Create a Timer and set its Interval to the number of milliseconds until the desired shutdown time. In the Tick event handler execute the required code to shutdown the machine. There are various ways to do that, e.g, shutdown.exe and the ExitWindowsEx API function, and they have been posted about many times before so a forum search will give you what you need there.

I made a shutdown program a while ago here's some of my code to maybe help you out a bit

Timer1.Start()
        lblCurrentTime.Text = System.DateTime.Now
        If Me.lblCurrentTime.Text.ToString().Equals(Me.dtpTime.Value.ToString()) Then
          
    Private Sub ShutdownAt()
        If Me.cbForce.Checked Then
            Dim processes() As Process = Process.GetProcesses()
            For Each processParent As Process In processes
                Dim processNames() As Process = Process.GetProcessesByName(processParent.ProcessName)
                For Each processChild As Process In processNames
 
                    Try
                       
                        If Not processChild.MainWindowTitle.Equals(Me.Text) Then
                            processChild.CloseMainWindow()
                            processChild.Kill()
                            processChild.WaitForExit()
                        End If
                    Catch exception As Exception
 
                    End Try
 
                Next
            Next
        End If
        System.Windows.Forms.Application.Exit()
        Select Case cbSelect.SelectedIndex
            Case 0
                Me.Close()
                WindowsController.ExitWindows(RestartOptions.LogOff, True)
            Case 1
                Me.Close()
                WindowsController.ExitWindows(RestartOptions.PowerOff, True)
            Case 2
                Me.Close()
                WindowsController.ExitWindows(RestartOptions.Reboot, True)
            Case 3
                Me.Close()
                WindowsController.ExitWindows(RestartOptions.ShutDown, True)
            Case 4
                Me.Close()
                WindowsController.ExitWindows(RestartOptions.Suspend, True)
            Case 5
                Me.Close()
                WindowsController.ExitWindows(RestartOptions.Hibernate, True)
        End Select
        'End If
    End Sub

Where is the heart here. Let a novice crash his computer like that.

Good shut down procudure. NOT!!!! Kill all your processes is bad bad bad!!

If Not processChild.MainWindowTitle.Equals(Me.Text) Then
                            processChild.CloseMainWindow()
                            processChild.Kill()
                            processChild.WaitForExit()
                        End If

isn't that what shutting down your pc does? terminate all active processes?

certaintly it's alot cleaner to close them yourself before calling windows to shutdown.


just food for thought though.

I put if cbForce is checked if you check it then you choose the option for force shutdown to close out all open program's if not leave it unchecked to just shutdown the basic way it's just a option tho

[PENNYSTOCK]

I haven't tried in extesivly, but the second parameter of this tells the shutdown to force it anyway. However, it give the process at least a chance.

WindowsController.ExitWindows(RestartOptions.ShutDown, True)

When I ran you your code, it crashed my system and I recieved the blue screen of death!
