These are NOT variables. Are HTML codes to sp�cial caracters like "�"

In this case, the correct code is something like this:

IHTMLDocument2 * pDoc = NULL;
IHTMLELEMENT * pBodyElement = NULL;
HRESULT hr = pDoc->get_body( pBodyElement );
if( SUCCEED(hr) )
{
   IHTMLElement * pBody = NULL;
   hr = pBodyElem->QueryInterface( IID_IHTMLBodyElement, (void**)bBody );
}

You may have problems with the HTML you are viewing...
