Question

I've got this code:

  Public Class Events

        Inherits MyModule
        Private myTag As MyPoint
        'Call Calculations() here!


        Public Overrides Sub Calculations()
         'Do stuff with myTag
        End Sub
    End Class

As commented, I need to call Calculations() from class Events. I tried Dim mycalc As New Calculations() but I get

Type 'Calculations' is not defined.

Answer 1

When you do this:

Dim mycalc As New Calculations()

You're not trying to call the Calculations method. You're trying to instantiate the Calculations class . It's not a class, hence the error.

You need to create an instance of the class and then call the method on that instance. Something like this:

Dim myEvents As New Events()
myEvents.Calculations()

Conversely, if you're trying to call the method from within the Events class, you can just call it directly (since the current class instance is already defined):

Calculations()
