if I do that, I get "'New' cannot be used on an interface".

oops, sorry.  The new should be used on a class that is based on the interface

dim obj as InterfaceX = new classX

with the following:
Public Interface InterfaceX
    Sub IFoo()
End Interface

Public Class classX
    Implements InterfaceX

    Public Sub IFoo() Implements InterfaceX.IFoo
        MessageBox.Show("Foo")
    End Sub
End Class

Hi HLRosenberger;

An interface is a definition of what needs to be implemented in your code to fulfill the contract of that interface. Please see this Microsoft Documentation on Interfaces (Visual Basic) for more details.
