Surely a web thing, right?

Hi,

u can use Application level variables and make use of the events in Global.asax

Steps:

1. Declare Variables

private static int totalNumberOfUsers = 0;
    private static int currentNumberOfUsers = 0;


2. Add Properties
public static int TotalNumberOfUsers
{
  get
  {
    return totalNumberOfUsers;
  }
}

public static int CurrentNumberOfUsers
{
  get
  {
    return currentNumberOfUsers;
  }
}



3. Session Start Event

protected void Session_Start(Object sender, EventArgs e)
{

  totalNumberOfUsers += 1;
  currentNumberOfUsers += 1;

}


4.Session End Event

protected void Session_End(Object sender, EventArgs e)
{
  currentNumberOfUsers -= 1;

}


5.Access variables from other page

int currentNumberOfUsers = HitCounters.Global.CurrentNumberOfUsers;
int totalNumberOfUsers = HitCounters.Global.TotalNumberOfUsers;


Refer http://imar.spaanjaars.com/223/howto-create-a-hit-counter-using-the-globalasax-file-in-aspnet-1x[^]


:thumbsup: Revert for further clarification
   
For web application, try:
Write code in Global.asax file which interacts with the entire application.
The sample code is given below:
void Application_OnStart(Object Sender, EventArgs E)
        {
            Application["CurrentUsers"] = 0;
        }
        void Session_OnStart(object Sender, EventArgs E)
        {
            Application.Lock();
            Application["CurrentUsers"] = System.Convert.ToInt32(Application["CurrentUsers"]) + 1;
            Application.UnLock();
        }
        void Session_OnEnd(object Sender, EventArgs E)
        {
            Application.Lock();
            Application["CurrentUsers"] = System.Convert.ToInt32(Application["CurrentUsers"]) - 1;
            Application.UnLock();
        }
