This would be the core of it if you're using Apache::ASP or Perlscript on IIS. You still need to put your table in the %vals hash (using DBI) and also do formatting and print the option names by each combo box. Doing it with CGI.pm should also be easy, so take a look at that module's documentation if you don't have ASP.

<% foreach (sort keys %vals) { %>
    <select name="<%= $_ %>">
      <option value="1"<%= ($vals{$_}) ? ' selected' : '' %>>On
      </option>
      <option value="0"<%= ($vals{$_}) ? ' selected' : '' %>>Off
      </option>
    </select>
<% } %>

You may also want to look at HTML::Embperl, which has a feature to automatically select combo box items (or fill in any other form elements) for you.
