Hy

This is a part from my code:

For ci = 0 To ListBox2.Items.Count
                If TextBox7.Text = ListBox2.Items.Item(ci) Then
                    GoTo Same_ID
                End If
            Next
            ListBox2.Items.Add(TextBox7.Text)

when it arrives at :            ListBox2.Items.Add(TextBox7.Text)

it gives me this error:

An unhandled exception of type 'System.ArgumentOutOfRangeException' occurred in system.windows.forms.dll
Additional information: Specified argument was out of the range of valid values.

What should i do??

For ci = 0 To ListBox2.Items.Count - 1
