[RESOLVED] Add item to a combobox items collection at run time

[ebellounisoft]

How can I Add an item to a combobox items collection at run time, permanently not temporarily, so next time I open my interface it will be there ?. Thank you.

To add it at run time I am using this code. It adds every item I put in, but when I close and open again my app again these items are not in the combobox items collection. So Is not working.

Private Sub ComboBox1_LostFocus(sender As Object, e As EventArgs) Handles ComboBox1.LostFocus
        Dim newItem As String = ComboBox1.Text
        AddElement(ComboBox1, newItem)
    End Sub

Sub AddElement(ByRef control As ComboBox, ByVal newItem As String)
        Dim idx As Integer
        If control.FindString(newItem) >= 0 Then
            idx = control.FindString(newItem)
        Else
            idx = control.Items.Add(newItem)
        End If
        control.SelectedIndex = idx
    End Sub
