//  HISTORY:
//  96/03/05  markdu  Created.
//  96/03/11  markdu  Added InetConfigClient()

//  96/03/12  markdu  Set connectoid for autodial if INETCFG_SETASAUTODIAL
//            is set.  Renamed ValidateConnectoidData to MakeConnectoid.
//  96/03/12  markdu  Added hwnd param to InetConfigClient() and
//            InetConfigSystem().
//  96/03/13  markdu  Added INETCFG_OVERWRITEENTRY.  Create unique neame
//            for connectoid if it already exists and we can't overwrite.

//  96/03/13  markdu  Added LPINETCLIENTINFO param to InetConfigClient()
//  96/03/16  markdu  Added INETCFG_INSTALLMODEM flag.
//  96/03/16  markdu  Use ReInit member function to re-enumerate modems.
//  96/03/19  markdu  Split export.h into export.h and csexport.h
//  96/03/20  markdu  Combined export.h and iclient.h into inetcfg.h
//  96/03/23  markdu  Replaced CLIENTINFO references with CLIENTCONFIG.
//  96/03/24  markdu  Replaced lstrcpy with lstrcpyn where appropriate.
//  96/03/25  markdu  Validate lpfNeedsRestart before using.
//  96/03/25  markdu  Clean up some error handling.
//  96/03/26  markdu  Use MAX_ISP_NAME instead of RAS_MaxEntryName 
//            because of bug in RNA.
//  96/03/26  markdu  Implemented UpdateMailSettings().
//  96/03/27  mmaclin InetGetProxy()and InetSetProxy().
//  96/04/04  markdu  NASH BUG 15610  Check for file and printer sharing
//            bound to TCP/IP .
//  96/04/04  markdu  Added phonebook name param to InetConfigClient,
//            MakeConnectoid, SetConnectoidUsername, CreateConnectoid,
//            and ValidateConnectoidName.
//  96/04/05  markdu  Set internet icon on desktop to point to browser.
//  96/04/06  mmaclin Changed InetSetProxy to check for NULL.
//  96/04/06  markdu  NASH BUG 16404 Initialize gpWizardState in

//            as the connection name, the entry is not changed.
//  96/04/18  markdu  NASH BUG 18443 Make exports WINAPI.

//  96/04/19  markdu  NASH BUG 17760 Do not show choose profile UI.
//  96/04/22  markdu  NASH BUG 18901 Do not set desktop internet icon to 
//            browser if we are just creating a temp connectoid.
//  96/04/23  markdu  NASH BUG 18719 Make the choose profile dialog TOPMOST.
//  96/04/25  markdu  NASH BUG 19572 Only show choose profile dialog if
//            there is an existing profile.
//  96/04/29  markdu  NASH BUG 20003 Added InetConfigSystemFromPath

//            if INETCFG_SUPPRESSINSTALLUI is set.
//  96/05/01  markdu  ICW BUG 8049 Reboot if modem is installed.  This is 
//            required because sometimes the configuration manager does not 
//            set up the modem correctly, and the user will not be able to
//            dial (will get cryptic error message) until reboot.
//  96/05/06  markdu  NASH BUG 21027  If DNS is set globally, clear it out so

//                INETCFG_INSTALLRNA - install RNA (if needed)
//                INETCFG_INSTALLTCP - install TCP/IP (if needed)
//                INETCFG_CONNECTOVERLAN - connecting with LAN (vs modem)
//                INETCFG_WARNIFSHARINGBOUND - Check if TCP/IP file sharing is
//                                            turned on, and warn user to turn
//                                            it off.  Reboot is required if
//                                            the user turns it off.
//                INETCFG_REMOVEIFSHARINGBOUND - Check if TCP/IP file sharing is
//                                              turned on, and force user to turn
