Changing label text « C# Help Forum

Hi all,

I'm new to C# and I'm facing this very annoying problem.. I can't seem to update the text of a label, and when I change the label to a textbox, it only updates it once. I'm now using a textbox, and when I click once, it changes the text. But clicking more than once won't change it anymore. This is my current code:

using System.Windows.Forms;
using System.Drawing;
using System;

class ReversiForm : Form
{
    private TextBox label_zet;

    public int [,] playground = new int[6,6];

    int x = 0;
    int y = 0;
    int turn = 1;

    public ReversiForm()
    {
        this.Text = "Reversi";
        this.BackColor = Color.White;
        this.Size = new Size(600, 600);
        this.Paint += InitializeComponent;
        this.MouseClick += this.mouseClick;
    }

    private void InitializeComponent(object o, PaintEventArgs pea)
    {
        for (int i = 0; i < 7; i++)
        {
            pea.Graphics.DrawLine(Pens.Black, 20 + 50 * i, 200, 20 + 50 * i, 500);
            pea.Graphics.DrawLine(Pens.Black, 20, 200 + 50 * i, 320, 200 + 50 * i);
        }

        this.label_zet = new TextBox();
        this.label_zet.Location = new Point(20, 20);
        this.label_zet.Name = "label";
        this.label_zet.Size = new Size(120, 20);
        this.label_zet.Text = "Player " + turn + " can go now";
        this.Controls.Add(this.label_zet);

        // Stones
        pea.Graphics.FillEllipse(Brushes.Red, 100, 80, 50, 50);
        pea.Graphics.FillEllipse(Brushes.Blue, 100, 140, 50, 50);

        // Draw stones
        for (int i = 0; i < 6; i++)
        {
            for (int t = 0; t < 6; t++)
            {
                if (playground[i, t] == 1)
                {
                    pea.Graphics.FillEllipse(Brushes.Red, 20 + 50 * i, 200 + 50 * t, 50, 50);
                }
                if (playground[i, t] == 2)
                {
                    pea.Graphics.FillEllipse(Brushes.Blue, 20 + 50 * i, 200 + 50 * t, 50, 50);
                }
            }
        }
    }

    public void mouseClick(object o, MouseEventArgs mea)
    {

        x = mea.X;
        y = mea.Y;
        if (x > 20 && x < 320 && y > 200 && y < 500)
        {
            for (int i = 0; i < 6; i++)
            {
                if (x > 20 + 50 * i && x < 20 + 50 * (i + 1))
                {
                    for (int t = 0; t < 6; t++)
                    {
                        if (y > 200 + 50 * t && y < 200 + 50 * (t + 1))
                        {
                            playground[i, t] = turn;
                            if (turn == 1) turn = 2;
                            else turn = 1;
                            this.label_zet.Text = "Player " + turn + " can go now";
                            Invalidate();
                        }
                    }
                }
            }
        }
    }
}

class Reversi
{
    static void Main()
    {
        ReversiForm scherm;
        scherm = new ReversiForm();
        Application.Run(scherm);
    }
}

Changing the textbox into a label will cause the label to not be changed no matter what, not even once. I tried creating a new blank windows forms program with only a label change on the mouseclick event, but this didn't work either. How the hell do you change a label's text? And why does the above code not work properly??

Thanks in advance!
