BindMoniker function (objbase.h)
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(
[in] LPMONIKER pmk,
[in] DWORD grfOpt,
[in] REFIID iidResult,
[out] LPVOID *ppvResult
);
Parameters
[in] pmk
A pointer to the object's moniker. See IMoniker.
[in] grfOpt
This parameter is reserved for future use and must be 0.
[in] iidResult
The interface identifier to be used to communicate with the object.
[out] ppvResult
The address of pointer variable that receives the interface pointer requested in iidResult. Upon successful return, *ppvResult contains the requested interface pointer. If an error occurs, *ppvResult is NULL. If the call is successful, the caller is responsible for releasing the pointer with a call to the object's IUnknown::Release method.
Return value
This function can return the following error codes, or any of the error values returned by the IMoniker::BindToObject method.
| Return code | Description |
|---|---|
|
The object was located and activated, if necessary, and a pointer to the requested interface was returned. |
|
The object that the moniker object identified could not be found. |
Remarks
BindMoniker is 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 that object's interfaces. BindMoniker packages the following calls:
CreateBindCtx(0, &pbc);
pmk->BindToObject(pbc, NULL, riid, ppvObj);
CreateBindCtx creates a bind context object that supports the system implementation of IBindContext. The pmk parameter is actually a pointer to the IMoniker implementation on a moniker object. This implementation's BindToObject method 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::BindToObject method directly, which enables you to use the same bind context object for all the monikers. See the IBindCtx interface 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 IMoniker methods. Instead, the client manipulates the linked objects through the IOleLink interface. The default handler implements this interface and calls the appropriate IMoniker methods as needed.
