Checkers_03

Adam

Thanks for Save() and Load() methods. They work good but when I save somethink and Load it, it is loaded after press some key... and How would you do method StepBack ?? I didnt tell u before because I dont know about it:D ok so I will just do Binary seialization, and could I later do also Events?? because it all will be also for Windows Form. Can you tell me about some good tutorial for Windows Form after which I ll be able to remake dll also for WF?? And what about exceptions??. The rest I wont do.Below is whole code. You already can play checker, I just must finish a couple of details. THX!

Know the answer? Post it — somebody with the same question will find it here.

OK thank you:)
Vulpes15y ago
As regards future projects, now you've made a start with Windows Forms I'd create a more traditional application (using the mouse rather than the keyboard) - something you're interested in, it doesn't have to be a game - to consolidate what you've already learnt.

After that you've got a choice - perhaps Web programming or smartphone programming. The latter is very popular just now :)

Also, if you don't already have a good reference book on C#, I'd buy one (see http://www.amazon.com/4-0-Complete-Reference-Herbert-Schildt/dp/007174116X) and read it from cover to cover. Once you know the language really well, you'll be able to do virtually any kind of programming with it and you'll have something to turn to if you get stuck.
Vulpes15y ago
Good luck, I hope you get a decent mark for it :)
Adam15y ago
So thats finally end:)Thank you very much for your effort

I've no idea on the first point as the last version I have throws an exception when I try to move off the board in either the down or right direction!

However, if MoveUp works but MoveDown doesn't, then I'd put the code for the two methods side by side and go through both methods line by line until you find the problem as the code for the two methods should be complimentary.

It's not possible to change the border color of the standard picturebox. What you should do instead is to use different images for highlighted squares - just use the same images as for non-highlighted squares but with a different background color.

Regarding the third point:

Add this class to the dll within the same namespace as the SaveBoard class:

public class Move
{
public char[,] Area = new char[X, Y];
public bool pick;
public bool dir;
public bool dir3;
public bool dir4;
public bool dir5;
public bool dir6;
public bool queen;
public bool que;
public bool que2;
public bool que3;
public bool que4;
public bool que5;
public bool que6;
public bool arr;
public bool again;
public bool player;
public int xpos;
public int ypos;
}

Add the following field to the SaveBoard class (just after ypos):

private Stack moves = new Stack();

Create a new method in the SaveBoard class:

private void SaveMove();
{
Move m = new Move();
m.Area = Area;
m.pick = pick;
m.dir = dir; // etc down to ypos
moves.Push(m);
}

Call the SaveMove() method before every new move.

Now add a MoveBack Method to the SaveBoard class:

public void MoveBack()
{
if (moves.Count > 0)
{
Move m = moves.Pop();
Area = m.Area;
pick = m.Pick;
dir = m.dir;
}
return Area;

and call that from within SaveBoard whenever you want to move back. Area etc. should then be passed back to the exe in the normal way so that the board can be redrawn.

I dont understand, when e.g Symbol is on position xpos = 7, so its penultimate row and I press Down arrow for choose move, it moves to last row and then when Iam pressing Down arrow it doesnt react. It is only problem with this last row. Can I also add colour to border of picturebox when its just 3D now? And I dont know how to component your code about stack to code to moveback, can u please do it as last thing because tomorrow I have to send it to my prof.

using System;
using System.Collections;
using System.Collections.Generic;

class Test
{
static void Main()
{
Stack s = new Stack();
s.Push(1);
s.Push(2);
s.Push(3);
// do foreach using the default enumerator
foreach(int i in s) Console.Write("{0} ", i); // 3 2 1
Console.WriteLine();
// wrap the stack in a StackWrapper object
var sw = new StackWrapper(s);
// iterate the StackWrapper
foreach(int i in sw) Console.Write("{0} ", i); // 1 2 3
Console.ReadKey();
}
}

}

public IEnumerator GetEnumerator()
{
T[] elements = stack.ToArray();
for(int i = elements.Length - 1; i >= 0; i--) yield return elements[i];

IEnumerator IEnumerable.GetEnumerator() // need to implement non-generic IEnumerable as well

