How to list all ActiveX controls?

Question

Is there a way to view / view all ActiveX controls in the system or for a specific application? Can this be done on any administration screen, as well as in code?

Thanks for any help.

Answer 1

I usually use OLEview to check COM / ActiveX objects on my computer, as this also allows me to check the interfaces exposed by objects.
