2.修改DllRegisterServer函数:

STDAPI DllRegisterServer(void)
{
    HRESULT hr;    // HResult used by Safety Functions
    AFX_MANAGE_STATE(_afxModuleAddrThis);
    if (!AfxOleRegisterTypeLib(AfxGetInstanceHandle(), _tlid))
      return ResultFromScode(SELFREG_E_TYPELIB);
    if (!COleObjectFactoryEx::UpdateRegistryAll(TRUE))
      return ResultFromScode(SELFREG_E_CLASS);
    // 为初始化标记控件为安全控件
    hr = CreateComponentCategory(CATID_SafeForInitializing,
         L"Controls safely initializable from persistent data!");
    if (FAILED(hr))
      return hr;
    hr = RegisterCLSIDInCategory(CLSID_SafeItem,
         CATID_SafeForInitializing);
    if (FAILED(hr))
        return hr;
   // 为脚本标记控件为安全控件
    hr = CreateComponentCategory(CATID_SafeForScripting,                                 L"Controls safely  scriptable!");
    if (FAILED(hr))
        return hr;
    hr = RegisterCLSIDInCategory(CLSID_SafeItem,                         CATID_SafeForScripting);
    if (FAILED(hr))
        return hr;
    return NOERROR;
}

3.修改 DllUnregisterServer函数：

STDAPI DllUnregisterServer(void)
{
    HRESULT hr;    // HResult used by Safety Functions
    AFX_MANAGE_STATE(_afxModuleAddrThis);
    if (!AfxOleUnregisterTypeLib(_tlid, _wVerMajor, _wVerMinor))
      return ResultFromScode(SELFREG_E_TYPELIB);
    if (!COleObjectFactoryEx::UpdateRegistryAll(FALSE))
      return ResultFromScode(SELFREG_E_CLASS);
    hr=UnRegisterCLSIDInCategory(CLSID_SafeItem,                      CATID_SafeForInitializing);
    if (FAILED(hr))
      return hr;
    hr=UnRegisterCLSIDInCategory(CLSID_SafeItem,
                        CATID_SafeForScripting);
    if (FAILED(hr))
      return hr;
    return NOERROR;
}
