> Whats the advantage of using a structure of arrays?? It may or may not be an advantage. When deciding what type of data structure to use, you should always consider what your needs are. Ie, how do you plan on storing and using the data. In general, I don't often use 2d arrays because normally it makes more sense to use structures.

If you have a unique ID for each person, it would make more sense to use a structure that looked like so: people = structNew(); people["Ray Camden"] = structNew(); people["Ray Camden"].age = 29; people["Ray Camden"].rank = "Captain"; If you are storing session info, you can easily use session.urltoken as a primary key. If you want an easy way to copy session info to a variable, consider duplicate: application.peopleData[session.urltoken] = duplicate(session) Don't forget your cflocks if you aren't on cfmx. Also do not forget that when a session expires, the data will still be in the application scope. To get around this, you simply store the 'last hit' info in the application variable as well. You can use another structure as well: application.peopleData[session.urltoken] = duplicate(session) application.peopleDataLastHit[session.urltoken] = now(); Then when displaying info about the users online, if the person's "lastHit" value is older then your session timeout, you can remove them from the peopleData structure. ======================================================================= Raymond Camden, ColdFusion Jedi Master for Macromedia Email : [EMAIL PROTECTED] Yahoo IM : cfjedimaster "My ally is the Force, and a powerful ally it is." - Yoda ______________________________________________________________________ This list and all House of Fusion resources hosted by CFHosting.com.
