Well, while I now understand what is an interface, I don't really understand the benefit of using it. For example, we use classes for grouping codes, but there is no code in the interface. The only good thing of interfaces, in my opinion, is that the parameters must be entered only once rather than for every place (is it really useful?). May I ask you for a simple example where interface is the only way to solve a problem? _______________________________________________ Unsubscribe or switch delivery mode: <http://www.realsoftware.com/support/listmanager/> Search the archives: <http://support.realsoftware.com/listarchives/lists.html>
