/* File: options.cpp
Description: Displays a property-sheet-like dialog containing
optional settings for CSC.
Classes:
COfflineFilesPage - Contains basic CSC settings. Designed
to be dynamically added to the shell's View->Folder Options
property sheet.
CustomGOAAddDlg - Dialog for adding custom go-offline actions to
the "advanced" dialog.
CustomGOAEditDlg - Dialog for editing custom go-offline actions
in the "advanced" dialog.
CscOptPropSheetExt - Shell property sheet extension object for
adding the COfflineFilesPage to the shell's View->Folder Options
property sheet.
Revision History:
Date Description Programmer
-------- --------------------------------------------------- ----------
12/03/97 Initial creation. BrianAu
05/28/97 Removed CscOptPropSheet class. Obsolete. BrianAu
Renamed AdvancedPage to CAdvOptDlg. This better
reflects the new behavior of the "advanced" dlg
as a dialog rather than a property page as first
designed.
07/29/98 Removed CscOptPropPage class. Now we only have BrianAu
a single prop page so there was no reason for
a common base class implementation. All base
class functionality has been moved up into the
COfflineFilesPage class.
Renamed "GeneralPage" class to "COfflineFilesPage"
to reflect the current naming in the UI.
08/21/98 Added PurgeCache and PurgeCacheCallback. BrianAu
08/27/98 Options dialog re-layout per PM changes. BrianAu
- Replaced part/full sync radio buttons with cbx.
- Added reminder balloon controls.
03/30/00 Added support for cache encryption. BrianAu
