Enum Persistence 

pub enum Persistence {
    NotPersistable = 0,
    Persistable = -1,
}

Represents the persistability of a file.

Only available when the class is part of an ActiveX DLL project that is both public and creatable.

Determines whether the class can be saved to disk.

If it is Persistable, then four procedures: InitProperties, ReadProperties, and WriteProperties events, and the PropertyChanged method are automatically added to the class module.

Without these procedures, the class cannot be saved to disk.

Variants

NotPersistable = 0

The class property cannot be saved to a file in a property bag. This value is stored as 0 (false) in the file.

Persistable = -1

The class property can be saved to a file in a property bag. This value is stored as -1 (true) in the file.
