting to fell pretty competent with AS3 and am enjoying working with it.
I am now looking to implement a program that can be run through a Flex API.
How is Flex different than AS3?
Can anyone suggest some good starting steps to familiarize myself with Flex and start learning?
What is mxml and do i need to learn it for Flex?
thanks in advance,
J

I am newly introduced to flex as well and had to "try" to get famailar with it very quickly.
some good resources were learn flex in a week video training located here and also try lynda.com. I have not had to build anything in flex yet, but I had to have a good understanding of how some flex stuff was built and both those resources gave me a pretty good understanding of what flex is, what it does and how to use it.
mmxl is just XML so if you are not familar with XML go to wc3 schools look it over then ehad to the above link.

Advanced Flex learning

Hello,
I'm learning Flex 3 and now have basic Flex understanding.
Currently read "Learning Flex 3" by Alaric Cole, but there are only
basics in this book.
What books can you, guys, recommend for advanced
studies?

The best thing you can do is to go through these FlexBuilder
help topics and all their sub-topics TWICE. It will take several
weeks, but if you go through all this material TWICE, copying and
compiling all the sub-programs, you will extend your knowledge
sufficiently.
Flex Programming Elements
User Interfaces
Advanced Flex Programming
Data Access and Interconnectivity
Application Design
Application Development
Application Deployment
Custom Component Development
MXML Custom Components

Flex Learning Paths Beta

Here's a few initial thoughts.
First off, your intention is commendable. I'm very pleased to
see what I'd almost describe as a professional development tool
encapsulating what Adobe believes as the quickest path to Flex
mastery. It's clean, well thought out and a nice aggregate of
materials relating to learning Flex. I appreciate the filters of
Architect/Programmer/Manager and the sub-filters of Data Driven /
Customizing etc.
I am committed to getting a thorough understanding of Flex
and at a glance - this looks perfect. Of course, I consider this a
supplement to the mountain of books and tutes I've already
assembled.
Finally, feedback. I want this as an AIR app - on my desktop,
slightly repurposed as a "To DO" list. I want to be able to check
off items as I complete them and I want to have the capability to
add minor notes of my own to each task. The ability to add links to
additional resources found online that relate to the task/subject
matter would also be beneficial.
Again, looks to be an very helpful tool with an ambitious
agenda. I'm sure I'll have more to say as I move through it.
Thanks
Side Note: Videos are playing fine on my end

i would say it depends on which adobe products you learned to
tell how well it will translate. if you know flash/actionscript, it
should not be too bad. javascript and actionscript are both in the
ECMAScript families, so if you've not seen actionscript, but you
know javascript, it will be familiar.
also, it depends on how complex the project is. i came from
java-land (10+ years) and it's been a bit of an uphill climb
because our project is fairly complex. we have a real time system
in java to which we're connecting a flex client thru a proprietary
binary protocol polling every few seconds. we use the data grid
heavily and rely on some other key components, and we've had to
customize or override almost every behavior of TileList, DataGrid,
and ArrayCollection. we've had to disable a lot of the binding
features on the collection under the grid because we're updating
about 300 cells at a time.
of course, if you want to do a shopping cart (*the* flex
example application), you will actually find about 30 gazillion
implementations. that's a fairly static application with few
tentacles to server-side services. most examples online are pretty
trivial and i've not found a lot of use for them.
if your project is not too complex and you have some
object-oriented programming ability, it's not too bad a curve.

