Oupa! Finally the day was yesterday ...
But those who deceive themselves thought that the examination would be easy, took only 11% more than the minimum to pass ... I passed the exam, but if I thought it was well prepared for the exam, deceive yourselves! It was not.
An examination with a strong focus on Adobe AIR, about 10/12 questions, since events drag / drop, databases, files ... finally, by security sandbox AIR, Air and Air Badge installer ... To my amazement even asked the MAC as it was possible to uninstall an application AIR choosing 2 of 5 answers ...
Undoubtedly many questions that can use trick, mainly because they are written in a way and the responses to another, ranging from answer to answer just one or another detail.
The questions are even prepared to really see if we're inside the flex, and venture to say that it is quite demanding, with questions like:

The title says a lot. This time the adobe announces a new world with regard to their projects for the desenvoolvimento of RIA's.
After launching the Creative Suite 4, which are filled with news and many of you get the hat, has announced major news event in its MAX, which is really the name Juz, among which is the abandonment of Thermo. Do not be scared, now calling itself Catalyst and is closer than ever to have its official version released.
Max was even released in its version for MAC (hmm ...) but will soon be available for windows (hopefully).
Along with Adobe Catalyst also has a version of Flex Builder 4, which already has an "official" release that was distributed at the event.
Along with these applications were also released some new labs in the adobe, such as:

This is without doubt a big headache in my studies of Flex. How should I noticed I love PHP and Flex, and therefore usually in my applications using the databases always use the AMFPHP to communicate with the Flex Backend (php + services of databases), but curiously until the exam Certification of Flex 3, the adobe "pull to its own domain" and introduces a topic that is worth 16% of the test, and should not go there without the minimum notions of such services, and therefore put hands to work and decided investigate this as a bit of lcds.
As I have no experience with the lcds, if any concept / information is incorrect do to please leave a comment indicating the error / solution / tip.
Getting started:
- What is the LCDS - LiveCycle Data Services?
Basically it is an "application of the second camanda", ie serves as the communication between the first layer (front end) and a possible third layer (backend), which has as main objectives:
- Dealing with large amounts of data
- To establish communication between the client and server part of an application
- Helping to get / get / store data via RPC (remote calls) and proxy settings
- Using tomcat to serve as a database server.
- Allow direct links to some databases without using language back-end (versions 2.5 +)

After a tutorial on how to use the filters available in flex, I now turn to some more interesting properties GRAFICAS well in flex and also blends.
Present in many graphics programs, also supports the flex mask, namely the use of a subject area as the "scope" of another, imagine having a rectangle and place a circle like mask that box, the end result will be the only area of rectangle surrounding the corresponding area of the circle, we can see that the following image:
This applied to flex is very simple to run, simply create an image, create a mask (which can be a canvas for example) and display the image that should apply to itself the mask (as a canvas mask.), See the code:

'm More a look at flex, I speak today of some filters and blend in the native's flex. In addition to the action script is very versatile in animation with respect to filters and blends Nor is anything behind, and a proof of this is the package filters available in the flex / flash, see:
- BevelFilter
- GlowFilter
- ColorMatrixFilter
- ConvolutionFilter
- DisplacementMapFilter
- DropShadowFilter
- BlurFilter
- GradientBevelFilter
- GradientGlowFilter
These filters have already talked to some tutorial in Action Script 3, and list examples of them all, starting with creating an image:

Continuing with my studies, I speak now to another point that certification will include Flex 3, interfaces, I speak of "definitions of class" as an interface.
In Object Oriented Programming, an interface is a type of document action script that allows state (not to define) the methods (functions) of any type of class. This kind of statement makes it very useful as it would separate the interface implementation of the projects in which media-large with a team of developers makes it very versatile our classes.
The main objective of the interfaces is to allow a programmer to identify the functions that are part of one or more classes, with a reference to them.
In general, imagine that we have 20 functions distributed in 3 classes within the same package, an interface will allow the following:
- Summary of all functions in a single file (interface)
- Rapid location of a particular function in our class
- Note the type of parameters received and returned by functions
- Easy to identify a group of programmers to implement the methods of a class / interface.
An interface does not behave like a class. As identified by the following properties:

As part of my studies for certification Flex 3, I review some points where I feel less at ease in the wonderful world of Flex, today I will begin with a point that still reserves a hard time understanding. I speak of MVC - Model, View, Controller.
The MVC is a pattern of either design or construction of architecture using the software. The use of this standard is very wide, and considers itself as the separate treatment of logic programming and graphical interface of the software that results in a tremendous versatility of application that makes it much easier to modify the visual aspect of the application or the code without creating dependence / allocation between them easily dealing with the communication between user, graphical interface and the code of our application.

A great news for programmers / developers to Flex / Air.
After the two weeks have decided to take the exam certification Flex 2, I read a good news today is that just in time to change my pa option, which is now the aim is to certify Flex 3, and that will be forthcoming.
I will now provide a bit of time to get acquainted with new topics and primarily with the AIR who never gave much attention to that soon I can feel prepared for the exam 
Anyone interested can see the details of the examination questions and example here
Currently only the centers of Person Vue provide the exam, you can see the centers here
As for the examination, there were some changes, among them the inclusion of AIR and the reduced number of questions to 50 in style multiple choice, where you need the minimum of 67% of questions correct to pass the exam.
Well, good luck to those who decide to take the exam, and good luck for me too

I have seen on several sites some interesting points that speak of AS3, but very few deals with the basic structure of a class and their types of components and functions ... well, went for my favorite feed'se looking for some articles that speak it, and how to expect very few, so here goes ... a tutorial on how to understand and construct the classes in AS3.

Placed on October 25, 2008 in: News After having launched the second part of my tutorial of action script 3 and announced the contest to reward with 3 copies of the full version, I announce the winners of the first 2 tutorial, who left his comment and trackback.
At first the lot would track mySQL, but as a matter of practicing and authenticity were made using random.org, so you can see the results and pictures showing now and then ...
