Display custom post using ID

Question

In my theme, I have a custom post type called sliders. Here the user is allowed to upload images in a meta-box. So, the images are saved as meta data in wp_post_meta table.

Now what I want to do is, displaying a slider using its ID.

I did like following but 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 even errors. Anyway, If I used the_title() instead of the_post(), it shows the title of the slider fine. Same for the the_author() It shows the author without error.

Why is this weird ?

EDIT: deleted incorrect information

I see what you are missing now. Without knowing the specifics, I tried to point you in the right direction with this:

$my_query = new WP_Query('post_type=sliders&p=411');

if( $my_query->have_posts() ) {
    while ( $my_query->have_posts() ) : $my_query->the_post();

        // Get the specific meta data for the current post
        $saved_slider_meta = get_post_meta( get_the_ID(), 'slider_meta_key' );

        // Echo the data
        echo $saved_slider_meta;

    endwhile;

    // Restore original post data if there are other loops
    wp_reset_post_data();
}

Here is more information about WP_Query.

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

    $slider_imgs = get_post_meta( get_the_ID(), 'slider_meta_key' );

    foreach($slider_imgs as $slider_img)
    {
       echo '<img src="'.$saved_slider_meta.'">';
    }
  endwhile;
  wp_reset_post_data();
}
