Restores the state of the component.
HRESULT LoadHistory( IStream *pStream, IBindCtx *pbc );
- [in] A pointer to an interface on the stream from which the object loads its persistent state.
- [in] A pointer to an interface on a bind context. The bind context is used in binding operations to restore the component's state and is passed to any objects contained by the component, if a binding is to be performed by the contained component.
Returns one of the following values.
S_OK The component was able to reload its persistent state. E_FAIL The component was unable to reload its persistent state. E_OUTOFMEMORY There was not enough memory to reload the persistent state of the component. E_POINTER The stream or the bind context supplied by the container was invalid.
The container calls IPersistHistory::LoadHistory to request that the component restore its state.
The component should never add a reference to the supplied stream. The stream should not be cached by the component.
