How to run ShellExecute in Javascript?

Hi

How to run this code in my browser? I tried, and notepad did not open. 

<script language="VBScript">
    function fnShellExecuteVB()
        dim objShell
        set objShell = CreateObject("shell.application")        
objShell.ShellExecute "notepad.exe", "", "", "open", 1        
set objShell = nothing
    end function
