>I need to write a routine to determine if a given activeX control is registered on the workstation. I am looking at the FFC--VCX: Registry; Class: Registry; Method: IsKey. I think this is the right place to start. I found the documentation on the VCX but I still have a few questions:
>
>1. Is "IsKey" the right method to use for determining whether a given activeX control is registered?
>
>2. If so, what values should the developer specify for cKeyName and nRegKey? Would cKeyName be the name of the OCX?
>
>After I get this working, the next step will be to register the OCX if it is not already registered, assuming the OCX file can be found.
