This function locates an object by means of its moniker, activates the object if it is inactive, and retrieves a pointer to the specified interface on that object.
Syntax
HRESULT BindMoniker( LPMONIKER pmk, DWORD grfOpt, REFIID iidResult, LPVOID FAR* ppvResult ); |
Parameters
- pmk
-
[in] Pointer to the object's moniker.
- grfOpt
-
[in] Reserved for future use; must be zero.
- iidResult
-
[in] Interface identifier to be used to communicate with the object.
- ppvResult
-
[out] Address of pointer variable that receives the interface pointer requested in iidResult.
Upon successful return, * ppvResultcontains the requested interface pointer.
If an error occurs, * ppvResultis NULL.
If the call is successful, the caller is responsible for releasing the pointer with a call to the object's IUnknown::Release.
Return Value
- S_OK
-
The object was located and activated, if necessary, and that a pointer to the requested interface was returned.
- MK_E_NOOBJECT
-
The object that the moniker object identified could not be found.
This function can also return any of the error values returned by the IMoniker::BindToObjectmethod.
Remarks
BindMonikeris a helper function supplied as a convenient way for a client that has the moniker of an object to obtain a pointer to one of its interfaces. The BindMonikerfunction packages calls to CreateBindCtxand BindToObject.
CreateBindCtxcreates a bind context object that supports the system implementation of IBindContext. The pmkparameter is actually a pointer to the IMonikerimplementation on a moniker object. This implementation's BindToObjectmethod supplies the pointer to the requested interface pointer.
If you have several monikers to bind in quick succession, and if you know that those monikers will activate the same object, it may be more efficient to call the IMoniker::BindToObjectmethod directly, which allows you to use the same bind context object for all the monikers. See the IBindCtxinterface for more information.
Container applications that allow their documents to contain linked objects are a special client that generally does not make direct calls to IMonikermethods. Instead, the client manipulates the linked objects through the IOleLinkinterface.
The default handler implements this interface and calls the appropriate IMonikermethods as needed.
