    BOOL    LockFolder();

    --
    --   METHOD:   LockFolder                                  PUBLIC
    --
    --   PURPOSE:  Invalidates the current password, thereby locking the folder.
    --
    --   INVOKED:  From _wpMenuItemSelected
    --

    override wpInitData;

    --
    --   METHOD:   wpInitData                                  PUBLIC
    --
    --   PURPOSE:  Initializes instance data
    --
    --   INVOKED:  By Workplace Shell, upon instantiation of the object instance.
    --

    override wpModifyPopupMenu;

    --
    --   METHOD:   wpModifyPopupMenu                           PUBLIC
    --
    --   PURPOSE:  Adds an additional "Lock" item to the object's context menu.
    --
    --   INVOKED:  By Workplace Shell, upon instantiation of the object instance.
    --

    override wpMenuItemSelected;

    --
    --   METHOD:   wpMenuItemSelected                          PUBLIC
    --
    --   PURPOSE:  Processes the user's selections from the context menu.  The
    --             overridden method processes only the added "Lock" item, before
    --             invoking the parent's default processing to handle other items.
    --
    --   INVOKED:  By Workplace Shell, upon selection of a menu item by the user.
    --

    override wpOpen;

    --
    --   METHOD:   wpOpen                                      PUBLIC
    --
    --   PURPOSE:  Only allows a folder to be opened if the folder is unlocked, or
    --             if the user supplies the correct password in response to the
    --             dialog.
    --
    --   INVOKED:  By Workplace Shell, upon selection of the "Open" menu item by
    --             the user.
    --

    override wpSetTitle;

    --
    --   METHOD:   wpSetTitle                                  PUBLIC
    --
    --   PURPOSE:  Sets the folder's title (icon text) to have the phrase <Locked>
    --             as a suffix if the folder is locked, or removes this suffix if
    --             the folder is unlocked.
    --
    --   INVOKED:  By wpOpen to set the unlocked state, and by LockFolder to set
    --             the locked state.
    --

    override wpSetup;

    --
    --   METHOD:   wpSetup                                     PUBLIC
    --
    --   PURPOSE:  Sets folder properties based upon a setup string passed by the
    --             object's creator as part of the WinCreateObject() call.  The
    --             overridden method simply processes the PASSWORD keyword to set
    --             the folder's password immediately upon instantiation, before
    --             invoking the parent's default processing to handle all other
    --             keywords.
    --
    --   INVOKED:  By the Workplace Shell, upon instantiation of the object
    --             instance.
    --

    override wpSaveState;

    --
    --   METHOD:   wpSaveState                                 PUBLIC
    --
    --   PURPOSE:  Saves the object instance's persistent state data.  The
    --             overridden method simply saves the password data, then invokes
    --             the parent's default processing to handle any other instance
    --             data defined by ancestor classes.
    --
    --   INVOKED:  By the Workplace Shell, when the object becomes dormant.
    --

    override wpRestoreState;

    --
    --   METHOD:   wpRestoreState                              PUBLIC
    --
    --   PURPOSE:  Restores the object instance's persistent state data.  The
    --             overridden method simply restores the password data, then
    --             invokes the parent's default processing to handle any other
    --             instance data defined by ancestor classes.
    --
    --   INVOKED:  By the Workplace Shell, when the object becomes awake.
    --

    override wpSetIcon;

    --
    --   METHOD:   wpSetIcon                                   PUBLIC
    --
    --   PURPOSE:  This class method returns the handle to the correct icon for
    --             the object.
    --
    --   INVOKED:
    --

    override wpclsQueryTitle, class;

    --
    --   METHOD:   wpclsQueryTitle                             PUBLIC
    --
    --   PURPOSE:  This class method returns the default folder title for any
    --             instance of the password protected folder class.  This title
    --             is used if a title is not supplied in the WinCreateObject()
    --             call.
    --
    --   INVOKED:  By the Workplace Shell, upon instantiation of the object
    --             instance.
    --

    override wpclsInitData, class;

    --
    --   METHOD:   wpclsInitData                               PUBLIC
    --
    --   PURPOSE:  This class method allows the initialization of any class data
    --             items.  The overridden method simply obtains a module handle
    --             to be used when accessing Presentation Manager resources, then
    --             invokes the parent's default processing.
    --
    --   INVOKED:  By the Workplace Shell, upon loading the class DLL.
    --

    override wpclsQueryIcon, class;

    --
    --   METHOD:   wpclsQueryIcon                                 PUBLIC
    --
    --   PURPOSE:  This class method returns the handle to the default icon for
    --             the class.  This method is not used in the current version,
    --             but could be used if different icons are to be used for the
    --             locked and unlocked states.
    --
    --   INVOKED:
    --

    override wpclsUnInitData, class;

    --
    --   METHOD:   wpclsUnInitData                             PUBLIC
    --
    --   PURPOSE:  This class method allows the release of any class data items
    --             or resources.  The overridden method releases the module handle
    --             obtained by wpclsInitData, then invokes the parent's default
    --             processing.
    --
    --   INVOKED:  By the Workplace Shell, upon unloading the class DLL.
