IE加载ocx时提示控件不安全的解决方法

之前编写的ocx控件在ie浏览器加载的时候，会出现一个提示。

这是因为ocx控件有一个ID，而这个ID注册后IE并没有认为它是安全的控件。

我们必须把这个控件注册为安全控件。

新建的mfc Activity项目有三个重要的类，xxApp，xxCtrl，xxPropPage三个类。

1.在xxApp类头文件添加如下函数声明：

HRESULT CreateComponentCategory(CATID catid, WCHAR* catDescription);// Helper function to register a CLSID as belonging to a component// categoryHRESULT RegisterCLSIDInCategory(REFCLSID clsid, CATID catid);// Helper function to unregister a CLSID as belonging to a component// categoryHRESULT UnRegisterCLSIDInCategory(REFCLSID clsid, CATID catid);

在xxApp类的实现文件添加如下：

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// categoryHRESULT 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;}// HRESULT UnRegisterCLSIDInCategory - Remove entries from the registryHRESULT 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;}

2.注册GUID

在xxApp.cpp定义两个GUID用来注册控件安全

const CATID CATID_SafeForScripting =    {0x7dd95801,0x9882,0x11cf,{0x9f,0xa9,0x00,0xaa,0x00,0x6c,0x42,0xc4}};const CATID CATID_SafeForInitializing =      {0x7dd95802,0x9882,0x11cf,{0x9f,0xa9,0x00,0xaa,0x00,0x6c,0x42,0xc4}};

同时在xxApp.cpp文件定义安全的CLSID

const CATID CLSID_SafeItem = {0x3ce7a2fd, 0x1ae9, 0x40b0, 0x83, 0xdb, 0x4a, 0x32, 0xce, 0xb2, 0xcf, 0x30};const GUID CDECL _tlid = { 0x59A67716, 0x53F0, 0x464A, { 0x9D, 0x35, 0x30, 0x24, 0x68, 0xBF, 0x1F, 0xCC } };const WORD _wVerMajor = 1;const WORD _wVerMinor = 0;

注意：CLSID_SafeItem其实就是xxCtrl.cpp里的这个值。

// 初始化类工厂和 guidIMPLEMENT_OLECREATE_EX(CActivePZCtrl, "ACTIVEPZ.ActivePZCtrl.1",0x3ce7a2fd, 0x1ae9, 0x40b0, 0x83, 0xdb, 0x4a, 0x32, 0xce, 0xb2, 0xcf, 0x30)

3.修改注册和反注册的代码

在xxApp.cpp文件的DllRegisterServer函数和DllUnRegisterServer函数。

STDAPI DllRegisterServer(void){/*AFX_MANAGE_STATE(_afxModuleAddrThis);if (!AfxOleRegisterTypeLib(AfxGetInstanceHandle(), _tlid))return ResultFromScode(SELFREG_E_TYPELIB);if (!COleObjectFactoryEx::UpdateRegistryAll(TRUE))return ResultFromScode(SELFREG_E_CLASS);return NOERROR;*///NEW下面是新的注册代码    AFX_MANAGE_STATE(_afxModuleAddrThis);    if (!AfxOleRegisterTypeLib(AfxGetInstanceHandle(), _tlid))      return ResultFromScode(SELFREG_E_TYPELIB);    if (!COleObjectFactoryEx::UpdateRegistryAll(TRUE))      return ResultFromScode(SELFREG_E_CLASS);    if (FAILED( CreateComponentCategory(         CATID_SafeForScripting,         L"Controls that are safely scriptable") ))       return ResultFromScode(SELFREG_E_CLASS);    if (FAILED( CreateComponentCategory(         CATID_SafeForInitializing,         L"Controls safely initializable from persistent data") ))       return ResultFromScode(SELFREG_E_CLASS);    if (FAILED( RegisterCLSIDInCategory(         CLSID_SafeItem, CATID_SafeForScripting) ))       return ResultFromScode(SELFREG_E_CLASS);    if (FAILED( RegisterCLSIDInCategory(         CLSID_SafeItem, CATID_SafeForInitializing) ))       return ResultFromScode(SELFREG_E_CLASS);    return NOERROR;}// DllUnregisterServer - 将项从系统注册表中移除STDAPI DllUnregisterServer(void){/*AFX_MANAGE_STATE(_afxModuleAddrThis);if (!AfxOleUnregisterTypeLib(_tlid, _wVerMajor, _wVerMinor))return ResultFromScode(SELFREG_E_TYPELIB);if (!COleObjectFactoryEx::UpdateRegistryAll(FALSE))return ResultFromScode(SELFREG_E_CLASS);return NOERROR;*///NEW下面是新的代码    HRESULT hr;    AFX_MANAGE_STATE(_afxModuleAddrThis);    // Remove entries from the registry.    hr=UnRegisterCLSIDInCategory(CLSID_SafeItem,        CATID_SafeForInitializing);    if (FAILED(hr))        return hr;    hr=UnRegisterCLSIDInCategory(CLSID_SafeItem,        CATID_SafeForScripting);    if (FAILED(hr))        return hr;    if (!AfxOleUnregisterTypeLib(_tlid, _wVerMajor, _wVerMinor))        return ResultFromScode(SELFREG_E_TYPELIB);    if (!COleObjectFactoryEx::UpdateRegistryAll(FALSE))        return ResultFromScode(SELFREG_E_CLASS);    return NOERROR;}

4.这个提示解决之后，因为IE设置的问题，还会出现如下提示：

可以在internet选项中设置
