OCX控件在web页面不能加载的问题

1，问题描述：写了个OCX，在本地静态html文件里加载，双击用IE打开，能够正常加载OCX控件，调用其方法也正常，把测试的html文件放入apache目录，通过IE 敲入localhost访问也正常，但是部署到服务器上，通过客户端PC访问服务器IP的方式，却不能加载OCX，其方法也调用不了。

2，问题解决，上网查了下，以及根据以往的对接经验，做如下设置：

1）在IE里把web服务的IP加入受信任站点：

2）还是在受信任站点的界面里设置“自定义级别”为“低”：

这样应该就能通过ip访问服务器页面时加载ocx控件了。

3，额外的解决：

后来查到ocx要实现安全接口：OCX控件在HTML中调用时提示：【SCRIPT3: 找不到成员。】

我试了下，添加了IObjectSafety接口后，不需要设置IE也可以正常加载OCX并调用其方法。

OCX控件在HTML中调用时提示：【SCRIPT3: 找不到成员。】

写了一个ocx控件，测试OK后，嵌入到HTML中使用，发现死活调取不了方法，很纳闷！

搜索了方法，说只要设置一下IE浏览器的权限即可：启用“对未标记为安全执行脚本的activex控件初始化并执行脚本”。

这个方法不是不行，而是要求每一个用户都去设置这个权限，显然不合适。

于是乎继续研究方法，终于找到了解决方案！

那就是：实现ActiveX组件的IObjectSafety接口，并且返回脚本安全。

具体来说，就是在h和cpp中加入以下代码：

1、OCXTestCtrl.h

// // ActiveX控件安全初始化：实现ISafeObject接口 // //ISafeObject 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); //ISafeObject

2、OCXTestCtrl.cpp

// // ActiveX控件安全初始化：实现ISafeObject接口 // // Interface map for IObjectSafety BEGIN_INTERFACE_MAP( COCXTestCtrl, COleControl ) INTERFACE_PART(COCXTestCtrl, IID_IObjectSafety, ObjSafe) END_INTERFACE_MAP() // IObjectSafety member functions // Delegate AddRef, Release, QueryInterface ULONG FAR EXPORT COCXTestCtrl::XObjSafe::AddRef() { METHOD_PROLOGUE(COCXTestCtrl, ObjSafe) return pThis->ExternalAddRef(); } ULONG FAR EXPORT COCXTestCtrl::XObjSafe::Release() { METHOD_PROLOGUE(COCXTestCtrl, ObjSafe) return pThis->ExternalRelease(); } HRESULT FAR EXPORT COCXTestCtrl::XObjSafe::QueryInterface( REFIID iid, void FAR* FAR* ppvObj) { METHOD_PROLOGUE(COCXTestCtrl, 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 COCXTestCtrl::XObjSafe::GetInterfaceSafetyOptions( /* [in] */ REFIID riid, /* [out] */ DWORD __RPC_FAR *pdwSupportedOptions, /* [out] */ DWORD __RPC_FAR *pdwEnabledOptions) { METHOD_PROLOGUE(COCXTestCtrl, 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 COCXTestCtrl::XObjSafe::SetInterfaceSafetyOptions( /* [in] */ REFIID riid, /* [in] */ DWORD dwOptionSetMask, /* [in] */ DWORD dwEnabledOptions) { METHOD_PROLOGUE(COCXTestCtrl, 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); } //
