No, not possible. Why would you want to?
Hi, because i wonder other programs like visual basic also have their own dll, so i just wan to know wheter moodle have such file. thanks
It is very close to impossible, alas. But you can run in on a local machine without a network connection, if that's what you are after. You still need the web server software et cetera, but you can connect to the server from the same machine that it is running on.
