Write the following code for the button 1

Dim books As New AutoCompleteStringCollection

        Dim conn As New SqlConnection("Data Source=NITIN\SQLEXPRESS;Initial Catalog=library;Integrated Security=True")
        Dim cmd As New SqlCommand("select btitle from book", conn)


        Dim dr As SqlDataReader = cmd.ExecuteReader()

        While dr.Read()


        End While

        Me.ComboBox1.AutoCompleteSource = AutoCompleteSource.CustomSource
        Me.ComboBox1.AutoCompleteCustomSource = books
        Me.ComboBox1.AutoCompleteMode = AutoCompleteMode.Suggest
