PowerBuilder

An Updated History of PowerBuilder

Wed, 03 Sep 2008 11:04:00 EDT

I have been asked many times by various clients, students, and the IT curious about PowerBuilder: When did Sybase develop the product and how did it evolve? I keep telling this story and answering e-mails on the subject. I am now to the point where I have decided that I should have PBDJ formally publish this story for posterity.

A Technology Leap for PowerBuilder Developers

Thu, 24 Jul 2008 14:00:00 EDT

Sybase has just released the latest version of its premier .NET development tool in PowerBuilder version 11.2. I am proud to say that I haven't missed a beta since November 1989 (version 0.8) and that includes PocketBuilder and InfoMaker too. I need to thank the people at Sybase for continuing to let me test drive their new code.

PBDJ Blogger Chris Pollach Reaches 150,000 Reader Mark

Tue, 11 Dec 2007 10:15:00 EST

I just wanted to acknowledge the tremendous increase in the amount of Blog activity that I have received over the past year. I think (and hope) that this is because many Sybase professionals out there have come to visit my site for latest information on the Sybase scene. Since I started my Blog in August of 2005 I have seen a steady increase in unique visits to my site. This whole Blog experience of course is Reed Shilt's fault. Reed is the development manager for PocketBuilder and started the whole thing off by opening his own Blog within PBDJ, then sending me an invitation to join him in this new venue. At that point in time, Blogging was a whole new experience for me and in fact, I had not even heard the term until I received Reed's email.

Dynamic SQL with Sybase's Open Client

Fri, 11 Aug 2006 10:45:00 EDT

PowerBuilder offers some dynamic querying capabilities. For simple scenarios it works quite well. But what if your scenario isn't simple? What if you wanted to write a database-querying tool that provides stored procedure compilation, ShowPlan display, or the execution of large complicated batch scripts?

PowerBuilder - The ClassDefinition Object

Fri, 19 May 2006 11:15:00 EDT

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.

Integrate Real-Time GPS Data Into Your PowerBuilder Applications

Sun, 19 Feb 2006 12:30:00 EST

We begin this article by asking the question: Why would you want to integrate real-time GPS data into your PowerBuilder applications anyway? After all, it's not likely you are going to connect a GPS receiver to your desktop computer and ask yourself where you are currently located. (At least I hope not!)

Custom Common Dialogs Using SetWindowsHookEx

Tue, 26 Apr 2005 10:00:00 EDT

PowerBuilder contains a number of built-in common dialogs that can be used within your own applications. What do you do when one of these dialogs meets most, but not quite all, of the functionality you need? Do you simply accept the limited functionality? Do you write your own dialog from scratch to replicate them and add the additional functionality (a maintenance headache)? There is a third option. You can simply use the dialog that PowerBuilder provides and modify it at runtime to provide just the additional functionality that you need. The dialogs PowerBuilder provides include: The GetFileOpenName, GetFileSaveName, ChooseColor, GetFolder, PrintSetup, and PrintSetupPrinter system function dialogs The DataWindow Control SaveAs, SetFilter, and SetSort function dialogs The DataWindow object DataWindow.Print.Prompt attribute dialog The ubiquitous MessageBox dialog. For the purposes of this article we're going to use the DataWindow control SaveAs dialog, but the technique can be used to customize any common dialog.

SQL Anywhere Studio 9 Developer's Guide

Sat, 02 Apr 2005 11:00:00 EST

As a PowerBuilder developer I'm sure you have already used SQL Anywhere a few times, but did you know that SQL Anywhere owns over 70% of the mobile database market? This is because it's easy to use, easy to administer, and doesn't take up too much space.

Working with the Enterprise Portal

Fixing Ugly Grid Borders

'Bag O' Tricks'

Thu, 11 Sep 2003 16:00:00 EDT

With Halloween just around the corner, I thought I'd give you some of the 'tricks and treats' that I've collected over the years for PowerBuilder, InfoMaker, and Sybase ASE.

Refactoring Techniques in PB

Thu, 11 Sep 2003 16:00:00 EDT

In early versions of PowerBuilder, development primarily consisted of three types: composing graphic objects by adding visual controls; coding functions and events using PowerBuilder's native language, PowerScript; and creating DataWindow objects.

Fri, 08 Aug 2003 09:00:00 EDT

In this article I'll show you how to play MP3 files with your own 'sound machine' written in PowerBuilder. But before we start to implement it, you should first understand what MP3 is.

'Rubbin' Sticks Reporting (RSR)'

Mon, 21 Jul 2003 11:00:00 EDT

Myth: 'Creating reports with InfoMaker is easy,' a partially accurate statement, on the surface. Reality: Let's change that to: 'Formatting your report with the InfoMaker tool is easy, once you've figured out the data to be reported.'

