COM: How to retrieve CLSID? Can Prog-Id be used?

Question

Hi,

if I have a known COM library (the .ocx file itself) is there any way in C# to extract the CLSID info of it? Basically I need the same infos from the file Visual Studio adds to its project file when you add a reference to the file. Can these be retrieved from the ocx file directly or by searching the registry?

Also if i know a prog-id, how can I find the CLSID and the corresponding ocx file?

Thanks for your helping out a COM novice!
