网页知道的并不多，不过似乎关于ActiveX控件在网页中的问题在所有关于ActiveX控件的问题中所占的比重相当的大，而其中最常问的就是，网页中弹出来的安全警告。
关于这个问题，并不复杂，网上搜索一下可以找到一大片的回答，真正的是天下文章一大抄了。

新建一控件tix
方法一：使用“组件类管理器（Component Categories Manager ）”将自身在客户机器上注册为安全。
1.在tix.cpp中
#include "objsafe.h"
#include "comcat.h"
2.在tix.cpp中添加控件的CLSID定义
const GUID CDECL CLSID_SafeItem =
{ 0x06aa1f79, 0x1874, 0x445c, { 0xb9, 0x0a, 0x23, 0x36, 0xb7, 0x39, 0xf2, 0x54 } };
// 注意这个GUID一定要与控件的CLSID相同！
// 可以从初始化类厂的宏中拷贝并整理
// IMPLEMENT_OLECREATE_EX(CTixCtrl, "TIX.TixCtrl.1",
// 0x6aa1f79, 0x1874, 0x445c, 0xb9, 0xa, 0x23, 0x36, 0xb7, 0x39, 0xf2, 0x54)
3.在tix.cpp中添加三个函数，用来将获得组件类管理器，并注册自己
// 创建组件种类
HRESULT CreateComponentCategory(CATID catid, WCHAR* catDescription)
{
ICatRegister* pcr = NULL;
HRESULT hr = S_OK;
hr = CoCreateInstance(CLSID_StdComponentCategoriesMgr,
NULL, CLSCTX_INPROC_SERVER, IID_ICatRegister, (void**)&pcr);
if (FAILED(hr))
return hr;
// Make sure the HKCR\Component Categories\{..catid...}
// key is registered.
CATEGORYINFO catinfo;
catinfo.catid = catid;
catinfo.lcid = 0x0409 ; // english
// Make sure the provided description is not too long.
// Only copy the first 127 characters if it is.
int len = wcslen(catDescription);
if (len>127)
len = 127;
wcsncpy(catinfo.szDescription, catDescription, len);
// Make sure the description is null terminated.
catinfo.szDescription[len] = '\0';
hr = pcr->RegisterCategories(1, &catinfo);
pcr->Release();
return hr;
}
// 注册组件种类
HRESULT RegisterCLSIDInCategory(REFCLSID clsid, CATID catid)
{
// Register your component categories information.
ICatRegister* pcr = NULL ;
HRESULT hr = S_OK ;
hr = CoCreateInstance(CLSID_StdComponentCategoriesMgr,
NULL, CLSCTX_INPROC_SERVER, IID_ICatRegister, (void**)&pcr);
if (SUCCEEDED(hr))
{
// Register this category as being "implemented" by the class.
CATID rgcatid[1] ;
rgcatid[0] = catid;
hr = pcr->RegisterClassImplCategories(clsid, 1, rgcatid);
}
if (pcr != NULL)
pcr->Release();
return hr;
}
// 卸载组件种类
HRESULT UnRegisterCLSIDInCategory(REFCLSID clsid, CATID catid)
{
ICatRegister* pcr = NULL ;
HRESULT hr = S_OK ;
hr = CoCreateInstance(CLSID_StdComponentCategoriesMgr,
NULL, CLSCTX_INPROC_SERVER, IID_ICatRegister, (void**)&pcr);
if (SUCCEEDED(hr))
{
// Unregister this category as being "implemented" by the class.
