How to pass an <asp:Label to a thread

I need to update the .Text of a label until the user logs out.

but get this error:

Error: Method name expected

I have listed the code below and the offending line of code is
delimited by

//The next line breaks: Error: Method name expected

Thank you,

In code behind of footer.aspx
A. Parameters:
1. ctlLabel is an <asp:Label
2. SessionStartTim e is the System.DateTime .Now of when the viewer
logged in
B. In Footer.aspx.cs, the thread is created with:

fFooter myFooter = new fFooter();
myFooter.Update (ctlLabel,Sessi onStartTime);
+++++++++++++++ +++++++++++++++ ++++++++++
using System;
using System.Threadin g;
namespace fFooter
{
/// <summary>
/// Summary Called from Footer.aspx.cs to update the footer with
/// Summary the time in minutes the viewer has been logged in.
/// </summary>
public class fFooter
{
public Thread myThread;
//Parameter(s)
System.DateTime xSessionStartTi me;
public void Update(System.W eb.UI.WebContro ls.Label yLabel,
System.DateTime
ySessionStartTi me)
{
xSessionStartTi me = ySessionStartTi me;
//The next line breaks: Error: Method name expected

myThread=new Thread(new ThreadStart(Upd ateLabel(yLabel )));

//The line above breaks: Error: Method name expected

myThread.Start( );
}
private void UpdateLabel(Sys tem.Web.UI.WebC ontrols.Label yLabel)
{
while ( true )
{
yLabel.Text = tTime(xSessionS tartTime);
Thread.Sleep(10 00);
}
}
private string tTime(System.Da teTime xSessionStartTi me)
{
string xx = "Active for: ";
System.DateTime dtBdate = xSessionStartTi me;
System.DateTime dtToday = System.DateTime .Now;
System.TimeSpan tsTotal = dtBdate - dtToday;
decimal xDECIMAL = Convert.ToDecim al(tsTotal.Tota lMinutes * -1);
int xINT = Convert.ToInt32 (decimal.Round( xDECIMAL,0));
if (xINT < 1 )
{
return "Just logged in";
}
else
{
if (xINT == 1)
{
return xx + "1 minute";
}
else
{
return xx + xINT + " minutes";
}

ThreadStart takes a delegate to a method with no params and no return (and
in 2.0 there's another version that accepts an object parameter). But I have a feeling that even if you got the delegate right, it's still not going to
do what you want. If you spin up another thread, the first thread will continue processing and render the result back to the browser. Your secondary thread will kick in at some point and try to update a control on the page that probabaly has already been rendered out to the client. In short, I think you're going to have problems. What exactly are you trying to do?
