Oracle was slow to introduce support for returning result sets from stored procedures. When they finally did add such support, they did so in a manner that was somewhat different than the approach used by other vendors. This has a couple of consequences for PowerBuilder developers. The first is that the PBDBMS approach was developed within PowerBuilder as an interim workaround. The second is that using stored procedures to return result sets is not as widespread a practice with Oracle databases as it is with other database products. This article (an excerpt from an upcoming book on PowerBuilder 9) is an attempt to address this situation. The interim PBDBMS solution is going away. In PowerBuilder 8, support for the PBDBMS was restricted to the O73 driver and with PowerBuilder 9, support for it will be dropped completely. If you're still using that old technique and n...

DataWindow.NET Pet Shop

In the early days of Java, a sample application called Java Pet Store was introduced as a "blueprint and guideline" for Java development. A few years later when Microsoft introduced .NET, they also provided a similar sample application to demonstrate preferred methods of coding for .NET called .NET Pet Shop. That has subsequently resulted in a bit of warfare as the two camps attempted to demonstrate why their implementation was a better, higher-performance implementation. To provide a sample of using DataWindow.NET, I took a look at the .NET Pet Shop with an eye toward demonstra... (more)

The Next Paradigm Shift...

First there were the thin clients. Not the Internet thin clients, I'm talking about the mainframe applications with dumb terminals. Everything ran on the server; the client was basically there only to display and for input from the user. Then PCs came along and a paradigm shift occurred toward thick clients. Really thick clients in fact. Not only was the user interface running locally on the PC, but often so was the data access layer, with the application accessing local database files or perhaps a shared database file on the network. Key reasons for the shift were a better user... (more)

What's Coming in the Next Version of PowerBuilder?

Last month my editorial was about "must-have" improvements in PowerBuilder. Well, shortly after that piece was written we got a sneak peak at the enhancements coming in the next version of PowerBuilder. I can't say I got everything on my list, but some of the coming attractions are quite interesting. Strangely enough, the peak came as a result of an ISUG tech cast on the "compile to ASP.NET" feature that's supposed to be one of the major features of PowerBuilder 11. That feature is dependent on ASP.NET 2.0, and Microsoft recently announced a six-month slip in the ASP.NET 2.0 rele... (more)

DataWindow.NET How To: DataWindow Formatting

In this article, we're going to look at how DataWindow.NET technology is a simpler but more powerful way of formatting data in the presentation layer. We'll be taking a sample application provided by Microsoft for .NET and implementing it using DataWindow.NET technology. In this case, we're using the Visual Basic .NET Code Sample: DataGrid Formatting sample application available at www.microsoft.com/downloads/details.aspx? FamilyID=28fd458f-5571-42b4-a2fe-09b69ddf0863&displaylang=en. The original sample was written to connect to the Microsoft Northwind sample database. So you'll ... (more)
