Threading VS 2005

OK, I'm using VS 2005 and I am having a difficult Time in creating and starting a thread. Below is my code that should start a thread, but the last output on the debugger says "A first chance exception of type 'System.IndexOutOfRangeException' occurred in FTPClient.exe" and the process doesn't kick off.

Code:

---

private void Form1_Load(object sender, EventArgs e)
{
      Thread newThread = new Thread(LoadConfig);
      newThread.Start();
}

---

The below code is what I wrote in C# VS 2003 and it works.

Code:

---

Thread newThread =  new Thread(new ThreadStart(Go));
newThread.Start();

---

Any answers or ideas are greatly appreciated.

Thanks,
Josh

Hmm... I don't know threads outside Boost::threads... But that new statement is plain and vanilla C++:

Code:

---

Thread* newThread = new Thread(LoadConfig);

---

If that alone will solve your problem, I don't know. But you need a pointer to allocate memory.

Throws a lot of errors when I use the pointer.
Error 1 Cannot take the address of, get the size of, or declare a pointer to a managed type ('System.Threading.Thread')
Error 2 Pointers and fixed size buffers may only be used in an unsafe context
Error 3 Cannot implicitly convert type 'System.Threading.Thread' to 'System.Threading.Thread*'
Error 4 Pointers and fixed size buffers may only be used in an unsafe context
Error 5 Operator '.' cannot be applied to operand of type 'System.Threading.Thread*'

Thanks,

More errors doesn't mean necessarily it's more wrong :)
I had it happen to me before.

However, I can see you are using managed C++. My bad. Forgot about this forum theme.

It's thread^, I reckon. Not *. The last error message has to do with the need to use the -> operator when accessing members of of a pointer to object. I don't know if that syntax remains in managed C++.

Anyways, since this is managed C++... I'm kind out of my environment. So, over and out. Hope that at least leads you in the right direction :)

you can try something like this ...

Code:

---


            Thread newThread = new Thread(new ThreadStart(doSomething));
            newThread.Start();

---

Mario, this is C#, not Managed C++. You stumbled into the C# forum ;)

Do you have a stack trace with that exception?

oh sorry i didnt see this ...

however ... seems you might have an array out of index in "LoadConfig" or elsewhere ...

you can use the "unsafe" keyword to use pointers ...

Code:

---


    class Program
    {
            unsafe public void test()
            {
                int* pointer;
                int digit = 100;
                pointer = &digit;
                Console.WriteLine("{0}", pointer);
            }

        static void Main(string[] args)
        {
            test();
        }
    }

just make sure you "allow" it in your complier options :)

That is not the point, however. Unsafe code is, well, unsafe, and underlies many restrictions, as do programs that use it.

ya well, a comment was made about pointers and i just simply made a reply, and "unsafe" code was added to c# for a reason like performance, flexibility and direct memory management. I think c# would be a weaker language without them.
