#ifndef _INC_DSKQUOTA_USER_H
#define _INC_DSKQUOTA_USER_H
///////////////////////////////////////////////////////////////////////////////
/* File: user.h
Description: Contains declarations for class DiskQuotaUser. The
DiskQuotaUser object represents a user's quota information on a
particular volume. Per-user quota information is managed through
the IDiskQuotaUser interface.
Revision History:
Date Description Programmer
-------- --------------------------------------------------- ----------
05/22/96 Initial creation. BrianAu
08/20/96 Added m_dwID member to DiskQuotaUser. BrianAu
09/05/96 Added domain name string and cache. BrianAu
08/25/97 Added OLE automation support. BrianAu
03/18/98 Replaced "domain", "name" and "full name" with BrianAu
"container", "logon name" and "display name" to
better match the actual contents. This was in
reponse to making the quota UI DS-aware. The
"logon name" is now a unique key as it contains
both account name and domain-like information.
i.e. "REDMOND\brianau" or "[email protected]".
