Hi,

   I need to logout after a few mins when the user is idle. I have gone through with below forum link thread,

http://www.visualwebgui.com/Developers/Forums/tabid/364/forumid/27/threadid/18701/scope/posts/threadpage/3/Default.aspx

but i was not able to access the methods in the custom control. I have created a custom control named SessionTimeOut and i have copied and pasted the code accordingly after that i was not able to call the register() and other methods in the customcontrol. Kindly correct me know if i am doing something wrong and if any one have an alternative solution do let me know please.

Hi Ori Cohen,

    I will tell you what i have done in my application. I have created an user control and named it as SessionTimeout. And i have pasted the below code:

SessionTimeout.js

var timerPassCount = 0;
var timer; //used to check at every 20 sec the user intercation
var mTimeOut; //is the timeout in seconds specified in sessionstate tag from web.config
var mStrGuid;

function alertMessage() {
    Invoked");
}

function InitSessTimeOut(timeout) {
    mTimeOut = timeout;
    //mStrGuid = strGuid;
    document.body.onmouseover = function() { OnMove() };
    document.body.onkeypress = function() { OnMove() };
    //call the function at 10 sec
    timer = setTimeout("timedCount()", 20000);
}

function OnMove() {
    if (timerPassCount != 0) {
        timerPassCount = 0;
    }
}

function timedCount() {
    timerPassCount += 20;
    if (timerPassCount >= mTimeOut) {
        //log out the user
        Events_CreateEvent("LogSesOut", true);
        Events_RaiseEvents();
        return;
    }
    //call the function at 10 sec
    timer = setTimeout("timedCount()", 20000);
}

function LogOut() {
    clearTimeout(timer);
}

FrmMain.cs

And in my main form (which is displayed once the login is successful) i have created a timer and named it as SessionTimer and i have done the below in the main form,

frmMain_Load()

{

SessionTimer.start();

}

private void SessionTimeoutTimer_Tick(object sender, EventArgs e)
        {

            sessionTimeout.Register();
            sessionTimeout.LogOutEvent += new SessionTimeout.LogOutFct(sessionTimeOut_LogOutEvent);

            //20 mins by default
            int sessTimeOut = 1200;//1200;
            System.Web.Configuration.SessionStateSection sessionState = System.Configuration.ConfigurationManager.GetSection("system.web/sessionState") as System.Web.Configuration.SessionStateSection;
            if (sessionState != null)
                //sessTimeOut = (int)sessionState.Timeout.TotalSeconds;

                //sessionTimeout.SetTimeOut(sessTimeOut - SessionTimeoutTimer.Interval / 1000);
                sessionTimeout.SetTimeOut(((1 * 120000) / 60000) + 4);
            SessionTimeoutTimer.Stop();
        }

void sessionTimeOut_LogOutEvent()
        {
            //logout the session
            this.Context.Session.IsLoggedOn = false;
        }
 

I have kept a breakpoint in the SessionTimeout.js in the function InitSessTimeOut(timeout) it doesnt hit the breakpoint at all. Also i have found that in the SessionTimeout.cs file with the below function,

public void SetTimeOut(int timeOut)

{
            this.InvokeMethod("alertMessage");
            this.InvokeMethodWithId("InitSessTimeOut", new object[] { timeOut });

}
 

when i see the QuickWatch i am getting the below message "Expression has been evaluated and has no value".

Kindly let me know if i am going wrong somewhere. And i have waited for more than 10 mins and nothing has happened.

Hi Ori Cohen,

   I have solved the problem with a simple workaround. Thanks a lot.
