The CODE Framework is an open-source application framework by the makers of CODE Magazine. It is entirely free of charge. It covers a wide range of features that can be applied altogether or individually in an À la carte fashion. All of these features revolve around a single concept: Building advanced business applications in a productive and maintainable fashion while maintaining great application architecture. In this article, we are focusing on a subset of the CODE Framework, specifically the components used to build WPF applications using the MVVM and MVC patterns.

How to manage the Dialog boxes in WPF application

Bill Kratochvil delves deep into the history of design patterns as he presents the advantages of developing extensible enterprise apps with what he calls the MVPVM pattern, inspired by the Microsoft patterns & practices Prism project.

Most programmers have a hard time making applications that look interesting and fun. We are great at creating functionality that makes the application do exactly what the user wants, but many applications often look very utilitarian. However, with just a few little XAML tricks, you can make your Silverlight or WPF applications look like an artist had a hand in their creation. In this article I will provide you with a couple of very easy XAML tips that you can use right away to spice up the images in your Silverlight and WPF applications.

In a previous PBDJ article, we looked at using a third-party control, a ribbon control in particular, in a PowerBuilder WPF target. One of the other “most requested” features people have asked for is the capability to provide docking windows in their PowerBuilder applications. In this article, we’re going to look at how we can do that in a PowerBuilder WPF application using a third-party docking manager. The particular docking manager I’m going to use is the AvalonDock, an open source project on CodePlex (http://avalondock.codeplex.com/). At the time of this writing, the current version is 1.3.3571. However, that one has some dependencies on Visual Studio 2010 and .NET Framework 4.0 libraries. PowerBuilder .NET 12 is based on the Visual Studio 2008 isolated shell, so I’m using an older build (1.1.1509) that doesn’t have these dependencies. First, we’ll add the AvalonDock assembly and a reference to a new WPF application. Create a new WPF window and add the AvalonDock namespace to the Usings property for the new window. I called that new window w_frame, and coded the open event of the application object to open it. I then dropped a DockingManager control onto the window. Next create a menu (I called mine m_menu) and associate that menu with the new window as well.
