VS6에서 ActiveX 만들고 페이지에 링크시켰지만, 메소드가 없다는 스크립트 에러가 나온다.

ActiveX의 ctrl.h파일에...아래 내용 추가

#include <objsafe.h>

    DECLARE_INTERFACE_MAP()
       
        BEGIN_INTERFACE_PART(ObjSafe, IObjectSafety)
        STDMETHOD_(HRESULT, GetInterfaceSafetyOptions) (
        /* [in] */ REFIID riid,
        /* [out] */ DWORD __RPC_FAR *pdwSupportedOptions,
        /* [out] */ DWORD __RPC_FAR *pdwEnabledOptions
        );
   
    STDMETHOD_(HRESULT, SetInterfaceSafetyOptions) (
        /* [in] */ REFIID riid,
        /* [in] */ DWORD dwOptionSetMask,
        /* [in] */ DWORD dwEnabledOptions
        );
    END_INTERFACE_PART(ObjSafe);

그리고 CPP파일에 아래 내용 추가.

}

위 코드를 추가하지 않았을 경우, IE 버전별로 반응하는 것이 틀린데...IE6의 경우 ActiveX의 실행을 묻게되고, IE8의 경우 실행할 수 있는 메소드가 없다고 나와버린다. 즉 스크립트 에러가 나온다. 위 코드를 꼭 추가해주자. 수동으로 해줘야 한다.
