ActiveX控制注册为安全控件

要是ActiveX注册为安全控件，一定要继承IObjectSafety接口

首先，在项目Ctrl.h中引用

#include<objsafe.h>

然后

DECLARE_DYNCREATE(CKBPwdActiveXCtrl) 下面添加如下代码：
    DECLARE_INTERFACE_MAP()

    BEGIN_INTERFACE_PART(ObjSafe, IObjectSafety)

        STDMETHOD_(HRESULT, GetInterfaceSafetyOptions) (

        REFIID riid,

        DWORD __RPC_FAR *pdwSupportedOptions,

        DWORD __RPC_FAR *pdwEnabledOptions

        );



        STDMETHOD_(HRESULT, SetInterfaceSafetyOptions) (

            REFIID riid,

            DWORD dwOptionSetMask,

            DWORD dwEnabledOptions

            );

    END_INTERFACE_PART(ObjSafe);
    //---------------------------------------

这个是设置头文件完成，然后在其项目Ctrl.cpp中

在UpdateRegistry上面添加如下代码：
