Perhaps if you show some of your code.

I want to know whether the session id is unique when a group of people browsing through the same site, same page at the same time.
Can anybody help?
Please send me the code which will generate the session id.

SessionID is generated in RAM on the Webserver and It is not a persistent property. It is unique at the time is it created.but not guaranteed to be unique. 
Same SessionID might be used again after your Web server has been restarted. This means that you shouldn't attempt to track the same user over time by using her SessionID.

I don't think so. I think it's stored as a cookie in client machine.

But that is generated by the server !!!

It's created on the server, and also stored as a cookie on the client.
The server has to keep track of the session id:s that it has created, so that it can verify that the id exists when the client sends another reuqest.
In earlier versions of IIS, the Session object was used to keep track of session. In more recent versions, the Session object is only retained if any data has been stored in it, otherwise only the session id is retained, and a new Session object is created for every request.

This is what I meant. Is it possible to access the session value from the id specified ? I mean if I pass the session id through querystring, is it possible to access the value ?

No. A Session object can only be accessed by a request that is associated with the sesson, i.e. sends the session id in the correct cookie.

This should really be asked on the ASP.NET forum.

Hello,
It's clear that during design time you will not see a control which is not implemented with the designer.
Apart from, that your code doesn't even compile.
Marking a control as static on a Form is just nasty, dirty and bad bad bad!
I think your problems started as you were not able to path the value (string) back to your form.
So you came up with the static solution!
You could path the instance of the form over the constructor of the "clsBatch" class and then call a non static method, which adds the item to the non static ListBox (which was placed over the designer).
class clsBatch
{
frmMain MainForm = null;
public clsBatch(frmMain mainForm)
{
MainForm = mainForm;
}
public void fnBatch()
{
if(MainForm!=null)
MainForm.status("Hi");
}
}
A nicer and more OO solution would be to use delegates, which is very good discriped in this article[^] from Colin!
But, the problem of not seeing your "Hi" will still be the same!
What you can do is:
Make a UserControl and place a Listbox on it.
Set the "Dock" property to "Fill".
Add the the code there and place the usercontrol, over the designer, on the Form.
You can instanciate the "clsBatch" in the constructor and call the method there.
public class ListBoxControl : System.Windows.Forms.UserControl
{
private System.Windows.Forms.ListBox myListBox;
private System.ComponentModel.Container components = null;
public ListBoxControl()
{
InitializeComponent();
clsBatch objbatch = new clsBatch(this);
objbatch.fnBatch();
}
public void status(string strMsg)
{
myListBox.Items.Add(strMsg);
}
...
The reason it will work now, is that for the usercontrol it's runtime now!
Hope it helps!

Set a breakpoint, that's the option that makes sense. Or Console.WriteLine will output to the output window in VS.

i need code how do i use ilist in c# i want to store database values in an IList but i dont know how do I pleasse mention related methods also
thanks

Hello,
First IList is an Interface, so you can't instanciate it directly to add you datas.
You could create your own class which implements the IList interface,
or use framework classes which already do so (like ArrayList).
But before you do that, I would suggest to read the doku![^]
All the best,
Martin

Hi, I have made a web service and when I build the application the Begin and End Methods for the service do not appear. For this I created the Begin and End Method Myself, but still when I compile it, the Begin and End methods do not appear.
Also, the windows application where I am adding the web reference to this service, the Begin and End methods do not appear and therefore I am not able to make aynchronous calls to the methods of the webservice.
Its urgent. Kindly help. I am using C#.

None.

So, you're saying you want to search your database. How is that a major task ?
Sandep H S wrote: ....its urgent...
That's great, because everyone else today has said 'it's not urgent', thus pushing you to the head of the queue....
Do you know any SQL at all ? Or does your site not have a database back end ( i.e. it's a disaster )
