The DropDownDataWindow (DDDW) edit style is one of PowerBuilder's outstanding
features. Yes, I know there are a lot of new and exciting capabilities in the
upcoming release of PowerBuilder, but in this article I'll try to solve some
of the current problems with the existing features that are popping up in
nearly every project I've seen.
Here I'll focus on DropDownDataWindows, including:
How to get started with DDDWs Filtering DDDWs without losing the display
value in other rows Catching the collapsing of a DDDW Trapping the cursor
keys in a DDDW Autocomplete DDDW values
The basics are well covered in the PowerBuilder User's Manual, but if you
still have problems defining them look at Figure 1. Click on the column you
want and its edit style (yes, click on edit on the properties) as DDDW
(choose DropDownDW as Style Type).
Next, choose your DataWindow, ... (more)
An enterprise portal is the converged "hub" of multiple, complementary
information management solutions, including document and content management,
information search and retrieval, knowledge management, team collaboration,
workflow, and business intelligence.
In this article, we describe what an enterprise portal is and give you a
brief overview of Sybase Enterprise Portal. Then we take a closer look at the
portal and go over some of the installation requirements and steps for the
Information Edition of the portal. We also delve into how to use a portal and
build components (ca... (more)
The Web Services Description Language (WSDL) makes it possible for automated
code-generation tools, like PowerBuilder 9 with its Web services wizard, to
simplify building clients for existing Web services.
In my previous article "Axis" (PBDJ, Vol. 9, issue 8) we discussed the basic
steps involved in implementing a Web service using Axis, EAServer, and
PowerBuilder 8. Now we'll explore the technologies that make it easier to use
Web services that have already been deployed.
What Is WSDL?
WSDL is an XML-based language used to define Web services and describe how to
access them. For... (more)
There is (still) a growing market for Java development tools. This is a good
thing, but also a big problem, since I don't have a plug-in for every IDE for
my secret love: Sybase EAServer. It's not fun to build a .jar, .war, or .ear
in the IDE, then fire up the Jaguar Manager and do the boring "import by
hand" thing. What is the solution?
The solution is Jakarta Ant (http://jakarta.apache.org/ant/index.html).
Ant is a build tool that uses Java technology to perform all build-related
tasks. Since it's based on Java technology, it's a cross-platform build tool
that works anywhere. A... (more)
While writing one of my PowerBuilder 9 book chapters, I suddenly had an idea.
Wouldn't it be great to use PowerBuilder as a WAP front end? This would be a
cool application for Pocket PowerBuilder too (most of the new devices have
My first thought was that this might not be so easy. WML is based on XML -
PowerBuilder 9 offers good XML support - so not a problem here. No, the
problem might be the creation of the controls. Hmm, I had to dig around a
little bit and see if this could be a problem. Wait, I played around with the
WinCE API with PocketBuilder a few wee... (more)
