Introduction

This is a Simple method to make a Application Singleton.

Background

I had seen some Examples on Codeproject but those were a little complex this is the simple method.

Using the code

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

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
