MFC activex控件在IE中弹出安全警告的解决办法

  1.要加一个头文件:
         #include <objsafe.h>

2.在控件头文件中加入:

   DECLARE_INTERFACE_MAP()

   BEGIN_INTERFACE_PART(ObjectSafety, IObjectSafety)
       STDMETHOD(GetInterfaceSafetyOptions)(REFIID riid, DWORD __RPC_FAR *pdwSupportedOptions, DWORD __RPC_FAR *pdwEnabledOptions);
       STDMETHOD(SetInterfaceSafetyOptions)(REFIID riid, DWORD dwOptionSetMask, DWORD dwEnabledOptions);
   END_INTERFACE_PART(ObjectSafety)

3.在控件的CPP文件中加入：

BEGIN_INTERFACE_MAP(CVP2PCtrl, COleControl)
INTERFACE_PART(CVP2PCtrl, IID_IObjectSafety, ObjectSafety)
END_INTERFACE_MAP()
// Implementation of IObjectSafety
STDMETHODIMP CVP2PCtrl::XObjectSafety::GetInterfaceSafetyOptions(
   REFIID riid,
   DWORD __RPC_FAR *pdwSupportedOptions,
   DWORD __RPC_FAR *pdwEnabledOptions)
{
METHOD_PROLOGUE_EX(CVP2PCtrl, ObjectSafety)

if (!pdwSupportedOptions || !pdwEnabledOptions)
{
return E_POINTER;
}

*pdwSupportedOptions = INTERFACESAFE_FOR_UNTRUSTED_CALLER | INTERFACESAFE_FOR_UNTRUSTED_DATA;
*pdwEnabledOptions = 0;

if (NULL == pThis->GetInterface(&riid))
{
TRACE("Requested interface is not supported.\n");
return E_NOINTERFACE;
}

// What interface is being checked out anyhow?
OLECHAR szGUID[39];
int i = StringFromGUID2(riid, szGUID, 39);

if (riid == IID_IDispatch)
{
  // Client wants to know if object is safe for scripting
  *pdwEnabledOptions = INTERFACESAFE_FOR_UNTRUSTED_CALLER;
  return S_OK;
}
else if (riid == IID_IPersistPropertyBag
    || riid == IID_IPersistStreamInit
    || riid == IID_IPersistStorage
    || riid == IID_IPersistMemory)
{
  // Those are the persistence interfaces COleControl derived controls support
  // as indicated in AFXCTL.H
  // Client wants to know if object is safe for initializing from persistent data
  *pdwEnabledOptions = INTERFACESAFE_FOR_UNTRUSTED_DATA;
  return S_OK;
}
else
{
  // Find out what interface this is, and decide what options to enable
  TRACE("We didn't account for the safety of this interface, and it's one we support...\n");
  return E_NOINTERFACE;
}
}

STDMETHODIMP CVP2PCtrl::XObjectSafety::SetInterfaceSafetyOptions(
  REFIID riid,
  DWORD dwOptionSetMask,
  DWORD dwEnabledOptions)
{
METHOD_PROLOGUE_EX(CVP2PCtrl, ObjectSafety)

OLECHAR szGUID[39];
// What is this interface anyway?
// We can do a quick lookup in the registry under HKEY_CLASSES_ROOT\Interface
int i = StringFromGUID2(riid, szGUID, 39);

if (0 == dwOptionSetMask && 0 == dwEnabledOptions)
{
  // the control certainly supports NO requests through the specified interface
  // so it's safe to return S_OK even if the interface isn't supported.
  return S_OK;
}

// Do we support the specified interface?
if (NULL == pThis->GetInterface(&riid))
{
TRACE1("%s is not support.\n", szGUID);
return E_FAIL;
}

if (riid == IID_IDispatch)
{
  TRACE("Client asking if it's safe to call through IDispatch.\n");
  TRACE("In other words, is the control safe for scripting?\n");
  if (INTERFACESAFE_FOR_UNTRUSTED_CALLER == dwOptionSetMask && INTERFACESAFE_FOR_UNTRUSTED_CALLER == dwEnabledOptions)
  {
   return S_OK;
  }
  else
  {
   return E_FAIL;
  }
}
else if (riid == IID_IPersistPropertyBag
    || riid == IID_IPersistStreamInit
    || riid == IID_IPersistStorage
    || riid == IID_IPersistMemory)
{
  TRACE("Client asking if it's safe to call through IPersist*.\n");
  TRACE("In other words, is the control safe for initializing from persistent data?\n");

//OK！不会再弹出那个“与ActiveX控件交互不安全“的对话框了~~~

//其中CVP2PCtrl全部要换成你的控件的类名~