CATID rgcatid[1] ;
rgcatid[0] = catid;
hr = pcr->UnRegisterClassImplCategories(clsid, 1, rgcatid);
}
if (pcr != NULL)
pcr->Release();
return hr;
}
4.修改DllRegisterServer和DllUnregisterServer，以在注册控件的同时注册安全性
STDAPI DllRegisterServer(void)
{
AFX_MANAGE_STATE(_afxModuleAddrThis);
if (!AfxOleRegisterTypeLib(AfxGetInstanceHandle(), _tlid))
return ResultFromScode(SELFREG_E_TYPELIB);
if (!COleObjectFactoryEx::UpdateRegistryAll(TRUE))
return ResultFromScode(SELFREG_E_CLASS);
HRESULT hr;
// 标记控件初始化安全.
// 创建初始化安全组件种类
hr = CreateComponentCategory(CATID_SafeForInitializing,
L"Controls safely initializable from persistent data!");
if (FAILED(hr))
return hr;
// 注册初始化安全
hr = RegisterCLSIDInCategory(CLSID_SafeItem, CATID_SafeForInitializing);
if (FAILED(hr))
return hr;
// 标记控件脚本安全
// 创建脚本安全组件种类?
hr = CreateComponentCategory(CATID_SafeForScripting, L"Controls safely scriptable!");
if (FAILED(hr))
return hr;
// 注册脚本安全组件种类
hr = RegisterCLSIDInCategory(CLSID_SafeItem, CATID_SafeForScripting);
if (FAILED(hr))
return hr;
return NOERROR;
}
/////////////////////////////////////////////////////////////////////////////
// DllUnregisterServer - Removes entries from the system registry
STDAPI DllUnregisterServer(void)
{
AFX_MANAGE_STATE(_afxModuleAddrThis);
HRESULT hr;
// 删除控件初始化安全入口.
hr=UnRegisterCLSIDInCategory(CLSID_SafeItem, CATID_SafeForInitializing);
if (FAILED(hr))
return hr;
// 删除控件脚本安全入口
hr=UnRegisterCLSIDInCategory(CLSID_SafeItem, CATID_SafeForScripting);
if (FAILED(hr))
return hr;
if (!AfxOleUnregisterTypeLib(_tlid, _wVerMajor, _wVerMinor))
return ResultFromScode(SELFREG_E_TYPELIB);
if (!COleObjectFactoryEx::UpdateRegistryAll(FALSE))
return ResultFromScode(SELFREG_E_CLASS);
return NOERROR;
}
好了，这就OK了，接下来就可以在网页中试试了
方法二，让控件实现IObjectSafety接口
1.先用regsvr32 /u 卸载控件，其实是取消控件安全性的注册，然后注释掉上面我们添加的在DllRegisterServer和DllUnregisterServer中的控件安全性方面的注册代码。
2.在控件的tixctl.h中加入嵌套类声明
DECLARE_EVENT_MAP()
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);
END_INTERFACE_PART(ObjectSafety)
DECLARE_INTERFACE_MAP()
别忘了#include "objsafe.h"
3.在控件的tixctl.cpp中添加嵌套类实现
STDMETHODIMP CTixCtrl::XObjectSafety::GetInterfaceSafetyOptions(
REFIID riid,
DWORD __RPC_FAR *pdwSupportedOptions,
DWORD __RPC_FAR *pdwEnabledOptions)
{
METHOD_PROLOGUE_EX(CTixCtrl, ObjectSafety)
if (!pdwSupportedOptions || !pdwEnabledOptions)
{
return E_POINTER;
}
*pdwSupportedOptions = INTERFACESAFE_FOR_UNTRUSTED_CALLER | INTERFACESAFE_FOR_UNTRUSTED_DATA;
*pdwEnabledOptions = 0;
if (NULL == pThis->GetInterface(&riid))
{
TRACE("Requested interface is not supported.\n");
return E_NOINTERFACE;
}
// What interface is being checked out anyhow?
