facebook api: do i need to store each user's friends list in order to create a who's online component (between friends)? -


This is a general question about the creation of a Facebook application.

I want the user to have the who is online component which shows who among his friends is currently using the application.

Does this mean that I really need to store each user's friend list in my database and filter that user currently using my application?

It seems like a lot of things.

It also means that whenever I use my application, I should bring and store my friends

Is there any other way?

As you see, I did not explain what programming language I use, because I think it is irrelevant to the question.

Thank you!

No need to store a friend ID as you can get this information from Facebook ( Just run the FQL on the table) Just store the user id that is currently logged in (possibly the last_seen timestamp on the user table, then users are searching for the last 15 minutes Together with the app)

Something like this:

  • Every time a user updates the app with the user's previous_sync timestamp
  • Then retrieve the friend ID on the user login and submit them in one session if you do not want to retrieve this list, then each pageview (the maximum entry in the Friends list will not change during the session)
    • < Li> currently active if needed Find Friend ID among other users

Eclipse CDT variable colors in editor -

I hope this is a good question to ask here. This programming is related, so I thought it would be better than the superuser, so I am using the CDT C ++ Eclipse plugin. I know how the editor changes colors for some things But is there a way to do that all the variables are different colors? For example in KDEValue, it sets the local variables and square variables in different colors and bold square squares. Can I copy it to CDT? Eclips provides some level of color customization for text editor syntax You can see it on the following: There are many elements, including the Window> Preferences> C / C ++> Editor> Syntax color code that can be changed, assembly, Comments, Preprocessor and Doxian Under the code, it is possible to change the color of some variable types, such as global variables, local variable announcements, local variable references, and parameter variables. But I do not think the code is capable of changing the color of each variable declared....
