Simple class for easily minimizing to tray and adding context menu with ONE line of code

This class allows the user to implement minimizing to tray in one line of code.


I usually like to implement the minimizing to the system tray feature in my applications... In addition, I also like to add a context menu to the icon which allows the user to restore the app from the tray or exit. After adding the same several lines of code to each application, I realized that it would be beneficial to streamline the process.

The Class

This class allows you to add this functionality in one line of code. The constructor takes the main form (Me) of your application, the text to add to the icon [optional], and the icon you want to display in the tray [optional - defaults to application icon].


Dim minToTray As New ClsMinToTray(Me, "MyApp is running...", myIcon)

Options: You can also choose the window state on restore and add to the context menu (the default tray icon menu has two items - Restore and Close).

Example (choose window state):

minToTray.restoreWindowState = FormWindowState.Maximized

Example (add to default context menu):

Private Sub Form1_Load(ByVal sender As Object, _
             ByVal e As System.EventArgs) Handles MyBase.Load
  minToTray.trayMenu.MenuItems.Add("New Menu Item", _
                          AddressOf NewMenuItem_click)
End Sub

Public Sub NewMenuItem_click(ByVal sender As Object, ByVal e As EventArgs)
  'Code Here
End Sub


This class seems to work well for me. I have used it in both VS2003 and VS2005b applications. The only issue I have ran into is in VS2005b. The ShowInTaskbar property of the main form (on multi-container) application seems to cause some anchoring problems (forms layout is affected on restore). I'm assuming this is a VS2005b bug...or maybe I'm missing something.

GeneralUrgent Help Needed :context menu does not appear Pin

Hi, I am writing a c# code that opens a file and searches for some condition and according to the condition that occuring tray icon changes.This should be done every 10 minutes.

I have coded this part well but I can not exit my application from a context menu item(exit) which never appears.

If I erase the line where my while loop appear, context menu appears and every thing goes well.

Do you have any suggestion where I might have made a mistake? I am a c# newbie and I cannot find the solution...

thanks for your help very much..

Here is the code:

using System;
using System.Drawing;
using System.Windows.Forms;
using System.Threading;
using System.Collections;
using System.ComponentModel;
using System.Data;
using System.IO;
using System.Diagnostics;
public class Form1 : System.Windows.Forms.Form
private System.Windows.Forms.NotifyIcon notifyIcon1;
private System.Windows.Forms.ContextMenu contextMenu1;
private System.Windows.Forms.MenuItem menuItem1;
private System.ComponentModel.IContainer components;
private System.Boolean check;

public Form1()
//this.ShowInTaskbar = false;
this.components = new System.ComponentModel.Container();
this.contextMenu1 = new System.Windows.Forms.ContextMenu();
this.menuItem1 = new System.Windows.Forms.MenuItem();
// Initialize contextMenu1
new System.Windows.Forms.MenuItem[] {this.menuItem1});

// Initialize menuItem1
this.menuItem1.Index = 0;
this.menuItem1.Text = "E&xit";
this.menuItem1.Click += new System.EventHandler(this.menuItem1_Click);

// Set up how the form should be displayed.
//this.ClientSize = new System.Drawing.Size(292, 266);

this.Text = "Notify Icon Example";

// Create the NotifyIcon.

this.notifyIcon1 = new System.Windows.Forms.NotifyIcon(this.components);
notifyIcon1.ContextMenu = this.contextMenu1;

// The Text property sets the text that will be displayed,
// in a tooltip, when the mouse hovers over the systray icon.
notifyIcon1.Text = "Form1 (Situation controller)";
notifyIcon1.Visible = true;
notifyIcon1.Icon = new Icon("Icon2.ico");
FileStream file = new FileStream("path.txt", FileMode.Open, FileAccess.Read,FileShare.Read);
StreamReader sr = new StreamReader(file);
string s;
bool control=false;
while((s = sr.ReadLine())!= null)
notifyIcon1.Icon = new Icon("Icon2.ico");
notifyIcon1.Icon = new Icon("Icon1.ico");
//bu kısmı degistirdim

protected override void Dispose( bool disposing )
// Clean up any components being used.
if( disposing )
if (components != null)

base.Dispose( disposing );

private void notifyIcon1_DoubleClick(object Sender, EventArgs e)
// Show the form when the user double clicks on the notify icon.

// Set the WindowState to normal if the form is minimized.
if (this.WindowState == FormWindowState.Minimized)
this.WindowState = FormWindowState.Normal;

// Activate the form.

private void menuItem1_Click(object Sender, EventArgs e)

notifyIcon1.Visible = false;



private void InitializeComponent()
// Form1
//this.AutoScaleBaseSize = new System.Drawing.Size(5, 13);
//this.ClientSize = new System.Drawing.Size(292, 273);
this.Name = "Form1";
this.ShowInTaskbar = false;
this.Load += new System.EventHandler(this.Form1_Load);


private void Form1_Load(object sender, System.EventArgs e)

public void HideApp()
this.WindowState = FormWindowState.Minimized;
public void ShowApp()
this.WindowState = FormWindowState.Normal;

static void Main()
Application.Run(new Form1());
