IMoniker::IsRunning
Determines whether the object identified by this moniker is currently loaded
and running.
HRESULT IsRunning(
IBindCtx *pbc,
| //Bind context to be used
|
IMoniker *pmkToLeft,
| //Moniker to the left in the composite
|
IMoniker *pmkNewlyRunning
| //Moniker of a newly running object
|
);

Parameters
pbc
[in] Points to the bind context to be used in this binding operation. The bind
context caches objects bound during the binding process, contains parameters
that apply to all operations using the bind context, and provides the means by
which the moniker implementation should retrieve information about its
environment. For more information, see
IBindCtx.
pmkToLeft
[in] Points to the moniker to the left of this moniker if this moniker is part
of a composite. This parameter is primarily used by moniker implementors to
enable cooperation between the various components of a composite moniker; moniker
clients can usually pass NULL.
pmkNewlyRunning
[in] Points to the moniker most recently added to the Running Object Table
(ROT). This can be NULL. If non-NULL, the implementation can return the results of
calling
IMoniker::IsEqual on the
pmkNewlyRunning parameter, passing the current moniker. This parameter is intended to enable
IMoniker::IsRunning implementations that are more efficient than just searching the ROT, but the
implementation can choose to ignore
pmkNewlyRunning without causing any harm.
Return Values
S_OK
The moniker is running.
S_FALSE
The moniker is not running.
E_UNEXPECTED
Indicates an unexpected error.
Comments
Notes to Callers
If speed is important when you're requesting services from the object
identified by the moniker, you may want those services
only if the object is already running (because loading an object into the running
state may be time-consuming). In such a situation, you'd call
IMoniker::IsRunning to determine if the object is running.
For the monikers stored within linked objects,
IMoniker::IsRunning is primarily called by the default handler's implementation of
IOleLink::BindIfRunning.
Notes to Implementors
To get a pointer to the Running Object Table (ROT), your implementation should
call
IBindCtx::GetRunningObjectTable on the
pbc parameter. Your implementation can then call
IRunningObjectTable::IsRunning to determine whether the object identified by the moniker is running. Note
that the object identified by the moniker must have registered itself with the
ROT when it first began running.
