Top Stories by Arthur Hefti

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 end I will cover PowerBuilder WinForm and PocketBuilder as they could be solutions for applications that are not always connected. This article doesn't cover all the possible techniques (Appeon comes to mind if you're fine with an IE-only solution or WPF XBAP used for no-touch deployment of W... (more)

Encryption in PowerBuilder

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. Short History 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)

PowerBuilder - The ClassDefinition Object

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 their content. 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... (more)

Using PowerBuilder Assemblies in .NET

PBDJ Feature Story There's a lot of "legacy" PowerBuilder code that you might want to access from .NET applications or perhaps PowerBuilder has some superior functionality that you would like to make use of in a .NET application. Think about how easy it would be to create a report in PowerBuilder with a DataWindow. Of course, PB can provide functionality through Web Services (see my article "Prognos with DataWindow.NET 2.0 and PowerBuilder 11 Web Services" in PBDJ some time ago) but this has its limitations. In the article "PowerBuilder 11's .NET Interoperability" in PBDJ, John S... (more)
