Singleton Application the Simple Way!

It is very simple to understand the programming i have done in this example.

The Program first gets all running current process if the count is greater than one that means there are more than one instance running so it gives an error and closes the application
 
    Private Sub Form1_Load(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles MyBase.Load
        If Process.GetProcessesByName(Process.GetCurrentProcess.ProcessName).Length() > 1 Then
            MsgBox("This is a Single instance Applicaton " & vbNewLine & "* Another Instance is Already Running", MsgBoxStyle.OKOnly, "Single Instance Application")
            End
        End If
    End Sub
