[2.0] A problem with threads

[proff.hacker]

Hi there,

I use threads to process something and then to display the result in a treeview.

This code works but the problem it does not add until all threads finishes. I want to keep adding as long as I am in FindFolders()

Here is my code:

using System;
using System.Collections.Generic;
using System.ComponentModel;
using System.Data;
using System.Drawing;
using System.Text;
using System.Windows.Forms;
using System.Net;
using System.Net.Sockets;
using System.Threading;
using System.Collections;
 
namespace MyProject
{    
    public partial class Form1 : Form
    {
        private delegate void AddNodeToTreeViewDelegate();
 
 
        public Form1()
        {
            InitializeComponent();           
        }
 
        private void Form1_Load(object sender, EventArgs e)
        {
                   
        }
 
        private void button1_Click(object sender, EventArgs e)
        {
            int j;
 
            for (j = 1; j < 10; j++)
            {
                ThreadStart starter = new ThreadStart(FindFolders);
                Thread t = new Thread(starter);
                t.Start();
            }
        }
     
        private void FindFolders()
        {
            //assume this is the folder name I want to display in the treeview
            string folder_name = "test";
 
            [COLOR=Red]treeView1.Invoke(new AddNodeToTreeViewDelegate(AddNodeToTreeView), new object[] { folder_name });[/COLOR]
 
        } 
 
        private void AddNodeToTreeView(string fname)
        {
            TreeNode p = new TreeNode(fname);
            treeView1.Nodes.Add(p);
        }
 
    }
}
