losing args sent using BeginInvoke

I was recently referred to the following articles which I
found very useful:

I start a thread from a Windows.Forms.Form which is supposed to use BeginInvoketo safely update a text field on the form by calling UpdateUI.
UpdateUI gets called, but I don't seem to be able to get anything from theSystem.EventArgs I passed in.

I'm using a very simple example from MSDN:
http://msdn.microsoft.com/msdnmag/is...02/Multithread ing/default.aspx
but it just doesn't seem to work.

What am I doing wrong?

private void StartOperations() {
statusTxt.Text = "StartOperations";
Thread pdcThread = new Thread(new ThreadStart( RunningInThread )); pdcThread.Start();

}
private void RunningInThread () {
BeginInvoke(new System.EventHandler(UpdateUI), new object[] { this, newMyProgressEvents("Pdc shutdown issued") });
}
private void UpdateUI(object o, System.EventArgs e) {
MyProgressEvents pe = (MyProgressEvents) e;
statusTxt.Text = pe.msg;
}
public class MyProgressEvents : System.EventArgs {
public string msg = "";

public MyProgressEvents(string s) {
msg = s;
}

}
