Top Stories by Paul Horan

When Sybase first released the Unwired Platform in 2008, it was intended to be a complete end-to-end development environment for mobile applications.  SUP developers would create the middle tier components (a.k.a. Mobile Business Objects), and the client application executables from a single, integrated Eclipse-based toolset.  There was a "PowerBuilder-like" 4GL screen painter, called the Device Application Designer (or DAD), that compiled down to native Blackberry 5/6 or Windows Mobile 6.5 applications.  (Yes, it's hard to imagine, but there was a time when iOS devices were not allowed to play in the Enterprise Mobile Application playground...) Several market forces emerged around that time and started to cast doubts on the wisdom of the "complete end-to-end" strategy.  Those were (in no particular order or importance): The release of the iPad, and overall growth o...

Source Code Control

Every software development project of any significant size or complexity has a requirement for controlling the source code asset. PowerBuilder is capable of integrating with any third-party Source Code Control (SCC) tool that implements Microsoft's SCC API. However, the fact that PowerBuilder stores its code inside PowerBuilder Libraries (PBLs) and not as individual ASCII text files adds a layer of complexity to that integration. The release of PowerBuilder 8.0 in 2001 brought with it a new set of challenges in the form of a completely redesigned interface with SCC providers, inc... (more)

OData Support in SQLAnywhere 16.0

OData is quickly becoming the Lingua Franca for data exchange over the web.  The OData standard defines a protocol and a language structure for issuing queries and updates to remote data sources, including (but not limited to) relational databases, file systems, content management systems, and traditional web sites.  It builds upon existing Web technologies, like HTTP and RESTful web services, the Atom Publishing Protocol (AtomPub), XML, and Javascript Object Notation (JSON). SAP and Sybase iAnywhere released SQL Anywhere version 16 in March 2013, and it had many cool new featur... (more)

StarTeam 5.1 by Starbase

Source code control (SCC) has become a "hot topic" lately, especially after PowerBuilder 8.0 was released, as it contains a wholesale revision to its interface with third-party SCC tools. PB8 now leverages the full functionality of Microsoft's SCC API, and is much more tightly integrated with the SCC repository. There are now over a dozen commercially available SCC tools that implement the SCC API, and choosing the appropriate tool for your organization is not a trivial task. The scope, features, and functions of these tools range from the "bare bones" approach of the open-sourc... (more)

Understanding WPF and the XAML editor in PB12.NET (part II)

In my previous post, we took a closer look at the XAML and WPF design capabilities of PowerBuilder.Net (AKA PB12), and actually began to construct a sample calculator application.  I’m using this MSDN sample as a design guide, which was 489 lines of C#, not counting the XAML.  The previous posting got us through the basics of the window and gridPanel layout, and we were just about to start writing some PowerScript to get the calculator working.  Let’s continue that discussion now!   Step 4: Analysis and Design work I’m one of those developers that likes to spend some time in the ...
