Zürich, 29. März 2014 – Per sofort ist CATTOR mit Anbindung an das Open Source Dokument Management System agorum core verfügbar. Alle Anhänge, Briefe und aus CATTOR versandten E-Mails werden zusätzlich ins DMS gespeichert und sind dort z.B. über den Browser aufrufbar.  In CATTOR wird pro Aktivität definiert, wie lange ein Dokument in der Datenbank verbleiben soll.

PowerBuilder .NET Web Services with Various Front Ends

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 ... (more)

The New Generation of Decompilers

The latest development technologies rely on intermediate languages and can be decompiled. PowerBuilder is no exception. In this article, we will address the risks posed by decompilers. We will also discuss what can be done to protect against the possible negative results of decompilation - whether you create in-house applications, commercial applications, or are using these applications for your business.
