IT projects closely follow the path of technology. .For example, the number
of Java/XML/HTML projects is increasing, replacing PowerBuilder or
VisualBasic systems developed just a few years ago. And developers are asking
themselves the question: Do I have to write the same app from scratch? Again?
Integrating existing systems developed in previous millennium environments
with the Internet is a costly and difficult task. The other approach would be
to "convert" existing applications to native Internet technologies.
Sound complex? It's not. Legacy systems contain rich metadata, although in a
proprietary format such as PowerBuilder's PBL or VisualBasic's FRM files. All
graphic controls - list boxes, buttons, labels, and so on - show up in the
metadata with all their positions, sizes, colors, and other attributes.

Rich Internet Applications are perfect for consuming enterprise services. As
SOA evolves toward reusable components that can be accessed inside and
outside of the corporate intranets, they need to provide outside developers
with customizable pre-built components that can be easily integrated in
composite applications. Adobe's Flex/Flash platform offers unique
opportunities in both richness of the environment and global deployment
In this session we will uncover all the layers of successful SOA integration
for RIA applications - including communication, customizatio... (more)
From Farata Systems Flexblog
About a half year ago I made few comments in a Flex mailing list regarding
tricks I like to use when developing large Flex 2 applications. SInce then I
have been receiving steady stream of emails - once every week in the
beginning, up to few per days lately. They are asking for information from
the upcoming RIA book we are writing. Apparently, there are quite a few
developers that a) become impatient if the build takes more then 5 seconds,
and b) are concerned that their application will be delivered to the users
with similar attention span that co... (more)
Browser-based applications are widely used and we like the fact that we can
access them from anywhere. But from the users' perspective, the productivity
level of Web applications still doesn't approximate the productivity of
desktop programs. The good news is the gap is closing: the accumulated
potential of multiple technologies has boosted a whole new breed of
HTML-based apps that are as powerful as the desktop ones. Meet AJAX.
What Is AJAX?

In Part 1 (CFDJ, Vol. 8, issue 10) we introduced the destination-aware grid,
formatters, and renderers. In this article we are continuing our discussion
about datagrid renderers and...
RadioButtonGroupBox as Drop-In Renderer
We can apply similar techniques to RadioButton controls. The following code
snippet suggests how the group of RadioButton controls can be used as a
drop-in item renderer (and editor). Instead of an onValue/offValue pair, we
are introducing an array of options (we could have gone further and upgraded
to , which is similar to the Bu... (more)
