问题 I would like to create time limited version of a game I am developping in C++. I already meet some program that create files I am still not able to delete, and other that created registry key very hard to delete (because there were several sub key and needed to change owner to the deeper first, delete it go up, change owner...). Then I think the only way is to create something in the computer that is not (or hardly) deletable to mark the beginning of trial. I know how to create key or file

问题 Yesterday I was speaking with a developer, and he mentioned something about restricting the insertions on database field, like, strings such as -- (minus minus). At the same type, what I know is that is a good approach to escape HTML chars like < , > etc. Not -- . Is this true? Do I have to worry about -- , ++ ? Is it more like a myth or old stuff?

问题 I know the basics of .htaccess, but freely admit to being a non-expert when it comes to mod_rewrite. The problem: I have a sqlite db file in the document root (no, I can't move it out of here) called data.sqlite . This file is accessed internally by PHP files, however, I want to protect this file from being 'downloaded' by the user typing the db URL directly into their browser.
