14.1.1..Introduction..........................................................................................

There are two particularly important pieces of information about every control of your

application. The information stored in the control and the action or type of action the user

can perform on that control. At its most basic level, at one time in the life of an

application, a control holds a value that can be of particular interest either to you or to the

user. On the other hand, when interacting with the computer, based on your application,

the user will usually face different types of controls that do various things and produce

different results. These are two features of controls (their values and the actions the user

can perform on them) that you should know as much as possible, about the controls you

choose to involve in your application.
