In the first article we presented a some theories about the ClassDefinition
object and were able to show the libraries of a PB application in a treeview
control. This month we'll read the objects from the libraries and inspect
When a user expands an entry in the treeview, we check to see if it was
expanded once already. If it was, we don't take any action. We code this in
the itemexpanding event of the treeview control, where we get the clicked
treeviewitem by calling This.GetItem.
If it wasn't expanded already, we check to see if the level of the
treeviewitem is equal to two, which means we're expanding a library name. We
could create an NVO to include all the logic for parsing, but for
demonstration purposes, I want to keep things simple. We define all the
functions we need on the window itself, but use arguments to refer to the
controls. This wil... (more)
Last year I wrote an article in PBDJ describing an ASP.NET project that was
done with DataWindow.NET in the browser ("Prognos" Volume 14, Issue 4) and
PowerBuilder Web Services in the back end. The front end consisted of an
intro page, two data entry pages, and one page with the result.
The front end was rewritten in a couple of other technologies to test
different ways to create browser-based applications. This article covers
solutions that run in different browsers and on different operation systems.
I will also look at PowerBuilder 11.2 Webform although it is IE-only. At the

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)
