XRValueCollection.CreateInstance(XRValueCollection * *) (Compact 2013)
3/28/2014
This method returns an instance of an XRValueCollection<ItemType> object that also supports functionality that resembles the Component Object Model (COM) and exposes interfaces defined in the inherited interface map to callers of XRObject.QueryInterface(const IID&,void * *).
Syntax
HRESULT CreateInstance(
XRValueCollection * * ppXRValueCollection)
Parameters
- ppXRValueCollection
[out] Pointer to an XRValueCollection<ItemType> instance that supports XRObject.QueryInterface(const IID&,void * *), XRObject.AddRef, XRObject.Release, and the interface entries in the interface map for the base class _XRValueCollectionBaseT<IFace,ItemType,ItemComparer,ItemConverter,ItemLifeManager>.

Remarks
In addition to supporting the methods inherited by XRValueCollection<ItemType>, the object instance in ppXRValueCollection supports the methods XRObject.QueryInterface(const IID&,void * *), XRObject.AddRef, and XRObject.Release, and also supports the following interfaces for callers of XRObject.QueryInterface(const IID&,void * *):
For more information about the interface map inherited by XRValueCollection<ItemType>, see _XRValueCollectionBaseT<IFace,ItemType,ItemComparer,ItemConverter,ItemLifeManager>.
This method uses the XRObject<Base> helper class to create the object instance.
