서비스 구성 변경

서비스 구성 프로그램은ChangeServiceConfig 및 ChangeServiceConfig2 함수를 사용하여 설치된 서비스의 구성 매개 변수를 변경합니다. 프로그램은 서비스 개체에 대한 핸들을 열고 해당 구성을 수정한 다음 서비스 개체 핸들을 닫습니다.

다음 예제에서 DoDisableSvc 함수는 ChangeServiceConfig 를 사용하여 서비스 시작 유형을 "Disabled"로 변경하고, DoEnableSvc 함수는 ChangeServiceConfig 를 사용하여 서비스 시작 유형을 "사용"으로 변경하고, DoUpdateSvcDesc 함수는 ChangeServiceConfig2 를 사용하여 서비스 설명을 "테스트 설명입니다"로 설정합니다. szSvcName 변수는 서비스 이름을 포함하는 전역 변수입니다. 이 변수를 설정하는 전체 예제는 SvcConfig.cpp를 참조하세요.
