writing a procedure?

[kritikal]

how do you java people write a procedure? or something similiar

private sub CboLoad();
{
cboVehicleList.get_Items().Add("Car");
cboVehicleList.get_Items().Add("Boat");
cboVehicleList.get_Items().Add("Bus");
}

private void cboVehicleList_SelectedIndexChanged(Object sender, System.EventArgs e)
{
cboLoad();
}

this is based on some java knowledge and VB, how can I do this to add these items into a Combobox. any contributions will be appreciated

thanks
