This is a more complex version of my previous example. This time in addition to making the Alert control’s text non-selectable, we use an embedded font for the Alert title, message, buttons, as well as edit the drop shadow, remove the rounded corners, and remove the button skins.

Top 10 Mistakes when building Flex Applications

Using an RIA framework to build Web 1.0 applications (aka. New technology same old stuff).

One of the largest challenges when moving from Web 1.0 applications to the RIA’s development paradigm is learning to think differently. Flex gives developers an advanced component library that allows for doing things that simply weren’t possible only a few years ago. Often, the power of Flex is missed, and the framework is used to implement more traditional Web 1.0 applications.

Building Web 2.0 applications is more than partial page refresh and rounded corners. For example, Flex developers should be using vectors to provide users a visual understanding of data, and advanced controls for a rich application flow. Stephan Janssen discusses this struggle recently with InfoQ.com:
As a Java developer, learning Object Oriented ActionScript and the UI markup language is really a walk in the park. The challenge however for (Java) developers is that we’re not designers, and with RIA technologies these two skills are very much needed.
Breaking standard browser experiences.

While Flex does provide an excellent platform for improving the user experience, it still important to maintain familiarity of things like the back button, book marking, and auto complete.

Flex 3 includes new Deep Linking features for back button support and book marketing. You can learn more at labs.adobe.com. There are number of components out there for implementing auto-complete. From the Adobe Exchange, you can use the AutoComplete Input component.

There are quite a few articles out there discussing Papervision3D and sharing source code, etc. but very few explain in plain English how to actually get started with PV3D.

Runtime expression evaluation in ActionScript

flexin — Thu, 24 Apr 2008 14:42:56 +0000

A simple Actionscript library that can be used to parse mathematical expressions: it has support for function calls, for variables and it is able to convert the expression into a postfix rappresentation if you may need it. The expression parser is quite simple and have been built manually following some concepts related to programming language compilers; it includes a Scanner (or lexer – however you want to call it) to tokenize the expression, a Parser that convert the expression into an Abstract Syntax Tree and a simple routine that evaluates that AST using a Symbol Table as evaluation context.
