Session timeout

Question

Hi

i have desktop app. and need to activate the timeout session , i use this code and use it in the main form in the app ,but doesn't work

public Form1()
{
    InitializeComponent();
    
    sessionTimer = new Timer();
    sessionTimer.Interval = 180000; // 3 minutes (180,000 milliseconds)
    sessionTimer.Enabled = false;
    sessionTimer.Tick += SessionTimer_Tick;
}
private void SessionTimer_Tick(object sender, EventArgs e)
{
    // This code will be executed when the session times out
    // Perform actions such as logging the user out or closing the application
    // For example, you can display a message and then close the application:
    MessageBox.Show(" Session Timeout", "Session Timeout", MessageBoxButtons.OK, MessageBoxIcon.Warning);
    // Perform logout or application closing logic here
    Application.Exit();
}
private void StartSession()
{
    // Call this method when the session starts (e.g., when the user logs in)
    // Start the timer to begin the countdown
    sessionTimer.Start();
}
private void ResetSessionTimer()
{
    // Call this method to reset the session timer (e.g., when the user interacts with the application)
    // Stop the current timer and start it again to reset the countdown
    sessionTimer.Stop();
    sessionTimer.Start();
}
private void StopTimer()
{
    sessionTimer.Stop();
}
private void MainForm_MouseClick(object sender, MouseEventArgs e)
{
    // Call ResetSessionTimer() whenever the user interacts with the application
    // This will reset the session timeout countdown after each interaction
    ResetSessionTimer();
}

any help ??

The code you've provided seems to be on the right track for implementing a session timeout feature in your desktop application. However, there might be a few reasons why it's not working as expected. Let's go through some potential issues and solutions: StartSession Method : I don't see where you're calling the StartSession() method in your code. This method should be called when the user logs in or when a new session starts. Without calling this method, the timer won't start, and the session won't be timed out. private void Form1_Load(object sender, EventArgs e) { StartSession(); } Event Handling : Ensure that you have the MainForm_MouseClick event handler properly set up to call the ResetSessionTimer() method. The code you've provided for this method seems fine. Timer Enabling : The timer should be enabled ( sessionTimer.Enabled = true; ) when you want the timer to start ticking. It seems that you've initialized the timer with sessionTimer.Enabled = false; , which means it won't start counting until you explicitly enable it. public Form1() { InitializeComponent(); sessionTimer = new Timer(); sessionTimer.Interval = 180000; // 3 minutes (180,000 milliseconds) sessionTimer.Enabled = true; // Enable the timer here sessionTimer.Tick += SessionTimer_Tick; } With these changes in place, your code should work as expected. The timer will start when the form loads, and each time the user interacts with the application, the timer will be reset. If the user remains inactive for more than 3 minutes, the session timeout event will occur, and the application will display a message and exit.

Many thanks for your help . this is what i change sessionTimer.Enabled = true; // Enable the timer here :)

The code seems correct. Ensure that StartSession() is called when the user logs in. In MainForm_MouseClick , use ResetSessionTimer() to reset the timer after user interaction. However, confirm that MainForm_MouseClick is indeed being triggered for interactions. Double-check the event binding and timer interval accuracy. If still not working, verify if any conflicting code affects the timer or UI updates. If persistent issues persist, consider debugging further or consult with a developer for assistance.

public partial class Form1 : Form { private Timer sessionTimer; // Declare the timer public Form1() { InitializeComponent(); sessionTimer = new Timer(); sessionTimer.Interval = 180000; // 3 minutes (180,000 milliseconds) sessionTimer.Tick += SessionTimer_Tick; StartSession(); // Start the session timer when the form is initialized } private void SessionTimer_Tick(object sender, EventArgs e) { // This code will be executed when the session times out // Perform actions such as logging the user out or closing the application // For example, you can display a message and then close the application: MessageBox.Show("Session Timeout", "Session Timeout", MessageBoxButtons.OK, MessageBoxIcon.Warning); Application.Exit(); // Close the application on session timeout } private void StartSession() { // Call this method when the session starts (e.g., when the user logs in) // Start the timer to begin the countdown sessionTimer.Start(); } private void ResetSessionTimer() { // Call this method to reset the session timer (e.g., when the user interacts with the application) // Stop the current timer and start it again to reset the countdown sessionTimer.Stop(); sessionTimer.Start(); } private void StopTimer() { sessionTimer.Stop(); } private void MainForm_MouseClick(object sender, MouseEventArgs e) { // Call ResetSessionTimer() whenever the user interacts with the application // This will reset the session timeout countdown after each interaction ResetSessionTimer(); } }
