Component (DLL) Question

[Tec-Nico]

Hello, I was asked for a class to develop a component.

What this component has to have is an interfase and its contract.

So I began with an ActiveX DLL project... How would I develop the interface? Or am I doing the wrong thing? In our classes we were told Components didn't behave like Objects but I have this:

Option Explicit
 
Private Sub Form_Load()
 Dim myComponent As VBToExcel
 Set myComponent = New VBToExcel
 
 myComponent.DoSomething
 
 Set myComponent = Nothing
End Sub

What am I missing? Did I mess it up? I mean, the code is working but it shouldn't be done like that, should it?
