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);

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

I suppose that the error message you've got is about thread synchronization .
If so, try this :

public class YourForm : System.Windows. Forms.Form
{
private delegate void ProgressBarDele gate(Int32 floodPercent);

public void UpdateProgressB ar(Int32 floodPercent)
{
// Need thread synchronization ?
//
if (this.InvokeReq uired)
{
this.Invoke(
new ProgressBarDele gate(this.Updat eProgressBar),
floodPercent);

return;
}

// Update ProgressBar flood percent here...
}
}

public class YourWorkingThre ad
{
private YourForm parentForm;
private DataTable dataToProceed;

YourWorkingThre ad(YourForm parentForm, DataTable dataToProceed)
{
this.parentForm = parentForm;
this.dataToProc eed = dataToProceed;
}

public void ThreadedJob()
{
Int32 rowCount = dataToProceed.R ows.Count;

for (Int32 i = 0; i < rowCount; i++)
{
// Proceed dataToProceed.R ows[i] ...

// Update progress bar
//
if (i % 100 == 0)
parentForm.Upda teProgressBar(( Int32)((Double) i / rowCount + 0.5));
}
}
}

On behalf of the Python development team and the Python community, I'm happy to announce the release of Python 2.3.1 (final). Python 2.3.1 is a pure bug fix release of Python 2.3, released in late July.

Hi, Currently I have a thread thats spinning and doing a Thread.Sleep(someTime). I was thinking of changing this to Thread.Sleep(Timeout.Infinite); then when I have actual data in a collection to process in this thread, I was going to do a _thread.Interrupt(); Would this be a better approach to spinning a thread on ?

Hi all, I've got a server that handles a relatively high number of concurrent transactions (on the magnitude of 1000's per second). Client applications establish socket connections with the server. Data is sent and received over these connections using the asynchronous model. The server is currently in beta testing. Sporadically over the course of the day, I'll observe the thread count on the process (via perfmon) start climbing....

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.

According to the docs, calling Thread.Sleep(0) causes the thread to be "suspended to allow other waiting threads to execute." What happens if I call Thread.Sleep(500)? Do other threads not get a chance to execute during this time? What is the difference between the two? I have code that runs in a loop like this: Dim dResetTime As DateTime = DateTime.Now

Hi, I hope someone can help. I have written a simple form to demonstrate my problem/question. The code follows. The form starts a thread, which using delegates updates a label (Every second adds another dot to the label). This works great. However, when I put the GUI thread to sleep (Thread.Sleep), the thread seems to stall. At first I was expecting dots to still appear, but obviously as the GUI thread is asleep, they will not. ...

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.

Hi All, I've been trying to come up with a good way to run a certain process at a timed interval (say every 5 mins) using the SLEEP command and a semaphore flag. The basic thread loop was always sitting in the sleep command and not able to be interrupted. When the time came to set the semaphore flag to false (stopping the thread), my program would have to wait up to the entire sleep time to break out of the loop. I have finally found...

In Windows 11 and 10, there is no way to turn off the Windows Update option using the Control Panel or Settings app; it automatically checks for updates and installs any it finds, whether you like it or not. For most users, this new feature is actually very convenient. If you want to control the update process,...