I am lost. So I must creat my own stack or not?? When I put this Stack moves = new Stack(); into Main method
it throws error that it could not find T type, so maybe I shoud use som 'using'. Pleace correct me if I understand it wrong. So I ll creat Stack in Main method and in form. then I moves.Push(Area) only when choose is false or true ?? because choose is changing just when I need put Area into stack. Or should I do some method like:
public char[,] Undo()
        {
                for (int i = 0; i < X; i++)
                {
                    for (int y = 0; y < Y; y++)
                    {
                        Area[i, y] = Area3[i, y];
                    }
                }
            return Area3;
        }

and Push Area3 into stack?? then what should I do when Stack is full? I d clear all stack and start again.
About iteratr, why should I convert stack from 1,2,3 to 3,2,1?? I want move only one step back So if I put moves into stack 1,2,3, the last move will still be on the top. And I dont know different between iterator and foreach. Can you show me please how could it look?I dont know how transfer my idea to code:(
Vulpes15y ago
For information on iterators, see here (http://msdn.microsoft.com/en-us/library/dscyy5s0.aspx) and also here (http://www.blackwasp.co.uk/CSharpIterators.aspx).

For generics and generic collections, see here (http://msdn.microsoft.com/en-us/library/512aeb7t.aspx), here (http://msdn.microsoft.com/en-us/library/ms172181.aspx) and also here (http://en.csharp-online.net/Understanding_Generics%E2%80%94Creating_a_Custom_Generic_Collection).

I'd also search the articles on this site as there are sure to be some good ones on these topics.
Adam15y ago
Ok can u please give some good threads about iterators, bcs I ve never used it, and also generic col.
Vulpes15y ago
Well, Stack is a generic type and you could use that to implement your 'undo' functionality.

Suppose you create a Move class in the dll which contains all the information needed to recreate a move. You can then create a Stack of Moves as follows:

Stack moves = new Stack();

Each time a move is made you then create a Move object, 'move' say, and push it onto the stack:

moves.Push(move);

If you then want to 'move back' you need to pop the last Move object from the stack after making sure that there are still Moves left on the stack:

Move prevMove = null;

if (moves.Count > 0)
{
prevMove = move.Pop();
}

if (preMove != null)
{
// recreate previous move
}

Clearly, you can go back as many moves as you like with this approach.

The Stack class implements IEnumerable and therefore already has an enumerator. You could iterate through the stack elements to produce a display of previous moves but you wouldn't be using a custom iterator, you'd be using the one that's already built into the class.

To write a custom iterator you either need to create a custom collection class or find a novel way of iterating through an existing collection.

The Stack class's default enumerator iterates through the elements in reverse order of being added. So, if you had a Stack and pushed 1 and then 2 onto the stack, they'd be enumerated in the order 2, 1. You could write a custom iterator which iterated in the opposite direction from which you could display a list of all a player's moves from the beginning (i.e. 1, 2 in the example) - whatever use that would be - but it's a possibility if you can't think of anything better.

I still think that your best hope of using a custom exception class would be when loading/saving a game and, of course, I've already shown how that could be done for the console application.
Adam15y ago
So i should use there own exceptions, generic collections and iterator, but they shouldnt be used on some important parts of project, I should use them in order they could see that I can use them. Dont u know about some easy use of them? E.g. when is MoveBack somebody has told me that I can use generic colections and iterator here. Generic collections for number of figurines of both players ( dont understand ) or where is Undo to I should use some generic data type, and put it into Enumerable and it will be as iterator. I dont understand these advices. Can u please tell me your opinion and how can I make Stack for undo??? thx
Vulpes15y ago
The most likely reason why it's not responding to keystrokes is because you've simply copied in the code for the Form1_KeyDown eventhandler and so the event isn't wired up.

When adding events to forms and controls in Visual Studio, it's best to always do so from the Properties box. Click on the 'lightning bolt' symbol to examine events rather than properties, find the event you need and then double click it to open up a skeleton eventhandler into which you can insert your code. When you do it this way, VS automatically wires up the event for you.

