I use SwitchToThisWindow to bring the application to the forefront as in this example   static class Program        DllImport  User32 dll   SetLastError   true       static extern void SwitchToThisWindow IntPtr hWnd  bool fAltTab               lt summary gt          The main entry point for the application           lt  summary gt       STAThread      static void Main                 bool createdNew          int iP          Process currentProcess   Process GetCurrentProcess            Mutex m   new Mutex true   XYZ   out createdNew           if   createdNew                           app is already running                Process   proc   Process GetProcessesByName  XYZ                    switch to other process             for  iP   0  iP  lt  proc Length  iP                                  if  proc iP  Id    currentProcess Id                      SwitchToThisWindow proc 0  MainWindowHandle  true                              return                     Application EnableVisualStyles            Application SetCompatibleTextRenderingDefault false           Application Run new form             GC KeepAlive m

While I agree with everyone  this is no-nice behavior  here is code   DllImport  quot User32 dll quot    public static extern Int32 SetForegroundWindow int hWnd        SetForegroundWindow Handle ToInt32      Update David is completely right  for completeness I include the list of conditions that must apply for this to work   1 for David     The process is the foreground process  The process was started by the foreground process  The process received the last input event  There is no foreground process  The foreground process is being debugged  The foreground is not locked  see LockSetForegroundWindow   The foreground lock time-out has expired  see SPI GETFOREGROUNDLOCKTIMEOUT in SystemParametersInfo   No menus are active

Before stumbling onto this post  I came up with this solution - to toggle the TopMost property   this TopMost   true  this TopMost   false    I have this code in my form s constructor  eg   public MyForm                       Brint-to-front hack     this TopMost   true      this TopMost   false
