Question

C#

What to submit:

One zip file named Ass3.zip

This zip must contain one VS 2017 solution named Ass3, which contains one C# Windows Forms App project also named Ass3 and the project contains a default form, Form1.cs and Program.cs.

No change should be made in Program.cs, but your Form1 must be designed and implemented to satisfy the following requirements.

**Do not submit only a single file of the solution or project. The whole solution folder of VS 2017 must be zipped and submitted for grading.

Requirements:

1. Use VS 2017 to create a C# Windows Forms App project whose solution and project are named Ass3. When all requirements below are finished and tested, zip the entire solution as Ass3.zip and upload it for grading.
2. Use the same Functional Requirement as described in Assignment 2 with the changes below.
3. Except the Form1 class given by Visual Studio, no other classes need to be defined. That is, the program you did in Assignment 2, including data and methods of the two classes should be "transplanted" in the Form1 class of this Ass3 project.
4. All input and output should be done within Form1 and visual controls (e.g., textboxes, labels, buttons, etc.) on the form. That is, no console is used--no more command line I/O and no display in the Command Prompt.
5. Specifically, the two initial integers and each guess should be entered in a corresponding textbox (i.e., three textboxes in total) and the error message "You must enter a number between ... and ...!" will be displayed by a label in red. A second label should be used to display in blue the hint "Higher...", "Lower...", and "You win!". Finally, let the ending message "----End of Game----" be displayed in the form title (in black since title color cannot be changed).
6. Set the font size of all visual controls to be 18 points.
7. Add a button showing 'Generate Secrete Number' to create a secrete number every time it is clicked. Because this button can be clicked at any time, there might be an error or hint displayed from the previous play, this button should also erase both labels to empty and reset the form title to 'Form1' when clicked.
8. To accept a guess, a second button showing 'Guess' should be added on the form. Each time when it is clicked, it first erases the labels from their previous display and then show the error and/or hint message, depending on the guess entered.
9. Place each visual control in Form1 so they look like the form shown in the demo program attached below.
10. Same as in Assignment 2, we assume there are always two valid input integers entered to define the range of the random secrete number, and an integer is always entered as the guess value. That means there is no need to validate all three input integers except the guess value could still be out of the range, which explains (in item 5 above) why an error message needs to be displayed.

Answer 1

A new windows form application using visual studio with name "Ass3" is created which contains below details.

1.Form1.cs[Design]

2.Form1.cs

//namespace
using System;
using System.Drawing;
using System.Windows.Forms;
//application namespace
namespace Ass3
{
public partial class Form1 : Form
{
//secrete number variable
int secNumber = 0;
//creating object of Random class
Random random = new Random();
public Form1()
{
InitializeComponent();
}
//secrete button click
private void btnSecrete_Click(object sender, EventArgs e)
{
lblDetails.Text = "";//clear label
lblSample.Text = "";//clear label
this.Text = "Form1";//set form title
//generate number between lower and higher number
secNumber = random.Next(int.Parse(txtLower.Text), int.Parse(txtHigher.Text));
}
//Guess Button click
private void btnGuess_Click(object sender, EventArgs e)
{
lblDetails.Text = "";//clear label
lblSample.Text = "";//clear label
int guess = int.Parse(txtGuessNumber.Text);//guess entered
//checking guess number
if (guess < int.Parse(txtLower.Text) || guess> int.Parse(txtHigher.Text))
{
//show error if guess is not in the range
lblDetails.Text= "You must enter a number between "+ txtLower.Text + " and "+txtHigher.Text+"!";
lblDetails.ForeColor = Color.Red;//set label color
}
else
{
//checking guess with generated random number
if (guess < secNumber)
{
//if guess is lower than generated random number then display message
lblSample.Text = "Lower...";
lblSample.ForeColor = Color.Blue;//set color
}
else if (guess == secNumber)
{
//if guess is equal to secreteNumber then display message
lblSample.Text = "You win!";
lblSample.ForeColor = Color.Blue;//set color
//set form title to
this.Text = "----End of Game----";
}
else if (guess> secNumber)
{
//if guess is higher than generated random number then display message
lblSample.Text = "Higher...";
lblSample.ForeColor = Color.Blue;//set color
}
  

}
}
}
}
====================

Screen 1:When number is not in the range

Screen 2:Screen when guess is lower then the generated number

Screen 3:Screen when guess is higher then the generated number

Screen 4:Screen when guess is equal to generated number
