FileNewOther...New COM Object 

The Interface Selection wizard is accessed by clicking the List button on the New COM Object wizard. The Interface Selection wizard lets you select a predefined dual or custom interface that you want to implement with a COM object you are creating. The selected interface becomes the default interface of the newly created COM object. The COM object wizard adds skeletal method implementations for all the methods on this interface to the generated implementation unit. You can then fill in the bodies of these methods to provide an implementation of the interface.

Item	Description
Interface list	The wizard lists all the interfaces defined in registered type libraries. You can select any dual or custom interface from this list. Each interface is prefixed with the name of the file that contains its type library. This can be an executable (.exe), a library (.dll or .ocx), or a type library file (.tlb).
Search	Enter a search string. The interface list automatically includes only those interfaces that match your search string. Click X to clear the search string.
Add Library	If the desired interface is in a type library that is not currently registered, click the Add Library button, navigate to the type library that contains the interface you want, and click OK. This registers the selected type library and refreshes the interface list in the Interface Selection wizard.
