thank you that is great that helps alot i also have a similar need for a listbox not sure if it is the right control to use but i want to list for example in the listbox the string parameter of objects that i have stored in an array and that everytime a new object is found in the array the listbox is updated so the listbox needs to update with the change to the array the class i have is similar to this class server { string name; string ip; } cheers again -Tristan

Hi Tristan One approach would be defining a property. private string myVariable; private string MyVariable { set { myVariable = value; if (myVariable != value) { Form2.textBox1.Text = myVariable; } } get { return myVariable; } } MyVariable = new value // this will make your textbox's value change also You must define Form2.textBox1 as public so that you'll be able to access it from another form.
