Objects, Properties and Methods
Objects consist of code and data that work together as a
unit. Data is stored in an object in the form of Properties.
Properties are attributes or characteristics that control an objects appearance
or behavior. BackColor, ForeColor, Width, Font, and Text are all Properties of
an object. You can think of a Property as an adjective that describes an object
Objects also contain code in the form of Methods.
Methods are procedures that contain instructions that the control can execute.
You can think of Methods as actions that an object is capable of performing.
A textbox is capable of clearing the contents of its Text
property or capturing the Focus of the form by using the Clear
and Focus methods.
A Form is capable of removing itself from memory by using
it's Close method.
To reference any member, Property or Method of an object we
use the dot operator. The statement
txtName.Clear
will cause the contents of the object txtName to erase the
contents of it's Text property.
To set focus to an object in code we can
txtName.Focus
To close a form we
Me.Close
NOTE: When referring to a Form within that Form's class
module (in other words when a Form refers to itself) we must use the Me
operand.
