How to restart a program in code?

[UncleRonin]

In my app I have a bunch of options which can be changed. When these are changed and saved I want the program to restart itself. How can you do this programmatically?

How can I make it close itself completely and THEN reopen itself? Is this actually possible?

If the application is not single instance then do this:

Sub restartApplication()
 Me.Hide()
 Process.Start(Application.ExecutablePath)
 Me.Close()
End Sub

New in .Net 2.0 is this method, but there are some info you should read in documentation to know how it works.

Application.Restart()
