OleRegEnumVerbs
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.
HRESULT OleRegEnumVerbs(
REFCLSID clsid,
| //Reference to class identifier
| LPENUMOLEVERB * ppenumOleVerb
| //Pointer to returned enumerator
| );
|
|
Parameters
clsid
Specifies the class whose verbs are being requested.
ppenumOleVerb
Points to where to return the enumeration.
Return Values
S_OK
Indicates the enumerator was returned successfully.
E_OUTOFMEMORY
Indicates there is insufficient memory to complete the operation.
OLEOBJ_E_NOVERBS
Indicates no verbs are registered for the class.
REGDB_E_CLASSNOTREG
Indicates no CLSID is registered for the class object.
REGDB_E_READREGDB
Indicates an error occurred reading the registry.
OLE_E_REGDB_KEY
Indicates the DataFormats/GetSet key is missing from the registry.
Comments
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.
The OleRegEnumVerbs function and its sibling functions, OleRegGetUserType, OleRegGetMiscStatus, 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.
