Objects
Effective Visual Basic 6 programming is based on
the concept of objects. An object is a distinct unit
in a program that has certain properties and can perform
certains actions.
An object is a special type of variable that stores
data and manipulates that data by passing messages
to itself. |
|
Properties are data that describe an object. |
Following are the characteristic that all objects
have in common:
- Each object is a self contained unit. The existence
of one particular object is not dependent on the
existence of another.
- Although individual objects are unique, each
object can be identified as belonging to a particular
classification through properties.
- Objects respond to certain predefined events.
- Object can interact with each other and with
the outside world in a prededined manner.
- Although each object behaves in a different
way, many of the things objects know how to do
can be given the same name.
