Thread.Sleep

If you want to keep reading the value of a property (10 seconds) that
keeps changing,
how would you do it. I tried this, but it did not work
Thread th = new Thread(new ThreadStart(Rea dMe));
th.Start();
Thread.Sleep(30 00);
th.Abort();
Thread.Sleep(10 00);

JPSutor,

I wouldn't use a polling mechanism like this. Rather, I would have some
sort of notification on class which indicates when the property changes.
The framework has a standard for things like this.

The first (pre .NET 2.0) is to have an event on your class named
<property name>Changed. This event is of type EventHandler, and you fire it
when the event changes.

If you are using .NET 2.0, you should use the INotifyProperty Changed
interface to indicate when a property changed (it's more efficient in
general than the old method).

If you want to poll the property, then I would use a timer, instead of
causing a thread to sleep, and check the property value there.

Hope this helps.

I might also add that a while loop with a sleep duration works quite
well. I noticed in pre .Net 2.0 the timer just wasn't reliable enough
in certain situations. A while loop seemed to work well as an alternate
solution.

Hi,

Thread th = new Thread(new ThreadStart(Rea dMe));
th.Start();
Thread.Sleep(30 00);
th.Abort();
Thread.Sleep(10 00);

This does not work cause Thread.Sleep refer to the current thread , the
thread where the method is called, for this to work Thread.Sleep should be
in the ReadMe() method.
No need to call Abort btw.
ITOH, I would not do it this way, I would use a timer .

Or even better an event.

Nicholas,
What I am trying to accomplish is this.
I have a form with a progress bar on it.
When I make a call to a method in another class to iterate through a
recordset, I want the progress bar to show the progress.
When I try referencing the form from my class I get an error message.
What I'm trying to do here is to set a property value and read it in
each time the timer fires. I realize this isn't the most effecient
method, but my first try did not work

Hi, I have a problem coding a UDP Server/client. The server needs to send big amounts of data over UDP. The problem however is that you can't send as fast as you like. (All packets will be dropped due to the fact that a router can't handle the huge number of packets (most likely the first one the packets hit)). To fix this problem you need to increase/decrease the speed according to packetloss.

I've got a routine that builds a table using different queries, different SQL Tables, and adding custom fields. It takes a while to run (20 - 45 seconds) so I wrote a thread to handle the table population. Whenever I call the thread, I pass it a structure containing the table and a few other parameters. The table goes in as a reference, but the other items are passed normally.
