Question

I have a common comms library that i have written to communicate with our hardware over TCP/IP

The common library allows both the clients application and our engineer tool to share common code.
The common library runs threads that need to return data back to forms.

I have some working code but I feel that there must be an easier way to do it.

This is a simplified version of what i have…

namespace EngineerTool
{

    public delegate void DelegateSearchFinished();

    public partial class MainForm : Form
    {
        public DelegateSearchFinished d_SearchFinished;
        Discover discovery;

        public MainForm()
        {
            InitializeComponent();
            discovery = new Discover(this.FinishedSearchInvoke);
            d_SearchFinished = new DelegateSearchFinished(this.FinishedSearch);
            discovery.Start();
        }

        public void FinishedSearchInvoke()
        {
            this.Invoke(this.d_SearchFinished, new Object[] {});
        }

        public void FinishedSearch()
        {
            // Search has finished here!
        }
    }
}

namespace DiscoveryTool
{
    public delegate void DelegateSearchFinished();

    public class Discover
    {
        DelegateSearchFinished _callFinished;

        public Discover(DelegateSearchFinished callFinished)
        {
            _callFinished = callFinished;
        }

        public void Start()
        {
            // starts thread and stuff
        }

        public void ThreadWorker()
        {



            _callFinished();
        }

    }
}

Answer 1

What about creating an event on the Discover class and the Form subscribes to the event, instead of passing delegates around.
