A simple example... (note: more validation should be done, this is just an example...)

// a basic html form

<form action='script.pl' method='post'>
NAME: <input type='text' name='name' size'8'...

You can do this with in Perl with Win32::API or with Win32::OLE using the object wscript!

Using Win32::OLE will allow you to change the background image without the need to a shut down!...
