Notepad does not have such a feature. There are small apps with source code that you could modify to do what you ask. But often I find the office that wants such is tyrannical and won't allow an app to fit the need. They are lost at sea and you can't help them until the need overrides what is driving the rules.
Hi, I'm working in a company right now where notes are not allowed inside.. however i really need something to put on some of the information temporarily so I need help if someone of you guys knows how to create a notepad that can't be save for my co-workers
