command line - c# register commandline argument don't start new instance -

application c:\pinkpanther.exe running , application wrote in c#. other application starts c:\pinkpanther.exe purplealigator greengazelle orangeorangutan , not start new instance of c:\pinkpanther.exe these arguments, running c:\pinkpanther.exe register , react somehow.

how it?

edit!!!: i'm sorry pinkpanther.exe , ruzovyjeliman.exe caused confusion - translated question native language , missed :(

to communicate other instance of application, need sort of inter-process communication. apparently, wcf recommended form of ipc in .net. can code (using wpf, winforms similar):

[servicecontract] public interface isingletonprogram {     [operationcontract]     void callwitharguments(string[] args); }  class singletonprogram : isingletonprogram {     public void callwitharguments(string[] args)     {         // handle arguments somehow     } }  public partial class app : application {     private readonly mutex m_mutex;     private servicehost m_servicehost;     private static string endpointuri =         "net.pipe://localhost/ruzovyjeliman/singletonprogram";      public app()     {         // find out whether other instance exists         bool creatednew;         m_mutex = new mutex(true, "růžovýjeliman", out creatednew);          if (!creatednew)         {             // other instance exists, call , exit             callservice();             shutdown();             return;         }          // other instance not exist         // start service accept calls , show ui         startservice();          // show main window here         // can process instance's command line arguments     }      private static void callservice()     {         var factory = new channelfactory<isingletonprogram>(             new netnamedpipebinding(netnamedpipesecuritymode.none), endpointuri);          var singletonprogram = factory.createchannel();         singletonprogram.callwitharguments(environment.getcommandlineargs());     }      private void startservice()     {         m_servicehost = new servicehost(typeof(singletonprogram));         m_servicehost.addserviceendpoint(             typeof(isingletonprogram),             new netnamedpipebinding(netnamedpipesecuritymode.none),             endpointuri);          m_servicehost.open();     }      protected override void onexit(exiteventargs e)     {         if (m_servicehost != null)             m_servicehost.close();          m_mutex.dispose();         base.onexit(e);     } }
