Asynchronous methods - callback method is never called

lvq684

Hi. I have this console based Asynchronous VS project that works fine. And then i have a remoting project which also works fine. I want to edit the remoting project so it is non-blocking, using asynchronous calls. I´ve tried different examples, but I cant get it to work. None of them seems to call my callback method back. Here is the relevant snippets: The remote object:

....
public class MultiContainer : MarshalByRefObject, IMultiContainer
{
public string GetClientsList()
{
Thread.Sleep(1000);
return Program.ServerForm.GetClientsList();
}
....

The client which accesses the remote object with asyn call:

namespace Client
{
public partial class Form1 : Form
{
Server.IMultiContainer mc;
private delegate string Delegate();

    public Form1()
    {
        InitializeComponent();
    }

    private void button1\_Click(object sender, EventArgs e)
    {
        mc = new Server.MultiContainer();
        Delegate del = new Delegate(mc.GetClientsList);
        AsyncCallback callback = new AsyncCallback(Callback);
        del.BeginInvoke(callback, null);
    }

    private void Callback(IAsyncResult ar)
    {
        //this callback method is never called...
        Delegate del = (Delegate)((AsyncResult)ar).AsyncDelegate;
        richTextBox1.Text = del.EndInvoke(ar);
    }

...

Been sitting with this problem for hours, hope you can help! Thanks alot :)
