Run cmd in background

I have this code, but I am not sure how to set it up to run the command in the background.  What do I do with the dll?  Is this something I need to add a referance too?  Also I do I call this from a button?

you simply run the posted function and it will hide the console in the background.
nothing else need to be done.
for the sake of other experts, the question relate to how to run console command in the background.
Private Shared Function StartBackgroundProcess(procPath As String, cmdLine As String) As Integer
	Dim psi As New ProcessStartInfo(procPath, cmdLine)
	psi.WindowStyle = ProcessWindowStyle.Hidden
	psi.CreateNoWindow = True
	psi.UseShellExecute = False

	Dim proc As Process = Process.Start(psi)
	ShowWindow(proc.MainWindowHandle, 0)
	proc.WaitForExit()
	Return proc.ExitCode
End Function

Open in new window

Opps, here it is

<DllImport("user32.dll")> _
Public Shared Function ShowWindow(hWnd As IntPtr, nCmdShow As Integer) As Boolean
End Function

Private Shared Sub AddUserToGroup(userDn As String, groupDn As String)
      Dim exitCode As Integer = StartBackgroundProcess("dsmod", String.Format("group ""{0}"" -addmbr ""{1}""", groupDn, userDn))
      If exitCode <> 0 Then
            Console.WriteLine("Could not remove user {0} from group {1}", userDn, groupDn)
      End If
End Sub

Private Shared Sub RemoveUserFromGroup(userDn As String, groupDn As String)
      Dim exitCode As Integer = StartBackgroundProcess("dsmod", String.Format("group ""{0}"" -rmmbr ""{1}""", groupDn, userDn))
      If exitCode <> 0 Then
            Console.WriteLine("Could not remove user {0} from group {1}", userDn, groupDn)
      End If
End Sub

Private Shared Function StartBackgroundProcess(procPath As String, cmdLine As String) As Integer
      Dim psi As New ProcessStartInfo(procPath, cmdLine)
      psi.WindowStyle = ProcessWindowStyle.Hidden
      psi.CreateNoWindow = True
      psi.UseShellExecute = False

      Dim proc As Process = Process.Start(psi)
      ShowWindow(proc.MainWindowHandle, 0)

u need to add a reference to System.Runtime.InteropServicesother than than in the button click event handler, add the code which runs the console command.for example:dim exitCode as Int = StartBackgroundProcess("iisrest", "/stop")
