I'm writing a static class for logging to be used across my developed solution. There are several components that will use it such as a console application, ASP.NET application, etc... For the logging to work, it needs to do some initial startup configuration before it can be used, and also some clean up when each application has finish...
Is there a threading model that works something like the following: while thread = nextAvailableThread(): thread.doWork(data) Such that when a thread is finished it triggers nextAvailableThread() to return this thread that just finished. This model would make distributing uneven data chunks between threads much easier as you could j...
We have a desktop application that performs a pretty rigorous set of calculations in a background thread. Portions of this calculation are performed in an unmanaged library that we access through interop. What we are finding is that, when we kick off the calculation, the UI thread becomes unresponsive for the duration of the calculatio...
I'm running a form in a second thread. If I do Ctrl-C to copy text on the clipboard, I get an Exception, "Current thread must be set to a single thread apartment (STA) before OLE calls can be made. (Using the clipboard involves OLE apparently). Putting the [STAThread] with my thread proc, which is the entry point of my second thread ...

I would like to somehow log every time Thread.interrupt() is called, logging which Thread issued the call (and its current stack) as well as identifying information about which Thread is being interrupted. Is there a way to do this? Searching for information, I saw someone reference the possibility of implementing a security manager. ...

I'm using the java.util.zip library and ZipOutputStream in order to create a zip file of a directory and all the files and directories under it. In my application, it is likely that another thread could be accessing these same files during the compression. I'm not an expert on file compression (or thread-safety, for that matter) so my ...

I have an application which needs to loop through all the lines in text files, over gigabytes in size. Some of these files have 10's or 100's of millions of lines. An example of my current (and synchronous) reading, looks something like... using (FileStream stream = new FileStream(args[0], FileMode.Open, FileAccess.Read, FileShare.R...

First, just a bit of background: One of our customers is experiencing CPU usage spikes for WebSphere instances running one of our web apps (other instances with other apps are fine). They have a test environment and a live environment (both iSeries) which both experience the problem - with a single app per instance setup. We have deploy...
Hello. I'm looking for an implementation of thread-safe blocking queue for .NET. By "thread-safe blocking queue" I mean: - thread-safe access to a queue where Dequeue method call blocks a thread untill other thread puts (Enqueue) some value. By the moment I'v found this one: http://www.eggheadcafe.com/articles/20060414.asp (But it's for...
After reading "Java concurrent in practice" and "OSGI in practice" I found a specific subject very interesting; Safe Publication. The following is from JCIP: "To publish an object safely, both the reference to the object and the object's state must be made visible to other threads at the same time. A properly constructed object can be s...

I am using the code below Thread.Sleep(5); at the end of a while loop. To try and get a 5ms delay between iterations. Sometimes it sleeps for 16ms. This I understand and accept, since it depends on when the CPU gets around to servicing the thread. However once it has woken the next iteration it seems to wake immediately after the sle...
In my WinForms application, I need to pop up a little custom dialog that stays on the screen for X amount of seconds and then disappears. So I use a System.Threading.Timer to invoke the _dialog.Close() method once the appropriate amount of time has elapsed. This of course means that I have to do the whole "if InvokeRequired BeginInvoke...
