How to make a view that only shows content a user has not voted on I'm working on a project that asks a group of users with a specific role to vote on content produced by users with a different role.  

The group who votes is supposed to try and vote on each item, so I'm trying to make a view that will give them pages of the content.  

I would like the view to only show the content that they have not yet voted on, so when they have voted on all items, nothing is displayed in the view.
An effective solution to this problem can be found in http://drupal.org/node/513088.

As suggested by Cthos, one should first set up a "Relationship" in the view setting ("advanced" settings in Drupal 7), then use this relationship as a regular filter (no need for contextual filter here).The proposed procedure is:

Relationships
    Node: Votes
        "Require this relationship": no
        "Value type": No filtering
        "Vote tag": Normal vote
        "Restrict to current user": yes
Filters
    (Votes) Votes: Value
        "Relationship": use the one from above
        "Operator": "Is empty (NULL)"
