I used it only once :). I took the parameters from what the object browser showed me... like this:

ospell=GETINTERFACE(this.object.SpellCtrl, "{8A8763C7-D866-4D33-A6E9-FF17C008D57B}", "WPTDynInt.ocx")

This was called from the .init of my olecontrol, and SpellCtrl was one interface of the control which wasn't exposed. Don't remember where I got the GUID - from the object browser or from the author, or did I dig it from the registry (unlikely :).
