问题 I use Dreamweaver 8 at work, and recently I've been having an issue with open files. When I move focus away from Dreamweaver to another piece of software (usually firefox for testing the results of uploaded files), and then move back to Dreamweaver I get a prompt saying: "This file has been modified outside of Dreamweaver. Do you want to reload it". Edit: this is for every single file I have open in Dreamweaver so is quite unbearable! Clicking yes or no both show exactly the same page!

问题 I use prototype on the client side. I need to change picture on the page without reloading. So in my .js file I change the src of a picture and it works ok. But I also need that if the same image requested, it would alse request the server to know if this image has changed, and reload if needed.

问题 Okay so I am making a custom feature for my OP-Prison server, one of the things that I need to do is get an integer from the players.yml file, check if it is >= one, if it is take away one, save it and then if it is still above one then they can repeat the action untill it's 0.
