VFW020 – Execute a Visual LANSA Framework Application

What is the Visual LANSA Framework (VL Framework)?

The VL Framework is an optional extension to Visual LANSA which provides an application Framework for designers and developers.

For the end user, the VL Framework provides consistent and well designed interface with many standard features which provide a powerful and flexible user interface. It is loosely based on Microsoft's Outlook  interface design, which will be familiar to many end users.

For the designer, the VL Framework provides a rapid prototyping tool. The prototype will be developed into a real application.

For the developer, the VL Framework provides the tools to rapidly build a sophisticated modern application for Windows or Web deployment. It is especially beneficial if the developer is new to Windows or Web development. However, the power and flexibility of the Framework lends itself to most business applications and should be considered for all your LANSA projects.

VL Framework applications can be developed as Windows Rich clients, Web Browser based applications and Microsoft .Net applications.

If you are new to the VL Framework, you should study the Visual LANSA Framework Guide, the tutorials that it contains and the extensive shipped demonstration applications, which include all source code with extensive comments to enable their re-use.

These exercises provide an introduction to developing VL Framework applications for Windows, but time constraints mean that there is much more to learn in order to fully exploit the power and flexibility of VL Framework.
