An application might save its settings when executing the main form’s

_FormClosing routine. This example saves the selected items in three combo

boxes (cmbBitRate, cmbPort, and cmbHandshaking):

 Settings.Default.BitRate = CInt(cmbBitRate.SelectedItem)
Settings.Default.ComPort = cmbPort.SelectedItem.ToString
Settings.Default.Handshaking = DirectCast(cmbHandshaking.SelectedItem, Handshake)

Settings.Default.Save()
