Something like (not tested, off my melon):

lcControl = _screen.activeform.activecontrol.name
loControl = _screen.activeform.activecontrol
do while not compobj(loControl, _screen.activeform)
    loControl = loControl.Parent
    lcControl = loCOntrol.Name + '.' + lcControl
enddo
?lcControl

You can replace the form name with _screen.activeform if you want, but I don't see how good it is, you still have an object reference.
