Description
TCustomIniPropStorage is a TFormPropertyStorage descendant
which defines a class used to store form session properties to a file
using the INI format. It introduces properties and methods needed to access the
INI file used as the storage mechanism for the class.
Use the SessionPropperties property in the TForm or a TFrame instance which owns the class to define the components and property names stored using the storage mechanism.
Use IniFileName to specify the path and file name where session properties are stored in IniFile.
Use IniSection to specify the name for a section where session properties are stored. When omitted, session properties stored at the root level in IniFile.
Use Active to enable or disable read/write access to the INI file storage for the class instance.
Use the event handlers in the class to perform actions needed before or during save and restore operations using the session properties.
