// MODULE: LOCALREGCONNECT.CPP
//
// PURPOSE: read - write to the registry; simulate this in some cases where Online TS uses
// registry, but Local TS doesn't
//
// COMPANY: Saltmine Creative, Inc. (206)-284-7511 support@saltmine.com
//
// AUTHOR: Oleg Kalosha, Joe Mabel
//
// ORIGINAL DATE: 8-24-98 in Online TS
//
// NOTES:
// 1. This file is for Local TS only
// 2. If we are moving toward a COM object at some point, we will probably have to establish an
// abstract class in lieu of CAPGTSRegConnector and have Online & Local TS's each derive their
// own version. Meanwhile (1/99), we share a common interface (defined in APGTSRegConnect.h)
// but implement it differently.
// 3. >>> WORK IN PROGRESS !!!! JM 1/19/98
