1.要加一个头文件:
         #include <objsafe.h>

2.在控件头文件中加入:

1 DECLARE_INTERFACE_MAP()
2 BEGIN_INTERFACE_PART(ObjectSafety, IObjectSafety)
3 STDMETHOD(GetInterfaceSafetyOptions)(REFIID riid, DWORD __RPC_FAR *pdwSupportedOptions, DWORD __RPC_FAR *pdwEnabledOptions);
4 STDMETHOD(SetInterfaceSafetyOptions)(REFIID riid, DWORD dwOptionSetMask, DWORD dwEnabledOptions);
5 END_INTERFACE_PART(ObjectSafety)


3.在控件的CPP文件中加入:

复制代码
  1 BEGIN_INTERFACE_MAP(CVP2PCtrl, COleControl)
2 INTERFACE_PART(CVP2PCtrl, IID_IObjectSafety, ObjectSafety)

//OK!不会再弹出那个“与ActiveX控件交互不安全“的对话框了~~~

//其中CVP2PCtrl全部要换成你的控件的类名
