[wp-hackers] loading css only on page where plugin is used

[Aaron D. Campbell]

I mean using the WP_Query class to create a query that is NOT stored in 
the $wp_query global.  For example:

$queryArgs = array(
    'nopaging'        => true,
    'post_type'        => 'any',
    'post_status'    => 'draft,pending,future,publish'
);
$myQuery = new WP_Query($queryArgs);
if ($myQuery->have_posts()) {
    while ($myQuery->have_posts()) {
        $post = $myQuery->next_post();
        // Do something with $post
    }
}
