Question

Create a C# Form with a textbox and a button. The box is for a user to enter a number of seconds. And when the user clicks the button, the program displays the equivalent number of hours, minutes and seconds using a MessageBox. Show method. If the seconds entered is less than 60, your program should only display the seconds; if the seconds is a least 60 and less than 3600, your program should display minutes and seconds; if the second is at least 3600, your program should display hours, minutes and seconds. Use the following data to test your program: 47 seconds: 47 seconds (don’t show 0 hour and 0 minute) 645 seconds: 10 minutes, 45 seconds (don’t show 0 hour) 7565 seconds: 2 hours, 6 minutes, 5 seconds Requirements: 1. Input validation: The number of seconds cannot exceed 86400. You must use textbox’s Validating event to do the validation

Answer 1

Dear Student ,

As per the requirement submitted above , kindly find the below solution.

Here a new Windows Forms Application in C# is created using Visual Studio 2017 with name "TimeApplication".This application contains a form with name "Form1.cs".Below are the files associated with form1.

1.Form1.cs[Design]

2.Form1.cs

//namespace
using System;
using System.Collections.Generic;
using System.ComponentModel;
using System.Data;
using System.Drawing;
using System.Linq;
using System.Text;
using System.Threading.Tasks;
using System.Windows.Forms;
//application namespace
namespace TimeApplication
{
public partial class Form1 : Form
{
public Form1()
{
InitializeComponent();
}
//time button click
private void btnTime_Click(object sender, EventArgs e)
{
//desclring variable to store seconds
int seconds=int.Parse(txtSeconds.Text);
//checking seconds
if(seconds<60)
{
//display only seconds
MessageBox.Show(seconds + " seconds","Time");
}
else if(seconds>=60 && seconds<3600)
{
//if seconds are 60 to 3600
int min = seconds / 60;
int sec = seconds % 60;
//display miutes and seconds in the messagebox
MessageBox.Show(min + " minutes ," + sec + " seconds", "Time");
}
else if(seconds>=3600)
{
//if seconds are greater than or equal to 3600
int hours = seconds / 3600;//finding hours
seconds = seconds % 3600;
int min = seconds / 60;//finding minutes
seconds = seconds % 60;
//display hours,minutes and seconds
MessageBox.Show(hours + " hours," + min + " minutes," + seconds + " seconds", "Time");
}
}
//validating event of the textbox
private void txtSeconds_Validating(object sender, CancelEventArgs e)
{
//checking seconds should not exceed 86400
if (int.Parse(txtSeconds.Text) > 86400)
{
//if seconds are greater than 86400
MessageBox.Show("Enter seconds less than 86400", "Time");
}
}
}
}

======================================================

Output : Run application using F5 and will get the screen as shown below

Screen 1 :

Screen 2:Screen showing seconds

Screen 3:Screen showing seconds and minutes

Screen 4:Screen showing seconds ,minutes and hours

Screen 5:Screen when seconds exceeds 86400
