Geotargeting, Help with this coding

[SouthernTn]

Need a bit of help with this coding.. How can I implement this into vb so that I can get it working...

PHP Code:

<? 
$ip = $_SERVER['REMOTE_ADDR']; 
include("geoip.inc");  $gi = geoip_open(dirname(__FILE__)."/GeoIP.dat",GEOIP_STANDARD); 
 if (geoip_country_code_by_addr($gi, $ip)!= US) { 
 include('adsense.php'); 
 } 
else { 
include('ypn.php'); 
} 
 geoip_close($gi); 
 ?>
