Adding a COM Interface...

[dontknowitall]

I'm using ATL w/ Attributes and maybe w/ WTL (no MFC and WTL looks interesting). I am trying to figure out how CPTicker (here on CodeProject) was built and I'm stuck on figuring out how to add the IInputObject interface using VC++ .NET 2003. I managed to create an equivalent class (to CTickerBand) by right-clicking on the project->Add Class Wizard->ATL Simple Object. I switched to the Class View, found my newly added class, right-clicked, Implement Interface Wizard... Now what? Can't seem to find the IInputObject interface. It has been a while since I've messed with COM. I'm kind of surprised I remembered that much. And, for the kind soul, it would be nice to remind me on how to do the rest of these too: public IInputObject, public IPersistStreamInitImpl<CTickerBand>, public IContextMenu, public IDispatchImpl<ITickerWindow>, public CTickerWindowImpl
