The IPersistFileFormat interface is based on the standardinterface and augments it in the following ways:
Shows you how to properly specify a new, untitled file to themethod.
Shows you that the file should be opened as a read-only file.
Eliminates the unnecessary Save As prompt string from.
Returns an error code when(null) is called on an untitled object.
IPersistFileFormat provides enough information for the client of an object to implement the Save As dialog box—that is, to fill in the Save As Type drop-down list and manage the initial file extension but still give complete flexibility to the object. Thus, the object owns all aspects of its file and format, including the name of its format.
See illustrations of the implementation and/or calling of this interface in the samplesNotes to Implementers When saving documents or document editors that use the standard Save As dialog box implementation of the environment. , , , and .
