MFC開發的OCX控件即使使用了簽名。在IE中運行是也會提示“頁面中的OCX的交互是不安全的。。。。”。解決辦法有兩種
方案1：修改IE的設置：
方案2：標記控件為腳本安全的
在工程中增加頭文件 cathelp.h
#ifndef _CATHELP_H_
#define _CATHELP_H_
#include <comcat.h>
HRESULT CreateComponentCategory(CATID catid, WCHAR* catDescription);
HRESULT RegisterCLSIDInCategory(REFCLSID clsid, CATID catid);
HRESULT UnRegisterCLSIDInCategory(REFCLSID clsid, CATID catid);
#endif
增加cathelp.cpp
#include "cathelp.h"
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';
if(pcr)
{
hr = pcr->RegisterCategories(1, &catinfo);
pcr->Release();
}
return hr;
}
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(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;
}
修改 ocx的 DllRegisterServer 方法
#include "cathelp.h"
#include <objsafe.h>//for CATID_SafeForInitializing
#include "SafeocxtestCtl.h"
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);
// 注冊腳本安全
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(
CSafeocxtestCtrl::guid, CATID_SafeForScripting) ))
return ResultFromScode(SELFREG_E_CLASS);
if (FAILED( RegisterCLSIDInCategory(
CSafeocxtestCtrl::guid, CATID_SafeForInitializing) ))
return ResultFromScode(SELFREG_E_CLASS);
return NOERROR;
}
/////////////////////////////////////////////////////////////////////////////
// DllUnregisterServer - Removes entries from the system registry
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);
// 控件安全反初始化
UnRegisterCLSIDInCategory( CSafeocxtestCtrl::guid, CATID_SafeForScripting);
UnRegisterCLSIDInCategory( CSafeocxtestCtrl::guid, CATID_SafeForInitializing);
return NOERROR;
}
編譯注冊就OK了。
如果要查看ocx是否是腳本安全的。在注冊表HKEY_CLASSES_ROOT\CLSID\OCX的clsid\Implemented Categories\ 下看一下有沒有“{7DD95801-9882-11CF-9FA9-00AA006C42C4}” 和“{7DD95802-9882-11CF-9FA9-00AA006C42C4}”
下圖就是腳本安全的：
