강좌를 통해 간단히 DLL만드는건 배웠는데, 컴포넌트를 집어 넣으려니까 힘드네요
위에 처럼 하니까 OnRxChar이벤트 함수 입력하는곳에서 에러가 납니다
[DCC Error] ProtocolV4R0.dpr(514): E2009 Incompatible types: 'method pointer and regular procedure'
VCL폼 없이 만들려고 이렇게 해봤는데 폼이 있어야 할까요?

그리고..
DLL 소스에서 CPort를 Uses절에 놓으면 Cannot resolve 라고 에러가 나는데 이건 어떻게 해야 하나요?
VCL프로젝트 생성하고 폼에 CPort컴포넌트 올려놓고 했을때는 이런 에러가 없었는데 뭐가 빠진걸까요?
