What is a property? What is an event?
Property - A property is a thing that describes the features of an object.
A property is a piece of data contained within a class that has an exposed interface
for reading/writing. Looking at this definition, we might think we could declare a
public variable in a class and call it a property. While this assumption is somewhat valid,
the real technical term for a public variable in a class is a field. The main difference
between a field and a property is in the inclusion of an interface.
We make use of Get and Set keywords while working with
properties. We prefix the variables used within this code block with an underscore.
Value is a keyword, that holds the value which is being retrieved or set.ss="a">
Private _Color As String
Public Property Color()
_Color = Value
Event - An action that an object does. When something happens, we say
an event has happened. For example, when a button is clicked, we say it is
the click( ) event. When a mouse hovers on an image, we say the mouseover( )
event has taken place.
