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.

Hello, together,
does anybody know how to change the look of the Flex Builder 3 in black? Is there any themes or additional style for its look? The editor background is already changed.
Thanks in advance

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.

How can I advance in learning Java?

It seems to me that there are so many branches in Java! Having completed basics of Java, I don't understand what to learn next. There are so many topics - JDBC, Enterprise JavaBeans, J2EE, Java Network Programming....... and many more!
Any kind of suggestion from the experts would be much appreciated.

They are really only API's, you don't need to learn them until you require them in a project. Your basic java knowledge and google should be more than enough to get you going with most Java API's.
J2EE is somewhat more advanced material, containing enterprise javabeans and web technologies such as JSP and servlets. I suggest you start learning that, as the whole world seems to have caught the internet bug. Most applications developed today appear to be webbased or at least utilizing the web (such as through SOAP).

Advanced Flex / Pixel Bender interactions

Hello,
I've been looking through the documentation on both Pixel Bender and Flex, and I'm trying to figure out if this even possible:
Basically I start out with floating point image data in a ByteArray and I'd like to run a Pixel Bender filter or shader job on the data in floating point, then convert it to 8-bit / channel RGBA on the output.
I know I can start with a 8-bit BitmapData and use a Pixel Bender shader to produce a new 8-bit BitmapData. Or I can start with a floating point ByteArray, use ShaderJob to compute a new floating point ByteArray. Can I use ByteArray input and output to BitmapData? Put another way, do the input and output classes/dimensions of a shader job or pixel bender filter have to match? I'd like to take advantage of the fact that when using a BitmapData object, Pixel Bender (or Flash), converts the floating point Pixel Bender data to 8-bit for you automatically. It would also save me the trouble of unpacking a linear list of floats into a 2-dimensional image with setPixel32() calls.
Thanks all.

Hi David -
Thanks for those examples. The audio visualizer is pretty cool, but looks like the author witheld the source code for us to look at .
I did find another blog posting that's helpful too - converting a BitmapData object into a Vector of RGBA floats with Pixel Bender:
http://webr3.org/blog/general/pixelbender-is-more-useful-than-i-assumed/comment-page-1/
I'll see if I can figure out going backwards.
I'm curious if anyone could shed light on what's going on with memory under the covers. I found another blog post that treats a Vector as if it's a 2-dimensional object like an image:
http://blog.robskelly.com/2009/02/using-pixel-bender-for-math-in-flashflex/
This raises questions about what do the width and height input/output parameters actually control if you can treat a flat Vector as an object with width and height? Does anyone know? Does that only work with Vectors? What about ByteArrays? Does this basically mean that width/height are only convenience parameters and you could put any 2 numbers that multiply to the size of your data? How does this affect the input type inside the shader (image1 vs image4)? Why does Rob Skelly's example above even work at all?
I'll hack away at trying to get stuff working, and re-post if I figure something out.

Flex learning curve - is it steep?

Hi Everyone,
I have only Adobe GoLive experience, and even then it is just
general web development.
I have no Flash development experience. Am I getting into hot
water by wanting to start developing in Flex? Our goal is to make
e-commerce sites.
I see products like ZoomFlex and wonder if I should fork out
the $$ and start with it.
Please any comments are very welcome. Even if you want to
tell me I'm crazy. I don't know at this point, that's why I'm
asking.
Thank you,
Paul.

Short answer, yes. Especially given the fact that you do not
have any flash/actionscript experience. I would not say you're
getting into hot water by wanting to start using flex, unless of
course you have a tight deadline for your e-commerce site.

Getting started with Flex ...

