            小步慢跑

             

            標記ocx控件為腳本安全

            MFC開發(fā)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。。。?!薄=鉀Q辦法有兩種

            方案1:修改IE的設(shè)置:

            image

            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)
            
            {

                hr = CoCreateInstance(CLSID_StdComponentCategoriesMgr,

            	// Only copy the first 127 characters if it is

            修改 ocx的 DllRegisterServer 方法

            #include "cathelp.h"

            	if (!AfxOleRegisterTypeLib(AfxGetInstanceHandle(), _tlid))
            
            		return ResultFromScode(SELFREG_E_TYPELIB);
            
            	if (!COleObjectFactoryEx::UpdateRegistryAll(TRUE))

            	// 注冊腳本安全
            
            	if( FAILED( CreateComponentCategory(CATID_SafeForScripting, L"Controls that are safely scriptable") ) )

            		CSafeocxtestCtrl::guid, CATID_SafeForScripting) ))
            
            		return ResultFromScode(SELFREG_E_CLASS);

                            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:
