ActionScript 3.0 :: Passing Additional Parameters To Function Listeners?

hboxvar.addEventListener("mouseDown",dosomething(3 43));
hboxvar.addEventListener("mouseDown",dosomething(1 23));
hboxvar.addEventListener("mouseDown",dosomething(1 2342));
public function dosomething( somenumber:Number ):void {
//do something here
}

I try to do above function but I need to pass variable from hboxvar but not from inside function suggested by macromedia.

any one frustated with this way of passing multiple parameter which depends on what to pass in flex 2 using addEventListener ?

Passing additional parameters to function listeners You can pass additional parameters to function listeners depending on how you add the listeners. If you add a listener with the addEventListener() method, you cannot pass any additional parameters to the listener function, and that listener function can only declare a single argument, the Event object (or one of its subclasses).
