u can try following codes u can find process object in System.Diagnostics namespace int pcnt =0; Process curproc = null; Process[] pr = Process.GetProcesses("ur machine name"); foreach(Process pr2 in pr) { if(pr2.ProcessName.Equals("ur application name")) { pcnt=pcnt+1; curproc = pr2; } } if(pcnt>1) { MessageBox.Show("Application already running"); curproc.Kill(); }
