Saves an object, and any nested objects that it contains, into the specified storage object. The object enters NoScribble mode.
HRESULT Save( IStorage *pStgSave, BOOL fSameAsLoad );
An IStorage pointer to the storage into which the object is to be saved.
Indicates whether the specified storage is the current one, which was passed to the object by one of the following calls: IPersistStorage::InitNew, IPersistStorage::Load, or IPersistStorage::SaveCompleted.
This parameter is set to FALSE when performing a Save As or Save A Copy To operation or when performing a full save. In the latter case, this method saves to a temporary file, deletes the original file, and renames the temporary file.
This parameter is set to TRUE to perform a full save in a low-memory situation or to perform a fast incremental save in which only the dirty components are saved.
This method can return the following values.
||The method completed successfully.|
||The object was not saved because of a lack of space on the disk.|
||The object could not be saved due to errors other than a lack of disk space.|
This method saves an object, and any nested objects it contains, into the specified storage. It also places the object into NoScribble mode. Thus, the object cannot write to its storage until a subsequent call to the IPersistStorage::SaveCompleted method returns the object to Normal mode.
If the storage object is the same as the one it was loaded or created from, the save operation may be able to write incremental changes to the storage object. Otherwise, a full save must be done.
This method does not call the IStorage::Commit method. Nor does it write the CLSID to the storage object. Both of these tasks are the responsibilities of the caller.OleSave helper function which performs the following steps:
- Call the WriteClassStg function to write the class identifier for the object to the storage.
- Call the IPersistStorage::Save method.
- If needed, call the IStorage::Commit method on the storage object.
If an embedded object passes the IPersistStorage::Save method to its nested objects, it must receive a call to its IPersistStorage::SaveCompleted method before calling this method for its nested objects.
