So, I am trying to emulate the minesweeper game in winforms, just as an exercise. So far I have two classes, one called "Cell" which derives from regular button class, but has few properties of its own and a class that handles the logic (basically I made a two-dimensional array filled with objects of type "Cell" and populate it with bombs). I ran into a problem - how do I attach my array of "Cell" button controls to the form? Without re-writing everything from scratch? Both classes are unfinished obviously, it's just that I wanted to check how it would look on a form and realized that I am stuck.
Here is my Cell class
class Cell : Button
{
//private GraphicsPath path;
const int width = 20;
const int height = 20;
public byte Value { get; set; }
public bool IsBomb { get; set; }
public Cell()
{
}
public Cell(int x, int y)
{
this.Location = new Point(x, y);
}
protected override void OnPaint(PaintEventArgs pevent)
{
base.OnPaint(pevent);
this.Width = width;
this.Height = height;
}
protected override void OnClick(EventArgs e)
{
base.OnClick(e);
this.Text = Value.ToString();
}
}
And here is my array class
class CellArray
{
private int _rows = 0;
private int _columns = 0;
private int _bombAmount = 0;
private Random rand;
private Cell[,] cellMatrix;
public CellArray(int rows, int columns, int bombAmount)
{
_rows = rows;
_columns = columns;
_bombAmount = bombAmount;
populate();
setBombs();
}
private void populate()
{
cellMatrix = new Cell[_rows, _columns];
for (int i = 1; i < _rows; i++)
{
for (int j = 1; j < _columns; j++)
{
cellMatrix[i, j] = new Cell();
cellMatrix[i, j].IsBomb = false;
}
}
}
private void setBombs()
{
//*****************************************QUESTIONABLE************************************
rand = new Random();
int k = 1;
while (k < _bombAmount)
{
Flag:
{
int i = rand.Next(_rows);
int j = rand.Next(_columns);
if (cellMatrix[i, j].IsBomb == false)
cellMatrix[i, j].IsBomb = true;
else
goto Flag;
}
}
//*****************************************QUESTIONABLE************************************
for (int i = 1; i < _rows; i++)
{
for (int j = 1; j < _columns; j++)
{
if (cellMatrix[i - 1, j - 1].IsBomb == true)
{
cellMatrix[i, j].Value++;
}
if (cellMatrix[i - 1, j].IsBomb == true)
{
cellMatrix[i, j].Value++;
}
if (cellMatrix[i, j - 1].IsBomb == true)
{
cellMatrix[i, j].Value++;
}
if (cellMatrix[i - 1, j + 1].IsBomb == true)
{
cellMatrix[i, j].Value++;
}
if (cellMatrix[i, j + 1].IsBomb == true)
{
cellMatrix[i, j].Value++;
}
if (cellMatrix[i + 1, j + 1].IsBomb == true)
{
cellMatrix[i, j].Value++;
}
if (cellMatrix[i + 1, j].IsBomb == true)
{
cellMatrix[i, j].Value++;
}
if (cellMatrix[i + 1, j - 1].IsBomb == true)
{
cellMatrix[i, j].Value++;
}
}
}
}
}
how do I attach my array of "Cell"
button controls to the form
This issue can be solved similar to this one:
Using programatically created CheckBoxes in Windows Form [C#]
The idea is to use YourForm.Controls.Add(...). Don't forget to provide proper locations for your cells/buttons within the forms coordinate system.
Of course, I would like to mention that IMHO deriving Cell from Button is a horrible design decision. Better separate your data classes (like Cell) completely from the GUI classes (like Button) and choose a technique like the one Asher suggested in his first answer (add a cell to the Tag property of each Button) to create a connection between Cell objects and corresponding Button objects.

Using Visual Studio C# ASP.NET I need to calculate how many letters 'u' does each path has.
Input :
zzzzzzzzzuzuzzz
uuzuuzuuzuuuzzz
zuzuzzuzuuzuzuz
zuzuzzuzzuzuuuz
zuuuuuuuzuzzzzz
zzzzzuuuzzzzzzz
Picture of the map and given data for better quality
Output :
2
21
14
I have this code right now.
It finds the paths (there's 2 total), but now I need to find how many letters 'u' does each path has.
public partial class WebForm1 : System.Web.UI.Page
{
protected void Page_Load(object sender, EventArgs e)
{
string path = "App_Data/Map.txt";
string[] lines = File.ReadAllLines(HttpContext.Current.Server.MapPath(path));
int Width = int.Parse(lines[0]);
int Height = int.Parse(lines[1]);
Label4.Text = "Width: " + Width.ToString();
Label5.Text = "Height: " + Height.ToString();
}
protected void Button1_Click(object sender, EventArgs e)
{
string path = "App_Data/Map.txt";
string map = File.ReadAllText(HttpContext.Current.Server.MapPath(path));
char[][] grid = GetGridGFromMap(map);
int NumberOfMoles = TaskUtils.LettersIsU(grid);
Label1.Text = "Letters U count: " + NumberOfMoles.ToString();
}
private char[][] GetGridGFromMap(string map)
{
string[] lines = map.Split('\n');
char[][] grid = new char[lines.Length][];
for(int i =0; i < lines.Length; i++)
{
grid[i] = lines[i].ToCharArray();
}
return grid;
}
}
class TaskUtils
{
public static int LettersIsU(char[][] grid)
{
int count = 0;
for (int i = 0; i < grid.Length; i++)
{
for (int j = 0; j < grid[i].Length; j++)
{
if (grid[i][j] == 'u')
{
count++;
SetCountedLetters(grid, i, j);
}
}
}
return count;
}
private static void SetCountedLetters(char[][] grid, int i, int j)
{
if (i < 0 || i >= grid.Length || j < 0 || j >= grid[i].Length || grid[i][j] == 'z')
return;
grid[i][j] = 'z';
SetCountedLetters(grid, i + 1, j);
SetCountedLetters(grid, i - 1, j);
SetCountedLetters(grid, i, j + 1);
SetCountedLetters(grid, i, j - 1);
}
}
}
the problem i'm facing right now is that i don't know how to check on the opponent's move which ships it sinks so i can display a message saying "Your ____ has sunk".
this is the code i have written

