Vista - Getting Interface ID back from a COM object?

Is there a simple way to get the interface ID back from a COM object? It
doesn't appear to be a distinct entity, but the GUID appended to the
System.__ComObject type in object names appears to be an interface ID. The
only way I can get it right now is to use the following fairly ugly
string-hacking technique:

$xh = New-Object -ComObject Microsoft.XmlHttp
$typenames = $xh.PSObject.Typenames;
for($i = 0; $i -lt $typenames.Count)
{
if($typenames[$i].Contains("#"))
{
$start = $typenames[$i].IndexOf("#") + 1;
$typenames[$i].Substring($start);
}
}


Obviously, this is less than desirable, since I'm doing work to separate an
item that is apparently available as a distinct string already.

What you are doing it the only way as far as I recall. We do not expose it
as an separate property; only as part of the typename
