要标记一个MFC ActiveX控件为安全,可以仿照下面代码修改而得:
// CardScan.cpp : CCardScanApp 和DLL 注册的实现。 #include " stdafx.h " #include " CardScan.h " #include " comcat.h " #include " strsafe.h " #include " objsafe.h " CCardScanApp theApp; const GUID CDECL BASED_CODE _tlid = { 0x29959268 , 0x9729 , 0x458E , { 0xA8 , 0x39 , 0xBB , 0x39 , 0x2E , 0xCB , 0x7E , 0x37 } }; const WORD _wVerMajor = 1 ; const WORD _wVerMinor = 0 ; const CATID CLSID_SafeItem = { 0xB548F3C7 , 0x2135 , 0x4242 ,{ 0x92 , 0x0B , 0xA7 , 0xBD , 0xEE , 0x6D , 0x2B , 0xA3 }}; // { 0x36299202, 0x9ef, 0x4abf,{ 0xad, 0xb9, 0x47, 0xc5, 0x99, 0xdb, 0xe7, 0x78}}; // CCardScanApp::InitInstance - DLL 初始化 BOOL CCardScanApp::InitInstance() { BOOL bInit = COleControlModule::InitInstance(); if (bInit) { } return bInit; } // CCardScanApp::ExitInstance - DLL 终止 int CCardScanApp::ExitInstance() { return COleControlModule::ExitInstance(); } HRESULT CreateComponentCategory(CATID catid, CHAR * 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.

COleObjectFactoryEx::UpdateRegistryAll(FALSE)) return ResultFromScode(SELFREG_E_CLASS); return NOERROR; } 这里值得注意的一个地方是DllUnregisterServer函数,在这段代码中,我是将
hr = UnRegisterCLSIDInCategory(CLSID_SafeItem, CATID_SafeForInitializing); hr = UnRegisterCLSIDInCategory(CLSID_SafeItem, CATID_SafeForScripting); 这两句代码放在
if ( ! AfxOleUnregisterTypeLib(_tlid, _wVerMajor, _wVerMinor)) return ResultFromScode(SELFREG_E_TYPELIB); if ( ! COleObjectFactoryEx::UpdateRegistryAll(FALSE)) return ResultFromScode(SELFREG_E_CLASS); 这两句代码的前面,如果你查阅MSDN,将会发现它上面的顺序和我是相反的,这应该是微软的一个错误代码,如果按照MSDN的代码来写,则你使用regsvr32 -u CardScan.ocx反注册时会报下面的错误:
调整为我所说的顺序就没问题了。
