How about you write the code yourself? There are examples of doing this all over the place. Make some sort of an effort.

You've got the function to pass the text from form1 to form2 but you also need something to pass the amended information from form2 back to form1 e.g. in form1

C#

public void SetNewListBoxValue(string newValue)
{
    listBox1.Items.Add(newValue);
}

and in form2

C#

private void okButton_Click(object sender, EventArgs e)
{
    f1.SetNewListBoxValue(textBox1.Text);
}
