>Not sure about any of this. In VFP I went into Tools/Options/Controls and this control was in the ActiveX list. So I checked its box, saved the options and it now appears on the ActiveX toolbar but doesn't work. I assumed since it was in the list that it was installed as part of VS6. Is this not the case?

No. Having the OCX on your system and being able to use it for development are two very different animals. The OCX was installed by some software product (I don't think it was VS6) to use it. You need different registry entries in order to enable it for development. You'll probably have to purchase your own copy in order to get those registry entries.
