Hmmm. I've just taken a look, and I don't think it's possible. Thing is, when I wrote that article, I was targeting MFC Win32 applications. You can override CWinApp::Run just fine, but that's because CWinApp is derived from CWinThread (ie. it gets called every cycle). The COleControl class, on the other hand, isn't derived from CWinThread, it's derived from CWnd. That means you can't use the technique in my article there because CWnd is completely event-driven. To put it another way, any program which uses your ActiveX control would have to specifically update it every cycle. And I don't think you can do that with an ActiveX control. I think they're event-driven, so you'll have to stick with the OnIdle messages. I could be wrong, though; I've never written an MFC ActiveX control doing what you're doing.
