Comentários
When a variable is defined using WithEvents, you can declaratively specify that a method handles the variable's events using the Handles keyword.
You can use WithEvents only at class or module level. This means the declaration context for a WithEvents variable must be a class or module and cannot be a source file, namespace, structure, or procedure.
You cannot use WithEvents on a structure member.
You can declare only individual variables—not arrays—with WithEvents.
