Passing Arguments for a filter to a view (views 3) in code scenario?

Hi Drupal Friends,
I am working on a Views 3 Project and I'm stuck with this issue:

So far:
A Service-Method that reads a view and returns the results:
$products_result = views_get_view_result($viewName);

Goal:
Now I want to add a filter (default or contextual???) for setting the maximum price (e.g. "maximum price": field_price < max_price)

Problem:
I did setup the filter and it works properly. But I am not able to pass the arguments in code scenario. The documentation says that views_get_view_result(...) can expect additional arguments. But I didn't find any examples for that case. I tried passing the arguments as follows:
views_get_view_result($viewName, NULL, 666 );
views_get_view_result($viewName, NULL, array( 666 ) );
views_get_view_result($viewName, NULL, array( "field_price_value" => 666 ) );
But I wasn't lucky. What am I doing wrong?

I found a workaround. But I'm not really happy with that, 'coz it's a little too dirty:
I can simulate the exposed form filter and set the GET-Parameter via code before I get the view results like this:
$_GET["field_price_value"] = 664;
That works. But I'm sure there is a better way with the Views API.

Thanks in advance!
