Preface

General

This lesson is part of a series of tutorial lessons dedicated to programming with Adobe Flex. The main purpose of this lesson is to supplement the earlierlesson titled The Default Application Container - Flex 3 and Flex 4 with more information about the Flash Builder 4 IDE as well as information about the FlashDevelop IDE.

Adobe released a new product named Flash Builder 4 in March of 2010 and immediately removed all, or at least most of the references to Flex Builder 3 from their website. Those references that were not removed were converted to references to Flash Builder 4. For example, the link (see Resources ) that previously opened an Adobe page for free downloading of Flex Builder 3 (for educational use) now opens a page for free downloading of Flash Builder 4 for educational use.

What is Flash Builder 4?

Flash Builder 4 is an apparently upgraded version of Flex Builder 3 with a new name. Flex Builder 3 was based on Flex version 3, while Flash Builder 4 isprimarily based on Flex version 4. However, Flash Builder 4 still supports Flex 3 in addition toFlex 4.

Regardless of how you choose to get there, the objective is to create swf files that can be executed in the Flash Player. Flash Builder 4 is only one ofseveral different ways to create applications that will run in the Flash Player.

The Flex 4 SDK and Flash Player 10

In conjunction with the release of Flash Builder 4, Adobe also released a new version (version 4) of the free open-source Flex SDK and a new version (version 10) of the Flash Player.

Flex Builder 3 was based on Flex 3 and required Flash Player 9 (or later) for execution of the swf files produced by compiling a Flex application.

Flash Builder 4 is primarily based on Flex 4 and requires Flash Player 10 (or later) for execution of the resulting swf files.

Flash Builder 4 supports Flex 3

Fortunately, Flash Builder 4 still supports Flex 3 for backward compatibility. I will show you later in this tutorial how to use Flash Builder 4with Flex 3.

Should you use Flex 4?

If you are using Flex to create web applications in a professional capacity, you should probably become familiar with Flex 4. It appears to provide some features thatare not available in Flex 3.

More powerful but also more complicated

Flex 4 is more powerful than Flex 3. However, Flex 4 is also more complicated than Flex 3. In some cases, Flex 4 also appears to create much larger swf filesthan Flex 3 for solutions to the same problems. Therefore, I suspect that some developers will not make an immediate switch to Flex 4, and that Flex 3 willcontinue to be commonly used for a few more years.

In economics, a perfect market refers to a theoretical construct where all participants have perfect information, goods are homogenous, there are no barriers to entry or exit, and prices are determined solely by supply and demand. It's an idealized model used for analysis,

What is different between quantity demand and demand?
Shukri Reply
Quantity demanded refers to the specific amount of a good or service that consumers are willing and able to purchase at a give price and within a specific time period. Demand, on the other hand, is a broader concept that encompasses the entire relationship between price and quantity demanded

Economic growth as an increase in the production and consumption of goods and services within an economy.but Economic development as a broader concept that encompasses not only economic growth but also social & human well being.

it is a curve that we get after connecting the pareto optimal combinations of two consumers after their mutually beneficial trade offs

In economics, the contract curve refers to the set of points in an Edgeworth box diagram where both parties involved in a trade cannot be made better off without making one of them worse off. It represents the Pareto efficient allocations of goods between two individuals or entities, where neither p
