如何实现对AX OCX的数字签名

你是要在IE里使用吧，在VC里很简单，不须注册：
这样就不会有提示了：
1:先添加三个全局函数
// Helper function to create a component category and associated description
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;
}

// Helper function to register a CLSID as belonging to a component category
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;
}

// Helper function to unregister a CLSID as belonging to a component category
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;
}

2:将控件类的UpdateRegistry(BOOL bRegister)函数替换如下：
BOOL CLCCBatmanCtrl::CLCCBatmanCtrlFactory::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 scripting");
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 initializing form 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_LCCBATMAN,
IDB_LCCBATMAN,
afxRegApartmentThreading,
_dwLCCBatmanOleMisc,
_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);
}
}
OK!
