I have a class project to create a tic tac toe simulations (game is not played by people) where O's and X's automatically generate when the New Game button is clicked. I am having trouble with the code to get the labels to show the output.

Using a 2D array type INT to simulate the game board, it should store a 0 or 1 in each of the 9 elements and produce a O or X. There also needs to be a label to display if X or O wins.

Here is my code so far ( I know there isn't much, I'm completely lost):

public partial class Form1 : Form
{
    public Form1()
    {
        InitializeComponent();
    }

    private void StartButton_Click(object sender, EventArgs e)
    {
        Random rand = new Random();
        const int ROWS = 3;
        const int COLS = 3;

        int[,] gameBoard = new int[ROWS, COLS];

        for (int row = 0; row < ROWS; row++)
        {
            for (int col = 0; col < COLS; col++)
            { gameBoard[row, col]= rand.Next(2); }
        }


    }

    private void ExitButton_Click(object sender, EventArgs e)
    {
        this.Close();
    }
}
}

Win Forms labels get populated unless the current event process finishes completely. If you want to update the labels with X and O while you may use the control property InvokeRequired (boolean) and after assigning the value to label call label.Refresh() function. I will suggest fork a thread on hitting start button and do the for loop -> random.next() inside the thread. Try with these changes. All the Best!!

Dashboard blocks do not support rapid accelerator simulation. Some signals are not available during accelerator mode simulations.

You can try to define a list to store the 2D array value. Then use "foreach" statement to traverse the controls and reset labels' text. Here is a demo you can refer to.

// Define a list to store "O" and "X"
List<string> result = new List<string>();
for (int row = 0; row < ROWS; row++)
{
    for (int col = 0; col < COLS; col++)
    {
        result.Add(gameBoard[row, col] == 0 ? "O" : "X");
    }
}

// Traverse the controls
foreach (var i in Controls)
{
    // Judge if is a label (label1 to label9, the length is 6)
    if (i is Label && ((Label)i).Name.Length == 6)
    {
        // Match the corresponding result
        for (int j = 1; j <= 9; j++)
        {
            // Match by last character of the label
            if (Convert.ToInt32(((Label)i).Name[5].ToString()) == j)
            {
                ((Label)i).Text = result[j - 1];
                break;
            }
        }
    }
}

Comments
  • We don't see a reference to any labels in your code.
  • I know, this is the problem I am trying to solve. labels1-9 are the names, I'm not understanding how to take the randomly generated results and have the labels show an X or O based on what is generated.
  • I'm sorry I'm new to programming, could you provide an example of your explanation? We have not covered what you are referring to in class yet.
  • This does not fit the project criteria, we are required to use label controls in a windows form.
  • Then simply change the control type from a text box to a label. Everything will be the same except a label doesn't have a Multiline (so delete this line).
  • I have already created the form, I am needing it to randomly generate a 0 or 1 and assign a O or X to each label.
  • You would then have to index each label by row and column. I added the 9 Labels into the gameBoard array. So you would need to do the same. Creating the labels dynamically makes changes a lot easier.
