wordpress - Display custom post using ID -

in theme, have custom post type called sliders. here user allowed upload images in meta-box. so, images saved meta data in wp_post_meta table.

now want is, displaying slider using id.

i did following no result

$my_query = new wp_query('post_type=sliders&p=411');  if( $my_query->have_posts() ) {    while ($my_query->have_posts()) : $my_query->the_post();     the_post();  endwhile; } 

this doesn't display anything. no errors. anyway, if used the_title() instead of the_post(), shows title of slider fine. same the_author() shows author without error.

why weird ?

according codex the_post(); :

the_post(); iterate post index in loop. retrieves next post, sets post, sets 'in loop' property true. this function not return values.

example how use function:

<?php if ( have_posts() ) {     while ( have_posts() ) {          the_post();          he_title();          the_content();      } } ?> 

you didn't explain question. anyway display metabox use api function

echo get_post_meta( $id, 'metabox_name', true );
