Sub in child class

[Vmrincon]

Hi!

I have a small problem...

I have a base class that has several constructors but all of them
have some parameters. It looks something like that...

Class 1

'Some properties

Sub New (Param1 as Type1)
Sub New (Param2 as Type2)
Sub New (Param3 as Type3)
Sub New (Param4 as Type4)

Now I want to declare a new clase that inherits from this one. The
reason for this class is to add some extra properties that the parent
class doesn´t need to have, so I will do something like this...

Class2 inherits Class1

'Extra properties

But now .NET ask me to declare a Sub New because the parent class
doesn´t have any constructor without parameters.... I wonder how can I
do that??? Could anyone help me????

Thank you!!!

VB.NET doesn't not inherit the contstructors - you need to retype all the
parameterized constructors.

i.e.:

Sub New(ByVal Parameter as string)
MyBase.New(Parameter)
End Sub

i.e.:

Sub New(ByVal Parameter as string)
MyBase.New(Parameter)
End Sub

Also, be aware that if you put in a constructor with parameters, the
default constructor (for no params) is no longer created by .net, and you
have to include one if you want one.
