Question

I’m doing a tic tac toe game and I am trying to add a combo box that will change the applications background based on what the person selects right now I have summer, spring, fall, winter and the images are in the bin/debug folder how can I get this to work I don’t know where to start and the tutorials are a bit confusing. Could you please help me

It isn’t exactly clear what you are asking. Assuming you’ve got bitmap files with names like “spring.png” etc in your bin\Debug folder, this ought to work:

public partial class Form1 : Form {
    public Form1() {
        InitializeComponent();
        comboBox1.Items.AddRange(new string[] { "Spring", "Summer", "Fall", "Winter" });
        comboBox1.SelectedIndexChanged += comboBox1_SelectedIndexChanged;
    }

    private void comboBox1_SelectedIndexChanged(object sender, EventArgs e) {
        string folder = Application.StartupPath;
        string theme = (string)comboBox1.Items[comboBox1.SelectedIndex];
        string path = System.IO.Path.Combine(folder, theme + ".png");
        Image newImage = new Bitmap(path);
        if (this.BackgroundImage != null) this.BackgroundImage.Dispose();
        this.BackgroundImage = newImage;
    }
}
