You'd have to iterate through the HKEY_CLASSES_ROOT hive of the registry and check the information on every CLSID to see if it offered an ActiveX control service; this is more than simply offering an in-proc server, since not all in-proc servers are ActiveX controls. If I'm not on a development system, then I'm concerned with the existence of specific controls, and I check for the presense of the ProgID or CLSID of interest in the HKEY_CLASSES_ROOT hive.

There are other tools than the Component Gallery; OLEView.EXE also knows about controls and interfaces, as does the VB Object Browser.
