Creating and Using Controls

A control is an object that can be drawn on a Form object to enable or enhance user interaction with an application. Controls have properties that define aspects their appearance, such as position, size and colour, and aspects of their behavior, such as their response to the user input. They can respond to events initiated by the user or set off by thesystem. For instance, a code could be written in a CommandButton control’s click event procedure that would load a file or display a result.

In addition to properties and events, methods can also be used to manipulate controls from code. For instance, the move method can be used with some controls to change their location and size.

Most of the controls provide choices to users that can be in the form of OptionButton or CheckBox controls, ListBox entries or ScrollBars to select a value. Let us discuss these controls by means of a few simple applications in the following lessons.
