threadpool

The Microsoft .NET Base Class Library provides several ways to create a thread and start it. Basically the invocation is very similar to every other one providing the same kind of service: create an object representing an execution flow (or more), assign it a delegate representing the execution flow to execute and, eventually, depending on delegate signature, an object as a parameter. Well, there are two approaches (essentially): 1) Using the System.Threading.Thread class. Thread curr = new Thread(myfunction); /* In a class, myfunction is a void taking an object */ curr.Start(new Object()); /*

I have been reading about the thread-pool pattern and I can't seem to find the usual solution for the following problem. I sometimes want tasks to be executed serially. For example, I read chunks of text from a file and for some reason I need the chunks to be processed in that order. So basically I want to eliminate concurrency for some of the tasks . Consider this scenario where the tasks with * need to be processed in the order they were pushed in. The other tasks can be processed in any order. push task1 push task2 push task3 * push task4 * push task5 push task6 * .... and so on In the

Could anyone help me i have a problem I'm trying to get this code to work in the background via threadpool but i cannot seem to get it to work i keep getting this error: Cross-thread operation not valid: Control 'ListBox3' accessed from a thread other than the thread it was created on. Here is the code i am using: private void DoWork(object o) { var list = ListBox3; var request = createRequest(TxtServer.Text, WebRequestMethods.Ftp.ListDirectory); using (var response = (FtpWebResponse)request.GetResponse()) { using (var stream = response.GetResponseStream()) { using (var reader = new

I am testing an application where we have a list view with list of images retrieved over network. When i run the application on android device 2.3.3 (WIFI speed 512 KBPS) and check the DDMS (Thread Viewer), the number of threads keeps increasing till 50 from 25. But when i test the same application on device 4.0 (WIFI speed 5 MBPS), number of threads did not increase. Can anyone help me understand why this is happening ? Is it due to android OS difference or any other reason ? Thanks in advance. Ponyets Are you useing AsyncTask . After Android 3.0, the default behavior of AsyncTask is execute

I am using ThreadStatic variables to store some data, but I am worried that the data I store on the thread will still be there after I am finished with it and release back to the ThreadPool. Do I need to worry about clearing my ThreadStatic variables before I am finished with the thread? Or will the ThreadPool do this for me before "passing it out" for the next QueueUserWorkItem? This is especially important for me because I need to make sure that other threads in my app have a clean slate to work from in terms of ThreadStatic variables. Thanks! The thread pool (by design) keeps the threads
