Hi Max3vil,

A simple solution would be something like this

private void button1_Click(object sender, EventArgs e)
{
Process[] processes = Process.GetProcessesByName("notepad");

if (processes.Length > 0)
MessageBox.Show("Notepad already started");
else
{
Process p = new Process();
p.StartInfo = new ProcessStartInfo("notepad.exe");
p.Start();
}
}

This is not very robust though. If another program would call itself
notepad the code above will fail.
