Well, you can have a timer set to tick every 5 seconds, and handle the
event that gets fired? There are two such timers depending on whether it
is for winform or server usage.

Alternatively, you could have a worker thread looping with a Sleep(5000)?

Is a web page, do you have a example of the code on how to set the tick
for every 5 seconds?

Cheers!

At client side? Well there are javascript ways of doing this in the
browser - setInterval / setTimeout:

Sorry - I should have added; for more information, you might want to try
asking on one of the ASP.NET forums, but a clientside javascript call is
a bit OT for a C# language forum.

Well, short of a meta-refresh, you can't.

A html page lives at the client. The server can't do anything once the
page has gone to the client - the client has to deal with that.

Nitpick: not that this helps the OP, but there are at least three timer
classes in .NET. They are in System.Timers, System.Threadin g, and
System.Windows. Forms.

Trying using Thread.Sleep to "pause" the current thread.



using System.Threadin g;
public class Test
{
public Test()
{
Thread everyFiveSecond s = new Thread
(FunctionToRunE veryFiveSeconds );
updater.Name = "Updater - Thread";
updater.Start() ;

}

public FunctionToRunEv eryFiveSeconds( )
{
object.Do();
Thread.Sleep(50 00);
}

public SomeOtherWork()
{
while(true)
{
object.DoSometh ingElse();
}
}
}

I think that you can use ajax. But this is based on javascript.

Doing something server side every N second does not
fit well with the ASP.NET model.

Options I can see:

1) Start a thread (like in global.asax Application_Sta rt) that
updates some global data (like stored in a singleton) every N
second and pages gets info from that global data.

2) Run a Windows service that has the thread that updates some
data every N seconds and have pages request info via
a low overhead protocol (remoting, plain sockets etc.).

#1 is not good (in general it is not good to mess around
with threads in a context where the container manage threads
and there will be extra work to get it to work well over web app
restarts) and #2 is rather complex, but I think
that is the options.
