Alternate you can store ID and Value in an XML file if it is a fixed number of Items and the number of items are not going to change often. Reading from the XML file will be bit faster than Querying against the Database.

Use a variable in the code behind and access it via a property that increments it

You can't, no such thing exists in HTML, and that means the only way to do it, is to write a browser plug in, which is code that your users have to install, and will not be anything to do with ASP.NET.

Web.sitemap should contain the URL of the page where sitemap control resides

Hi Everyone,
I am using a web part in a page for the first time.To try how it works i did in a sample page where i first added a webpart manager and a webzone with a label control with some text.
When i try to run i get a run time error saying
"When connecting to SQL Server 2005, this failure may be caused by the fact that under the default settings SQL Server does not allow remote connections. (provider: SQL Network Interfaces, error: 26 - Error Locating Server/Instance Specified)"
I dont have sql server in my local machine but should it be needed.I am not trying to connect to database. Then why i couldnt run.
Kindly clarify me

Hi,
In my web application i want to maintain list of number of user is online.
If one of them close browser without sign out then he/she will not be displayed in list.
And also i want to restrict multiple login by one user in different browser.

You can do this with AJAX. Otherwise, you have to wait for their session to time out.

Easy, have an 'is logged in' property on the user table, if they are logged in, either log out the old session ( better ), or refuse login.

Is it a good practice on believing javascript for this ? In a worst case scenario, what will happen if user system got hanged and need a restart ? So the flag there in user table still show he is online, and prevents him from logging again.
I think there is no efficient methods for this. What do you say ?

If system is hanged, now he/or she has shutdown system,
now he/she wants to login once again then.
how do i change flag,

Well, AJAX is the only way you can find out if the browser was closed. It's wise to add code to manually clear sessions you know have timed out, also, if you must do this at all.
N a v a n e e t h wrote: So the flag there in user table still show he is online, and prevents him from logging again.
That's the main reason that I said it's better to kill the old session and allow a new login to take precedence.

Yes, it's messy, no matter how you look at it.

Yes it is.
It's not possible to believe on session_end also, which won't be fired all time, and it's specific for InProc.
I have seen some examples which explains this in much more efficient way by making use of cache. Cache timeout will be set as session timeout time and assign a callback function when cache timed out. Inside this function we will be able to update the flag.
This looks much closer to the problem. ?

With AJAX, you can capture a client side event when the browser is closed, and send a message to the server. That's what I was referring to. But, it's still messy. Turn the power off, that's the obvious example that you cannot code for.

Hi, Thanks for Reply
Can I check that current session_id is live or dead.
If i get that then i can compare it with session id stored in database,
if it is still live then i can restrict user from login.

Many times answered for the same question by different people. Try doing a serch on this discussion board.

To maintain online users, you should go with database. On closing browser using javascript onUnload event check the window size and if less than or equal to zero update the logout flag in database as false thru AJAX. On every time login show the online users with that flag as true.
Be simple and Be sample.
