>Can you create a visual class with this object added and instantiate that class in your code?

I tried

LOCAL upt as UPT.UptCtrl.1 OF upt.ocx
* Next line causes error Object class is invalid for this container.
upt = CREATEOBJECT('upt')
upt.AboutBox()
RETURN

DEFINE class upt as olecontrol
    OleClass = 'UPT.UptCtrl.1'      
ENDDEFINE 

but got exception in createobject as shown in comment
