Introduction

This code piece demonstrates how to ensure only one instance of your application is running

In the program's main form, change the Main method to the following:


static void Main() 
{
	Process ThisProcess = Process.GetCurrentProcess();

	Process [] AllProcesses = Process.GetProcessesByName(ThisProcess.ProcessName);

	if (AllProcesses.Length > 1)
	{
		MessageBox.Show(ThisProcess.ProcessName + " is already running", 
			ThisProcess.ProcessName, 
			MessageBoxButtons.OK, 
			MessageBoxIcon.Error);
	}
	else
	{
		Application.Run(new MainForm());
	}
}

Hi the name space is System.Diagnostics.Process. You can use the same code with c# syntax for process class.
