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)

User Group Malaise?

Read an interesting article about the .NET Developer Association user group in Redmond, Washington. You would think that the user group in Microsoft's backyard (the meetings are held at Microsoft's offices) wouldn't have any problems lining up guest speakers and drawing a crowd. Well, it looks like they do because they've had to cancel several recent meetings and have proposed taking a six-month break to try to determine how to revitalize the group.[1] It had me wondering why such a group would have difficulty holding meetings. Of course, the issue may be specific to that partic... (more)

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)

Calling .NET Components from PowerBuilder

I've written a number of articles in the past on using .NET components, both visual and non-visual, from a PowerBuilder "Classic" (i.e., Win32) application. Until now, all of them involved using a .NET component that was either provided in the .NET Framework or created using Visual Studio. What changes with PowerBuilder 12 is that we can now write a non-visual component using PowerBuilder.NET, so the solution is entirely PowerBuilder based. Technically, this really first became possible with the introduction of the .NET assembly target in PowerBuilder 11. However, there were a cou... (more)

Say Hello to PowerBuilder 12.5!

By the time you read this, PowerBuilder 12.5 should be released. Like several ".5" releases before it (i.e., 6.5, 10.5 and 11.5), this release is a major release with a number of significant new features. We'll have a number of individual articles in PBDJ that will dive into these new features in greater detail. Given the editorial lead time, I wouldn't be surprised if you've even read a few by the time you read this! For now though, I'd like to give a brief overview of what you'll see in this new version. PowerBuilder Classic Just to show that you haven't been ignored if you're s... (more)
