This is the second part of an ongoing series about the new features that were added in PowerBuilder 11.5. In the first part, we looked at the Federal Desktop Core Configuration (FDCC) and the impact it had on developers. In this part, we're going to look at a number of the improvements in GUI functionality. We'll start that by comparing a couple of screenshots of images in DataWindows (Figure 1 and Figure 2) that demonstrate a number of these new functions. Support for PNG Files The first thing you may notice is that the image type (in both images) is a Portable Network Graphics (PNG) file. The PNG file format was introduced to overcome limitations of the GIF file format, most notably: The compression algorithm used in GIF files is patented. GIF images are limited to a 256 color depth PNG images actually provide greater compression than GIF and provide better suppor... (more)

Using Oracle Stored Procedures in Your DataWindows

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.

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)
