We use an input box to get a hobby from the user and add it to the list box.
Public Class Form1 'your name Private Sub BtnAdd_Click(sender As Object, e As EventArgs) Handles BtnAdd.Click 'ask user for hobby, add to list Dim hobby As String hobby = InputBox("Enter a hobby", "Hobby") If hobby <> "" Then LstHobbies.Items.Add(hobby) End If End Sub Private Sub LstHobbies_SelectedIndexChanged(sender As Object, e As EventArgs) Handles LstHobbies.SelectedIndexChanged Me.Text = "I like " + LstHobbies.Text + " too!" End Sub Private Sub BtnExit_Click(sender As Object, e As EventArgs) Handles BtnExit.Click End End Sub Private Sub BtnAdd_MouseEnter(sender As Object, e As EventArgs) Handles BtnAdd.MouseEnter Me.BackColor = Color.Blue End Sub End Class