Assuming you haven't done this, then add this line before any others in Form1_Load:

this.KeyDown += Form1_KeyDown;

to wire it up manually.

PS: Also don't forget to set the form's KeyPreview property to true.
Adam15y ago
ok now program works but doesnt work:D when I press some key , it does nothink
Vulpes15y ago
If you've put the 'symbol' files in the same folder as saveboard.bin, then this should work:

case (char)5:
return Image.FromFile(@"C:\Users\expire\Documents\Visual Studio 2010\Projects\Checkers\Checkers\bin\Debug\symbol1.bmp");
Adam15y ago
I cant run it because of this line:
case (char)5:
return Image.FromFile ("symbol1.bmp");

FileNotFoundException was unhandled I also try put there path to symbol1.bmp but it was the same
Vulpes15y ago
For now I'd store them in the same folder as saveboard.bin.

When you deploy the application, you could include them as a resource but I wouldn't worry about that just now.
Adam15y ago
Ok but I still dont know where should I save my images (symbol.bmp). Can u tell me please??
Vulpes15y ago
Taking those points in the same order:

string filePath = @"C:\Users\expire\Documents\Visual Studio 2010\Projects\Checkers\Checkers\bin\Debug\saveboard.bin"; // use full path here , and shou I load saveboard.bin if my DLL is called ClassLibrary1?

Well the class within the dll is called Saveboard so it seems as good a name as any. But you can call it anything you like - it's just a file :)

private void Form1_Load(object sender, EventArgs e) // why this method is here since Form existing
{

It's there so that you can see where the code should go.

string num = (i * 8 + j + 1).ToString();
PictureBox pb = (PictureBox)this.Controls["pictureBox" + num];
squares[i, j] = pb;

This is just a hack to get the pictureboxes into an array (using their names) so you don't have to have 64 assignment statements!

e.Handled = true;

You're intercepting all keystrokes in this routine before they go to any other controls you have on the form (though you may not have any!). If you set the e.Handled property to true this prevents the keystroke from being passed on to any other control.

default:
return;

If the user presses any other key, the method simply returns and the key is passed to any other controls that can accept input.

Well, the first thing I'd do is to put your pictureboxes into a 2D array so that the (i,j)th element of the pictureboxes array corresponds to the (i,j)th element of the Area array. Apart from that, it's just a matter of changing the code in the exe to reflect the fact that it's now a Windows Forms rather than a Console application - the code in the dll does not need changing.

I've quickly thrown together something below to (hopefully) get you going in the right direction. Notice that there's no need now for any static members. The code assumes that the pictureBoxes are called pictureBox1, pictureBox2 etc and have been added horizontally and then vertically in numerical order:

public partial class Form1 : Form
{
public Form1()
{
InitializeComponent();
}

private const int X = 8;
private const int Y = 8;
private Saveboard Board;
private bool choose = true;
private char[,] Area;
private PictureBox[,] squares;
private int prevCol, prevRow;
string filePath = @"c:\...\...\saveboard.bin"; // use full path here

private void Form1_Load(object sender, EventArgs e)
{
squares = new PictureBox[8, 8];
for (int i = 0; i < 8; i++)
{
for (int j = 0; j < 8; j++)
{
string num = (i * 8 + j + 1).ToString();
PictureBox pb = (PictureBox)this.Controls["pictureBox" + num];
squares[i, j] = pb;
}
}
// highlight first one
squares[0, 0].BorderStyle = BorderStyle.Fixed3D; // or whatever method you're using to highlight
LoadGame(); // not using Load as conflicts with an existing form member
}

private void Form1_KeyDown(object sender, KeyEventArgs e)
{
int col = 0 , row = 0;
bool redraw = false;

switch (e.KeyCode)
{
case Keys.Right:
Area = Board.MoveRight(out col, out row, out redraw);
break;

case Keys.Down:
Area = Board.MoveDown(out col, out row, out redraw);
break;

case Keys.Left:
Area = Board.MoveLeft(out col, out row, out redraw);
break;

case Keys.Up:
Area = Board.MoveUp(out col, out row, out redraw);
break;

