In a C#.NET windows application I set the visibility of the checkbox to false: checkBoxLaunch.Visible = true; I started a thread. Thread th = new Thread(new ThreadStart(PerformAction)); th.IsBackground = true; th.Start(); The thread performs some stuff and sets the visibility to true private void PerformAction() { /* . .// some ...

What is the difference between thread affinity and process affinity? If I have two threads and I have a dual core machine then is it possible to run these two threads in parallel on the two cores? If I use processor affinity mask then I can control execution of a process on the cores but when I have to run threads on a particular core ...
Why the performance of following code is degrading when I use threads ? **1.Without threads int[] arr = new int[100000000]; //Array elements - [0][1][2][3]---[100000000-1] addWithOutThreading(arr); // Time required for this operation - 1.16 sec Definition for addWithOutThreading public void addWithOutThreading(int[] a...

I have a speed critical multithreaded program which involves data in a tree structure. Implemented as follows: typedef struct { // data pertaining to linkages, defining the architecture of the tree int parent_node; int child_node[MAX_CHILD_NODES]; int number_of_children; // data pertaining to info at each node f...
Heya! I'm using joda due to it's good reputation regarding multi threading. It goes great distances to make multi threaded date handling efficient, for example by making all Date/Time/DateTime objects immutable. But here's a situation where I'm not sure if Joda is really doing the right thing. It probably does, but I'm very interested ...
Can we set two thread or two task to execute with different processor affinity in C# Application? I have read about SetThreadAffinityMask but there is no example to have that used.. or Is there any way TPL(Task Parallel Libray) executes two thread/Task in with high priority to use 100% cpu ? ...
Bckground I have a networked application written in C#. my server program has a UI and several communication threads, that read from tcp sockets and display messages on controller UI. Communication with each client is done through a seprate thread. When i recieve some stream of messages from one client , the thread for that client write...
I am reading the Asp.net security documentation on msdn.I come across these tow terms and get really confused. # WindowsIdentity = WindowsIdentity.GetCurrent() which returns the identity of the security context of the currently executing Win32 thread. # Thread = Thread.CurrentPrincipal which returns the principal of the currently ...
I am relatively new to multi-threading and want to execute a background task using a Swingworker thread - the method that is called does not actually return anything but I would like to be notified when it has completed. From all the tutorials that I have seen online about using SwingWorkers are created such as new SwingWorker<String, ...

I am having a problem sometimes with a deadlock when destroying some threads. I've tried to debug the problem but the deadlock never seems to exist when debugging in the IDE, perhaps because of the low speed of the events in the IDE. The problem: The main thread creates several threads when the application starts. The threads are alway...
I have a scenario where I need to search from many binary files (using keys) and combine the results (strings). Until now, I have been doing it in a for loop one file after the other. foreach (string file in FileSources.Keys) { aggregatedDefinitions.Append(DefinitionLookup(txtSearchWord.Text, file)); } Since this operation is very...
Hello, I'm working on an image processing application where I have two threads on top of my main thread: 1 - CameraThread that captures images from the webcam and writes them into a buffer 2 - ImageProcessingThread that takes the latest image from that buffer for filtering. The reason why this is multithreaded is because speed is cri...
In c++, during a class constructor, I started a new thread with 'this' pointer as a parameter which will be used in the thread extensively (say, calling member functions). Is that a bad thing to do? Why and what are the consequences? Edit: my thread start process is at the end of the constructor. Thanks, Gil. ...
What are the rules regarding spawning new threads within other running threads? I have a C# app that handles two basic threads in the background. I recently introduced some heavy duty IO stuff, and I was thinking of setting them off inside threads. Are threads nested within themselves cool? ...
Which way is better for a novice student who has never used boost? When a new standard arrives, the answer will be obvious, but now I have doubts. Pro for boost is that it's much closer to future standard. ...
If I have N STA .NET Threads each performing an independent bulk load operation on a different database using the SQLXMLBulkLoad dll (which requires calling threads to be STA), is it possible for all bulk loads to be happening at the same time, or are they implicitly serialized due to the STA COM configuration? Thanks! ...