Hi All,
I've been looking a Flex over the last couple of weeks and have managed to setup a couple of basic projects that can read data from a mySQL database etc... However when it comes to understanding some of the more advanced frameworks and options to use with Flex it starts to get very overwhelming.
Does anyone have any pointers/suggestions for good material (online or books etc) to start with Flex. I come from an Oracle Forms development background and in terms of setting up an application with a connection to a database Oracle Forms seems to a lot simplier than building a Flex database application (although the functionality of Oracle Forms as a lot more limited than Flex/Flash).
I have taken a look at a the book Enterprise Development with Flex: Best Practices for RIA Developers (Adobe Dev Lib)http://www.amazon.com/Enterprise-Development-Flex-Practices-Developers/dp/059615416X/ref=s r_1_6?s=books&ie=UTF8&qid=1319581262&sr=1-6 by Yakov Fain, Victor Rasputnis and Anatole Tartakovsky (Mar 30, 2010), however the very first code example in the book appears to be dated and I'm having trouble getting it to work and finding the appropriately dated source files for the example project.
I have also taken a quick look at Adobe Flex 4.5 Fundamentals: Training from the Source by Michael Labriola and Jeff Tapper (Aug 5, 2011) which appears to be a bit more recent, however I am not sure how much is covered regarding database connections to databases like mySQL and Oracle.
Any suggestions on the best learning materials available would be really helpful. At the moment it feels like I need to be an expert in Flex, MXML, ActionScript, Java, Spring, Hibernate, AMF, Maven, BlazeDS etc etc just to be able to create a simple database centric application (aarrgghh).
Ideally I would love to be able to find a recent tutorial that goes through the building a relatively advanced Flex database centric application, that includes information about building a database based login/authentication system (without having to use PHP), and database controlled/stored main menu system and a system for modular sub tabs/screens/programs within a main application.
Regards,
Leigh.

Thanks everyone for the replies. I guess I'm a bit lazy when it comes to reading up on a technology I am not familiar with :-) . What makes things worse is the Oracle Forms Builder IDE is very highly coupled to the Oracle database and therefore there is no requirement to know or understand the language or technology under hood (other than PL/SQL), Oracle takes care of that within the IDE and the Forms Java Bean (deployed by default with a middleware installation of Oracle application server).
@dwaynie Started working through the Flex in a week video training yesterday. Its really good and probably the best place for me to start as it goes over a lot of the assumed knowledge regarding Flex, MXML and AS (stuff I have probably glossed over up until now)
@Mansuro noticed that spring has a dedicated page on the Flex/Flash plaform site so I'll probably look into this more down the track. I guess the thing I am little confused about is that there are many examples online that integrate Spring + Hibernate + Maven + Java etc etc, I guess each framework has different features that the others don't and therefore all can be used at once, or does each one offer a completely different service? More reading is required here I think.

A query with respect to Flex 3 States

Hi ,
I am new to Flex3. states
I have started with a sample application , but i couldn't able to understand some of the things in Flex 3 States . Please help .
This is my sample Application what i am trying :
<?xml version="1.0" encoding="utf-8"?>
<mx:Application
    xmlns:mx="http://www.adobe.com/2006/mxml"
    layout="absolute"
    currentState="bad">
    <mx:states>
        <mx:State name="bad">
            <mx:SetProperty target="{label1}" name="text" value="Bad Day!"/>
            <mx:SetProperty target="{linkbutton1}" name="label" value="Go Good"/>
            <mx:SetEventHandler target="{linkbutton1}" name="click" handler="this.currentState='vgood'"/>
        </mx:State>
        <mx:State name="vgood" >
                <mx:SetProperty target="{linkbutton1}" name="label" value="Go Good"/>
        </mx:State>
    </mx:states>
    <mx:Label
        x="255" y="191"
        text="Good Day !"
        fontWeight="bold"
        fontSize="22" id="label1"/>
    <mx:Button
        x="255" y="98"
        label="Go To Bad Day"
        click="this.currentState='bad'" id="linkbutton1"/>
</mx:Application>
Please see the above code , It is working fine , but i am having some questions related to it .
Please tell me whether Is it possible to know under what state the Application is currently in ??
Thnaks in advance .

Okay fine , i will do that .
I am having one more question related to flex 3 states . That is :
Refering to the above program posted , in case if i need to change the current state , i am depending on this
            <mx:SetEventHandler target="{linkbutton1}" name="click" handler="this.currentState='vgood'"/>
Is it not possible to achive the above requirement using <mx:Property>
            <mx:SetProperty target="{linkbutton1}" name="label" value="Go Good" handler="this.currentState='vgood'"/>
(I have tried with this , but its not working , the mx:property is not accepting the handler attribute ) )
seems Flex learning curve is so big .