case Keys.Enter:
Area = Board.EnterPressed(out col, out row, out redraw, out choose);
break;

case Keys.S:
Save();
redraw = false;
e.Handled = true;
return;

case Keys.Q:
e.Handled = true;
Close();
return;

default:
return;
}
e.Handled = true;
if (redraw) DrawBoard(false);
// as there's no cursor now, need this code
if (col != prevCol || row != prevRow)
{

squares[row, col].BorderStyle = BorderStyle.Fixed3D;
prevRow = row;
prevCol = col;
}
}

private void DrawBoard(bool firstTime)
{
//only need to do some things the first time the board is drawn
int num = 8;

for (int i = 0; i < X; i++)
{
for (int y = 0; y < Y; y++)
{
squares[i, y].Image = GetImage(i, y);
}

// not sure what you're doing about printing numbers

}

// not sure what you're doing about printing letters
if(choose)
label1.Text = "Player 1";
else
label1.Text = "Player 2";
}

private Image GetImage(int col, int row)
{
// may be a good idea to load all these images initially into an Image[] and then just return an element of this array

switch (Area[col, row])
{
case (char)5:
return Image.FromFile ("symbol1.bmp"); // or whatever
case (char)6:
return Image.FromFile ("symbol2.bmp");
case (char)4:
return Image.FromFile ("symbol3.bmp");
case (char)3:
return Image.FromFile ("symbol4.bmp");
default:
return null;
}
}

private void Save()
{
BinaryFormatter formatter = new BinaryFormatter();
using (FileStream fs = File.Create(filePath))
formatter.Serialize(fs, Board);
}

private void LoadGame()
{
if (File.Exists(filePath))
{
DialogResult result = MessageBox.Show("Do you want to load the previous game?", "Load Game", MessageBoxButtons.YesNo);
if (result == DialogResult.Yes)
{
BinaryFormatter formatter = new BinaryFormatter();
using (FileStream fs = File.OpenRead(filePath))
Board = (Saveboard)formatter.Deserialize(fs);
int col, row;
Area = Board.ReloadBoard(out col, out row, out choose);
if (col != prevCol || row != prevRow)
{
squares[prevRow, prevCol].BorderStyle = BorderStyle.FixedSingle;
squares[row, col].BorderStyle = BorderStyle.Fixed3D;
prevRow = row;
prevCol = col;
}
else
{
Board = new Saveboard();
Area = Board.InitializeBoard();
}
}
else
{
Board = new Saveboard();
Area = Board.InitializeBoard();
}
DrawBoard(true);
}
}

private void Form1_FormClosed(object sender, FormClosedEventArgs e)
{
DialogResult result = MessageBox.Show("Do you want to save the state of the game?", "Save Game", MessageBoxButtons.YesNo);
if (result == DialogResult.Yes) Save();
}
}

With regard to resizing everything together, I'd check out the Dock and Anchor properties.

I have design done, so I have 68 picture boxes in 2 colours. Now I dont know where to start. How can I do that I press downArrow, pictureBox below will highlighted. Then I dont know , how program will know that these 64 pictureboxes is my Area and Symbol is picture of figurine. And how & where can I use my DLL?And also I would like that if program is running and I click to lower right edge, and spread window, whole Board will also spread with window, so pictureboxes will increase.

Using a cursor is impractical for a windows forms application.

What I'd do is to find some way of highlighting the picture box which represents the currently selected square.

A simple way to do this would be to change the BorderStyle property from say 'None' to 'Fixed3D'.

Another (and perhaps better) way would be to have a different set of images for highlighted squares. When a square is selected, you can then switch in the highlighted image for the current symbol and the unhighlighted image for the previous square.

You'll need to set the Form's KeyPreview property to true and handle its KeyDown event so that you can trap all key presses made by the user. As before you'll need to switch on the key pressed and call the appropriate method in the dll.

You'll need a method to paint the board i.e. a grid of 64 pictureboxes, populate them with the appropriate images and highlight the current square.

You can try it but I think it'll be too slow to repaint the board after every move and you may therefore need to find some way to repaint only those squares which have changed. To do that you could iterate through the array returned by the dll and compare it with the Area array that was returned after the previous move.

