ITuningSpaceContainer::put_Item method (tuner.h)
[The feature associated with this page, Microsoft TV Technologies, is a legacy feature. Microsoft strongly recommends that new code does not use this feature.]
The put_Item method saves changes to an existing tuning space in the collection.

[in] VARIANT varIndex,
[in] ITuningSpace *TuningSpace
);
Parameters
[in] varIndex
VARIANT that specifies the index of the tuning space.

If the method fails, error information can be retrieved using the standard COM IErrorInfo interface.
Remarks
An application can retrieve an existing tuning space from the collection, modify its properties by calling ITuningSpace methods, and then call put_Item to save the changes. The unique name property on the tuning space must match the tuning space at the specified index in the collection; otherwise, the method returns E_INVALIDARG.
To add a new tuning space, use the ITuningSpaceContainer::Add method.
