在EOS6的项目中，如果采用VC++开发的ActiveX，那么第一次运行的时候，IE中就会提示，“在此页上的ActiveX控件和本页上的其他部分的交互可能不安全，你想允许这种交互吗？”在网上找了很多资料，原理介绍的多，但是真正如何做，介绍的比较少，因此这里把实际的步骤一步一步的记录下来了，供大家参考。
1.1 去除ActiveX访问时的安全提示
当ActiveX第一次被访问时，会出现如下提示框：
这是IE浏览器的安全机制造成的，我们可以采用下面的步骤来去除这个提示信息：
1.1.1 在CDemoCtl的头文件.h中增加对objsave的引用
#include <objsafe.h>
1.1.2 在其protected声明区增加如下内容：
1
//去掉安全警告 BEGIN
2
3DECLARE_INTERFACE_MAP()
4
5BEGIN_INTERFACE_PART(ObjectSafety, IObjectSafety)
6
7STDMETHOD(GetInterfaceSafetyOptions)(REFIID riid, DWORD __RPC_FAR *pdwSupportedOptions, DWORD __RPC_FAR *pdwEnabledOptions);
8
9STDMETHOD(SetInterfaceSafetyOptions)(REFIID riid, DWORD dwOptionSetMask, DWORD dwEnabledOptions);
10
11END_INTERFACE_PART(ObjectSafety)
12
13//去掉安全警告 END
1.1.3 在CDemoCtl的实现类.cpp的IMPLEMENT_DYNCREATE(CActivexFirstCtrl, COleControl)这一行后增加如下内容：
1//去掉安全警告 BEGIN
2BEGIN_INTERFACE_MAP(CAudioCommunicationCtrl, COleControl)
3
4 INTERFACE_PART(CAudioCommunicationCtrl, IID_IObjectSafety, ObjectSafety)
5
6END_INTERFACE_MAP()
