I won't say it is impossible.
I will say that if your Perl is running on a Unix server and you are trying to get that fine of control over a remote Windows machine then one of three things should be true:
- Your client-side logic is running on your client's machine (probably in Java or JavaScript).
- Your client is running a custom application which gives you more power over them than a browser provides.
- You have broken into your client's machine using techniques which their system administrator should not be happy about.
These are listed in increasing order of difficulty. Perl could be used to do any of them, but is not necessarily the most appropriate language to use. Implementing any of them requires knowledge of how to manipulate the client-side which is highly OT for this site. | [reply] |
