IMoniker::IsRunning

This method checks whether object is running.

At a Glance

Syntax

HRESULT IsRunning( IBindCtx * pbc, IMoniker * pmkToLeft,
IMoniker * pmkNewlyRunning );

Parameters

pbc

[in] Pointer to theIBindCtx interface on 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] Pointer to theIMoniker interface on the moniker to the left of this moniker if this moniker is part of a composite. This parameter is primarily used by moniker Implementers to enable cooperation between the various components of a composite moniker; moniker clients can usually pass NULL.

pmkNewlyRunning

[in] Pointer to theIMoniker interface on 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

The method supports the standard return value E_UNEXPECTED, as well as the  values described in the following table.

Remarks

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 Implementers

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.
