Output.GIF has been attached with this Assignment file. Please observe this file carefully. Your program’s output must be like this output file.

Submission details:

Following files must be submitted in a single zip or rar file.

Code files (Mainwindow.xaml and Mainwindow.xaml.cs)
XML file (named as your (program VUid.xml)
A .gif file which shows the execution of your Application. (For Recording .gif, a software named Screentogif has been uploaded on VULMS in the download section of this course , or you can use any other gif recording tool as well)
You are not required to submit the complete project, only copy these three files from project folder. Please note if you submit doc file you will be awarded 0 marks.

Problem Statement:

The body mass index (BMI) is a measure that uses your height and weight to work out if your weight is healthy. BMI takes into account natural variations in body shape, providing a calculated value for a healthy weight range for a particular height.

If your BMI is:

² below 18.5 – you're in the underweight range

² between 18.5 and 24.9 – you're in the healthy weight range

² between 25 and 29.9 – you're in the overweight range

² 30 or over – you're in the obese range

People who have overweight or obesity, compared to those with healthy weight, are at increased risk for many serious diseases and health conditions. These include:

High blood pressure (hypertension).
Type 2 diabetes.
Coronary heart disease.
Sleep apnoea and breathing problems.
Many types of cancer.
Low quality of life.
Mental illness such as clinical depression, anxiety, and other mental disorders.
Body pain and difficulty with physical functioning.

Maintaining a healthy weight is important for overall health and can help you prevent and control many diseases and conditions.

Keep in view the above discussion, you are required to create a C# WPF application using Visual Studio that calculates the Body Mass Index with the following functional requirements:

Application Interface:

When the application starts, the following screen should be displayed as shown in sample output below:

There should be your OWN VUID in RED color that should be visible at top left corner as shown in the sample output.
There should be two labels of “Height” and “Weight” along with two “text boxes” visible at the center of the screen similar to as shown in the sample output.
There should be a combo box button below the textbox of weight and it should contain two combo box items, “Standard” and “Metric” as shown in the sample output in .GIF file.
After the combo box, there should be a button labeled as “CalculateBMI” and another button labeled as “Clear”, similar to as shown in the sample output.
Below “CalculateBMI” button, there should be two labels, “Result” and “Comments” and in the horizontal space after these labels, there should be two hidden labels which will only be visible if the button “CalculateBMI” is clicked as shown in the sample output in .GIF file.
There should be a text block having text “MY BMI Calculator” rotated with an angle of 8 degrees at the righter space after the text boxes of Height and Weight, similar to as shown in the sample output.
The whole background should be colored of your own choice as shown in sample output. The buttons ”CalculateBMI” and “Clear” should have a background color of your own choice. The background color below your VUID should be different from the whole background color, as shown in the sample output.
You have to use the all the appropriate properties like margin, padding, font sizes, colors, font weights etc to make a similar application as shown in the sample output.

Execution Requirements:

Firstly, without entering any values in any text box, you have to click on the “CalculateBMI” button. So, on clicking the ”CalculateBMI” button, a message should be displayed having the text “please enter the height and weight”.

Then you will enter the height as 71 inches and weight as 150 pounds and click “CalculateBMI” button. After clicking the button, the hidden labels should be visible with correct values and comments. (No other input values will be considered in any case, so be careful and use only the mentioned values)
The Calculated BMI value should be rounded-off to only two fractional digits after the decimal.

Then you will select the combobox item to “Metric” on combo box without changing the values, (using same values as height = 71 CM and weight = 150 KG). On changing the combobox item to “Metric”, the labels of the Height (inches) and Weight (Pounds) should be changed to “Height (CM)” and “Weight (Kg)” as shown in the sample output in .GIF file.
Now, Click the “CalculateBMI” button again, the result and comments should change with correct BMI value and comments.
From the Calculated BMI value, you have to use the appropriate comment as per the following table:

Then you will click the “Clear” button. On clicking it, all the text boxes should be emptied and BMI value and BMI comments should be cleared and should be made hidden, same like they were hidden at the start of the application.

Formulas for Calculating BMI:

For BMI in Standard: Use the following formula in your application for calculating BMI in Standard (I.e. Height in inches and Weight in Pounds)

BMI_in_Standard = 703 x (weight / (height x height));

For BMI in Metric: Use the following formula in your application for calculating BMI in Metric (I.e. Height in CM and Weight in KG)

BMI_in_Metric = 10000 x (weight / (height x height));

Important Note Regarding GIF:

Note: When you run your project, start your .GIF recording only when your output window becomes visible (Do not include any unnecessary part in .GIF file as it wastes time). Moreover, make sure that your .GIF file should not be more than 10 to 15 seconds at maximum.

Best of Luck!

SOLUTION

Program:

using System;

using System.Windows;

using System.Windows.Controls;

using System.Windows.Media;

namespace BMICalculator

public partial class MainWindow : Window

{

// Initialize variables for height, weight, and units

// Set background color of application

// Set background color of header

header.Background = new SolidColorBrush(Color.FromRgb(200, 200, 200));

// Set font size and weight of labels and buttons

buttonClear.Background = new SolidColorBrush(Color.FromRgb(255, 128, 128));

}

private void buttonCalculate_Click(object sender, RoutedEventArgs e)

{

// Check if height and weight values have been entered

}

// Get height and weight values

// Calculate BMI based on units

double bmi = 0;

if (units == "Standard")

{

}

else if (units == "Metric")

{

}

// Round BMI to two decimal places

bmi = Math.Round(bmi, 2);

// Display result and comments

{

// Clear all values and results

}

private void comboBoxUnits_SelectionChanged(object sender, SelectionChangedEventArgs e)

{

// Update units and labels based on combo box selection

units = comboBoxUnits.SelectedItem.ToString();

if (units == "Standard")

{

}