Learning in a Hurricane

I'd like to say my problem is that I'm really stupid but
insofar as I don't remember alcohol having had that much cumulative
effect please excuse if I seem to be ranting while simultaneously
seeking help. As background:
I came up with a business idea and knew fireworks/photoshop.
I "painted" mockups of the site front end.
The Flash developers I then hired to "make it work" failed
miserably to the tune of $250,000+ (hey, I never said I was a tee
totaller).
I learned SQL/SQLYog and designed the site database --
including as much business logic as possible in that tier.
The Adobe Solutions Provider contracted to simply connect the
"ends" also failed miserably to the tune of $150,000 I know, but
it's not as though I still drink that much anymore).
I set out to learn Flex and found MXML easy but ActionScript
incomprehensible.
Perhaps due to this efforts to connect to my MySql datasource
have progressed slowly.
Frankly though, the learning resources at each step along the
way have been, well, lets call it "convoluted". Despite numerous
book purchases/tutorial exercises and nearly infinite web research,
the abundance of options, terminology, product upgrades etc. is
more than half "the problem".
Thus I proffer the following primarily for fellow noobs --
though also in the sincere hope of finding mentor(s) to speed my
own on-going learning curve (corrections/comments/advice actively
sought):
Flex (which is really Flash which is really ActionScript)
provides the best (or at least incontestably most mature) front-end
(or "View" tier) available today.
Databases are (until they become immensely large)
interchangeable on the backend (or "Model" tier).
Communicating between the two is the "Controller" tier and
good software design practice suggests breaking application code
into (self-contained) "modules" saved (roughly) in separate Model,
View and Controller folders (with further subfolders from there etc
-- please don't ask me what Cairngorm is).
In Flex, the controller is essentially code which listens for
events (such as a mouse click on the "Google Search" button) and
then dispatches "results" (say "search terms" to the database,
whereupon it listens for that response and sends it back to the
display page).
Straight forward enough so far right? OK, well a big hurdle
is the database needs an interpreter, the main applicable being PHP
or ColdFusion. Primarily because Adobe seems committed to
integration, CFusion is what I've chosen (but be advised each is a
new programming language/skillset to master in addition to
IIS/Apache setup and IMHO is best learned distinct from Flex).
Meanwhile back at the ranch, data can be received by or sent
from Flex via <mx:HTTPService> OR <mx:WebService> OR
<mx:RemoteObject>. The first two require conversion from/to
XML and so are more generally available but also "heavier" (costing
bandwidth and CPU). Thus I've chosen the latter, especially due to
extra/better features between it and ColdFusion.
Specifically CF 7.02 and 8 have "Remoting" built in. This
allows Flex to "see" the dbase and is what the CF wizards in Flex
make use of. Additionally there are CFusion "add-ons" (don't even
ask Adobe evangelists the product names) which provide scalability
and Server-push capability (say for building a Flex Instant
Messaging App).
Yet despite this CF-Flex interactivity, ActionScript best
practices argue for Object Oriented Programming. I'm beyond my
comfort level now but I think this breaks down to databases
delivering information as a "set" (i.e. 50 of First, Middle, Last)
whereas OOP ideally would have a PERSON "class" (all of which must
have attributes of First, Middle, Last) which it then would make 50
"instances" of to display on the UI.
These "classes" are defined or extended via ActionScript
(note that MXML is really just preformed AS "classes" and a
specific data-exchange benefit of AS3 is "strong typing") and
specifically the "Controller" tier needs to be written in AScript
(i. e. beyond the cfcs and AS classes the CF/Flex wizard creates
for database interaction).
As above, I hope this helps some of you out there, obviously
I'm still struggling in some respects myself and welcome additional
links and any other feedback -- especially all those who wouldn't
mind my emailing them every now and then with a "stupid" question
(possibly arising from my "University Days").

I am not sure what your question is here,
but I could suggest using a java backend using LCDS,
Blaze-DS, WebORB or red5 to support amf3 using remote objects.
As it sounds like that your DB is fairly complex, why not go
for a better DB like PostgreSQL or something commercial, PostgreSQL
can withstand higher loads while keeping it's performance (my
experianc, not tryinto to flame here), see
http://tweakers.net/reviews/657/6
(PG 8.3 performs much better even).
Then try to write POJO's in structured classes, make modules
in flex Actionscript is really not that bad, but you need to handle
it as a scripting language so keep it small.
Appart from that, which I had the drink with you :)
cheers,
Ries

Flash/Flex Buider versions & Error #1053: Illegal override

I recently upgraded to FlashBuilder 4, rebuilt my FlexBuilder 3.2 apps, and continually hit "Error #1053: Illegal override" runtime errors. I had to rebuild all dependent libraries with FB4 to get things to work.
Based on http://bugs.adobe.com/jira/browse/SDK-14464 (second comment from bottom), it appears that the Adobe best practice is that all code should/must be compiled with the same version of FB.
Does anyone know of any way to workaround this limitation? Furthermore, how is it possible for 3rd party vendors to provide Flex libraries without also providing source code?
Jeff

I am getting this message and updated my flash player to
version 9.0.45 and now flex is saying that it can't find a valid
version of the flash player and that I may need to install flash 9
or reinstall flex. I did both of these and it did not work. Does
anyone have any suggestions. I have been complete incapable of
setting up a coldfusion flex development environment on xp that
works. I installed CF into IIS and it is working fine. I have
installed FB 2 as a default install. I then went step by step
through this tutorial (
http://www.kylehayes.info/captivate/QueryToDatagrid/QueryToDataGrid.htm)
and ran the application and it blows up. I would REALLY like to
learn flex and begin to develop some applications but I can't get
my apps to run because of this stupid error. Any suggestions. Bug
fixes. Anything???
Thanks,
Jason Presley

Flex for Web/Graphics Designers

Hi,
I am a hard core web graphics designer and have worked
extensively in designing websites and web applications using CSS
and HTML. I have also created interactive presentations in Flash
but to the basic navigation level and not advance action scripting.
I do not have much knowledge in programming.
I would want to know how Flex works for web graphics
designers? What capabilities I will have to build into myself so
that I will be able to work on Flex and also propose solutions
while discussing with clients and developers?
It will be great help if any of you can guide me to become
and expert with Flex?
Regards,
Amit

Hi Rahul,
Thanks for the link. Let me go thorugh it and I'll get back
to you on that.
The reason for getting into Flex is: I feel it is related to
Flash and its really been a long time since i was deciding to get
into some programming (especially actionscripting). After
introduction of Flex, i thought it will be good to learn Flex as an
upcoming medium in creating RIAs by using actionscripting. In a way
I will get a chance to clear my fundamentals of programming which I
am looking forward to as the first step to learn the logic of
programming. Correct me if I'm worng.
I am open to doing courses also if needed. Please help me in
that.
Regards,
Amit
