Disable the admin bar

by

I have the WP3.4 and I would like to disable the admin bar. I have tried to do that with many ways, but the admin bar do not display. Is possible to do on this version of WP (3.4) or i make a mistake in the code?
Below are the ways that I’ve tried.
Thanks in advance.
The 1st : 

function my_function_admin_bar(){
            return false;
        }
        add_filter( 'show_admin_bar' , 'my_function_admin_bar');

The 2nd :

add_action( 'init', 'disable_admin_bar', 1 );
function disable_admin_bar() {
    add_filter( 'show_admin_bar', '__return_false' );

The 3rd

    <?php
if (!function_exists('disableAdminBar')) {

    function disableAdminBar(){

    remove_action( 'admin_footer', 'wp_admin_bar_render', 1000 ); // for the admin page
    remove_action( 'wp_footer', 'wp_admin_bar_render', 1000 ); // for the front end

    function remove_admin_bar_style_backend() {  // css override for the admin page
      echo '<style>body.admin-bar #wpcontent, body.admin-bar #adminmenu { padding-top: 0px !important; }</style>';
    }

    add_filter('admin_head','remove_admin_bar_style_backend');

    function remove_admin_bar_style_frontend() { // css override for the frontend
      echo '<style type="text/css" media="screen">
      html { margin-top: 0px !important; }
      * html body { margin-top: 0px !important; }
      </style>';
    }

    add_filter('wp_head','remove_admin_bar_style_frontend', 99);

  }

}

// add_filter('admin_head','remove_admin_bar_style_backend'); // Original version
add_action('init','disableAdminBar'); // New version


    ?>

You need to specify the order or number which signifies when the Hook gets fired. In this case I beleive it’s 0 and the filter is: wp_admin_bar_render. The action to remove the function I believe is:

remove_action( 'in_admin_header', 'wp_admin_bar_render', 0);

The Function Reference:

Function Reference/remove action

And here it is in the core file:
