Returns an enumeration of the registered verbs for the specified class.
Developers of custom DLL object applications use this function to emulate the
behavior of the default object handler.
| REFCLSID clsid,
||//Reference to class identifier
| LPENUMOLEVERB * ppenumOleVerb
||//Pointer to returned enumerator
Specifies the class whose verbs are being requested.
Points to where to return the enumeration.
Indicates the enumerator was returned successfully.
Indicates there is insufficient memory to complete the operation.
Indicates no verbs are registered for the class.
Indicates no CLSID is registered for the class object.
Indicates an error occurred reading the registry.
Indicates the DataFormats/GetSet key is missing from the registry.
Object applications can ask OLE to enumerate supported verbs in one of two
ways. One way is to call OleRegEnumVerbs
. The other way is to return OLE_S_USEREG in response to calls by the default
object handler to IOleObject::EnumVerbs
. OLE_S_USEREG instructs the default handler to call OleRegEnumVerbs
. Because DLL object applications cannot return OLE_S_USEREG, they must call OleRegEnumVerbs
rather than delegating the job to the object handler.
and its sibling functions, OleRegGetUserType
, and OleRegEnumFormatEtc
, provide a way for developers of custom DLL object applications to emulate
the behavior of OLE's default object handler in getting information about objects
from the registry. By using these functions, you avoid the considerable work
of writing your own, and the pitfalls inherent in working directly in the
registry. In addition, you get future enhancements and optimizations of these
functions without having to code them yourself.
