So you think, "Why bother using PBDOM?" Well, you can use PDOM to manipulate
elements in an XML document. That means you can move elements in a document
or from one document to another. You can add elements to a document or delete
them from a document. And, with a little coding, you can import nested XML
data into a DataWindow.
With the XML capabilities in the DataWindow introduced with Sybase's
PowerBuilder 9, it's possible to import and export data very fast and easily.
You might have glanced at the PBDOM definition in the PowerBuilder help and
figured it looked hard to handle but, fear not, I'll introduce you to PBDOM
and give you some code samples.
Importing & Exporting with DataWindows
Starting with PowerBuilder 9, the DataWindow can import and export data in
XML. This powerful feature lets you exchange large amounts of data very fast.

The ClassDefinition object was introduced in PowerBuilder 6.0 a long time
ago. It allows you to retrieve information for an object at runtime. Most of
us didn't pay too much attention to this object and it only attracts our
attention when we see it in the debugger.
In this article I provide an overview of the ClassDefinition object and
related objects and explain the most important properties of these objects. I
also include a step-by-step guide on how to build a simple object browser.
This browser has a limited functionality like the browser included in the
PowerBuilder runtime... (more)
Prognos is an application used over the Internet to determine if it makes
sense to apply for a scholarship. It's part of a program package used in a
couple of cantons (the equivalent of a state in the U.S.) in Switzerland to
manage applications for a scholarship.
The current version runs with DataWindow.NET 2.0 and uses PowerBuilder 11 Web
Services. To keep the installation slim it uses no database; instead the data
is stored in DataWindows or XML files. Prognos makes use of AJAX techniques
and accesses .NET classes from PowerBuilder for XML handling. Since it's used
in Switzerl... (more)
PowerBuilder TV hosts regular webinars to PowerBuilder related topics and
will broadcast its first session on April 8th at 10 am EST.
Arthur Hefti will present "Using PowerBuilder Assemblies with .NET" on
PowerBuilder TV June 15 2pm CET.
Keeping information away from curious eyes is a challenging task. For
example, you might need to encrypt data before sending it over the Internet.
Or you might be storing some information in a database that not even an
administrator is allowed to see. This article provides a brief overview of
encryption techniques and shows how to do encryption in PowerBuilder.
Encryption goes as far back as ancient Egypt. In 1900 B.C. the Egyptians used
a derivation of standard hieroglyphics to make a message more difficult to
read. The art of hiding messages improved over the centu... (more)
