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
// category
HRESULT RegisterCLSIDInCategory(REFCLSID clsid, CATID catid);
// Helper function to unregister a CLSID as belonging to a component
// category
HRESULT 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
// 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;
}
// HRESULT UnRegisterCLSIDInCategory - Remove entries from the registry
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;

}

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 guid

IMPLEMENT_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
