HowTo remove service in Windows

Sometimes it is necessary to remove service from the Service List in the Windows Managment Console.
In the past I used program, which I compiled from the MSDN's sources (MSDN Library - October 2001: Samples\VC98\sdk\winbase\winnt\service).

But I found another way: Windows XP contains special program SC.exe, which can communicates with the Service Controller and installed services (start, stop, remove, create, query, etc.).
After that I use this command in my shell scripts.

E.g.: for removal of MySQL service, execute command:
sc delete MySQL
(! You may restore MySQL service via command mysqld-nt.exe --install)

But if you want to do this from your C++ program, you may use sample's sources from MSDN.

Part of these is listed below:

service.c
...
void CmdRemoveService()
{
    SC_HANDLE   schService;
    SC_HANDLE   schSCManager;

    schSCManager = OpenSCManager(
                        NULL,                   // machine (NULL == local)
                        NULL,                   // database (NULL == default)
                        SC_MANAGER_ALL_ACCESS   // access required
                        );
    if ( schSCManager )
    {
        schService = OpenService(schSCManager, TEXT(SZSERVICENAME), SERVICE_ALL_ACCESS);

        if (schService)
        {
            // try to stop the service
            if ( ControlService( schService, SERVICE_CONTROL_STOP, &ssStatus ) )
            {
                _tprintf(TEXT("Stopping %s."), TEXT(SZSERVICEDISPLAYNAME));
                Sleep( 1000 );

                while( QueryServiceStatus( schService, &ssStatus ) )
                {
                    if ( ssStatus.dwCurrentState == SERVICE_STOP_PENDING )
                    {
                        _tprintf(TEXT("."));
                        Sleep( 1000 );
                    }
                    else
                        break;
                }

                if ( ssStatus.dwCurrentState == SERVICE_STOPPED )
                    _tprintf(TEXT("\n%s stopped.\n"), TEXT(SZSERVICEDISPLAYNAME) );
                else
                    _tprintf(TEXT("\n%s failed to stop.\n"), TEXT(SZSERVICEDISPLAYNAME) );

            }

            // now remove the service
            if( DeleteService(schService) )
                _tprintf(TEXT("%s removed.\n"), TEXT(SZSERVICEDISPLAYNAME) );
            else
                _tprintf(TEXT("DeleteService failed - %s\n"), GetLastErrorText(szErr,256));


            CloseServiceHandle(schService);
        }
        else
            _tprintf(TEXT("OpenService failed - %s\n"), GetLastErrorText(szErr,256));

        CloseServiceHandle(schSCManager);
    }
    else
        _tprintf(TEXT("OpenSCManager failed - %s\n"), GetLastErrorText(szErr,256));
}
