Collections are a common way to store multiple instances of things.For example, a TreeView control has a Nodes collection and Microsoft Word has a Documents collection. Until recently, Visual FoxPro developers wanting to use collections often created their own classes that were nothing more than fancy wrappers for arrays. However, in addition to being a lot of code to write, home-built collections don't support the FOR EACH syntax, which is especially awkward when they'r...See More

Visual FoxPro developers have been using an event-based methodology for a very long time.For most purposes, events are what drive the development effort. The user clicks a button, causing an event to fire, and the developer writes code to react accordingly. All of this happens very transparently and without difficulty for either party. However, from a developer's point of view, there also isn't much flexibility in this approach. But in VFP 8, event handling is changing for the better.

Visual FoxPro 8.0 introduces a whole new way to work with eXtensible Markup Language (XML).The XMLAdapter class works with hierarchical XML, provides an object-oriented approach to working with XML data, and leverages your familiarity with tables and fields in the way it exposes the XML contents.
