Inside More Controls
This chapter examines more Compact Framework controls, and other elements which are useful

events in the standard Compact Framework controls.

Detecting Support for Properties, Methods, and Events
Visual Studio .NET provides many features which help programmers create, debug, and
deploy Compact Framework programs. Woven into those features is knowledge of many aspects
of programming: syntax checking helps tag errors even before you build, automatic code
generation provides a starting point for your code, and IntelliSense shows available namespaces,
classes, and other type information to simplify your code development.
