I remember when i used to work with VB.NET. Hashing is headache. I see you are trying to md5 hash crypcode. In php its simple. Dont know why Microsoft languages long it out. They must have their reasons. Believe it or not in php its one line.

$crypcode = date("Y") + ($seed + date("z"));
$key = md5($crypcode);
return $key;
