Windows

Is there a way to put a status text into the Windows taskbar notification area?

admin

I’d like to show a short status text in the Windows notification area, so not an icon, but a text of a few characters the content of which changes regularly and comes from a text file.

Is there a simple way to put such a text into the notification area?

Answer

Thanks to @LotPings who pointed me to an other answer, I managed to create a VB script which regularly reads text from a file and displays it in the notification area (the 29 on the picture).

Currently it’s only two characters, but you can use a smaller font to display more.

Note that I’m not a Windows programmer, nor a VB programmer, so the code is not pretty, I just copy pasted from examples until I made it work.

Here’s the code which you can compile with vbc.exe (e.g. C:WindowsMicrosoft.NETFramework64v4.0.30319vbc.exe):

Imports System

Public NotInheritable Class Form1
    Inherits System.Windows.Forms.Form

    Private aTimer As System.Timers.Timer

    <System.STAThread()> _

        System.Windows.Forms.Application.Run(New Form1)
    End Sub 'Main

    Public Sub New()

        Me.components = New System.ComponentModel.Container
        Me.contextMenu1 = New System.Windows.Forms.ContextMenu
        Me.menuItem1 = New System.Windows.Forms.MenuItem

        ' Initialize contextMenu1
        Me.contextMenu1.MenuItems.AddRange(New System.Windows.Forms.MenuItem() _
                            {Me.menuItem1})

        ' Initialize menuItem1
        Me.menuItem1.Index = 0
        Me.menuItem1.Text = "E&xit"
