关于证书的问题，不再本文章的范畴之内。其实这是很简单的事情，只要注册表加入类似的就可以 HKEY_CLASSES_ROOT\Component Categories\{7DD95801-9882-11CF-9FA9-00AA006C42C4}
HKEY_CLASSES_ROOT\Component Categories\{7DD95802-9882-11CF-9FA9-00AA006C42C4}
HKEY_CLASSES_ROOT\CLSID\{"your controls GUID"}\Implemented Categories\{7DD95801-9882-11CF-9FA9-00AA006C42C4}
HKEY_CLASSES_ROOT\CLSID\{"your controls GUID"}\Implemented Categories\{7DD95802-9882-11CF-9FA9-00AA006C42C4}
7DD95801-9882-11CF-9FA9-00AA006C42C4为安全空间的ID。如果是ATL的工程，很简单需要在控件中实现IObjectSafety接口，class CLoginCtl : .... , public IObjectSafetyImpl<CLoginCtl, INTERFACESAFE_FOR_UNTRUSTED_CALLER | INTERFACESAFE_FOR_UNTRUSTED_DATA> { ... BEGIN_COM_MAP(CLoginCtl) COM_INTERFACE_ENTRY(IObjectSafety) END_COM_MAP() ... } 或者BEGIN_CATEGORY_MAP(CLoginCtl) IMPLEMENTED_CATEGORY(CATID_SafeForInitializing) msdn http://support.microsoft.com/kb/168371/en-us
mfc的ocx加入msdn的一段程序就行了。msdn http://support.microsoft.com/kb/161873/en-usconst CATID CLSID_SafeItem ={0xa709093a, 0x22f9, 0x4bea,{0xa5, 0xfb, 0x12, 0x24, 0xf2, 0x83, 0xff, 0xbb}};