OLECHAR szGUID[39];
int i = StringFromGUID2(riid, szGUID, 39);
if (riid == IID_IDispatch)
{
// Client wants to know if object is safe for scripting
*pdwEnabledOptions = INTERFACESAFE_FOR_UNTRUSTED_CALLER;
return S_OK;
}
else if (riid == IID_IPersistPropertyBag
|| riid == IID_IPersistStreamInit
|| riid == IID_IPersistStorage
|| riid == IID_IPersistMemory)
{
// Those are the persistence interfaces COleControl derived controls support
// as indicated in AFXCTL.H
// Client wants to know if object is safe for initializing from persistent data
*pdwEnabledOptions = INTERFACESAFE_FOR_UNTRUSTED_DATA;
return S_OK;
}
else
{
// Find out what interface this is, and decide what options to enable
TRACE("We didn’t account for the safety of this interface, and it’s one we support...\n");
return E_NOINTERFACE;
}
}
STDMETHODIMP CTixCtrl::XObjectSafety::SetInterfaceSafetyOptions(
REFIID riid,
DWORD dwOptionSetMask,
DWORD dwEnabledOptions)
{
METHOD_PROLOGUE_EX(CTixCtrl, ObjectSafety)
OLECHAR szGUID[39];
// What is this interface anyway?
// We can do a quick lookup in the registry under HKEY_CLASSES_ROOT\Interface
int i = StringFromGUID2(riid, szGUID, 39);
if (0 == dwOptionSetMask && 0 == dwEnabledOptions)
{
// the control certainly supports NO requests through the specified interface
// so it’s safe to return S_OK even if the interface isn’t supported.
return S_OK;
}
// Do we support the specified interface?
if (NULL == pThis->GetInterface(&riid))
{
TRACE1("%s is not support.\n", szGUID);
return E_FAIL;
}
if (riid == IID_IDispatch)
{
TRACE("Client asking if it’s safe to call through IDispatch.\n");
TRACE("In other words, is the control safe for scripting?\n");
if (INTERFACESAFE_FOR_UNTRUSTED_CALLER == dwOptionSetMask && INTERFACESAFE_FOR_UNTRUSTED_CALLER == dwEnabledOptions)
{
return S_OK;
}
else
{
return E_FAIL;
}
}
else if (riid == IID_IPersistPropertyBag
|| riid == IID_IPersistStreamInit
|| riid == IID_IPersistStorage
|| riid == IID_IPersistMemory)
{
TRACE("Client asking if it’s safe to call through IPersist*.\n");
TRACE("In other words, is the control safe for initializing from persistent data?\n");
if (INTERFACESAFE_FOR_UNTRUSTED_DATA == dwOptionSetMask && INTERFACESAFE_FOR_UNTRUSTED_DATA == dwEnabledOptions)
{
return NOERROR;
}
else
{
return E_FAIL;
}
}
else
{
TRACE1("We didn’t account for the safety of %s, and it’s one we support...\n", szGUID);
return E_FAIL;
}
}
STDMETHODIMP_(ULONG) CTixCtrl::XObjectSafety::AddRef()
{
METHOD_PROLOGUE_EX_(CTixCtrl, ObjectSafety)
return (ULONG)pThis->ExternalAddRef();
}
STDMETHODIMP_(ULONG) CTixCtrl::XObjectSafety::Release()
{
METHOD_PROLOGUE_EX_(CTixCtrl, ObjectSafety)
return (ULONG)pThis->ExternalRelease();
}
STDMETHODIMP CTixCtrl::XObjectSafety::QueryInterface(
REFIID iid, LPVOID* ppvObj)
{
METHOD_PROLOGUE_EX_(CTixCtrl, ObjectSafety)
return (HRESULT)pThis->ExternalQueryInterface(&iid, ppvObj);
}
4.加入接口映射表中
在tixctl.h中加入声明
DECLARE_INTERFACE_MAP()
在tixctl.cpp中加入
BEGIN_INTERFACE_MAP(CTixCtrl, COleControl)
INTERFACE_PART(CTixCtrl, IID_IObjectSafety, ObjectSafety)
END_INTERFACE_MAP()
好了，试试，没问题了吧。
