About Me

Me is a reserved name (you can't have a variable by that name) that refers to something that can only exist at run-time in a procedure's scope: the current object. Under the hood, when you make a member call to DoSomething against a Class1 object, the call goes essentially like this:

Set obj = New Class1
Class1.DoSomething obj

This means DoSomething looks like this in VBA:

Public Sub DoSomething()
End Sub

But VBA sees it like this:

Public Sub DoSomething(ByVal Me As Class1)
End Sub

That makes Me an implicit locally-scoped ByVal parameter of type Class1, and inside the DoSomething scope it holds a reference to whatever object the caller is currently using.
