Collect the input through your form, then on submit, use a script to launch a new window and send the info to your results page with the query string. Or cookies.

You really can't prevent right clicking, at least with any consistency. Many browsers let users disable javascript that does this, and others have plugins that do it.

I want when user clicks the link: Mortage calculator appear a window 500x400 with html file: http://www.kolectivavillas.com/papho.../loan_calc.htm

when user presses submit results appear in the same size window...

How I generally de-activate right-mouse-click in js in a doc html or asp or php ? where include this code ?
