hi,

i came across these links information:

i haven't used webclient class myself, decided give try. following code works me:

$url = "http://www.storagecraft.com/software_update.php" $webclient = new-object system.net.webclient $html = $webclient.downloadstring("$url")  $versioncheck = (($html.substring($html.lastindexof("shadowprotect installers</th>") + 29, 20)).replace("<th>","")).replace("</th>","").trim() $versioncheck

might break if page changes in future, seems fine now.
