Urgent!! Using class IDs got from registry

I got the class IDs associated with certain shell-related functions from the registry, like recycle bin cleaner, etc. I just want to know how to use them. To be more specific:
How to display the "Find" Dialog box knowing the ShellFind Class ID
How to empty the recycle bin using the Recycle bin cleaner class ID
and similar stuff...
Since these aren't folders, using a rooted explorer won't work. How do I do these things?
(If anyone can tell me how to do the same without using class IDs, that'll be great!!!)
