• That would be close to impossible to know, since the number of beats depends on your pulse. And your pulse varies over time (depends on physical activity, general health, stress and a bunch of other factors) and can differ a lot from one person to another.

Sure you could calculate som kind of approximation based on some average pulse, but it would just be a wild guess at best.

• The heart beat will vary from person to person and year after year. So you can't get an exact figure.

For developing this based on some fixed figure, say 80 beats in a minutes.

Start by creating a Windows Form application.

1. Add a date picker control and a button as shown below

2. Update the calculate click event as follows

```private void button1_Click(object sender, EventArgs e)
{
DateTime birthDate = dateTimePicker1.Value;
TimeSpan diff = DateTime.Now.Subtract(birthDate);
double beats = diff.TotalMinutes * 80;
MessageBox.Show("HearBeat Approximates to : " + beats.ToString(), "HearBeat", MessageBoxButtons.OK, MessageBoxIcon.Information);
}```

• Other than needing to change total to a string when outputting the result the code will compile, but I'm not sure what you are putting in the TextBoxes.

textBox4.Text = total.ToString();

As mentioned earlier, a DateTimePicker would be suitable to input a date.  Or you can use a regular TextBox and parse the text using DateTime.Parse().  Once you have a DateTime object it is very easy to find the number of Years, Days, Seconds and so on by simply subtracting one from the other.

TimeSpan difference = DateTime.Now - enteredDate;

int numberOfDays = difference.Days;

• You have clear idea of the requirements then Why struggling on where to start. If you want the complete code for this on how to do it put a post.

I'll help you. Without knowing what kind of a help you need if I spend time on this, it'll be waste of time for both of us.

• Hi,

Well, you would need input fields, and some way to display the result.  A button press can calculate the result.

I thought of displaying it in a message box. Just giving some idea about how he can go ahead.

• at the moment all i have done is a simple form of 4 text boxs an a button with this code

sing

System;

using

System.Collections.Generic;

using

System.ComponentModel;

using

System.Data;

using

System.Drawing;

using

System.Text;

using

System.Windows.Forms;

namespace

WindowsApplication1

{

public partial class Form1 : Form

{

public Form1()

{

InitializeComponent();

}

int day = 0;

int dayBeats;

int month = 0;

int monthBeats = 0;

int year = 0;

int yearBeats = 0;

int total = 0;

private void button1_Click(object sender, EventArgs e)

{

day =

int.Parse(textBox1.Text);

// the number of days

dayBeats = (day - 16 * 168000);

month =

int.Parse(textBox2.Text);

monthBeats = (month - 9 * 3024000);

year =

int.Parse(textBox3.Text);

yearBeats = (2032 - year * 36288000);

total = (dayBeats + monthBeats + yearBeats);

textBox4.Text = total;

}

}

}

p.s am bit of a novice just to point out

• Are you getting any error? Able to compile the code?
