vb.org Archive - How can i change BitField Values

I am creating a Custom Product for vBulletin (my first time) and i am picking up the format etc. from this site slowly.
Now, i am stuck on Bitfield xml file.

i have created a bitfield_product.xml file. vBulletin is picking up this file and showing the options, and its working nicely. Following is my BitField file

Code:

<?xml version="1.0" encoding="ISO-8859-1"?>



<bitfields product="_vbhostreview">

        <bitfielddefs>

                <group name="ugp">

                        <group name="vbhr_permission">

                                <bitfield name="vbhr_canapprovehost" group="vbhr_permission" phrase="vbhr_canapprovehost" install="5,6">1</bitfield>

                                <bitfield name="vbhr_candeletehost" group="vbhr_permission" phrase="vbhr_candeletehost"  install="5,6">1</bitfield>

                        </group>

                </group>

        </bitfielddefs>

</bitfields>

Install/Uninstall Code in product file

Code:

<installcode>

$db->query("

                ALTER TABLE " . TABLE_PREFIX ."usergroup ADD vbhr_permission INT( 10 ) UNSIGNED DEFAULT '0' NOT NULL "

        );

                if (is_newer_version('3.5.1', $vbulletin->options['templateversion']))

                {

                        // Rebuild Bitfields

                        // Do this for vBulletin < 3.5.1 *ONLY*; later versions rebuild

                        // automatically and calling the builder in install code causes

                        // the bitfields NOT to be rebuild correctly

                        require_once(DIR . '/includes/class_bitfield_builder.php');

                        vB_Bitfield_Builder::save($db);

                        build_forum_permissions();

                }

]]></installcode>

        <uninstallcode><![CDATA[

        $db->query("

                ALTER TABLE " . TABLE_PREFIX ."usergroup drop column vbhr_permission"

        );

        

                if (is_newer_version('3.5.1', $vbulletin->options['templateversion']))

                {

                        // Rebuild Bitfields

                        // Do this for vBulletin < 3.5.1 *ONLY*; later versions rebuild

                        // automatically and calling the builder in install code causes

                        // the bitfields NOT to be rebuild correctly

                        require_once(DIR . '/includes/class_bitfield_builder.php');

                        vB_Bitfield_Builder::save($db);

                        build_forum_permissions();

                }

]]></uninstallcode>

I have 2 questions:
1) How do i make the default value to Yes (right now its making it No)
2) I see there are some HELP files with other settings (? beside each setting). How can i provide help for my custom permissions??

Thanks in advance.

I changed one line, not sure if its correct way to do it, buts it seems to be working

i changed
$db->query("ALTER TABLE " . TABLE_PREFIX ."usergroup ADD vbhr_permission INT( 10 ) UNSIGNED DEFAULT '0' NOT NULL ");

TO
$db->query("ALTER TABLE " . TABLE_PREFIX ."usergroup ADD vbhr_permission INT( 10 ) UNSIGNED DEFAULT '3' NOT NULL ");

Having default value of 3, it turns Both options on.

But, then if i change some options later on, it doesn't seem to work?

ANyone Please??
or give me a link to some tutorial
