• Should I include user_id in multiple tables?

  - by Drarok

  I'm at the planning stages of a multi-user application where each user will only have access their own data. There'll be a few tables that relate to each other, so I could use JOINs to ensure they're accessing only their data, but should I include user_id in each table? Would this be faster? It would certainly make some of the queries easier in the long run. Thanks!

• Regex to use each letter only once?

  - by gtcaz

  Is it possible to construct a PCRE-style regular expression that will only match each letter in a list only once? For example, if you have the letters "lrsa" and you try matching a word list against: ^[lrsa]*m[lrsa]*$ you're going to match "lams" (valid), but also "lamas" (invalid for our purposes because you only had one "a"). If your letter set was "lrsaa", you would want to match "lamas". Is this possible with regular expressions, or should I handle it programmatically?

• Click-Once install location from within application

  - by rein

  I'd like to programatically determine the "publish location" (the location on the server which contains the installation) of the click-once application I'm running. I know that the appref-ms file contains this information and I could parse this file to find it but the application has no idea as to the location of the appref-ms file and I can't seem to find a way of determining this location. Does anyone have any ideas how I can easily determine the publish location from within my application?

• Managing many objects at once.

  - by Jeff

  Hi, I want to find a way to efficiently keep track of a lot of objects at once. One practical example I can think of would be a particle system. How are hundreds of particles kept track of? I think I'm on the right track, I found the term 'instancing' and I also learned about flyweights. Hopefully somebody can shed some light on this and share some techniques with me. Thanks.
