ActiveX去除IE警告框方法

在classview下，向目录的第一个.h文件（即App启动头文件）中加入以下内容：

//创建Component Categories中的初始化安全和脚本安全项
HRESULT CreateComponentCategory(CATID catid, WCHAR* catDescription);
//在CLSID中创建与Component Categories中初始化安全和脚本安全项中相对应的implemented Categories项
HRESULT RegisterCLSIDInCategory(REFCLSID clsid, CATID catid);
//注销与CLSID中的相应implemented Categories项，一般用不到，因为其它程序可能也会用到这此项
HRESULT UnRegisterCLSIDInCategory(REFCLSID clsid, CATID catid);

extern const GUID CDECL _tlid;
extern const GUID CDECL CLSID_SafeItem;

extern const WORD _wVerMajor;
extern const WORD _wVerMinor;

在对就的.cpp文件中加入以下内容，如果原来程序中已经有的，只改动其中的多余部分即可：

//设置控件与注册表相关的类型库ID，后面跟有version(1.0)字样，从本工程的.idl文件中获取
const GUID CDECL BASED_CODE _tlid =
{ 0xB926A326, 0xBE91, 0x4337, { 0xA1, 0xDC, 0x76, 0x1B, 0x73, 0x15, 0x6B, 0x23 } };
//控件在注册表中的CLSID，后面跟有control字样，从本工程的.idl文件中获取
const GUID CDECL CLSID_SafeItem =
{ 0xAF546E3F, 0xB5B8, 0x42D6, {0xBB, 0x74, 0x84, 0xB7, 0x25, 0xC0, 0x38, 0x4D}};

const WORD _wVerMajor = 1;
const WORD _wVerMinor = 0;

加入以上代码后IE无任何警告。我的环境是XP SP2 + VC6.0
