Does anyone have an example?

Thanks,

as far as I know, it's not possible on Firefox.
Ocx and activeX elements work only with IE, and nothing else.

OCX was a way of storing executable code from the VB 4 days. It's a proprietary Microsoft technology, folded up under ActiveX. I've never tried in FireFox, but I wouldn't be the least bit surprised if it were IE only, as Tripy said. Listen to the ducky.
