Question

Ok, well I have been at it for a while now and I decided to just use threads. I am making a syntax highlighter but I keep getting terrible performance with the file sizes that it will usually be used for. So I made two forms, the first shows the file in plain text and has a button that says “openincolor” when you click that I start a new thread as such

    private void button1_Click(object sender, EventArgs e)
    {
        ColoringThread colorer = new ColoringThread(this.m_bruteView.Text);
        Thread theThread = new Thread(new ThreadStart(colorer.OpenColorWindow));
        theThread.Start();
    }

    public class ColoringThread
    {
        string text;
        public ColoringThread(string initText)
        {
            text = initText;
        }
        public void OpenColorWindow()
        {
            Form2 form2 = new Form2(text);
            form2.ShowDialog();
        }
    };

I want this form to send back a message each time it has complete say x lines of coloring. Then I will take that and figure out the progress and display it to the user.

How might I go about sending a message, or event(…? can I do that) to my first form to let it know of the others progress?

One very simple way to do this is with BackgroundWorker. It already provides an event to report progress.
