IOleObject::EnumVerbs (Windows Embedded Compact 7)
Thismethodexposes a pull-down menu listing the verbs available for an object in ascending order by verb number.
HRESULT EnumVerbs( IEnumOleVerb** ppEnumOleVerb );
- ppEnumOleVerb
-
[out] Address of IEnumOLEVERB* pointer variable that receives the interface pointer to the new enumerator object.
Each time an object receives a call to EnumVerbs, it must increase the reference count on *ppEnumOleVerb.
The caller is responsible to call IUnknown::Release when it is done with *ppEnumOleVerb.
If an error occurs, *ppEnumOleVerb must be set to NULL.
To determine whether the platform supports this interface, see Determining Supported COM APIs.
Containers call this method to expose a pull-down menu of the verbs available for their embedded objects.
You might want your container to call EnumVerbs every time such a menu is selected to enable such objects as media clips, whose verbs might change while they are running, to update their menus.
The default verb for a media clip, for example, changes from "Play" before it is activated to "Stop" when it is running.
The default handler's implementation of EnumVerbs uses the registry to enumerate an object's verbs.
If an object application is to use the default handler's implementation, it should return OLE_S_USEREG.
The enumeration returned is of type IEnumOLEVERB. This interface provides access to instances of the OLEVERB structure.
