You’ve been asked to install a new service called explodingwidgets. After installing the explodingwidgets package, what is the most likely way you would start the service?

I've created a C# Windows form application in Visual stuidos it allows the user to enter information, save that information to a database, then show that information in a datagridview. Everything works fine but the datgridview. It shows that rows have been added but not the text. I can see in my database the reports that have been added so I know its alteast saving the information. I don't know what I'm doing wrong. Please help!

My code:

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;
using System.Data.SqlClient;
using System.Globalization;

namespace Reports
{
public partial class ReportsForm : Form
{
public ReportsForm()
{
InitializeComponent();
}
SqlConnection con = new SqlConnection("Data Source=Blu;Initial Catalog=Reports;Integrated Security=True");
SqlCommand cmd;
private void Submitbtn_Click(object sender, EventArgs e)
{
  

String query = ("INSERT INTO Reports_tbl (EntryDate, ReportText) VALUES ('" + DateTime.Now + "','" + ReportsrichTextBox.Text + "')");
con.Open();
cmd = new SqlCommand(query, con);
cmd.ExecuteNonQuery();
con.Close();

MessageBox.Show("Report Successfully Added");

ReportsrichTextBox.Text = "";

  
}

private void Form1_Load(object sender, EventArgs e)
{

SqlConnection con = new SqlConnection("Data Source=Blu;Initial Catalog=Reports;Integrated Security=True");

con.Open();

SqlDataAdapter da = new SqlDataAdapter("SELECT * FROM Reports_tbl", con);

DataSet ds = new DataSet();

da.Fill(ds,"Reports_tbl");

  
ReportsdataGridView.DataSource = ds.Tables["Reports_tbl"].DefaultView;

  

con.Close();

}
}
}

When browsing to a web page you’ve configured, you are receiving a 403 error. What are two possible causes, and how would they be remedied?

how to solve 403 error issue?

The two standard ACL commands are getfacl and setfacl.

1. What is the difference between them?

2. How can setfacl help achieve security hardening?

For the following exercises, enter the data from each table into MS-Excel and graph the resulting scatter plots (Use a smoothing function). Determine whether the data from the table could represent a function that is linear, exponential, or logarithmic.

Create this C++ program using classes

1. Create a file text file with a string on it

2. Check the frecuency of every letter, number and symbol (including caps)

3. Use heapsort to sort the frecuencys found

4. Use huffman code on the letters, symbols or numbers that have frecuencys

I created the file, and the frecuency part but i'm having trouble with the huffman and heapsort implementation.

Php

2. Use case diagram and the purpose of using a use case diagram.==> analysis

3. use case diagram and data flow diagram==> model the logical concept

4. draw a use case diagram or describe/explain a use case diagram

5. data flow diagram: context diagram + a set of subdiagrams

Question: Write a single SQL query that, for each pair of actors, lists their two actor_ids
and the number of films in which both actors appeared.

DATABASE SCHEMA

CREATE TABLE actor (
actor_id INTEGER,
first_name TEXT,
last_name TEXT);

CREATE TABLE film (
film_id INTEGER,
title TEXT,
description TEXT,
length INTEGER);

CREATE TABLE film_actor (
actor_id INTEGER,
film_id INTEGER);

There is a famous puzzle called the Tower of Hanoi. Code the recursive implementation of it with Python.

Language Javascript

1. Implement Insertion Sort

   1. Non-increasing order,

   2. At least an array of 10 elements.,

   3. You can use a static array.

Describe the A* algorithm. Give one search example: give one graph as example with a heuristic function for each node; give the start node and goal node; apply the A* algorithm on this problem. Show the steps and sequence of nodes visited in order that leads to the optimal solution.

Write a program that translates an English word into a Pig Latin word. Input ONE, and ONLY one, word from the user, and then output its translation to Pig Latin.

The rules for converting a word to Pig Latin follow.

1. The general form for converting a word is to remove the first letter. Then append to the end of the word a hyphen, followed by the first letter that was removed, followed by "ay". For example, "robot" becomes "obot-ray" and "Hello" becomes "ello-Hay".
2. If the word begins with a vowel (an element of "aeiouAEIOU") simply append "-way". For example, "example" becomes "example-way" and "All" becomes "All-way".
3. If the word begins with "th" (or "Th", "tH", or "TH"), remove the prefix and append "-thay" (or "-Thay", "-tHay", or "-THay") to the word. For example, "this" becomes "is-thay" and "The" becomes "e-Thay".

Use at least the REQUIRED METHODS listed below, with the exact same SPELLING for method names and parameters.

Input Specification

Input ONE English word as a string. If multiple words are entered ignore any beyond the first.

Use PRECISELY the format below with the EXACT same SPACING and SPELLING.

Please enter a word ==> 

Output Specification

Output an introductory message, a prompt for the English word, and a translation for the inputted word.

Use PRECISELY the format below with the EXACT same SPACING and SPELLING. The output below assumes the user entered "Hunger".

This program will convert an English word into Pig Latin.

Please enter a word ==> Hunger

"Hunger"
  in Pig Latin is
"unger-Hay"

Required Methods

// Prompt and read a word to translate
public static String  readWord (Scanner console)

// Convert a word to Pig Latin and return it
public static String  convertWord (String englishWord)

// Return true if "c" is a vowel, false otherwise.
// Handle both lowercase and uppercase letters.
public static boolean isVowel (char c)

// Print result of translation
public static void printResult (String englishWord, String pigLatinWord)

Hints

BEFORE you start coding, think about which methods each method will call. Which methods should "main" call? Create a diagram which shows the calling relationships.

There are many useful String methods listed HERE. You may find startsWith and charAt helpful.

Style

Write comments

• Choose mnemonic, meaningful variable names (e.g. balance, interestRate)
• Indent consistently (Ctrl+Shift+F will format your code)
• Remember the comment block at the top of your program

Write a C++ script to perform the following:

a.) Ask a user to enter 2 real numbers.
b.) Save the user response as a variable a and b.
c.) Display if the numbers are even or odd.
d.) Check if the number a belongs in the interval D = [10, 99], display the output as "a is between 10 and 99" or "a is not between 10 and 99".
e.) Check if the number b belongs in the interval E = [0, 50], display the output as "b is between 0 and 50" or "b is not between 0 and 50".

Digital Forensics, At least 200 words for each question

1/ Research a network attack (DDoS, Man-in-the-Middle, IP Spoofing, etc.) and explain it in further detail.

2/ Discuss ways that forensic examiners have been able to identify and analyze these attacks.

3/ Find an attack , where an examiner was able to successfully identify the attacker, and explain techniques used to do so.
