Hi,<br>I'm having problems with two Combo boxes;<br>Historique & Annuaire are both Comboboxes, <br>I need to use the _click methode to change a value of historique when an object is selected. But if no obj are selected and i select an obj of annuaire the application crashes because Historique.SelectedItem is not valid.<br>How can I test if Historique has at this precise time a selected item ?<br>
