Question

I am currently taking a beginner’s class in c#. We missed 2 consecutive classes because the teacher couldn’t be there. So we didn’t really see what we needed to do this. He said to just go see on MSDN, but that is usually way too complicated for me. So here is my problem:

I have to create a “Simon Says” program. Here is my current code (sorry for the French variables):

public partial class Form1 : Form
{
    const byte LIMITE = 255;
    const byte LIMITEBOUTON = 5;
    byte[] _abyBouton = new byte[LIMITE];
    Random _rand = new Random();


    public Form1()
    {
        InitializeComponent();
    }

    //Blinks the Button. Works correctly.
    void AnimerBouton(Button btnBouton, Color Cocoleur)
    {
        btnBouton.BackColor = Color.Black;
        btnBouton.ForeColor = Color.White;
        Update();
        System.Threading.Thread.Sleep(500); // C'est inscrit en miliseconde
        btnBouton.BackColor = Cocoleur;
        btnBouton.ForeColor = Color.Black;
        Update();
        System.Threading.Thread.Sleep(500); // C'est inscrit en miliseconde
    }

    private void btnDémarrer_Click(object sender, EventArgs e)
    {
        //Creates an array with the 255 eventual moves.
        for (byte byIndex = 0; byIndex <= LIMITE - 1; byIndex++)
        {
            _abyBouton[byIndex] = (byte)_rand.Next(1, LIMITEBOUTON);
        }

        for (byte byIndex = 0; byIndex <= LIMITE - 1; byIndex++)
        {
            //Takes care of the current progress in the game.
            for (byte byIndex2 = 0; byIndex2 <= byIndex; byIndex2++)
            {
                switch (_abyBouton[byIndex2])
                {
                    case 1:
                        {
                            AnimerBouton(btn1, Color.Green);
                        }
                        break;
                    case 2:
                        {
                            AnimerBouton(btn2, Color.Red);
                        }
                        break;
                    case 3:
                        {
                            AnimerBouton(btn3, Color.Yellow);
                        }
                        break;
                    case 4:
                        {
                            AnimerBouton(btn4, Color.Cyan);
                        }
                        break;
                }
                //Wait to see if the click is correct. No idea how to do this.
            }
        }  
    }
}

So I have to wait for the user to click a button and see if it is the correct one. I looked around and it was talking about events, but I couldn’t grasp what I needed to do. I would appreciate some help on how to do this.

Thanks!

In the designer, on the properties window, click the lightning bolt icon. You will get a list of events for the selected control. Make sure the btnBouton control is selected, and find the Click event in the list. You should see btnDemarrer_Click in the drop down list. Select it. Now when the button is clicked, it should call your btnDemarrer_Click handler.

When you have not already written a handler, you can double-click the event in the list, and it will generate the method skeleton for you automatically. You can also double-click the control itself to generate the default event handler for that control. (In the case of buttons, I think the default event is the click event.)
