Help with Remoting object

Well, you're talking about the client (consumer), right? You replace your Console.Writeln() statements with myform.ListBox1.Items.Add() methods. If the listbox is out of scope, add the form's namespace to the using clause, and provide a public accessor method, like this: class myform : System.Windows.Forms.Form { ... public void addtolistbox(string astring) { //add the item this.ListBox1.Items.Add(astring); //scroll to the end of the list so you can see the new item. this.ListBox1.SelectedIndex = this.Listbox.Items.Count-1; } }
