Force Style on non-forum page?

[Killsparer]

Hullo,

i?m currently using the following code in the file test_template.php to display a... well... test_template:

<?php
error_reporting(7);

require('./global.php');

eval("dooutput(\"".gettemplate('test_template')."\ ");");

?>

Currently, the content is shown in the style the user has chosen. But is there a way to force a specific style to be shown, just for this page?

Something like "dooutput (.getstyle(1));"
