PowerBuilder 11 introduces the WebForms target, which lets you transform an
existing PowerBuilder application into a Web application with relative ease.
While the deployed application will be remarkably faithful to the original
client/server deployment in terms of application behavior, the degree of
faithfulness is limited by the fact that your application is running as a Web
application. The PowerBuilder component where this poses the greatest
challenge is the DataWindow.
The aim of this article is to point out where the transformed application
will differ in terms of latency, performance, and look and feel and what you
can do to minimize these differences.
Other than the fact that the WebForms DataWindow runs in the browser, another
source of differences in behavior with respect to the traditional
client/server DataWindow is the fact that the underl... (more)
While there is literature describing how to use .NET controls in PB (see for
example, past issues of this magazine), all are silent on how to set control
properties at runtime and how to persist them. This article will address both
Like regular OLE controls, you can allow your .NET control properties to be
set at design-time by means of property pages (see Figure 1).

With all the attention in PB12 focused on .NET and WPF, some of you may be
wondering about the future of Win32 targets in what is now being called PB
Classic. Those hoping to still continue to work with Win32 targets in PB
Classic can rest assured, PB Classic is not going away and we are backing
that statement up with the features we are going to introduce in PB12.5.
Controls in DataWindow and Outside Converging in Capabilities
In this major release you are going to find two long-asked-for features

By the time you are reading this, PB12.5 will have been released and work on
PB15 well under way. A lot of exciting things have gone into the .NET version
of PB but we still get requests for features to go into the Classic version
of the product. Even though there was a lull in activity in PB12 Classic, we
are back again in 12.5 - and we are not stopping. You will probably have seen
Dave Fish's webcasts on plans for PB15 (his disclaimers apply here as well)
and are hungry for details - I hope to address that in this article.
PB has been around a long time and has accumulated many ... (more)
In PowerBuilder 11.5 we introduce features that allow you to easily give your
existing DataWindows a new look and feel. New properties are added to columns
and controls to allow you to add tooltips. You no longer have to settle for
single-colored backgrounds. We have introduced properties to control color
gradients and translucency for the background of columns, and most controls
and bands. For the DataWindow background, in addition to color gradients, you
can use bitmaps as wallpaper, giving you control over how the image is tiled.
Since these new properties are DataWindow prope... (more)
