IOleObject::EnumVerbs
Exposes a pull-down menu listing the verbs available for an object in
ascending order by verb number.
HRESULT EnumVerbs(
IEnumOleVerb **ppEnumOleVerb
| //Ptr to storage of enumerator
| );
|
|
Parameter
ppEnumOleVerb
[out] Points to where the new enumerator should be returned. If an error is
returned, this parameter must be set to NULL. Each time an object receives a call
to EnumVerbs, it must increase the reference count on the pointer the method returns. It
is the caller's responsibility to call Release when it is done with the pointer.
Return Values
S_OK
Verb(s) enumerated successfully.
OLE_S_USEREG
Delegate to the default handler to use the entries in the registry to provide
the enumeration.
OLEOBJ_E_NOVERBS
Object does not support any verbs.
Comments
Notes to Callers
Containers call this method to expose a pull-down menu of the verbs available
for their embedded objects. You may want your container to call IOleObject::EnumVerbs each and every time such a menu is selected in order to enable such objects
as media clips, whose verbs may 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" once it is running.
Notes to Implementors
The default handler's implementation of IOleObject::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:
typedef Enum < OLEVERB > IEnumOLEVERB;
where OLEVERB is defined as:
typedef struct tagOLEVERB
{
LONG iVerb;
LPOLESTR lpszVerbName;
DWORD fuFlags;
DWORD grfAttribs;
} OLEVERB;
The following table describes the members of the OLEVERB structure:
OLEVERB Member
| Description
| iVerb
| Verb number being enumerated. If the object supports OLEIVERB_OPEN,
OLEIVERB_SHOW and/or OLEIVERB_HIDE (or another predefined verb), these will be the first
verbs enumerated, since they have the lowest verb numbers.
| lpszVerbName
| Name of the verb.
In Windows, this value, along with optional embedded ampersand characters to
indicate accelerator keys, can be passed to the AppendMenu function.
On the Macintosh, the following metacharacters may be passed along with this
value:
|
| - ! marks the menu item with the subsequent character
|
| - < sets the character style of the item
|
| |
| The metacharacters / and ^ are not permitted.
| fuFlags
| In Windows, a group of flags taken from the flag constants beginning with MF_
defined in AppendMenu. Containers should use these flags in building an object's verb menu. All
Flags defined in AppendMenu are supported except for:
|
| MF_BITMAP
|
| MF_OWNERDRAW
|
| | grfAttribs
| In Windows, a group of flag bits taken from the enumeration OLEVERBATTRIB. The flag OLEVERBATTRIB_NEVERDIRTIES indicates that executing this verb will
not cause the object to become dirty and is therefore in need of saving to
persistent storage.
OLEVERBATTRIB_ONCONTAINERMENU indicates that this verb should be placed on the
container's menu of object verbs when the object is selected. OLEIVERB_HIDE,
OLEIVERB_SHOW, and OLEIVERB_OPEN never have this value set.

.Net is powerful, but not all-powerful, so sometimes we need to use Win32 API for our .Net applications. It's simple enough with Platform Invoke if you have Win32 skill, but we do not always have time to dig the ancient documentation, declare the special types that are compatible with Win32, find the values of the Win32's constants and so on. Nostalgia .Net offers several simple-to-use classes, and components that will allow you to forget about the headache of Win32 and just use the power of Win32 in your application the same way as you use the native. Net classes. More » |