Boosting Performance on DataWindow Retrieval in n-Tier Environments

Thu, 01 May 2003 00:00:00 EDT

When I started using distributed DataWindows, the slow performance frightened me, usually when the middle server and the client were in separate computers. At that time I was using a PIII 500 desktop computer, and a PIII 800 database server over a 10MB network. Although it's not the top-of-the-line hardware environment, it's still the best some customers can get.

'The tag property takes a string value.' That's what PB Help tells us about the tag property. Not much considering all or at least most PB objects have a 'tag' property. What's its mission in life? Anything we want it to be.

DDDW Tips and Tricks

Sat, 01 Feb 2003 00:00:00 EST

The DropDownDataWindow (DDDW) edit style is one of PowerBuilder's outstanding features. Yes, I know there are a lot of new and exciting capabilities in the upcoming release of PowerBuilder, but in this article I'll try to solve some of the current problems with the existing features that are popping up in nearly every project I've seen.

Wallpaper Setter in PowerBuilder

Sat, 01 Feb 2003 00:00:00 EST

My son is only 18-months old but I have taken more pictures of him than I can count. Thanks to digital cameras it's so easy to take and store pictures. Since I spend most of my time on the computer, I formed the habit of changing the Windows desktop with his latest portrait both at work and at home. However, the initial excitement faded due to my inherent laziness.

Dynamic Report Module Basics

Using Interfaces with PowerBuilder

Fri, 01 Nov 2002 00:00:00 EST

Interfaces are one of the most important concepts that have found their way into modern software engineering in the past couple of years. Java, COM, CORBA, C# - all those languages/concepts support interfaces. PowerBuilder does not. This article shows you how to sneak the interface concept into PB by using some of its special features.

Eight Reasons to Upgrade to PowerBuilder 8

Thu, 01 Aug 2002 00:00:00 EDT

If you're using PowerBuilder 6 or 7 for new development, you should really be using PB 8. It's the fastest way to build a new client/server application or move PowerBuilder business logic to a distributed n-tier environment.

Incorporating Popup and Lookup Windows into JSP HTML DataWindows

Thu, 01 Aug 2002 00:00:00 EDT

When moving applications to the Web, one of the challenges facing developers is how to migrate rich client features to a browser environment. Two features that can give your Web applications a boost in both appearance and functionality are popup calendars and lookup (search) windows.

Web DataWindow Containers and Service Classes

Wed, 01 May 2002 00:00:00 EDT

New to PowerBuilder 8.0 is the ability to deploy your DataWindows to a Web server as self-contained components. These new components are called Web DataWindow Containers. These containers will convert your collection of DataWindows into HTML with the aid of your Component Transaction Monitor (EAServer or an equivalent server).

Introduction to the Bulk Copy Program

Thu, 01 Nov 2001 00:00:00 EST

If asked to name tasks that get in the way of the creativity and enjoyment of application development, developers of any language would produce a similar shortlist. Testing, documentation, source control management, and tracking project time are but a few. PowerBuilder developers have their own tribulations.

A Snippet Here, a Snippet There

Thu, 01 Nov 2001 00:00:00 EST

Once upon a time there was a source code editor called 'Brief.' Okay, so it was DOS-based and had an ugly interface. However, it had one feature I truly loved, a 'code snippet' manager. You could have your favorite block of code inserted into your source with a few keystrokes. Eventually, I stopped writing Clipper code and started using PowerBuilder, which didn't have this built-in feature...until now.

Communicating with EJBs from PowerBuilder Using COM/DCOM

Mon, 01 Oct 2001 00:00:00 EDT

It would be better to live in a world of best-case scenarios, where all parts of the enterprise puzzle are provided by the same vendor. But that's the exception rather than the rule. It's often the case in the modern enterprise that companies will standardize on technologies from a wide variety of vendors and platforms. As programmers we often don't get as much input into those decisions as we want. We end up having to develop in a tool provided by one vendor, with access code running in an application server provided by another, using a communication protocol developed by yet a third.

PowerBuilder has been around for 10 years, and has grown exponentially in that time. Now, in 2001, PowerBuilder has matured to a new level - version 8 There were a lot of 'firsts' with PowerBuilder, and now it has become the unquestioned development productivity tool for the enterprise.

PowerBuilder 8/4GL Web

Wed, 01 Aug 2001 00:00:00 EDT

My last article (PBDJ, Vol. 8, issue 6), which introduced PowerBuilder 8 and Web targets, demonstrated how to create Web pages from within the PB development environment. This article reviews the 4GL Web server-side event model and discusses how it helps reduce development time and effort. Using this event model allows developers to concentrate on business logic and interface design rather than the low-level details of accessing EAServer components.

I realize that many people are talking about nothing but Java, and yes, I'm writing Java components myself; however, PowerBuilder still lives on. There are many existing PowerBuilder client/server applications in production that need to be maintained and many that need to be moved to the Web. PowerBuilder 8 has some nice development features that make it an environment for PowerBuilder applications as well as Web applications. This article discusses the new user interface and concentrates on Web targets.
