Hi!

You cannot add such kind of objects to the form using usual VFP objects containership tree rules. COM object is not a native VFP object (or VFP object wrapper for ActiveX). You cannot create visual class in VFP that become ActiveX insertable to VFP form as usual ActiveX (in VF you can create visual ActiveX).

If you just try to use non-visual COM object, instead of AddObject() use following:

thisform.addProperty('loCir',createobject('circuitos.circuito'))

HTH.
