Remember however, that you can run a visual class in a private datasession.

* Session.PRG
DEFINE SessionBase AS Session 
   PROCEDURE Create(Class, ClassLib)
      RETURN NEWOBJECT(m.Class, m.ClassLib)
   ENDPROC
ENDDEFINE

Write code like this:

oSession = NEWOBJECT("SessionBase","Session.PRG")
oMyVisualObject = oSession.Create("MyVisualClass", "MyClassLib")

>>>Is it true that I cannot use the Visual Class Designer to create a class based on the Session class?
>>
>>Yes, the Session class can only be subclassed in code.