So I fill windows form with picture boxes, and how can I make Cursor??I want control it with arrows. And when shoul I put arrows methods from DLL? would you mind to tell me some hints how to do it? thx

Yes, I'd use a grid of pictureboxes.

You can then load in images of your figurines and move them from box to box.

OK I wont add this exception, I want already have done Windows Form, and if I have more time a maybe add this exception. I dont have to have a full rating in school. What way I shoul do it in Windows Form? trow picture boxes or what do u think??
Vulpes15y ago
If you don't understand it already, then you should learn to do exception handling using try/catch/finally and the throw statement (see http://msdn.microsoft.com/en-us/library/s7fekhdy.aspx).

Frankly, the custom exception is artificial but it may be the only opportunity you'll have to put one into the program. Although nobody would do it like this in practice, they probably would place a 'normal' try/catch around any code involving disk access which can go wrong for a variety of reasons so at least it'll save you the bother of that :)
Adam15y ago
I dont understant why there is this Exception, what does it do?? Its really hard to understand your new code you are too high level :D I must carefully look at this tomorrow. Can u tell me what should I learn to understand you ?

As you haven't much time, I think you'll have to use the arrow keys rather than the mouse in the Windows Forms version because that will interface better with the dll.

To enable 'stepback' in the game, you'll need to 'remember' each move so you can retrace it if necessary. That's a matter of storing all the relevant variables so that the board can be restored to its former state. How you do it will depend on how many moves you want to store. If it's only one, you could save the board to a temporary disk file before each move or, if it's a small fixed number, you could have a corresponding number of disk files which are overwritten as necessary and then deleted completely when the game ends.

I've modified the Checkers class to accommodate a custom exception class which should be compiled with the .exe. Here's the code:

namespace Checkers
{
public class SaveLoadException : ApplicationException
{
public SaveLoadException(string message) : base(message)
{
}

public override string ToString()
{
return Message;
}
}

class Checkers
{
static Saveboard Board;
static char[,] Area;
static bool choose = true;

static void DrawBoard(bool firstTime)
{
//only need to do some things the first time the board is drawn

const int X = 8;
const int Y = 8;
int num = 8;

if (firstTime) Console.Clear();

// save cursor position
int origRow = Console.CursorTop;
int origCol = Console.CursorLeft;

// reset to 0,0
Console.SetCursorPosition(0, 0);

for (int i = 0; i < X; i++)
{
for (int y = 0; y < Y; y++)
{
Console.Write(Area[i, y]);
}
if (firstTime)
{
Console.WriteLine(num);
num--;
}
else
{
Console.WriteLine();
}
}

if (firstTime) Console.WriteLine("ABCDEFGH");
Console.SetCursorPosition(0, 10);
if(choose)
Console.WriteLine("Player 1");
else
Console.WriteLine("Player 2");
// restore cursor postion
Console.CursorTop = origRow;
Console.CursorLeft = origCol;
}

public static void Keys()
{
bool redraw = false;
int col = 0;
int row = 0;

while (true)
{
var ch = Console.ReadKey(true).Key; // to avoid echoing 'S' to console

switch (ch)
{

case ConsoleKey.RightArrow:

Area = Board.MoveRight(out col, out row, out redraw);
break;

case ConsoleKey.DownArrow:

Area = Board.MoveDown(out col, out row, out redraw);
break;

case ConsoleKey.LeftArrow:

Area = Board.MoveLeft(out col, out row, out redraw);
break;

case ConsoleKey.UpArrow:

Area = Board.MoveUp(out col, out row, out redraw);
break;

case ConsoleKey.Enter:

Area = Board.EnterPressed(out col, out row, out redraw, out choose);
break;

case ConsoleKey.S:

try
{
Save();
}
catch(SaveLoadException)
{
// swallow exception, silently, here
}
redraw = false;
break;

case ConsoleKey.Q:

