update forum data from external application

[asandhanam]

Right. That was bad decision. I didn't have permissions to upload files to the root. I had to wait for my sys admin to grant permissions..i thought i'll try uploading it to includes folder & test in the mean while..
If i were to put it in root & test, what other class files will i have to include to get this to work. All i want to be able to do is update a new field that i added to the forum table, with the datamanager? Thanks a lot for your time.
BTW i've only tried to include the global.php thats in the root in my prev script. (include './global.php')? I just copied that part from the forum.php in admincp.

Thanks for your help so far. I moved it to the root & it included the core class files..It works till initiating the datamanager object. But saving part doesn't work yet. What other files need to be included to get it working?

$forumdm =& datamanager_init('Forum', $vbulletin, ERRTYPE_CP);

echo "initiated";

$foruminfo = fetch_foruminfo($forum_num);

$forumdm->set_existing($foruminfo);
//$forumdm->set('sponsored', $sponsored);
$forumdm->set('title_clean', 'new title');
//unset($forumdm);


if ($forumdm->save())
echo "saved";
else
echo "error";

Update: Got it to work. For anyone who wants to know:

This file is placed in the root.
