C# pomoc oko timera i progressbara

Pravim jedan program koji bi trebao da radi jednostavnu stvar...trebalo bi da uradi sledece...nakon sto progressbar zavrsi do kraja loading..da se u textboxu1 ispise "nesto"....evo koda koji je do sad napisan:

private const Int32 PROGRESS_INTERVAL = 5000;
private const Int32 TIMEOUT = 60000;

private System.Threading.Timer m_tmrProgress, m_tmrTimeout;

private void button1_Click(object sender, EventArgs e)
{
    progressBar1.Maximum = TIMEOUT / PROGRESS_INTERVAL;

    m_tmrProgress = new System.Threading.Timer(this.ProgressCallback, null, 1, PROGRESS_INTERVAL);
    m_tmrTimeout = new System.Threading.Timer(this.TimeoutCallback, null, TIMEOUT, 0);

}

private delegate void IncrementTimerDelegate(int i);
private void IncrementTimer(int i)
{
    progressBar1.Increment(i);
}

private void ProgressCallback(object state)
{
    this.Invoke(new IncrementTimerDelegate(this.IncrementTimer), new object[] { 1 });
}

private void TimeoutCallback(object state)
{
    m_tmrProgress.Dispose();
    m_tmrTimeout.Dispose();
}

Evo napisao sam ti ogledni primjer u kojem je to jednostavnije rješeno i bolje (Timer ti baš i nije najbolja metodika, izbjegavaj timer-e)

        private const int goToNumber = 200;
        System.Threading.Thread loadThread;

        public Form1()
        {
            loadThread = new System.Threading.Thread(new System.Threading.ThreadStart( this.loadSomething));

        }

        private void button1_Click(object sender, System.EventArgs e)
        {
            if (!loadThread.IsAlive)
            {
                loadThread.Start();
            }
        }

        public void loadSomething()
        {
            int loadingCurrent = 0;
            progressBar1.Maximum = goToNumber;
            progressBar1.Minimum = loadingCurrent;
            while (loadingCurrent < goToNumber)
            {
                progressBar1.Value = loadingCurrent;
                loadingCurrent++;
                System.Threading.Thread.Sleep(100);
            }
        }

Pa probaj tako...

ubaciš ga iza while petlje? tj. na kraj load funkcije...

progress bar je tu samo kozmetički efekt, a ne nešto prema čemu ćeš se orjentirat...