CheckIfSave(0);
return;
}

if (redraw) DrawBoard(false);
Console.SetCursorPosition(col, row); // in case it's not in the right position following the move
}
}

static void Save()
{
BinaryFormatter formatter = new BinaryFormatter();
try
{
using (FileStream fs = File.Create("saveboard.bin"))
formatter.Serialize(fs, Board);
int x = 10, y = 0; // TEST CODE TO ENSURE THis WORKS
int z = x / y; // DITT0
}
catch(Exception ex)
{
throw new SaveLoadException("The following error occurred when attempting to save the board : " + ex.Message);
}
}

static void Load()
{
BinaryFormatter formatter = new BinaryFormatter();
try
{
using(FileStream fs = File.OpenRead("saveboard.bin"))
Board = (Saveboard) formatter.Deserialize(fs);
int x = 10, y = 0; // TEST CODE TO ENSURE THis WORKS
int z = x / y; // DITT0
}
catch(Exception ex)
{
throw new SaveLoadException("The following error occurred when attempting to load the board : " + ex.Message);
}
}

static void CheckIfSave(int flag) // now requires a parameter
{
Console.Clear();
Console.Write("Do you want to save the state of the game y/n : ");
string response = Console.ReadLine();
if (response.Length == 0) return;
try
{
if (Char.ToLower(response[0]) == 'y') Save();
}
catch(SaveLoadException slex)
{
Console.WriteLine("\n" + slex.Message);
if (flag == 1) Environment.Exit(1); // need to force process exit here because called from BreakHandler
}
}

static void BreakHandler(object sender, ConsoleCancelEventArgs args)
{
CheckIfSave(1);
}

static void Main()
{
Console.TreatControlCAsInput = false;
Console.CancelKeyPress += new ConsoleCancelEventHandler(BreakHandler); // handle pressing of Control-C

bool canLoad = false;

if (File.Exists("saveboard.bin"))
{
Console.Write("Do you want to reload the previous game y/n : ");
string response = Console.ReadLine();
char option = (response.Length == 0) ? 'n' : response[0];
if (option == 'q') return;
if (option == 'y')
{
canLoad = true;
try
{
Load();
}
catch(SaveLoadException slex)
{
canLoad = false;
Console.WriteLine("\n" + slex.Message + "\n\nPress any key to load a new board.\n");
Console.ReadKey();
}
if (canLoad)
{
int col, row;
Area = Board.ReloadBoard(out col, out row, out choose);
Console.SetCursorPosition(col, row);
}
}
}

if (!canLoad)
{
Board = new Saveboard();
Area = Board.InitializeBoard();
}

DrawBoard(true);
//Console.ReadKey(true); // not needed
Keys();
}
}
}

As you'll see there's some test code in the Save() and Load() methods which is just used to simulate an exception. It should be removed when you're sure it's working properly.

OOh thank you a lot! I must carefuly take a look to your new code, because now I know that I dont understant many of that. Also thank you for links that you ve posted me. What do you think will be the best way for Windows Form?? Control on arrows or with mouse?? I want do it the easiest way. Can u tell me pls about StepBeck, how would you do it?? thx
Vulpes15y ago
Although you'll know a lot of the C# language stuff already, I'd start by looking at the Windows Forms aspects of these videos ( http://msdn.microsoft.com/en-us/beginner/dd435692.aspx).

There's then a lot more material here (http://www.java2s.com/Tutorial/CSharp/0460__GUI-Windows-Forms/Catalog0460__GUI-Windows-Forms.htm) about using various types of controls.

I'll see if I can come up with a custom exception class that you can use when loading and saving the state of the game.
Vulpes15y ago
OK, I've now properly integrated the Load() and Save() methods into your Checkers class (new or changed code highlighted).

What happens now is that, if the file saveboard.bin exists on disk, the user is asked on starting the application whether (s)he wants to reload the previous game. Also, as well as the 'S' option to save the state of the game during play, I've also added a 'Q' option to quit when the user is then given the option to save the game prior to termination. I've removed the 'L' option as it's not the right place for it and you don't need it now anyway.

