Please see my comment to the question. It should explain why the question makes no sense. Or it makes some sense for the library I don't know, but then this is not a part of .NET FCL.
I can only speculate that you meant something like
. Components are somewhat similar to controls, and some are not related to Windows API Windows and their handlers, such as
. You can create such components as the classes derived from
, but such components has nothing to do with controls, especially with user controls.
And by the way, my own opinion is that making such non-control classes the components which can be used with the designer was plain stupid. I can discuss this matter if someone will explain me how being a component helps to work with a timer of dialog, but so far no one tried. At the same time, I can explain why it's bad. I suspect, the only reason for that was marketing.
Happy New Year!
