一: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; }
二: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); } }
