Hiding Properties and Events

If I've derived my component from another component and I don't want the user to be able to view properties or set handlers for events used by the base component, how on earth do I hide them from my new component.

My component is derived from the TClientSocket and I want to remove the Active property (and a few others), and also OnConnecting event (among others).

There is no legal way to 'unpublish' properties en methods that have been published in one of the ancestorclasses.
In this case you should derive from Tcustomsocket instead.
It's good practice to derive from a custom class if its present, because they are there precisely for the reason of visibility.
Here's what to do:
-Derive your class from Tcustomsocket
-Copy sourcecode from necessary members in Tclientsocket to your Tcustomsocket code.
-Make any members you want to be invisible protected, if you want to be able to use them only from the class or its derived classes, or public in case you want to use the members from outside the class or its derivatives.
