PowerBuilder 12.5 introduced a number of significant enhancements to web
services support, both for creation and consumption. In particular, the
following were introduced as new features in PowerBuilder.NET:
WCF client proxy WCF service target REST client proxy
We're going to look at what those new features provide and how to use them.
We're also going to look at how we can package some of that functionality so
that it can be used from PowerBuilder Classic applications as well.
Windows Communication Foundation (WCF)
First though, some background. When support for a web service client was
first introduced in PowerBuilder 9, it was done based on an open source
library called EasySOAP. There were some limitations with that
implementation, primarily because the EasySOAP library only supported SOAP
1.1, was limited to XML over HTTP transport, and provided no support for
The PowerBuilder 12.0 beta has officially started. It's pretty hard to
overstate the magnitude of the changes that are taking place within
PowerBuilder for this version. As a result, it's more important than ever for
as many people as possible to participate in order to get the most amount of
feedback as possible back to Sybase. It's going to be a lot easier to let
Sybase know there's a problem with a feature now before the "die is cast" and
it's easier for them to fix than to wait until after the release to find the
problem, and then have to wait for an EBF for a correction

There's been a lot of discussion since Microsoft's BUILD conference on the
fate of Silverlight. (Something that is an issue for us because Sybase was
originally looking at supporting it for web app development in PowerBuilder
15.) Contrary to what a number of the pundits and would-be pundits have said,
I don't think it's quite accurate to say that Silverlight is dead in Windows
8. I think it's more accurate to say it's evolved.
As background for those who haven't been following this closely, Microsoft
announced that the Windows 8 operating system would support two kinds of
One of the long awaited features introduced in PowerBuilder 10.5 is support
for contemporary (aka Office XP) menus and toolbars. The first difference
you'll notice is that the flat contemporary style and new icons are used
extensively throughout the PowerBuilder IDE itself (Figure 1).
New Menu Options
The next thing you'll notice is a dizzying array of new options in a new
"Appearance" tab page in the Properties pane for the top level menu item.
What adds to the dizzying effect is that the menu options (Figure 2) and the
toolbar options (Figure 6) are all combined on the same tab ... (more)
This year TechWave 2005 took place at Caesars Palace in Las Vegas. For those
of you who didn't make it, the following is a recap of the events, with a
couple of thoughts and suggestions thrown in.

Test Your Sybase Knowledge Gameshow
Four TeamSybase members (Millard Brown, Terry Voth, Mike Nicewarner, and
myself) do battle against a team of Sybase employees. Each team took turns
answering multiple-choice questions off a Jeopardy-style game board. Fifty
percent of the questions were related to Sybase engineering and the rest were
from other walks of life. There wer... (more)
