How do I Create a project named DayNight. Include a Form that contains two Buttons, one labeled Day and one labeled Night. Add a Label telling the user to click a button. When the user clicks Day, change the BackColor of the Form to Yellow; when the user clicks Night, change the BackColor of the Form to DarkBlue in C#?
Solution
Good Wishes,
First let me give the code:
using System;
using System.Drawing;
using System.Windows.Forms;
namespace DayNight
{
public partial class Form1 : Form
{
public Form1()
{
InitializeComponent();
/*Button button1=new Buton();
Button button2=new Buton();*/
}
private void Form1_Load(object sender, EventArgs e)
{
label1.Text = \"Please click on a button to see the background color change\";
button1.Text = \"Day\";
button2.Text = \"Night\";
}
private void button1_Click(object sender, EventArgs e)
{
this.BackColor = System.Drawing.Color.Yellow;
}
private void button2_Click(object sender, EventArgs e)
{
this.BackColor = System.Drawing.Color.DarkBlue;
}
}
}
Explaination:
Initially i created a project named DayNight
namespace DayNight
{}
Then I created a form
public partial class Form1 : Form
Then I created a constructor
public Form1()
{
InitializeComponent();
/*Button button1=new Buton();
Button button2=new Buton();*/
}
Then i wrote a function to load the form
private void Form1_Load(object sender, EventArgs e)
{
label1.Text = \"Please click on a button to see the background color change\";
button1.Text = \"Day\";
button2.Text = \"Night\";
}
In this function I created a label to indicate the user to click on a button
label1.Text = \"Please click on a button to see the background color change\";
Next I labelled the two buttons as one \"Day\" and the other \"Night\"
button1.Text = \"Day\";
button2.Text = \"Night\";
Then I created a fuction to handle the button1 on click event
private void button1_Click(object sender, EventArgs e)
{
this.BackColor = System.Drawing.Color.Yellow;
}
here when button1 is clicked the background color of the form changes to Yelow in color.
Then I created a fuction to handle the button2 on click event
private void button2_Click(object sender, EventArgs e)
{
this.BackColor = System.Drawing.Color.Dark Blue;
}
here when button2 is clicked the background color of the form changes to Dark Blue in color.
Hope this is clear.
