Enables an object to be loaded from or saved to a disk file, rather than a storage object or stream. Because the information needed to open a file varies greatly from one application to another, the implementation of IPersistFile::Load on the object must also open its disk file.
Inheritance
The IPersistFile interface inherits from IPersist. IPersistFile also has these types of members:
Methods
The IPersistFile interface has these methods.
| IPersistFile::GetCurFile Retrieves the current name of the file associated with the object. If there is no current working file, this method retrieves the default save prompt for the object. |
| IPersistFile::IsDirty Determines whether an object has changed since it was last saved to its current file. |
| IPersistFile::Load Opens the specified file and initializes an object from the file contents. |
| IPersistFile::Save Saves a copy of the object to the specified file. |
| IPersistFile::SaveCompleted Notifies the object that it can write to its file. |
