still have some problem with Implement IE browser

Hi all,
    I used to post to ask about Implement IE browser
http://www.experts-exchange.com/jsp/qManageQuestion.jsp?ta=mfc&qid=20310762

. I got some useful solution to use IDocHostUIHandler::GetHostInfo .And I found useful help
from microsoft http://msdn.microsoft.com/Downloads/samples/Internet/browser/driller/sample.asp.
So I can prevent scroll bars or change their appearance and the others. But I still have some problem to disable javascript. I try to changed at IDocHostUIHandler::GetHostInfo   like this

HRESULT FAR EXPORT  CCustomControlSite::XDocHostUIHandler::GetHostInfo( DOCHOSTUIINFO* pInfo )
{


 WCHAR* szCSS = L"BODY {background-color:#ffcccc}";
   WCHAR* szNS = L"IE;MyTags;MyTags2='www.microsoft.com'";
   OLECHAR* pCSSBuffer = (OLECHAR*)CoTaskMemAlloc((wcslen(szCSS) + 1) * sizeof(OLECHAR));
   OLECHAR* pNSBuffer = (OLECHAR*)CoTaskMemAlloc((wcslen(szNS) + 1) * sizeof(OLECHAR));
   wcscpy(pCSSBuffer, szCSS);
   wcscpy(pNSBuffer, szNS);

   pInfo->cbSize = sizeof(DOCHOSTUIINFO);
   pInfo->dwFlags = DOCHOSTUIFLAG_NO3DBORDER | DOCHOSTUIFLAG_DISABLE_SCRIPT_INACTIVE;
   pInfo->dwDoubleClick = DOCHOSTUIDBLCLK_DEFAULT;
   pInfo->pchHostCss = pCSSBuffer;
   pInfo->pchHostNS = pNSBuffer;
    return S_OK;
}
But it doesn't disable javascript . Does anyone have an idea  to help me.?

Hi!
DOCHOSTUIFLAG_DISABLE_SCRIPT_INACTIVE flag disables JavaScript only during page loading.
Do you want diasable all scripts execution in the page?

Hi!
You have to implement Invoke member in the your host

STDMETHODIMP CCustomControlSite::Invoke(DISPID dispidMember, REFIID riid,
                               LCID lcid, WORD wFlags,
                               DISPPARAMS* pDispParams,
                               VARIANT* pvarResult,
                               EXCEPINFO* pExcepInfo,
                               UINT* puArgErr)
{
    switch (dispidMember)
    {
    case DISPID_AMBIENT_DLCONTROL:
        pvarResult->vt = VT_I4;
        pvarResult->lVal = DLCTL_DLIMAGES | DLCTL_VIDEOS | DLCTL_NO_SCRIPTS; //<< here!
        break;

    default:
        return DISP_E_MEMBERNOTFOUND;
    }

    return S_OK;
}

I put your code to my program but it doesn't work.
(javascript still work)

 This is my code  that I put into idispimp.cpp
STDMETHODIMP CImpIDispatch::Invoke(
            /* [in] */ DISPID dispIdMember,
            /* [in] */ REFIID /*riid*/,
            /* [in] */ LCID /*lcid*/,
            /* [in] */ WORD wFlags,
            /* [out][in] */ DISPPARAMS* pDispParams,
            /* [out] */ VARIANT* pVarResult,
            /* [out] */ EXCEPINFO* /*pExcepInfo*/,
            /* [out] */ UINT* puArgErr)
{

     // For this sample we only support a Property Get on DISPID_Extend
     // returning a BSTR with "Wibble" as the value
     if ( dispIdMember == DISPID_Extend )
     {
          if ( wFlags & DISPATCH_PROPERTYGET )
          {
               if ( pVarResult != NULL )
               {
                    WCHAR buff[10]=L"Wibble";
                    BSTR bstrRet = SysAllocString( buff );
                    VariantInit(pVarResult);
                    V_VT(pVarResult)=VT_BSTR;
                    V_BSTR(pVarResult) = bstrRet;
               }
          }
     }
     if ( dispIdMember == DISPID_AMBIENT_DLCONTROL )
     {
       pVarResult->vt = VT_I4;
       pVarResult->lVal = DLCTL_DLIMAGES | DLCTL_VIDEOS | DLCTL_NO_SCRIPTS; //<< here!
   
     }

     return S_OK;
}

it's file from microsoft sample (driller). I do something wrong?   and do you have some sample ?

Hi!  
   It 's work !! .I'm really appreciate. Would you mind to suggest  me how I can get more information about it ? I saw some information in msdn about web browser customization. But I don't understand how I can implement it.
 I'm beginning  in  ATL , COM .

Thank for you kind .

Hi!
You have to read MSDN part WEB workshop also MSDN search tool can help but in this case defining accurate search phrase is main problem :-)
GOOD LUCK!
