Answer 1

A very basic example,

$args = array(  'post_type' => 'post', 'posts_per_page' => -1 );
$query= new WP_Query($args);
while ( $query->have_posts() ) : $query->the_post();

    the_content(); //example, use whatever template functions you like...

endwhile;
wp_reset_postdata(); //reset Post Data
wp_reset_query(); //destroy query incase of using multiple queries on same page

Important:

Note, that this is probably an inefficient way to achieve what you want because if your post_type contains many posts it may impede your sites performance because the parameter posts_per_page => -1 will load all posts from the given posts type within your slider.

To improve performance you should restrict your slider content to a special category and use the category parameter 'cat' => $id where $id is in integer value 1, 2, 3 etc.

Better still, I'd personally confine my slides to a custom post type and add 'post_type' => 'slider_posts' but this assumes you have registered a custom post type before hand.

Its important that you read http://codex.wordpress.org/Class_Reference/WP_Query which contains a great deal of information surrounding the various parameters you can use with WP_Query to achieve custom control of what data you retrieve.

If you're loading these as slides, you're probably looking at this problem wrong. You don't need to infinitely loop through the posts with PHP, you just need to present them once to the slider and makes sure it can manage repeating. What slider are you using?
