PowerBuilder 12.5 introduced a number of significant enhancements to web services support, both for creation and consumption. In particular, the following were introduced as new features in PowerBuilder.NET: WCF client proxy WCF service target REST client proxy We're going to look at what those new features provide and how to use them. We're also going to look at how we can package some of that functionality so that it can be used from PowerBuilder Classic applications as well. Windows Communication Foundation (WCF) First though, some background. When support for a web service client was first introduced in PowerBuilder 9, it was done based on an open source library called EasySOAP. There were some limitations with that implementation, primarily because the EasySOAP library only supported SOAP 1.1, was limited to XML over HTTP transport, and provided no support for an... (more)

Perhaps I Haven’t Made Myself Clear...

I've been discussing HTML5 for some time now. In July of 2010, I mentioned that I wasn't particularly concerned about PowerBuilder supporting HTML5 in the initial PowerBuilder.NET release (12.5) because: "HTML5 is largely still in its infancy, and there appears to be too much opportunity for it to fragment as previous HTML standards have done." [1] In December of 2010 I devoted an entire editorial to HTML5 [2], noting that: "I have some basic concerns that make me reluctant to recommend using HTML5 as the basis for any line of business application development in the near future." ...

Silverlight Is Dead, Long Live Silverlight

There's been a lot of discussion since Microsoft's BUILD conference on the fate of Silverlight. (Something that is an issue for us because Sybase was originally looking at supporting it for web app development in PowerBuilder 15.) Contrary to what a number of the pundits and would-be pundits have said, I don't think it's quite accurate to say that Silverlight is dead in Windows 8. I think it's more accurate to say it's evolved. As background for those who haven't been following this closely, Microsoft announced that the Windows 8 operating system would support two kinds of appli... (more)

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)

DataWindow.NET How To: Data Entry Form

Last month we looked at Microsoft's .NET Pet Shop sample application and saw how DataWindow.NET technology could be used in the data access layer of an ASP.NET-based application to reduce the its complexity and increase developer productivity. This month we'll look at another Microsoft sample application to see what benefits DataWindow.NET technology can provide when used for data presentation and data access in a Windows Forms (WinForms) application. To fully appreciate how much DataWindow.NET simplifies the development of database applications in Windows Forms, you'll need the ... (more)
