Inheritance is achieved by using “Inherits” keyword in VB.NET (For C# it is “:”). Simple

Sample is provided in CD for understanding inheritance in folder

“WindowsApplicationInheritance”. There are two classes one is the parent “ClsParent”

and second is the child “ClsChild”. Parent class has a string which has to parsed for junk

data “@” and “/”.ClsParent has the functionality which parses only cleans up

“@”.”ClsChild” then inherits from parent and adds extra functionality by parsing “/”.

Public Class ClsParent

Protected strData As String = “jksdhkj@dadad///ajkdhsjakd”

Public Function Parse() As String

Dim PstrData As String

PstrData = strData

PstrData = Replace(PstrData, “@”, “”)

Return PstrData

End Function

Public Function GetActualString() As String

Return strData

End Function

End Class

Above is the source which parses only “@” of strData variable.

Public Class ClsChild

Inherits ClsParent

‘ this is child and a special parse function is added which will

also parse “/”

Public Function ParseBackSlash()

Dim PstrData As String

PstrData = Me.Parse()

PstrData = Replace(PstrData, “/”, “”)

Return PstrData

End Function

End Class

Above is the source code for “ClsChild” which does the remaining work. It adds extra

functionality by parsing “/” junk character’s of the data.
