TOleControl is the base class from which ActiveX controls are derived.
TOleControl = class(TWinControl, IUnknown, IOleClientSite, IOleControlSite, IOleInPlaceSite, IOleInPlaceFrame, IDispatch, IPropertyNotifySink, ISimpleFrameSite, IServiceProvider);
class TOleControl : public TWinControl, public IUnknown, public IOleClientSite, public IOleControlSite, public IOleInPlaceSite, public IOleInPlaceFrame, public IDispatch, public IPropertyNotifySink, public ISimpleFrameSite, public IServiceProvider;
TOleControl is derived from TWinControl and handles the interactions with COM necessary for using ActiveX controls. Most application do not need to explicitly derive a component from this class.
