Dear.

I want to replace the html contents in IE using COM module functions,
However,
The following functions doesn't work well.

Please check the following functions for replacing the html contents as
effect.

Best regards.

int CCommonInfo::PutStringTOIW(IWebBrowser2 *mWeb, CString strReplace)
{
IHTMLDocument2 *Document;
IDispatch *Dispatch;
HRESULT Result;
CString strHtml;
IHTMLElement *m_pBody;
IHTMLElement *lpParentElm;

IStream* pStream = NULL;
// HGLOBAL hHTMLText;

Result = mWeb->get_Document(&Dispatch);
if (FAILED(Result) || Dispatch == NULL)
return -1;

Result = Dispatch->QueryInterface(IID_IHTMLDocument2, (void **) &Document);
Dispatch->Release();
if (FAILED(Result))
return -1;

if (Document)
{
// Get the BODY object
Result = Document->get_body(&m_pBody);
Document->Release();
Document = NULL;

if (FAILED(Result) || !m_pBody)
return Result;

// Get the HTML text
BSTR bstrHTMLText = strReplace.AllocSysString();

// the parent of BODY is HTML
m_pBody->get_parentElement(&lpParentElm);
lpParentElm->put_outerHTML((BSTR)bstrHTMLText);

m_pBody->Release();
lpParentElm->Release();

lpParentElm = NULL;
m_pBody = NULL;
Document = NULL;
Dispatch = NULL;

::SysFreeString (bstrHTMLText);

}

return strOrg.GetLength() ;

}

Try to query IID_IPersistStreamInit interface by ihtmldocument.

The example is as follows:
