IPersistStorage interface (objidl.h)
Enables a container application to pass a storage object to one of its contained objects and to load and save the storage object. This interface supports the structured storage model, in which each contained object has its own storage that is nested within the container's storage.
Inheritance
The IPersistStorage interface inherits from IPersist. IPersistStorage also has these types of members:
Methods
The IPersistStorage interface has these methods.
| IPersistStorage::HandsOffStorage Instructs the object to release all storage objects that have been passed to it by its container and to enter HandsOff mode. |
| IPersistStorage::InitNew Initializes a new storage object. |
| IPersistStorage::IsDirty Determines whether an object has changed since it was last saved to its current storage. |
| IPersistStorage::Load Loads an object from its existing storage. |
