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.

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)
