Gary,
This object does not have a containership parent because of the way you created it, therefore it can not use this.parent or thisform.
If you changed your code to:
Thisform.AddObject('oMyClass', 'MyClassName')
The object would be contained within the form and have a this.parent and can also use thisform.

>Without passing a reference to the class of Thisform, is there anyway in the class to access ThisForm ? If in the object, I refer to THIS.PARENT, it does not get me a reference to the containing form.