I've also incorporated an event (CancelKeyPress) into the Checkers class to deal with someone pressing Control-C when the application is running. This in fact is the only event which the Console class supports:

using System;
using System.Collections.Generic;
using System.Linq;
using System.Text;
using ClassLibrary1;
using System.Runtime.Serialization.Formatters.Binary;
using System.IO;

namespace Checkers
{
class Checkers
{
static Saveboard Board;
static char[,] Area;
static bool choose = true;

static void DrawBoard(bool firstTime)
{
//only need to do some things the first time the board is drawn

const int X = 8;
const int Y = 8;
int num = 8;

if (firstTime) Console.Clear();

// save cursor position
int origRow = Console.CursorTop;
int origCol = Console.CursorLeft;

// reset to 0,0
Console.SetCursorPosition(0, 0);

for (int i = 0; i < X; i++)
{
for (int y = 0; y < Y; y++)
{
Console.Write(Area[i, y]);
}
if (firstTime)
{
Console.WriteLine(num);
num--;
}
else
{
Console.WriteLine();
}
}

if (firstTime) Console.WriteLine("ABCDEFGH");
Console.SetCursorPosition(0, 10);
if(choose)
Console.WriteLine("Player 1");
else
Console.WriteLine("Player 2");
// restore cursor postion
Console.CursorTop = origRow;
Console.CursorLeft = origCol;
}

public static void Keys()
{
bool redraw = false;
int col = 0;
int row = 0;

while (true)
{
var ch = Console.ReadKey(true).Key; // to avoid echoing 'S' to console

switch (ch)
{

case ConsoleKey.RightArrow:

Area = Board.MoveRight(out col, out row, out redraw);
break;

case ConsoleKey.DownArrow:

Area = Board.MoveDown(out col, out row, out redraw);
break;

case ConsoleKey.LeftArrow:

Area = Board.MoveLeft(out col, out row, out redraw);
break;

case ConsoleKey.UpArrow:

Area = Board.MoveUp(out col, out row, out redraw);
break;

case ConsoleKey.Enter:

Area = Board.EnterPressed(out col, out row, out redraw, out choose);
break;

case ConsoleKey.S:

Save();
redraw = false;
break;

case ConsoleKey.Q:

CheckIfSave();
return;
}

if (redraw) DrawBoard(false);
Console.SetCursorPosition(col, row); // in case it's not in the right position following the move
}
}

static void Save()
{
BinaryFormatter formatter = new BinaryFormatter();
using (FileStream fs = File.Create("saveboard.bin"))
formatter.Serialize(fs, Board);
}

static void Load()
{
BinaryFormatter formatter = new BinaryFormatter();
using(FileStream fs = File.OpenRead("saveboard.bin"))
Board = (Saveboard) formatter.Deserialize(fs);
}

static void CheckIfSave()
{
Console.Clear();
Console.Write("Do you want to save the state of the game y/n : ");
string response = Console.ReadLine();
if (response.Length == 0) return;
if (Char.ToLower(response[0]) == 'y') Save();
return;
}

static void BreakHandler(object sender, ConsoleCancelEventArgs args)
{
CheckIfSave();
}

static void Main()
{
Console.TreatControlCAsInput = false;
Console.CancelKeyPress += new ConsoleCancelEventHandler(BreakHandler); // handle pressing of Control-C

if (File.Exists("saveboard.bin"))
{
Console.Write("Do you want to reload the previous game y/n : ");
string response = Console.ReadLine();
char option = (response.Length == 0) ? 'n' : response[0];
if (option == 'q') return;
if (option == 'y')
{
Load();
int col, row;
Area = Board.ReloadBoard(out col, out row, out choose);
Console.SetCursorPosition(col, row);
}
else
{
Board = new Saveboard();
Area = Board.InitializeBoard();
}
}
else
{
Board = new Saveboard();
Area = Board.InitializeBoard();
}
DrawBoard(true);
//Console.ReadKey(true); // not needed
Keys();
}
}
}

The only change needed to the dll is to add this method:

public char[,] ReloadBoard(out int col, out int row, out bool choose)
{
col = xpos;
row = ypos;
choose = player;
return Area;
}

I'll see if I can find you a decent online tutorial on Windows Forms though I'll warn you now - it's not something you can pick up in 5 minutes.
