本文共 9310 字，大约阅读时间需要 31 分钟。

在xxxCtrl.h（xxx为项目名）头文件中的 #pragma once的下一行添加

//-------添加---------------

//取消ie的安全提示

#include "objsafe.h"

//---------添加完----------------------------

并在头文件类中的声明部分声明（和CxxxCtrl()构造函数同一个地方）

//----------增加  取消ie的安全提示-----=----    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);    //---------添加完----------------------------

在 CPP实现文件

BOOL Cmax200Ctrl::Cmax200CtrlFactory::UpdateRegistry(BOOL bRegister)函数后面添加如下

注意下面的代码要替换Cmax200Ctrl到你自己的类名

//--------添加-------------------//取消ie的安全提示/ // Interface map for IObjectSafety	BEGIN_INTERFACE_MAP( Cmax200Ctrl, COleControl ) 		INTERFACE_PART(Cmax200Ctrl, IID_IObjectSafety, ObjSafe) 	END_INTERFACE_MAP()/ // IObjectSafety member functions// Delegate AddRef, Release, QueryInterfaceULONG FAR EXPORT Cmax200Ctrl::XObjSafe::AddRef() { 	METHOD_PROLOGUE(Cmax200Ctrl, ObjSafe) 		return pThis->ExternalAddRef(); }ULONG FAR EXPORT Cmax200Ctrl::XObjSafe::Release() { 	METHOD_PROLOGUE(Cmax200Ctrl, ObjSafe) 		return pThis->ExternalRelease(); }HRESULT FAR EXPORT Cmax200Ctrl::XObjSafe::QueryInterface( 	REFIID iid, void FAR* FAR* ppvObj) { 	METHOD_PROLOGUE(Cmax200Ctrl, 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.

Implement the CreateComponentCategory and RegisterCLSIDInCategory helper functions by adding the following cathelp.h and cathelp.cpp files to your project.

Cathelp.h

#include "comcat.h"      // Helper function to create a component category and associated      // description      HRESULT CreateComponentCategory(CATID catid, WCHAR* catDescription);      // Helper function to register a CLSID as belonging to a component      // category      HRESULT RegisterCLSIDInCategory(REFCLSID clsid, CATID catid);

Cathelp.cpp

#include "comcat.h"      // Helper function to create a component category and associated      // description      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;      }

Modify the DllRegisterServer to mark the control as safe. Locate the implementation of DllRegisterServer in a .cpp file in your project. You will need to add several things to this .cpp file. Include the file that implements CreateComponentCategory and RegisterCLSIDInCategory:

#include "CatHelp.h"

Define the GUID associated with the safety component categories:

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}};

Define the GUID associated with your control. For simplicity, you can borrow the GUID from theIMPLEMENT_OLECREATE_EX macro in the main .cpp file for the control. Adjust the format slightly so that it looks like the following:

const GUID CDECL BASED_CODE _ctlid =      { 0x43bd9e45, 0x328f, 0x11d0,              { 0xa6, 0xb9, 0x0, 0xaa, 0x0, 0xa7, 0xf, 0xc2 } };

To mark your control as both Safe for Scripting and Initialization, modify the DllRegisterServer function as follows:

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);          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(                  _ctlid, CATID_SafeForScripting) ))                return ResultFromScode(SELFREG_E_CLASS);          if (FAILED( RegisterCLSIDInCategory(                  _ctlid, CATID_SafeForInitializing) ))                return ResultFromScode(SELFREG_E_CLASS);          return NOERROR;      }

You would not normally modify the DllUnregisterServer function for these two reasons:

You would not want to remove a component category because other controls may be using it.

Although there is an UnRegisterCLSIDInCategory function defined, by default DllUnregisterServer removes the control's entry from the registry entirely. Therefore, removing the category from the control's registration is of little use.===============================================
