내 C++ 프로그램 내에 웹 페이지를 임베드하고 있습니다. 내가 실행중인 문제는 포함 된 페이지의 javascript 내에서 onkeypress를 캡처 할 수 있지만 onkeydown 및 onkeyup은 실행되지 않는다는 것입니다.임베디드 웹 컨트롤 (IWebBrowser2), 자바 스크립트의 onkeydown 및 onkeyup이 포함되지 않음
테스트 HTML을 내장되지 않은 IE (또는 Chrome) 창에서 보면 완벽하게 작동합니다. Internet Explorer 컨트롤에 포함 된 경우에만 문제가됩니다.
IE 윈도우 (또는 Spy ++ 사용)에 WndProc를 연결하면 WM_KEYDOWN, WM_CHAR 및 WM_KEYUP 메시지가 확실히 창에 표시됩니다.
나는 가능한 예제 코드로 최소한 만들려고 - 오류 검사를 많이 제거, 청소 등IE의 제어를 준비 할 때 저는 누락 된 일부 설정이 있습니까? 아니면 내장 된 IE를 사용할 때와 같은 방법입니까? 나는 설치가 없다면 모든 입력을 얻지 못할 것이라고 생각할 것이다.

IWebBrowser는 복합 창입니다. Spy ++에서 본 메시지 중 어느 창입니까? 그리고 브라우저 창에서 명시 적으로 포커스를 활성화/설정해야한다고 생각합니다. –
초점 창을 명시 적으로 설정하지 않고 놀았습니다. 또한 키 누르기 이벤트가 발생하기 때문에 초점 문제가 될 것 같지 않습니다. – Aaron
