在代码中实现IObjectSafety接口,以去除IE对代码未标识安全的提示
在“<工程名>Ctrl.h”中
引入头文件
- #include <ObjSafe.h>
在“DECLARE_DYNCREATE(C<工程名>Ctrl)”语句下面添加
- DECLARE_INTERFACE_MAP()
- BEGIN_INTERFACE_PART(ObjSafe, IObjectSafety)
- STDMETHOD_(HRESULT, GetInterfaceSafetyOptions) (
- /* [in] */ REFIID riid,
- /* [out] */ DWORD __RPC_FAR *pdwSupportedOptions,
- /* [out] */ DWORD __RPC_FAR *pdwEnabledOptions
- );
- STDMETHOD_(HRESULT, SetInterfaceSafetyOptions) (
- /* [in] */ REFIID riid,
- /* [in] */ DWORD dwOptionSetMask,
- /* [in] */ DWORD dwEnabledOptions
- );
- END_INTERFACE_PART(ObjSafe);
在“<工程名>Ctrl.cpp”中的UpdateRegistry方法后加入
- /
- // Interface map for IObjectSafety
- BEGIN_INTERFACE_MAP( C<工程名>Ctrl, COleControl )
- INTERFACE_PART(C<工程名>Ctrl, IID_IObjectSafety, ObjSafe)
- END_INTERFACE_MAP()
- /
- // IObjectSafety member functions
- // Delegate AddRef, Release, QueryInterface
- ULONG FAR EXPORT C<工程名>Ctrl::XObjSafe::AddRef()
- {
- METHOD_PROLOGUE(C<工程名>Ctrl, ObjSafe)
- return pThis->ExternalAddRef();
- }
- ULONG FAR EXPORT C<工程名>Ctrl::XObjSafe::Release()
- {
- METHOD_PROLOGUE(C<工程名>Ctrl, ObjSafe)
- return pThis->ExternalRelease();
- }
- HRESULT FAR EXPORT C<工程名>Ctrl::XObjSafe::QueryInterface(
- REFIID iid, void FAR* FAR* ppvObj)
- {
- METHOD_PROLOGUE(C<工程名>Ctrl, ObjSafe)
- return (HRESULT)pThis->ExternalQueryInterface(&iid, ppvObj);
- }
- const DWORD dwSupportedBits =
- INTERFACESAFE_FOR_UNTRUSTED_CALLER |
- INTERFACESAFE_FOR_UNTRUSTED_DATA;
- const DWORD dwNotSupportedBits = ~ dwSupportedBits;
- /
- // CStopLiteCtrl::XObjSafe::GetInterfaceSafetyOptions
- // Allows container to query what interfaces are safe for what. We're
- // optimizing significantly by ignoring which interface the caller is
- // asking for.
- HRESULT STDMETHODCALLTYPE
- C<工程名>Ctrl::XObjSafe::GetInterfaceSafetyOptions(
- /* [in] */ REFIID riid,
- /* [out] */ DWORD __RPC_FAR *pdwSupportedOptions,
- /* [out] */ DWORD __RPC_FAR *pdwEnabledOptions)
- {
- METHOD_PROLOGUE(C<工程名>Ctrl, ObjSafe)
- HRESULT retval = ResultFromScode(S_OK);
- // does interface exist?
- IUnknown FAR* punkInterface;
- retval = pThis->ExternalQueryInterface(&riid,
- (void * *)&punkInterface);
- if (retval != E_NOINTERFACE) { // interface exists
- punkInterface->Release(); // release it--just checking!
- }
- // we support both kinds of safety and have always both set,
- // regardless of interface
- *pdwSupportedOptions = *pdwEnabledOptions = dwSupportedBits;
- return retval; // E_NOINTERFACE if QI failed
- }
- /
- // CStopLiteCtrl::XObjSafe::SetInterfaceSafetyOptions
- // Since we're always safe, this is a no-brainer--but we do check to make
- // sure the interface requested exists and that the options we're asked to
- // set exist and are set on (we don't support unsafe mode).
- HRESULT STDMETHODCALLTYPE
- C<工程名>Ctrl::XObjSafe::SetInterfaceSafetyOptions(
- /* [in] */ REFIID riid,
- /* [in] */ DWORD dwOptionSetMask,
- /* [in] */ DWORD dwEnabledOptions)
- {
- METHOD_PROLOGUE(C<工程名>Ctrl, ObjSafe)
- // does interface exist?
- IUnknown FAR* punkInterface;
- pThis->ExternalQueryInterface(&riid, (void * *)&punkInterface);
- if (punkInterface) { // interface exists
- punkInterface->Release(); // release it--just checking!
- }
- else { // interface doesn't exist
- return ResultFromScode(E_NOINTERFACE);
- }
- // can't set bits we don't support
- if (dwOptionSetMask & dwNotSupportedBits) {
- return ResultFromScode(E_FAIL);
- }
- // can't set bits we do support to zero
- dwEnabledOptions &= dwSupportedBits;
- // (we already know there are no extra bits in mask )
- if ((dwOptionSetMask & dwEnabledOptions) !=
- dwOptionSetMask) {
- return ResultFromScode(E_FAIL);
- }
- // don't need to change anything since we're always safe
- return ResultFromScode(S_OK);
- }
说明
- 本solution中建了一个ActiveX控件,与3个测试容器分别为C#、C++、HTML,见截图:
- vs2012中方法与属性在MyMFCActiveXControlLib/_DMyMFCActiveXControl右击添加,事件则在CMyMFCActiveXControlCtrl中添加
- vs2012中在属性页中添加新控件并为其关联属性时无“Optional property name”,必须在DoDataExchange中用DDP_Text手动关联控件变量
- // CMyMFCActiveXControlPropPage::DoDataExchange - 在页和属性间移动数据
- void CMyMFCActiveXControlPropPage::DoDataExchange(CDataExchange* pDX)
- {
- DDP_Text(pDX, IDC_EDIT_INTERVAL, m_updateInterval,L"Interval");
- DDX_Text(pDX, IDC_EDIT_INTERVAL, m_updateInterval);
- DDP_PostProcessing(pDX);
- }
- 在ActiveX控件的工程属性页设置使用IE进行调试后,直接按F5进行调试的话由于IE新建进程打开此HTML页而使得无法进入断点,应该为VS附加至目标iexplorer进程
- c#容器工程测试运行时抛“未处理COMException”,生成的目标平台设为“x86”即可
- 在本地上打开html页进行测试时,ActiveX会自动注册
