uses 
  ActiveX; 
 
procedure WB_LoadHTML(WebBrowser: TWebBrowser; HTMLCode: string); 
var 
  sl: TStringList; 
  ms: TMemoryStream; 
begin 
  WebBrowser.Navigate('about:blank'); 
  while WebBrowser.ReadyState < READYSTATE_INTERACTIVE do 
   Application.ProcessMessages; 
 
  if Assigned(WebBrowser.Document) then 
  begin 
    sl := TStringList.Create; 
    try 
      ms := TMemoryStream.Create; 
      try 
        sl.Text := HTMLCode; 
        sl.SaveToStream(ms); 
        ms.Seek(0, 0); 
        (WebBrowser.Document as IPersistStreamInit).Load(TStreamAdapter.Create(ms)); 
      finally 
        ms.Free; 
      end; 
    finally 
      sl.Free; 
    end; 
  end;
