button command password

Hi again,

I'm sorry to aking all these questions but I have almost finish my program, I want it to be functionnal :3

After the Excel security, I would put one on the "STOP" button of my program. Indeed, currently, averyone can press on STOP and my program is useless (the operator will not be in front of the PC everytime). The computer have to be protected from people to warn.

So, is there a way to ask a "password" or any other security when the operator press on STOP ?

I already found the "pwsample.prj" but I don't know what to do with that (I work on LW2009)

Thank you for your time,

Matthieu
