How to automatically restart a program after it's closed - vb.net

Question

I'm developing a timer for my kids that will automatically shut down the computer once the time is up and I was trying to figure out a way that the program would automatically restart if it were to be closed via task manager.
I've posted my code for my program bellow if it's any help.

'use application setting boolean to not add same application to startup more than once

Answer 1

Here's a very basic windowless watchdog app.
Start with a standard WinForms project.
Add a Module.
Add a Public Sub Main to it.
Go to Project --> Properties --> Application Tab, and Uncheck the "Enable Application Framework" box.
Above that, change the "Startup object:" dropdown from "Form1" to "Sub Main".
The code...
Module Module1
Public Sub Main()
Application.Run(New Watchdog)
End Sub
End Module
Public Class Watchdog
Inherits ApplicationContext
Private AppToWatch As String
Private FullPath As String = "C:\WINDOWS\system32\calc.exe"
Private WithEvents P As Process
Public Sub New()
AppToWatch = System.IO.Path.GetFileNameWithoutExtension(FullPath)
Dim PS() As Process = Process.GetProcessesByName(AppToWatch)
If PS.Length = 0 Then
StartIt()
Else
P = PS(0)
P.EnableRaisingEvents = True
End If
End Sub
Private Sub P_Exited(sender As Object, e As EventArgs) Handles P.Exited
StartIt()
End Sub
Private Sub StartIt()
P = Process.Start(FullPath)
P.EnableRaisingEvents = True
End Sub
End Class

Answer 2

Compile the program as a service, and configure it to start automatically.
