안녕하세요 Plutonix, 헤더 이름이 없습니다. 그렇다면 코드를 계속 사용할 수 있습니까? – RalJans
+1 멋진! 섹션을 읽는 API 함수가있을 수 있다고 상상 한 적이 없습니다. – ElektroStudios
SectionNames는 헤더라고 부릅니다. Read/WriteINI 함수에 대한 첫 번째 인수가 있습니다. 항목 정보를 얻으려면 SECTION Name이 필요하므로 목록 상자에 그냥 게시 할 수 있습니다. (내 코드가 아닌 kernel32 선언) @ElektroStudios, 이것은 Sections의 이름을 가져 오지만, Section'GetPrivateProfileSection'을 얻는 방법이 있습니다.하지만 이름을 알고 문자열을 파싱하여 값을 가져와야합니다. – Plutonix
