[2005] textbox issues

My program is basically downloading a file at a certain interval on a single thread and has a log window to show the status, it's suppose to put the timestamp into the textbox before it downloads the file but it doesn't do it until after it's finished downloading, i'm not sure why it would do that, anyone?

ex.

Code:

---

txtLog.Text += "[" & Date.Now() & "]  " & "Downloading..." + vbCrLf
        My.Computer.Network.DownloadFile _
        ("http://www.google.com/index.html", _
        currentdir)
txtLog.Text += "[" & Date.Now() & "]  " & "Done" + vbCrLf

---

Call the TextBox's Refresh method to force it to repaint before calling DownloadFile. Also, don't do this:

vb.net Code:

txtLog.Text += "[" & Date.Now() & "]  " & "Downloading..." + vbCrLf

but rather this:

vb.net Code:

txtLog.AppendText(String.Format("[{0:f}]  Downloading...{1}", _
                                Date.Now, _
                                Environment.NewLine))

You can change the 'f' to a different format string if you don't want the full short format.

thanks
