Solved Homework: Question: Hi I need to write a program that accepts an email message in a multi-line area that displays in …

Hi I need to write a program that accepts an email message in a multi-line area that displays in plain text. It’s going to be a program that scans them for 30 spam keywords and keeps a score for each keyword hit, once it reaches a certain score it gets flagged as spam and prompts the user with a pop up window that says “Spam” or “Clear”. The program also needs to be an executable, NOT opened and run from the programming application everytime.

I’ll be asking several questions over the next 5 weeks regarding this and first I’d like to know if someone could show me some examples or show me the simplest form of this? the language is up to me according to the project but I don’t know if I want to do java, c#, or c++. If someone could show me how this is done that’d be great. I’m not sure which language is easiest for it.

This is easily been done by windows application called windows form using


You can use richtextbox to get the user email message.

Evaluate button to chec for the spam messages

If spam exists then you can call for pop up using MessageBox in forms control.

Output will be like

Form1 button1_Click(object sender, EventArgse Enter your email message here Hai pranesh this is free for you spam OK Evaluate

code will be like

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;

namespace spamMessageForms
public partial class Form1 : Form
public Form1()

string[] spamWords = { “offer”,”free”,”offer” };
int[] keyWordHit = new int[3];
string text;

private void button1_Click(object sender, EventArgs e)

string[] arr = (richTextBox1.Text).Split(‘ ‘);

for(int i=0;i<3;i++)
for(int j=0;j<arr.Length;j++)


for(int i=0;i<spamWords.Length;i++)
text += spamWords[i] + ” ” + keyWordHit[i]+”n”;
MessageBox.Show(“Key word hit”+”n” + text);


Designer code:

namespace spamMessageForms
partial class Form1
/// <summary>
/// Required designer variable.
/// </summary>
private System.ComponentModel.IContainer components = null;

/// <summary>
/// Clean up any resources being used.
/// </summary>
/// <param name=”disposing”>true if managed resources should be disposed; otherwise, false.</param>
protected override void Dispose(bool disposing)
if (disposing && (components != null))

#region Windows Form Designer generated code

/// <summary>
/// Required method for Designer support – do not modify
/// the contents of this method with the code editor.
/// </summary>
private void InitializeComponent()
this.label1 = new System.Windows.Forms.Label();
this.richTextBox1 = new System.Windows.Forms.RichTextBox();
this.button1 = new System.Windows.Forms.Button();
// label1
this.label1.AutoSize = true;
this.label1.Location = new System.Drawing.Point(46, 60);
this.label1.Name = “label1”;
this.label1.Size = new System.Drawing.Size(151, 13);
this.label1.TabIndex = 0;
this.label1.Text = “Enter your email message here”;
// richTextBox1
this.richTextBox1.Location = new System.Drawing.Point(49, 108);
this.richTextBox1.Name = “richTextBox1”;
this.richTextBox1.Size = new System.Drawing.Size(256, 136);
this.richTextBox1.TabIndex = 1;
this.richTextBox1.Text = “”;
// button1
this.button1.Location = new System.Drawing.Point(81, 291);
this.button1.Name = “button1”;
this.button1.Size = new System.Drawing.Size(75, 23);
this.button1.TabIndex = 2;
this.button1.Text = “Evaluate”;
this.button1.UseVisualStyleBackColor = true;
this.button1.Click += new System.EventHandler(this.button1_Click);
// Form1
this.AutoScaleDimensions = new System.Drawing.SizeF(6F, 13F);
this.AutoScaleMode = System.Windows.Forms.AutoScaleMode.Font;
this.ClientSize = new System.Drawing.Size(513, 393);
this.Name = “Form1”;
this.Text = “Form1”;



private System.Windows.Forms.Label label1;
private System.Windows.Forms.RichTextBox richTextBox1;
private System.Windows.Forms.Button button1;