Is Flex 4 Training from the source any better than Adobe's own Using Flex 4?

I am preparing for the Flex 4 ACE exam from Using Flex 4. Is there a good reason for me to switch to the training from the source book?

Firstly note that F4TFS is in 2 parts, and although part 2 appears to have been published at the end of 2010, AFAIK it appears to be unavailable right now. I have read F3TFS, and am going through F4TFS at the moment. Using Flex 4, available free as a 32Mb PDF, is a very useful reference, along with the 12 or so other Flex books available free from Adobe. While Using Flex 4 is a reference (including plenty of example code), F3/4TFS is structured as a series of lessons, working on the same project (Flex Grocer shopping cart app) throughout. It touches on most aspects of Flex development, and is a great guide for beginners. If I have one criticism of the book, it is that a shopping cart example is going to be inherently dull- so if you have a low boredom threshold you will have to force yourself through the examples. I would still recommend it as a beginner's book, although in the real world you are unlikely to be using Design Mode much, except for throw-away prototypes. If you have a project you want to get started on right away, then you could just wade in and start coding using the Adobe documentation for help, but if you'd like to have an existing example, then F4TFS is for you.
When learning Flex its best to read as much as possible, so I'd widen your reading if possible to include the Flex 4 Bible, AdvancED Flex 4, Enterprise Development with Flex, etc, and the absolute shedloads of blog posts and examples on the internet.

Adobe Flex & DESIGN Recommendations ?

Hi Folks,
While I am a bit beyond scratching the surface in Adobe Flex 4 & AS3 usage and knowledge, I am looking to spruce up the look and feel of my applications. So, I am looking at and getting confused by a never ending alpha soup of various Adobe products - such as Photoshop, Illustrator, InDesign, Catalyst, etc.
Where do I start and what do I actually need in order to be able to spruce up my Flex App with some custom looking components, UI controls and logos ?
What are you using and what would you recommend for a noobish person like my self?
Thanks again,
VC

When I got Flex 2 certified, I found this software to be
fairly useful. The Flex 3 exam version is not out yet, so you might
consider getting the version for Flex 2, as it still should be
useful:

Advanced Datagrid - Summary Row without groupping

I need to make a datagrid with a summary row on top of it. It
works fine with the gropping tag inside of groupping collection.
But i don't need groups - i need only summaries.
When I white following code inside of Advanced - flex crashes
and tell something like "cannot null blablala".
quote:
<mx:GroupingCollection id="smallMetricsDataProvider"
source="{bigMetrics}">
<mx:summaries>
<mx:SummaryRow summaryPlacement="first">
<mx:SummaryField dataField="@type" operation="COUNT"
/>
<mx:SummaryField dataField="@budget"
summaryFunction="MetricsUtils.varianceTotalCount" />
<mx:SummaryField dataField="@raw"
summaryFunction="MetricsUtils.varianceTotalCount" />
</mx:SummaryRow>
</mx:summaries>
</mx:GroupingCollection>
What can you advice 4 me?
Thanks, Roman.

Fine, I found a way how to do it, using renderprovider 4
folder items with a null height =))).
It's a hack, the bad hack, i hope it wold be improved...
So, i have another problem - i want to get this summary
values. How?
Thanks, Roman.

Can Flex Travel?

Have and advanced flex question...
I have a vocal track and it needed tuning. Used flex pitch. Then I bounced the track (including the flex pitch).
So now I have a tuned vocal and a muted original.
Next I do a bunch of flex timing stuff on the tuned (bounced) vocal.
Next client comes in... "timing is great but I hear the tuning".
My questions is can I take the flex timing information and apply it to the oringinal (not bounced) vocal.

Lisa,
If you have an Intel iMac (as I would imagine based on your posting in this section) then it does have an auto switching power supply and should work fine on a European power socket (obviously you will need a new power cord or an adapter plug to make the pins fit.)
You can view Apples article on power supplies/voltage settings as well as a list of older iMac compatability (if you don't have an Intel model) here:
