Check out the documentation for IConnectionPointImpl and IConnectionPointContainerImpl. Your component needs to implement IConnectionPoint, and the Advise method will typically store the provided sink in some container (like an array, or a map, or a list...) When something happens in the component that triggers an event (such as changing a property, or a timer firing, or...) the component iterates through all the entries in that container, and calls the appropriate method(s) passing any parameters as required.

there is an m_vec member which contains a list of clients which the sinked the event.
