Windows Service Command Reprint

Oncustomcommand executes when the service Control Manager (SCM) passes a custom command to the service. Specifies actions to take when a command with the specified parameter value occurs.

The only values for a custom command so can define in your application or use in Oncustomcommand is those between 1 256.
integers below correspond to system-reserved values.

Create one Windows Service & Implement Below Code in Service:

namespaceMywindowsservice
{
PublicPartialclassService1:ServiceBase
{
PublicenumSimpleservicecustomcommands{Command1 = Command2, =129, Command3 = 130};

PublicService1 ()
{
InitializeComponent ();
}

        protected  void  onstart (string [] args)
        {
        }

        protected  void  onstop ()
        {
       }

        protected  void  oncustomcommand (int  command)
        {
             base . Oncustomcommand (command);

             switch (command)
                 case (int ) simpleservicecustomcommands . COMMAND1:
                 //command1 implementation
                 break ;

                 case (int ) simpleservicecustomcommands . COMMAND2:
                  break ;

Case (int) simpleservicecustomcommands. Command3:
//COMMAND3 Implementation
                     ;
                 default :
                      break ;
 
            }       
        }
   }}

Call Windows Service customcommands from User application:

• Create Service Controller Object
  
  ServiceController Controller = new ServiceController("Mywindowsservice");
  
• start the Windows service
  
  controller.refresh (); Gets the current status of Service
      if   ( Controller.status == servicecontrollerstatus . Stopped)
       {
   controller.start ( );
      }
   
• Call Customcommands Using Controller Object
  

  if (Controller.status = = ServiceControllerStatus. Running)
  {
  Controller.executecommand (128);
  }
