_XRValueCollectionBaseT.SetItemImpl(int,XRValue *) (Compact 7)
3/12/2014
This protected method implements collection operations that update objects in the collection.
Note
This method is reserved. In a derived class, call _XRValueCollectionBaseT.SetItem(int,XRValue *) instead of calling SetItemImpl.
Syntax
HRESULT STDMETHODCALLTYPE SetItemImpl(
int nIndex,
XRValue * pValue)
Parameters
- nIndex
[in] The index of the XRValue object in the collection to update with the new object.
- pValue
[in] Pointer to the new XRValue object.
Return Value
The following table shows the possible return values.

E_FAIL |

E_INVALIDARG |

Remarks
You can override the method implementation in a derived class, for example to add a notification that the collection changed.
To update a data source object in the _XRValueCollectionBaseT<IFace,ItemType,ItemComparer,ItemConverter,ItemLifeManager> collection, call the _XRValueCollectionBaseT.SetItem(int,XRValue *) method, which invokes SetItemImpl.
