[2005] ?? Label Counting with Loops ??

Here is my code. the lblProxyListCount.Text = cboProxies.SelectedIndex + 1 & " / " & cboProxies.Items.Count is not working until the loop is over, i want it to step through the count while the program is working. also the lblStatusBar.Text = "( Testing for working Proxies.... )" is not even showing either. Do labels not have precedence during a loop?

Code:

---

 
  Private Sub btnTestProxies_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles btnTestProxies.Click
        'connect to proxies in list, if connected successfully
        'add proxy to cboActiveProxies
        lblStatusBar.Text = "( Testing for working Proxies.... )"

        Dim sck As Socket = Nothing
        Dim i As Integer
        Dim IP As String = Split(cboProxies.Text, ":")(0)
        Dim Port As String = Split(cboProxies.Text, ":")(1)

        ' when proxies do not connect, nothing gets added to cboActiveProxies
        ' when test button is clicked lblStatusBar does not change text either
        ' its like labels are not taking any precedence

        On Error Resume Next
        For i = 0 To cboProxies.Items.Count - 1
            sck = New Socket(AddressFamily.InterNetwork, SocketType.Stream, ProtocolType.Tcp)
            sck.Connect(IP, Port)
            If sck.Connected Then
                cboActiveProxies.Items.Add(cboProxies.Text)
            End If
            cboProxies.SelectedIndex = cboProxies.SelectedIndex + 1
            lblProxyListCount.Text = cboProxies.SelectedIndex + 1 & " / " & cboProxies.Items.Count
        Next i

        ' lblActiveProxiesCount.Text = cboActiveProxies.SelectedIndex + 1 & " / " & cboActiveProxies.Items.Count
        cboActiveProxies.SelectedIndex = 0

        sck.Close()
        tmrStatusBar.Enabled = True

If you are using a single thread then it's too busy running your loop to repaint the controls. Either use a worker thread to run the loop so the UI thread is free to repaint the controls or else call the Refresh method of a control after you change its content.
