ICatalogObject::Key property

Applies to: desktop apps only

Retrieves the key property of the object.

This property is read-only.

Syntax

Copy

HRESULT get_Key(
  [out, retval]  VARIANT *pvarRetVal
);

Property value

The key property of the object.

Error codes

This method can return the standard return values E_INVALIDARG, E_OUTOFMEMORY, E_UNEXPECTED, E_FAIL, and S_OK.

Remarks

The key property serves as the primary identifier for a collection. In some cases, it is a GUID, such as CLSID for a component; in some cases, it is the object name, as with roles. The key property of a collection is identified in the documentation for each specific collection of the COM+ Administration Collections.

If you add a new object and save it with the key property of an existing object, you overwrite the existing object.
