long loop problem

hello guys,

i'm writing a windows application. once the user click on a button, i will run a loop. the loop will take a long time to finish, and during the execution the program looks like dead. i want my application can still response to user input, what do i do?

thanks.

plus, i saw a warning every time i run the program saying that the program doesn't respond. everything is actually ok, i just click continue, everything will be fine. but the warning is still annoying. how should i deal with that.

the warning shows up when i debug the code. i don't know if it will still show up if i compile it as a release mode.

This is quite simple,
just use the BackgroundWorker Thread, or the "usual" threads as follows:

Code:

---

using System;
using System.Text;
using System.Windows.Forms;

using System.Threading;

namespace WindowsApplication1
{
    public partial class Form1 : Form
    {
        public Form1()
        {
            InitializeComponent();
        }


        private void MyThread()
        {
            // do something loop-ish here
        }

        private void button1_Click(object sender, EventArgs e)
        {
            Thread thread = new Thread(new ThreadStart(MyThread));
            thread.Start();
        }

    }
}

---

The thread runs independently and does not freeze your GUI.
