IBindCtx::GetRunningObjectTable (Compact 2013)
3/26/2014
This method provides an interface pointer to the Running Object Table for the computer on which this bind context is running.
The IBindCtx::GetRunningObjectTable method is supported in DCOM, but it is not supported in COM.
Calling this method in COM returns a value of E_NOTIMPL.
Syntax
HRESULT GetRunningObjectTable(
IRunningObjectTable** pprot
);
Parameters
pprot
[out] Address of the IRunningObjectTable* pointer variable that receives the interface pointer to the Running Object Table.If an error occurs, *pprot is set to NULL.
If *pprot is non-NULL, the implementation calls the IUnknown::AddRef method on the running table object.
It is the caller's responsibility to call the IUnknown::Release method.
Return Value
The following table shows the return values for this method.
Value |
Description |
|---|---|
E_OUTOFMEMORY |
A standard return value. |
CO_E_NOTINITIALIZED |
CoInitialize was not called. |
E_NOTIMPL |
This method is not implemented. |
S_OK |
A pointer to the Running Object Table was returned successfully. |
Remarks
The Running Object Table is a globally accessible table on each machine. It keeps track of all the objects that are currently running on the machine.
To determine whether the platform supports this interface, see Determining Supported COM APIs.
Notes to Callers
Typically, those implementing a new moniker class (through an implementation of IMoniker interface) call IBindCtx::GetRunningObjectTable.
It is useful to call this method in an implementation of the IMoniker::BindToObject or IMoniker::IsRunning method to check whether a given object is currently running.
You can also call this method in the implementation of the IMoniker::GetTimeOfLastChange method to learn when a running object was last modified.
Moniker implementations should call this method instead of using the GetRunningObjectTable function.
