Description

IPersistStreamInitImpl::GetClassID

Retrieves the object's CLSID.

IPersistStreamInitImpl::GetSizeMax

Retrieves the size of the stream needed to save the object's data. The ATL implementation returns E_NOTIMPL.

IPersistStreamInitImpl::InitNew

Initializes a newly created object.

IPersistStreamInitImpl::IsDirty

Checks whether the object's data has changed since it was last saved.

IPersistStreamInitImpl::Load

Loads the object's properties from the specified stream.

IPersistStreamInitImpl::Save

Remarks

The IPersistStreamInit interface allows a client to request that your object loads and saves its persistent data to a single stream. Class IPersistStreamInitImpl provides a default implementation of this interface and implements IUnknown by sending information to the dump device in debug builds.
