C# Multithreading

Having more than one CPU core on a single chip makes a system with a processor with two cores operate just like a dual-processor computer, and a system with a processor with four cores operate like a quad-processor computer, so you get much better performance. But if your application does not take advantage of these multiple cores, you may not reap the benefits. OpenMP helps you create multithreaded C++ applications more quickly so the benefits of multithreading can be realized.

I have a singleton class thats used throughout an application.  The app will be multi threaded, each thread will access methods in the singleton class.  Is it best to create an instance of the singleton class at application startup then pass that into each thread, or is it safe to create an instance in each thread separately ?  (I check that no instance currently exists in the singleton class itself, so only 1 instance will ever be invoked)

Hi,

Actually i want to upload a powerpoint file and do the conversion process(convert it to wmv) in the background so that i may not get blocked untill the process gets finished because it's a long process.How can i do that?Is ThreadPool can do that for me ?Any suggestions please ?

Hellw guys, I have the following code

for(int i =0;i<100;i++)

{

foo();

}

this foo function exports pdf crystal reports, how can i start more than one thread to speedup this operation??

Hello,

I have a basic doubt on multithreading. I understand multithreading improves UI response and can be used for long operations. But when talking on asp.net requests and the thread pool, say that the main thread hand over its task to a new thread for the long awaiting operation. But it still uses another thread, so atleast one thread is serving the same request. But how does it improve other requests more fastly though the number of threads consumed are same here.

The Problem:  The line is not rendered consistently, only on the mouseleftup event.

Scenario: 1. Michael clicks the Line button on the toolbar

2. Michael brings the mouse over the ink canvas and clicks the left mouse button

3. While moving the mouse to the right to draw a line, he notices that nothing shows up.

4. On releasing the mouses left button, the line finally renders correctly.

I realize that i most likely need to multithread to accomplish this.

To begin i have  a basic WPF setup, menu bars, borders, toolbars, and i have an ink canvas. The goal of this project is to familiarize myself with image editing and drawing programs. I created a basic Line2D class.

 public class Line2D
 {
  BackgroundWorker worker;

  MainWindow window;
  InkCanvas canvas;
  Line lineToBuild;
  public Line2D(InkCanvas curren
