This article, the first in a two-part series, provides a PowerBuilder 12.5 .NET developer with the foundational knowledge and skills to rapidly get up and running building PowerBuilder RESTful Web Service clients. Along the way I'll share with you a few tips and workarounds. Introduction PowerBuilder 12.0 .NET provided the ability to call SOAP-based web services using Microsoft's .NET 3.5 WCF API.

How I Arrived at This Ulitzer Blog

PBDJ Blog This note is to my many acquaintances and professional colleagues, I've been  around the PowerBuilder Sybase/Powersoft camp for more than 15 years.  For 13 of them I was lucky enough to be a trainer, traveling all over North America helping thousands of you build your coding skills and master the PowerBuilder platform.  Golly, I remember standing in front of more than 400 of you in at Techwave in Orlando introducing you to building web apps with PowerBuilder and the EAServer studio (anybody still doing that?).  During all my years at Sybase I didn't write much.  I was s...

Crazy Eights: Migrating a Legacy Application up to PowerBuilder 12 .NET

I grew up in a Brooklyn NY apartment building. As a young kid, one of my rainy day after-school pastimes was playing card games with the other kids in my building. One of the games we played was crazy eights. If you're curious about this simple card game, check out the Wikipedia description at http://en.wikipedia.org/wiki/Crazy_Eights Recently I was tasked with migrating a legacy application with distant roots in version 4, up to PowerBuilder 12 .NET. The trip over to version 12 Classic went fine with nary a hitch. The ride over to .NET was not too bumpy either. But then I start... (more)
