Taskbar notifications give nice touch to user interface design. Visual Basic NotifyIcon is the right control to implement taskbar notifications.
To begin with, Place a NotifyIcon
control on your Form1
Design. Click Choose Icon and select any icon file for it.
Paste the following code in Windows Application1
:
Public Class Form1
Private Sub Form1_Load(ByVal sender As System.Object, ByVal e As System.EventArgs) _
Handles MyBase.Load
NotifyIcon1.BalloonTipText = "Tool Tip Text for Windows Application"
NotifyIcon1.Text = "Windows Application"
NotifyIcon1.ShowBalloonTip(5000)
CreateContextMenu()
End Sub
Public Sub CreateContextMenu()
Dim contextMenu As New ContextMenu
Dim menuItem As New MenuItem("Exit")
contextMenu.MenuItems.Add(menuItem)
NotifyIcon1.ContextMenu = contextMenu
AddHandler menuItem.Click, AddressOf menuItem_Click
End Sub
Private Sub menuItem_Click(ByVal sender As Object, ByVal e As System.EventArgs)
Me.Close()
End Sub
End Class
Press F5 to run the application. At start of the application, we can see the balloon tip notification text. Context Menu is also working with an Exit option.
NotifyIcon ToolTipText is shown
NotifyIcon Text is visible when mouse is hovered
NotifyIcon Context Menu option
Code Description for NotifyIcon
- It is necessary to define the
BalloonTipText
before calling to show the BalloonTip
. At form load, we define the desired texts for Notify Icon and balloon tip notification.
CreateMenu()
method defines the context menu functionality for the Notify Icon. It is easy to understand the code with inline comments. Please have a look at our detailed post on Visual Basic Drop Down Menu for additional guidance.
menuItem_Click()
provides functionality when Exit option is selected from the Context Menu.
Changing the Notification Text
All you need to do is change the text of balloon tip and show the balloon tip:
Step 1
Change the text of BalloonTip
using the property BalloonTipText
.
Step 2
Show the BalloonTipText
using the method ShowBalloonTip
(timeout as integer).
Monitoring BalloonTip Clicked Event
Sometimes, it is necessary to call some method when user clicks the BalloonTipText
. To understand it, just add the following code in Form1
code and run the application.
Private Sub NotifyIcon1_BalloonTipClicked(ByVal sender As Object, ByVal e As EventArgs) _
Handles NotifyIcon1.BalloonTipClicked
MessageBox.Show("BalloonTipClicked event is called")
End Sub
When you click the BalloonTip
, a message box is shown as response. The main idea is to create a method for handling NotifyIcon1.BalloonTipClicked
event.
