WinCC OA C# API: finalize program when stopping manager

[Karel@RCM]

Dear all,

Recently I started building a WinCC OA manager with the C# API released in version 15.

I called my manager "WCCOASimitManager". This manager has to control a TCP/IP client for a remote interface connection to another application, in my case SIMIT.

In order to provide a stable application, the manager needs to disconnect the TCP/IP client when I stop (or kill) the manager in the WinCC OA Console, otherwise SIMIT will freeze.

When I stop my manager, 4 events are logged in the event logger. I hoped this would provide me answers. I'll guess I have to listen for the "SIGTERM" event in my C# application, but I couldn't find any information in the documentation about this event.

I would expect to program something like this:

OaManager.ManagerStopped += (vcsender, vce) =>
{
Client.proxy.SimDisconnect(clientID, out result, out errormessage); // Disconnect the SIMIT Client
};

Any ideas on how I can implement a deconstructor/termination event into my C# application when the manager is stopped?

Thanks in advance!

Regards,

Karel van Leeuwe

The following procedure provided a possible solution!

Code: Select all

class Program
    {
        static void Main(string[] args)
        {
            // Handle the ProcessExit event to know when the process is exiting.
            AppDomain.CurrentDomain.ProcessExit += new EventHandler(CurrentDomain_ProcessExit);
        }
        static void CurrentDomain_ProcessExit(object sender, EventArgs e)
        {
            Console.WriteLine("Finalize program");
        }
    }
}
