Nov 22 2011 8:53 AM
Hello Friend!
My question is i can count online person by rely the ip address of client ??
My code is i have 1 page .aspx to display online person and the global.asax to increase or reduce online person.This is code in .aspx:
protected void Page_Load(object sender, EventArgs e)
{
if (!IsPostBack)
{
Response.Write("Person online is:");
Response.Write(Application["person_online"].ToString());
}
}
And this is .asax
protected void Application_Start(object sender, EventArgs e)
{
Application["person_online"] = 0;
}
protected void Session_Start(object sender, EventArgs e)
{
Application.Lock();
Application["person_online"] = Convert.ToInt32(Application["person_online"]) + 1;
//Session.Timeout = 1;
Application.UnLock();
}
protected void Session_End(object sender, EventArgs e)
{
Application.Lock();
Application["person_online"] =Convert.ToInt32(Application["person_online"])-1;
