    'now we have a connection, see if there are any mails on the server
    intMessCnt = popConn.GetMailStat()

    'now, see if we have returned any messages
    If intMessCnt > 0 Then

e9net，有一个解决方案，但我想出了最简单的方法只需添加以下行...

e9net, had a solution but i figured out the easiest way to do it by simply adding the following lines...

Private Sub ListBox1_SelectedIndexChanged(sender As Object, e As EventArgs) Handles ListBox1.SelectedIndexChanged
        RichTextBox1.Clear()
        RichTextBox1.Text = ListBox1.SelectedItem
    End Sub
