    <p>Just so everyone knows I have literally just started writing C#, and this is practice.</p> <p>I found a GuessTheNumberGame code on the internet and have been trying to improve the basic game so that feedback is given, and the user can change the numbers. I had the program working but wanted to put the 'NumberChange' module separate from the 'Code' Method.</p> <p>I have made a Main() Method inside of my 'GuessTheNumberGame' with executes the 'Code' method. The thing is when I go to change the number range the 'NumberChange' module won't change the values of 'Public Static int from' or 'Public static int to'; and because of this the range of the numbers remains the same.</p> <p>Code below:</p> <pre><code>using System; namespace GuessThatNumber { class GuessTheNumberGame { static void Main() { Code(from, to, new_range); } public static int new_range = 0; public static int from = 1; public static int to = 10; static void Code(int from, int to, int new_range) { //int from = 1; // The range the user will guess from. //int to = 10; //The range the user will guess to. int guessedNumber; //This will hold the value that the user guessed. int Counter = 0; //Counter is used to count the number of guesses the user makes. int selection = 0; //This value is for the selection at the start of the program //int new_range = 0; bool exit = false; while (exit == false) { Console.WriteLine("What would you like to do?"); Console.WriteLine("1: Alter the range of guessed numbers? The range is currently from {0} to {1}.", from, to); Console.WriteLine("2: Try to guess the number?"); Console.WriteLine("3: Exit the program?"); Console.WriteLine("Please enter a number:"); if (int.TryParse(Console.ReadLine(), out selection)) { if (selection == 2) { int randomNumber = new Random().Next(from, to); //Generates a random number between the (from, to) variables. Console.Write("The number is between {0} and {1}. ", from, to); while (true) { Console.Write("Make a guess: "); if (int.TryParse(Console.ReadLine(), out guessedNumber)) { if (guessedNumber == randomNumber) { Console.WriteLine("You guessed the right number!"); if (Counter &lt; 2) { Console.WriteLine("You guessed the number in only 1 turn! Amazing!"); Console.WriteLine(" "); } else { Console.WriteLine("You guessed " + Counter + " times."); Console.WriteLine(" "); } break; } else { Console.WriteLine("Your guess was too {0}.", (guessedNumber &gt; randomNumber) ? "high" : "low"); Counter = Counter + 1; } } else { Console.WriteLine("Input was not an integer."); } } //Console.WriteLine(); //Console.WriteLine("Press any key to exit."); //Console.ReadKey(); } else if (selection == 1) { NumberChange(from, to, new_range); } else { exit = true; } } } } static int NumberChange(int from, int to, int new_range) { Console.WriteLine("Please enter the number that the guess will start from."); int.TryParse(Console.ReadLine(), out new_range); from = new_range; Console.WriteLine("Now enter the number that the guess will go to."); int.TryParse(Console.ReadLine(), out new_range); to = new_range; return new_range; } } } </code></pre>

    1. COIt is not a "void". It is a **function**. The return type of the function is `void`, but it is not correct, ever, to refer to a function definition as an instance of its return type.

A row detail

Detail views are divided into sections. All the information in the data section comes from columns in the selected row. The other sections display data from other, related rows.

Related data can be related in a to-one or a to-many fashion. Captions of data related in a to-many fashion link to a list view showing a filtered view of the table.

Try moving around until you find a non-empty to-many entry and click on the label to get to one. You can move back to the root by clicking on the database name in the header.
