이런 에러가나오네요 다이렉트 드로우 쓰는데
컴파일하면 에러메시지가떠요 위에처럼요
왜 저런에러가나온는지 알고싶어요

초기화와  종료 함수는 이렇게 해두고

dll 에서 초기화 하고 종료 함수쓰고 해도 위메시지뜨고요
실행 프로젝트에 사용해도 에러메시지떠요
첫번쩨 서피스에 dc를 가저와서 그림을 뿌리게해놨거든요
혹시 CreateCompatibleDc 함수를 써서 해야되는건가요?
왜 에러메시지가 뜨는지 알고싶어요

실행 프로젝트에쓰면 그림은 뿌려지는데 종료할때 바이얼레이션 에러뜨네요
dll에 하면 실행때부터 바이얼레이션뜨고요
왜그럴가요?
