question in c# multi-threading

[RiskyHunter]

Hi all;

I hope u don't ignore my question this time because whenever I ask questions
here nobody answer them T_T. what's the problem is they are too trivial in away
you don’t even want to answer them?? I really don’t know O_o

Anyway this is my problem;

i have a method which generate the user location;

and i wanna use multi threading to get the position of the user concurrently;

Hashtable ht = new Hashtable();

public void XYZ(List<User> p2)
{
for (int i = 0; i < p2.Count();i++ )
{
Thread t = new Thread(userLocation);
int g = p2[i].getGPSID();
t.Start(g);
}

}

public static void userLocation(object gpsid)
{

// generate the position x and y
ht.Add(gpsid, new Location(x, y));

}

i have read a tutorial about multithreading however am not sure if this is the right
way so that all the new created thread will work concurrently

thanks a lot;

If you're just starting with multithreading I suggest that you use the BackgroundWorker - it's simple to understand and easily implemented. You have it in your toolbox/components.
Implement the DoWork event for it. You can pass arguments you need for it to work like this:

myBackgroundWorker.RunWorkerAsync(myArguments);
...

private void myBackgroundWorker_DoWork(object sender, DoWorkEventArgs e)
{
//here you can cast e.Argument to the type of myArguments and work with it.
}

If you need to do something upon the completion implement the RunWorkerCompleted. This event is raised when the DoWork event handler returns. (more info: msdn help on RunWorkerCompleted

veljkoz thanks 4 ur reply;

however, i really wanna knew whats the different (in term of functionalities) between
the two ways, the way that i implement the thread and the backgroundWorker
which way is much better;

thanks a lot;
