minimize app to system tray

Question

I have a Windows forms app powered by C# and Visual Studio 2010.

How can I minimize my app to system tray (not taskbar), then bring it back when doubled click in the system tray? any idea? also, how can I make some menu in the icon in system tray and when I right click it, it shows a menu like Login, Disconnect, Connect, something like that. Also, are there any methods to show like a baloon popping up from the system tray?

PS: I already added a notifyIcon, but I do not know how to use it.

Answer 1

• C# System Tray Minimize To Tray With NotifyIcon
• Minimize window to system tray

Handle the form’s Resize event. In this handler, you override the basic functionality of the Resize event to make the form minimize to the system tray and not to the taskbar. This can be done by doing the following in your form’s Resize event handler: Check whether the form’s WindowState property is set to FormWindowState.Minimized. If yes, hide your form, enable the NotifyIcon object, and show the balloon tip that shows some information. Once the WindowState becomes FormWindowState.Normal, disable the NotifyIcon object by setting its Visible property to false. Now, you want the window to reappear when you double click on the NotifyIcon object in the taskbar. For this, handle the NotifyIcon’s MouseDoubleClick event. Here, you show the form using the Show() method.

private void frmMain_Resize(object sender, EventArgs e)
{
    if (FormWindowState.Minimized == this.WindowState)
    {
       mynotifyicon.Visible = true;
       mynotifyicon.ShowBalloonTip(500);
       this.Hide();
    }

    else if (FormWindowState.Normal == this.WindowState)
    {
       mynotifyicon.Visible = false;
    }
}

Answer 2

I found this to accomplish the entire solution. The answer above fails to remove the window from the task bar.

private void ImportStatusForm_Resize(object sender, EventArgs e)
{
    if (this.WindowState == FormWindowState.Minimized)
    {
        notifyIcon.Visible = true;
        notifyIcon.ShowBalloonTip(3000);
        this.ShowInTaskbar = false;
    }
}

private void notifyIcon_MouseDoubleClick(object sender, MouseEventArgs e)
{
    this.WindowState = FormWindowState.Normal;
    this.ShowInTaskbar = true;
    notifyIcon.Visible = false;
}

Also it is good to set the following properties of the notify icon control using the forms designer.

this.notifyIcon.BalloonTipIcon = System.Windows.Forms.ToolTipIcon.Info; //Shows the info icon so the user doesn't think there is an error.
this.notifyIcon.BalloonTipText = "[Balloon Text when Minimized]";
this.notifyIcon.BalloonTipTitle = "[Balloon Title when Minimized]";
this.notifyIcon.Icon = ((System.Drawing.Icon)(resources.GetObject("notifyIcon.Icon"))); //The tray icon to use
this.notifyIcon.Text = "[Message shown when hovering over tray icon]";

Answer 3

don't forget to add icon file to your notifyIcon or it will not appear in the tray.

Answer 4

I'd go with

private void Form1_Resize(object sender, EventArgs e)
{
     if (FormWindowState.Minimized == this.WindowState)
     {
          notifyIcon1.Visible = true;
          notifyIcon1.ShowBalloonTip(500);
          this.Hide();    
     }
     else if (FormWindowState.Normal == this.WindowState)
     {
          notifyIcon1.Visible = false;
     }
}

private void notifyIcon1_MouseDoubleClick(object sender, MouseEventArgs e)
{
     this.Show();
     this.WindowState = FormWindowState.Normal;
}

Answer 5

try this

 private void Form1_Load(object sender, EventArgs e)
    {
        notifyIcon1.BalloonTipText = "Application Minimized.";
        notifyIcon1.BalloonTipTitle = "test";
    }

    private void Form1_Resize(object sender, EventArgs e)
    {
        if (WindowState == FormWindowState.Minimized)
        {
            ShowInTaskbar = false;
            notifyIcon1.Visible = true;
            notifyIcon1.ShowBalloonTip(1000);
        }
    }

    private void notifyIcon1_MouseDoubleClick(object sender, MouseEventArgs e)
    {
        ShowInTaskbar = true;
        notifyIcon1.Visible = false;
        WindowState = FormWindowState.Normal;
    }

Answer 6

This is the method I use in my applications, it's fairly simple and self explanatory but I'm happy to give more details in answer to your comments.

    public Form1()
    {
        InitializeComponent();

        // When window state changed, trigger state update.
        this.Resize += SetMinimizeState;

        // When tray icon clicked, trigger window state change.       
        systemTrayIcon.Click += ToggleMinimizeState;
    }      

    // Toggle state between Normal and Minimized.
    private void ToggleMinimizeState(object sender, EventArgs e)
    {    
        bool isMinimized = this.WindowState == FormWindowState.Minimized;
        this.WindowState = (isMinimized) ? FormWindowState.Normal : FormWindowState.Minimized;
    }

    // Show/Hide window and tray icon to match window state.
    private void SetMinimizeState(object sender, EventArgs e)
    {    
        bool isMinimized = this.WindowState == FormWindowState.Minimized;

        this.ShowInTaskbar = !isMinimized;           
        systemTrayIcon.Visible = isMinimized;
        if (isMinimized) systemTrayIcon.ShowBalloonTip(500, "Application", "Application minimized to tray.", ToolTipIcon.Info);
    }

Answer 7

At the click on the image in System tray, you can verify if the frame is visible and then you have to set Visible = true or false

Answer 8

...and for your right click notification menu add a context menu to the form and edit it and set mouseclick events for each of contextmenuitems by double clicking them and then attach it to the notifyicon1 by selecting the ContextMenuStrip in notifyicon property.

Answer 9

this.WindowState = FormWindowState.Minimized;
