You're getting Object.AddObject and CREATEOBJECT mixed up. The AddObject method does not return an object reference like CREATEOBJECT does, and it it not a function, it is a method of an existing object. So after using AddObject, you just refer to the object through it's container hierarchy:

THISFORM.PageFrame1.Page1.Addobject('field1','kbafield')
THISFORM.PageFrame1.Page1.Field1.top=100

AddObject uses your SET CLASSLIB setting to search vcxs it knows about.
