내 응용 프로그램에는 현재 2 개의 문서 유형이 있습니다. 내가 집중할 대상은 두 번째입니다. 내 응용 프로그램은 MFC MDI를 기반으로하는 3D 엔진 편집기입니다. 첫 번째 문서는 렌더링 윈도우입니다.이 윈도우는 hwnd를 추출하여 내 그래픽 클래스로 보내는 것이 간단하기 때문에 완벽하게 작동합니다. 그러나 두 번째 창 (스크립팅)은 (지금은) 풍부한 편집 권한이 있다고 가정합니다. 하지만 어떤 이유로 렌더링하지 않습니다 (실제로는 한 번만 : /).C++ MFC MDI View 렌더링

그리고 이것은 출력 무엇 현재 :
지금은 괜찮아 보이지만 만 한번 렌더링하면, 그것을 클릭하면 (richEdit) n 아무거나 일어날 것입니다, 또는 나가 richEdit에서 타자를 치는 것을 시도하는 경우에, 아무것도 일어나지 않을 것입니다. 그래서 궁금해 하네, 왜? 렌더링을 계속하거나 뷰를 업데이트하지 않는 이유는 무엇입니까?
고맙습니다.
