C# Minimize to system tray on close

Hi In my c# application I am trying to minimize application to systems tray, when the form is closed. Here is the code I have tried.

   public void MinimizeToTray()
    {
        try
        {
            notifyIcon1.BalloonTipTitle = "Sample text";
            notifyIcon1.BalloonTipText = "Form is minimized";

            if (FormWindowState.Minimized == this.WindowState)
            {
                notifyIcon1.Visible = true;
                notifyIcon1.ShowBalloonTip(500);
                this.Hide();
            }
            else if (FormWindowState.Normal == this.WindowState)
            {
                notifyIcon1.Visible = false;
            }
        }
        catch(Exception ex)
        {
            MessageBox.Show(ex.Message);
        }

    }

and I am calling the method to form closing event. But the problem is its not minimizing to tray. Its just closing the form.

You can handle FormClosing Event such as micsoft Form Closing Event as Following example of C#

private void Form1_Closing(object sender, System.ComponentModel.CancelEventArgs e)
    {
        // Determine if text has changed in the textbox by comparing to original text.
        if (textBox1.Text != strMyOriginalText)
        {
            // Display a MsgBox asking the user to save changes or abort.
            if (MessageBox.Show("Do you want to save changes to your text?", "My Application",
                MessageBoxButtons.YesNo) == DialogResult.Yes)
            {
                // Cancel the Closing event from closing the form.
                e.Cancel = true;
                // Call method to save file...
            }
        }
}

e.Cancel = true; code will be always cancelling the event even if you shut the computer down, but here is a code that helps you:

 private void Form1_FormClosing(object sender, FormClosingEventArgs e)
 {
     if (e.CloseReason == CloseReason.UserClosing)
     {
          myNotifyIcon.Visible = true;
          this.Hide();
          e.Cancel = true;
     }
 }

It will allow closing the form programmaticaly.

   namespace MinimizeTrayNotification
     {
      public partial class Form1 : Form
       {
    public Form1()
    {
        InitializeComponent();
    }

    private void MinimzedTray()
    {
        notifyIcon1.Visible = true;
        notifyIcon1.Icon = SystemIcons.Application;

        notifyIcon1.BalloonTipText = "Minimized";
        notifyIcon1.BalloonTipTitle = "Your Application is Running in BackGround";
        notifyIcon1.ShowBalloonTip(500);

    }

    private void MaxmizedFromTray()
    {
        notifyIcon1.Visible = true;
        notifyIcon1.BalloonTipText = "Maximized";
        notifyIcon1.BalloonTipTitle = "Application is Running in Foreground";
        notifyIcon1.ShowBalloonTip(500);


    }



    private void Form1_Resize(object sender, EventArgs e)
    {
        if(FormWindowState.Minimized==this.WindowState)
        {
        MinimzedTray();
        }
      else  if (FormWindowState.Normal == this.WindowState)
        {

            MaxmizedFromTray();
        }
        }

    private void notifyIcon1_MouseDoubleClick(object sender, MouseEventArgs e)
    {
        this.WindowState = FormWindowState.Normal;
        Form1 frm = new Form1();
        frm.Show();
        MaxmizedFromTray();


    }

    private void notifyIcon1_MouseClick(object sender, MouseEventArgs e)
    {
        this.WindowState = FormWindowState.Normal;
    }

    private void Form1_FormClosing(object sender, FormClosingEventArgs e)
    {
        if (e.CloseReason == CloseReason.UserClosing)
        {
            e.Cancel = true;
            this.WindowState = FormWindowState.Minimized;
            this.ShowInTaskbar = false;
            this.Hide();

        }


    }

    private void notifyIcon1_Click(object sender, EventArgs e)
    {
        this.WindowState = FormWindowState.Normal;
        notifyIcon1.BalloonTipText = "Normal";
        notifyIcon1.ShowBalloonTip(500);

To minimize when closing set WindowState to Minimized

private void Form1_FormClosing(Object sender, FormClosingEventArgs e) {
    e.Cancel = true;
    WindowState = FormWindowState.Minimized;
}

Write a event in Form Closing event.

 private void Form1_FormClosing(object sender, FormClosingEventArgs e)
 {
        e.Cancel = true;                         
        Hide();
 }

And write using Custom menu strip for notification icon for to show.

You should cancel the FormClosing event and then call your MinimizeToTray() function.

This is done through the Cancel property of the FormClosingEventArgs.

Also, consider using a bool somewhere to allow closing the Form in some conditions, such as if you're using a File > Exit menu or something:

private void Form1_FormClosing(object sender, FormClosingEventArgs e)
{
    if(!allowClosing)
    {
        e.Cancel = true;
        MinimizeToTray();
    }
}

You need to use the FormClosing-Event.

private void Form1_FormClosing(Object sender, FormClosingEventArgs e) {
    e.Cancel = true;
    MinimizeToTray();
}
