如何使用按钮更改表单的背景颜色

Question

So I am in VB and I'm trying to create some buttons so when you click them, it changes the background of my form. Instead of this happening, the background of the button changes. How do I fix this?

        public Form1()
        {
            InitializeComponent();
        }

        private void Form1_Load(object sender, EventArgs e)
        {

        }

        private void button1_Click(object sender, EventArgs e)
        {
            this.button1.BackColor = System.Drawing.Color.Black;
        }

        private void button2_Click(object sender, EventArgs e)
        {
            this.button2.BackColor = System.Drawing.Color.Green;
        }

        private void button3_Click(object sender, EventArgs e)
        {
            this.button3.BackColor = System.Drawing.Color.Red;
        }

        private void button4_Click(object sender, EventArgs e)
        {
            this.button4.BackColor = System.Drawing.Color.Blue;
        }
    }
}

Answer 1

You can try the following code with just a single button press to achieve your requirement:

Private Sub RandomColor()
        Dim rand As New Random
        BackColor = Color.FromArgb(rand.Next(0, 256), rand.Next(0, 256), rand.Next(0,
            256))
End Sub

Private Sub Button1_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Button1.Click
        RandomColor()
End Sub

Hope it helps you.
