Paul Harvey, the great American radio personality, would always conclude his colorful broadcasts with the quip "And now you know the rest of the story." For those of you not acquainted with Paul's broadcasts, here's a sample. If you get to about 3:40 in, you'll hear the classic remark. Paraphrasing Paul's tag line, in this article you'll learn "the rest of the story" about RAD Development methodology in PowerBuilder 12.5 .NET using a Referenced PB Assembly Target. I'll explain the technique and implementation steps using the open source PEAT PFC demo application. In a previous PBDJ article, "Slicing the Pie with PowerBuilder .NET 12.1 EBF Project Partitioning," I wrote about achieving Classic RAD-like build/test speeds in .NET WPF applications by configuring the Project object partitioning feature. This feature lets you logically carve up a large application into a... (more)

A Snap-In App Framework Using Dynamic PowerBuilder Assemblies (Part 2)

This two-part series examines and contrasts PowerBuilder .NET 12.5.1's new dynamic assembly feature with corresponding dynamic library functionality in PowerBuilder Classic. The discourse is presented in the context of a simplified yet practical use case. Part 1 presented the use case, reviewed pertinent PowerBuilder Classic dynamic APIs and presented a Classic PBD implementation. Part 2 introduces PowerBuilder .NET 12.5.1's Dynamic Assembly feature, reveals relevant PowerBuilder .NET generated assembly internals, and presents a PowerBuilder .NET use case implementation. Along th... (more)

Breaking Platform Limitations

One of the innovative new features in the PowerBuilder 12.5.1 release is its ability to deploy PowerBuilder .NET code to run in 64-bit mode on 64-bit Windows platforms. In this article, after gaining background and perspective on 32- and 64-bit memory management and .NET deployment models, you'll explore the internals, strengths and limitations of this new feature. Introduction Almost all current server, desktop and notebook hardware platforms have 64-bit processors. Almost all current versions of Windows operating systems support both 32- and 64-bit platforms. With the 12.5.1 rel... (more)

Writing to the Console in PowerBuilder 12.5 .NET

Yesterday I taught an intro to PowerBuilder .NET 12.5 session.  Part of the presentation had me comparing the.NET IL code inside an assemblies generated from code written in C# and PowerBuilder. The C# code, after performing a simple arithmetic calculation echoed results to the console using these two lines of code namespace CalculatorExample { class Program { static void Main( )   { Calc c = new Calc( );  //create the object int ans = c.Add( 10, 84); //call the method System.Console.WriteLine("10 + 84 is {0}." , ans); System.Console.ReadLine( ) ;    } } class Calc {   //define a wrapp...
