I am putting together some code to shutdown or restart a remote PC but it just wont work!

Imports System.Net.NetworkInformation
Imports System.Net
Imports System.Threading
Imports System.Text
Imports System.Diagnostics

Public Class Shutdown

    Private _isNull As Object


    Private Sub Shutdown_Load(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles MyBase.Load
        txtPCName.Text = Main.txtHostName.Text()
    End Sub

    Private Sub txtPCName_TextChanged(sender As Object, e As EventArgs) Handles txtPCName.TextChanged

    End Sub

    Private Sub btnShutdown_Click(sender As Object, e As EventArgs) Handles btnShutdown.Click

        Dim result = MessageBox.Show("The computer " & txtPCName.Text & "  will be shut down, are you sure you want to do this?", "Warning", MessageBoxButtons.YesNo, MessageBoxIcon.Exclamation)
        If DialogResult = Windows.Forms.DialogResult.Yes Then
            System.Diagnostics.Process.Start("C:\Windows\System32\shutdown.exe", " /m \\" & txtPCName.Text & " /s /t 10 /d p:0:0")
            Dim result2 = MessageBox.Show("The shutdown command has been sent to " & txtPCName.Text & " and it will shutdown in 10 seconds unless you click Cancel...", "Shutdown Command Sent", MessageBoxButtons.OKCancel, MessageBoxIcon.Information)
            If DialogResult = Windows.Forms.DialogResult.Cancel Then
                System.Diagnostics.Process.Start("C:\Windows\System32\shutdown.exe", " /m \\" & txtPCName.Text & " /a")
            Else

            End If
        ElseIf DialogResult = Windows.Forms.DialogResult.No Then
        End If

    End Sub

    Private Sub btnRestart_Click(sender As Object, e As EventArgs) Handles btnRestart.Click
        Dim result = MessageBox.Show("The computer " & txtPCName.Text & " will be restarted, are you sure you want to do this?", "Warning", MessageBoxButtons.YesNo, MessageBoxIcon.Exclamation)
        If DialogResult = Windows.Forms.DialogResult.Yes Then
            Process.Start("C:\Windows\System32\shutdown.exe", " /m \\" & txtPCName.Text & " /r /t 10 /d p:0:0")
        ElseIf DialogResult = Windows.Forms.DialogResult.No Then
        End If
    End Sub
End Class

Open in new window


The first message appears with a Yes/No question but then nothing else happens after that and the shutdown command doesnt run.

Can anyone offer some advice?

first of all test from command line, may be you need credentials like username or passowrd
if you can do it from command line, read here:

I solved it myself in the end. The problem was caused by the line:
"If Dialogresult = "
When it should have read:
"If Result = "

Here's the full code if anyone needs it...

    Private Sub btnShutdown_Click(sender As Object, e As EventArgs) Handles btnShutdown.Click
        Dim Timer As String
        Timer = ComTime.Text
        Dim result = MessageBox.Show("The computer " & txtPCName.Text & " will be shut down, are you sure you want to do this?", "Warning", MessageBoxButtons.YesNo, MessageBoxIcon.Exclamation)
        If result = Windows.Forms.DialogResult.Yes Then
            System.Diagnostics.Process.Start("C:\Windows\System32\shutdown.exe", " /m \\" & txtPCName.Text & " /s /t " & Timer & " /d p:0:0")
            Dim result2 = MessageBox.Show("The shutdown command has been sent to " & txtPCName.Text & " and it will shutdown in " & Timer & " seconds unless you click Cancel...", "Shutdown Command Sent", MessageBoxButtons.OKCancel, MessageBoxIcon.Information)
            If result2 = Windows.Forms.DialogResult.Cancel Then
                System.Diagnostics.Process.Start("C:\Windows\System32\shutdown.exe", " /m \\" & txtPCName.Text & " /a")
            Else

            End If
        ElseIf result = Windows.Forms.DialogResult.No Then
        End If
    End Sub
