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 <ComCat.h>
#include <objsafe.h>重新编译，即可。
