Groups 및 Users Append, ChangePassword 메서드 예제(VC++)

이 예제에서는 시스템에 새 Group 및 새 User를 추가하여 Groups의 Append 메서드와 Users의 Append 메서드를 보여 줍니다. 새 Group이 새 User의 Groups 컬렉션에 추가됩니다. 따라서 새 User가 Group에 추가됩니다. 또한 ChangePassword 메서드는 User 암호를 지정하는 데 사용됩니다.

참고

Windows 인증을 지원하는 데이터 원본 공급자에 연결하는 경우 연결 문자열의 사용자 ID 및 암호 정보 대신 Trusted_Connection=yes 또는 Integrated Security=SSPI를 지정해야 합니다.
