ActiveX를 만들었는데, 레지스트리나 시스템 파일 등...의 기능이 포함되어 있을 경우,
" 이 페이지의 ActiveX 컨트롤이 다른 부분과 상호 작용하는데 안전하지 않을 수 있습니다.
상호 작용을 허용하시겠습니까? "
와 같은 메시지가 뜨게 됩니다.
이 경우,
아래와 같이 안정성 처리(IObjectSafety)를 추가해줘야 합니다.
1. Ctrl 클래스의 헤더파일(h)에 추가해줍니다.
: 색으로 표시된 부분 과감히 CTRL+C, CTRL+V 하시면 됩니다. ^^;... (MS 문서 참조)
#include <objsafe.h>

2. Ctrl 클래스의 소스파일(cpp)에 추가해줍니다.

. MS 자료나 인터넷이나 다 이렇게 정형화(?) 되어 있습니다.
