IMHO you mix up 2 different approaches: old one - with VFP.COM utility and new one - with builtin VFP7 capabilities. To use new VFP7 features you have to declare your event-handling class with an enhanced DEFINE CLASS syntax. See more help on DEFINE CLASS in help (particularly IMPLEMENTS clause). You also don't need VFP.COM to build interface stencil - just use new ObjectBrowser, select your ClassLib (ActiveX) there, go to Interfaces branch and drag interface that you want to command window (or better to opened program code window) - it will build correct event handler class defenition to be used in conjunction with EventHandler() function.
