The development of the Web DataWindow is a great technological advancement.
It's extremely helpful in moving an existing PowerBuilder application to the
Web. Most PowerBuilder applications contain many DataWindows for the various
screens and reports. The ability to quickly render these controls as HTML in
a browser is a huge timesaver.
The update process of the Web DataWindow is one of the most frequently posted

applications. Th... (more)

As Larry wrote about in last month's column (PBDJ, Vol. 12, issue 8), we also
have to choose whether to include multiple a... (more)
Now that Steve has discussed frameworks and building from scratch, I'll cover
some things to help you avoid writing duplicate code.
Remember that the purpose of these articles is not a tutorial with
step-by-step instructions but a guide to assist in the design and development
process. Our goal is to help new developers get started in the right
direction and to avoid pitfalls. This month's... (more)
