描述:
我现在刚在学习做actixex控件，现在遇到一个关于在web上面发布的问题急切希望得到高手的指点。我参考资料通过vs2003工具通过工程向导创建了一个mfc下的ActiveX控件，取名aaa,任何代码未添加。然后想试下该控件在web中的发布效果。于是我通过工具将该直接生成的控件插入到网页中取名default1.html，并和aaa.ocx文件一起放置在iis目录下。然后我通过regsvr32 /u 命令将该控件反注册。然后将我的ie的安全设置关于actixeX控件的设置全部开启。然后输入http://localhost/default1.html可以正常显示该控件。但是当我输入本机的ip地址或者在客户机上运行的时候总是出现一个红X。和前面输入http://localhost/default1.html相比会少一个提示是否允许交互。我通过vs2003里面的工具查看到该控件也在客户机上面安装成功了。调试了几天这个问题始终不能解决。请教csdn里面的高手能帮下我，不知道该问题到底出在哪里？
解决方案1:
什么红叉， 提示什么信息， 问题描述的清楚一点，
应该是安全接口 问题， 中加这些就可以了（适合mfc）
.h文件中加：
BEGIN_INTERFACE_PART(ObjectSafety, IObjectSafety)
STDMETHOD(GetInterfaceSafetyOptions)(REFIID riid, DWORD __RPC_FAR *pdwSupportedOptions, DWORD __RPC_FAR *pdwEnabledOptions);
STDMETHOD(SetInterfaceSafetyOptions)(REFIID riid, DWORD dwOptionSetMask, DWORD dwEnabledOptions);

STDMETHODIMP_(ULONG) your ctrl::XObjectSafety::AddRef()
{
METHOD_PROLOGUE_EX_(your ctrl, ObjectSafety)
return (ULONG)pThis->ExternalAddRef();

}
你的组件要实现IObjectSafety接口，具体加上下面两行：
class CXXX：public IObjectSafetyImpl<CFactory, INTERFACESAFE_FOR_UNTRUSTED_CALLER>,
COM_INTERFACE_ENTRY(IObjectSafety)
也就是你除了将安全属性设置成允许下载末签名的组件，还要设置一下允许下载末标记为安全的组件，否则你可以向上
