I would like to...

[Christina N]

.... reward the one that can show me how to use an array to keep track of the
active sessions (session-ids, logontimes, etc) in my ASP.Net application. Of
course I can't reward anyone here, but still... Aren't there anyone of you
clever guys that can show me how to do this? Anyone..?

I can't find help on this issue anywhere.
Please help me,
Christina

Why an array? Just write the info to a DB with each session_start and clear
it in the session_end

But I need to be able to query the array to find out for how long the
different sessions have been inactive. That's my main challenge in this
matter..
Can you help me?

as i showed you in my reply to your last post you can add user at
session_start

similarly you can query the user specific info like say the last access data
time by using set the coding in
Application_BeginRequest.
get your user specific object and update it with the current time

Can't fault your persistence. This is not a complete solution, but here are some thoughts (vb syntax).

1. Create a class to store the elements of each session you want to save, e.g.
Public Class MySession

Private m_SessionID As String
Public Property SessionID() As String
Get
Return m_SessionID
End Get
Set(ByVal Value As String)
m_SessionID = Value
End Set
End Property

Private m_loginTime As DateTime
Public Property LoginTime() As DateTime
Get
Return m_loginTime
End Get
Set(ByVal Value As DateTime)
m_loginTime = Value
End Set
End Property

End Class

2. Create a property at the global application level to store your list of
sessions. Using arraylist is one way. I'd probably do this right within
global.asax, e.g.

Private m_Sessions As ArrayList
Public ReadOnly Property MySessions() As ArrayList
Get
If IsNothing(m_Sessions) Then
m_Sessions = New ArrayList
End If
Return m_Sessions
End Get
End Property

3. When each session starts (I'd use global.asax), create a new instance of MySession (see above), fill the values with whatever, and add to the global list, e.g.

Sub Session_Start(ByVal sender As Object, ByVal e As EventArgs)
' Create a new Session holder.
Dim mySession As New MySession
mySession.SessionID = Session.SessionID
mySession.LoginTime = Date.Now
MySessions.Add(mySession)
End Sub

4. When each session ends, use Session ID to find it in the global list and remove the MySession entry.

A few warnings:

a. I think that a module-level variable (my arraylist) is a poor way to
persist the list. My understanding is that ApplicationStart only fires once for the application, but within that the application might choose to fire up multiple instances of the actual httpapplication class, which would give you multiple instances of your arraylist (each would then only have some portion of the list). Better probably to use Application state or Cache (or persist to disk if you want a permanent record).

b. SessionEnd does not happen as fast as you might want. By default, a
session only times out after a user is gone for 20 minutes, so your list
might contain more entries than people who are actually connected. Might not be a problem in your case, or you can give people a way to sign out and do
session.abandon.

c. ApplicationEnd can happen in a variety of ways that you might not expect (not just when all the sessions have finally ended). For one, ApplicationEnd happens if you make a change to a shadowed file (e.g. web.config,
global.asax, etc.). In this case, the application ends all sessions, goes
down, brings itself back up, and restarts the sessions as each guy does
something again. The users don't know the difference, it's just that if
you're looking at session start times, for example, you might see a real
recent start time for a guy you "think" has been on all day.

I ran the above and it worked as expected: start a bunch of sessions, go get the arraylist in MySessions (cast context.applicationinstance to "global" and you can get at your new public property of global), and when you dump out the list in each session you see all the sessions. As I said above, there's
probably a better way to persist the arraylist.

There are a number of people out here who understand this stuff very, very
well. I'm hoping if I've gotten any of this wrong above that they'll jump in. Have fun.

While using a database in a web farm is more scalable, using memory versus
arrays is definitely a plus in terms of performance. On a non-web-farm web,
I would go with an array or Collection (Collection would be better, as you
can easily add and remove items).
