Inherit a class with a private "New()" sub?

Please forgive me if this is a dumb question but...

I am learing how to extend a class with some properties and methods of my own design. When I create the class code and add the Inherit statement I get this error:

Class 'PourLine' must declare a 'Sub New' because its base class 'LineClass' does not have an accessible 'Sub New' that can be called with no arguments.

When I attempt to add a sub called "New" I get this error:

First statement of this 'Sub New' must be a call to 'MyBase.New' or 'MyClass.New' because base class 'DesignCAD.LineClass' of 'Exploring_Capping_Classes.PourLine' does not have an accessible 'Sub New' that can be called with no arguments.

When I try MyBase.New() the error is:

'DesignCAD.LineClass.Private Sub New()' is not accessible in this context because it is 'Private'.

Is there any way I can create a class that inherits the methods and properties of the base class?

My simple code:

Public Class PourLine
Inherits DesignCAD.LineClass

Sub Build()
MyBase.New()
End Sub
End Class

Thanks in advance for your help.

Why not make the New in the inherited class protected?

Like This?

Public Class PourLine
Inherits DesignCAD.LineClass

Protected Sub New()
MyBase.New()


End Sub
End Class


When I do I still get the same error which is:

'DesignCAD.LineClass.Private Sub New()' is not accessible in this context because it is 'Private'.

Thanks,
Eric

No. The class you are inheriting. Assuming you have access to the code to do that. Otherwise, it wasnt designed with being inherited in mind.
