Single Instance of EXE

How can I ensure that my EXE cannot be executed a second time while a previous instance is currently running?

Thanks,
Kevin

Use this code on Form_Load of your application:

Code:

---

Private Sub Form_Load()
    If App.PrevInstance Then
        MsgBox "The application is already running. You cannot run more then 1 copy of this application."
        End
    End If
End Sub
