How do I get a list of all COM automation servers?

Question

I'm trying to call various APIs that are exposed as COM from Silverlight, which is possible only when they are part of a registered automation server and have a respective progid. Word, for example, would be "Word.Application". How do I get a list of all registered servers with their respective progids?

I found the component services snap-in, but I can't find the progids I know about in there. Edit: The snap-in looks like it should be there, I found a properties window that shows applications ids for some COM+ and DCOM applications, but I can't find obvious servers such as Word. The COM+ tree contains only half a dozen entries.

Answer 1

The list of automation servers appears to be in the registry under HKEY_CLASSES_ROOT. From Silverlight, the name of the key is the progid, the CLDID is the value of subkey called CLSID.

I found this after Hans Passant made a comment to my question mentioning the registry.

Answer 2

PrimalScript, by Sapien Technologies Inc., has an object browser that does an excellent job of listing all of the usable COM objects/interfaces on the system.
