Describes the steps in connecting an ActiveX control to a property page. 

To connect a property page to an ActiveX control:

1. Add DefinePropertyPage with the GUID constant of the property page as the parameter to the DefinePropertyPages method implementation in the control's implementation for the unit. For example, procedure TButtonX.DefinePropertyPages(DefinePropertyPage: TDefinePropertyPage); begin DefinePropertyPage(Class_PropertyPage1); >end; BEGIN_PROPERTY_MAP(TActiveFormXImpl) // Define property pages here. Property pages are defined using // the PROP_PAGE macro with the class id of the page. For example, // PROP_PAGE(CLSID_ActiveFormXPage) PROP_PAGE(CLSID_PropertyPage1) END_PROPERTY_MAP() The GUID constant, Class_PropertyPage1, of the property page can be found in the property pages unit. The GUID is defined in the property page's implementation unit .
2. Add the property page unit to the uses clause of the controls implementation unit.
