Hello again...

I use for my combobox this code... but i have a problem with this!
If i hit twice the combobox the data from the file "jd.mbm" is duplicating!

Code:
Private Sub cmb_judet_DropDown(ByVal sender As Object, ByVal e As System.EventArgs) Handles cmb_judet.DropDown

Me.cmb_judet.SelectAll()

Dim str As IO.StreamReader = IO.File.OpenText(Application.StartupPath & ".\data\jd.mbm")

While Not str.EndOfStream

Dim line As String = str.ReadLine()

Me.cmb_judet.Items.Add(line)

End While

End Sub

How can i hit the combobox more than once without duplicating the data ?!

Thanks in advice!
