为ActiveX控件增加安全认证

首先在工程名Ctrl.cpp文件中增加这三个函数

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; 
	}
	CATEGORYINFO catinfo; 
	catinfo.catid = catid; 
	catinfo.lcid = 0x0409 ; // english 
	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; 
} 


HRESULT RegisterCLSIDInCategory(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)) 
	{ 
		CATID rgcatid[1] ; 
		rgcatid[0] = catid; 
		hr = pcr->RegisterClassImplCategories(clsid, 1, rgcatid); 
	} 
	if (pcr != NULL) 
		pcr->Release(); 
	return hr; 
} 

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; 
}

然后修改这个文件中的UpdateRegistry函数

BOOL CXXXXCtrl::CXXXXCtrlFactory::UpdateRegistry(BOOL bRegister)
{
	// TODO: Verify that your control follows apartment-model threading rules.
	// Refer to MFC TechNote 64 for more information.
	// If your control does not conform to the apartment-model rules, then
	// you must modify the code below, changing the 6th parameter from
	// afxRegApartmentThreading to 0.

	if (bRegister)
	{
		HRESULT hr = S_OK ; 
		// register as safe for scripting 
		hr = CreateComponentCategory(CATID_SafeForScripting, 
			L"Controls that are safely scriptable"); 
		if (FAILED(hr)) 
		{
			return FALSE; 
		}
		hr = RegisterCLSIDInCategory(m_clsid, CATID_SafeForScripting); 
		if (FAILED(hr)) 
		{
			return FALSE; 
		}
		// register as safe for initializing 
		hr = CreateComponentCategory(CATID_SafeForInitializing, 
			L"Controls safely initializable from persistent data"); 
		if (FAILED(hr)) 
		{
			return FALSE; 
		}
		hr = RegisterCLSIDInCategory(m_clsid, CATID_SafeForInitializing); 
		if (FAILED(hr)) 
		{
			return FALSE; 
		}
		return AfxOleRegisterControlClass(
			AfxGetInstanceHandle(),
			m_clsid,
			m_lpszProgID,
			IDS_XXXX, 
			IDB_XXXX,
			afxRegApartmentThreading,
			_dwTvWallOleMisc,
			_tlid,
			_wVerMajor,
			_wVerMinor);
	}
	else
	{
		HRESULT hr = S_OK ; 
		hr = UnRegisterCLSIDInCategory(m_clsid, CATID_SafeForScripting); 
		if (FAILED(hr)) 
		{
			return FALSE; 
		}
		hr = UnRegisterCLSIDInCategory(m_clsid, CATID_SafeForInitializing); 
		if (FAILED(hr)) 
		{
			return FALSE; 
		}
		return AfxOleUnregisterClass(m_clsid, m_lpszProgID);
	}
}

最后别忘了包含两个头文件

#include  
#include 

重新编译，即可。