i tried adding a switch with choices 1-4 but it didn't work i've also tried having a int[] ship Hits = new int[] {0,0,0,0} and just adding 1 every time a ship was hit but that didn't go as planned because i didn't know how to bind each item of the array to a ship . and i think that's about it
One approach that you might find helpful would be to bundle up all the information about a Ship into a class. This is an abstraction that could make it easier for displaying ship names when they are sunk. At the same time, use inheritance so that a Ship is still a PictureBox with all the functionality that implies.
Ship minimal class example
Member properties tell us what we need know about a ship. Use enum values to make the intent perfectly clear.
class Ship : PictureBox
{
#region P R O P E R T I E S
[Description("Type")]
public τύπος τύπος
{
get => _τύπος;
set
{
if (!Equals(_τύπος, value))
{
_τύπος = value;
switch (_τύπος)
{
case τύπος.Αεροπλανοφόρο: Image = Image.FromFile(Path.Combine(_imageDir, "aircraft-carrier.png")); break;
case τύπος.Αντιτορπιλικό: Image = Image.FromFile(Path.Combine(_imageDir, "destroyer.png")); break;
case τύπος.Πολεμικό: Image = Image.FromFile(Path.Combine(_imageDir, "military.png")); break;
case τύπος.Υποβρύχιο: Image = Image.FromFile(Path.Combine(_imageDir, "submarine.png")); break;
}
}
}
}
τύπος _τύπος = 0;
public bool Sunk { get; set; }
[Description("Flag")]
public σημαία σημαία
{
get => _σημαία;
set
{
_σημαία = value;
onUpdateColor();
}
}
σημαία _σημαία = σημαία.Player;
#endregion P R O P E R T I E S
private void onUpdateColor()
{
var color =
Sunk ? Color.Red :
σημαία.Equals(σημαία.Player) ?
Color.Navy :
Color.DarkOliveGreen;
for (int x = 0; x < Image.Width; x++) for (int y = 0; y < Image.Height; y++)
{
Bitmap bitmap = (Bitmap)Image;
if (bitmap.GetPixel(x, y).R < 0x80)
{
bitmap.SetPixel(x, y, color);
}
}
Refresh();
}
public Point[] Hits { get; set; } = new Point[0];
public override string ToString() =>
$"{σημαία} {τύπος} # {((TableLayoutPanel)Parent)?.GetCellPosition(this)}";
private readonly static string _imageDir =
Path.Combine(AppDomain.CurrentDomain.BaseDirectory, "Images");
}
Where enum values are:
enum Direction
{
Horizontal,
Vertical,
}
enum τύπος
{
[Description("Aircraft Carrier")]
Αεροπλανοφόρο = 5,
[Description("Destroyer")]
Αντιτορπιλικό = 4,
[Description("Military")]
Πολεμικό = 3,
[Description("Submarine")]
Υποβρύχιο = 2,
}
/// <summary>
/// Flag
/// </summary>
enum σημαία
{
Player,
Opponent,
}
Displaying ships names when they are sunk
When the inherited Ship version of PictureBox is clicked the information is now available.
private void onAnyShipClick(object sender, EventArgs e)
{
if (sender is Ship ship)
{
MessageBox.Show(ship.ToString());
}
}

I am a total newbie to programming and i have been following some tutorials on array related to housie ticket generator.The point where I am stuck is that, I have to check each rows and each rows of the 3x9 matrix should not have more the two empty cells or it cannot have more then two cells filled next to each other.I am putting random numbers on the arrays and trying to validate the rules but,the program crashes. Can someone please give me an idea.?
This is what i've tried.
for(int columnIndex=0;columnIndex<=6;columnIndex++)
{
if(game[i,columnIndex+2]!=0)
{
return -1;
}
}
And this is the whole code
using System;

Why your for loop does not work:
for (int columnIndex = 0; columnIndex <= 6; columnIndex++)
{
if (game[i, columnIndex + 2] != 0)
{
return -1;
}
}
This loop does not take j into account. It is testing for previous numbers added, as soon as one previous number fails this test, it will fail indefinitely. This creates an infinite loop. This loop also fails if a number is placed in any position past 1, while it needs to fill 5 positions to succeed. This is mathematically impossible.
This:
'should not have more the two empty cells or it cannot have more then two cells' is also mathematically impossible. a row of 9 cannot have less than 2 full and less than 2 empty at the same time.
I think you are after 2 empty or full consecutively in a row. For that testing for two empty in a row cannot be achieved as it starts empty, and you are testing it before you fill it. Fortunately this is a redundant test that will always be true based on all of the other test cases.
No more than 2 full in a row is possible, but can also lead to impossible scenarios. I have added a check that resets the scenario if it has not found the solution after 1000 guesses.

So Im making tetris and I need to make 7 blocks. The problem is is that I have to copy paste the code in 7 different classes(and then changing the grid) so I thought maybe using subclass would be much easier. The problem is I dont know how to do that.
this is my general block class:
public class Block
{
Color Color;
const int x = 4;
const int y = 4;
bool[,] vorm;
Texture2D block;
float FallTimer;
public bool FallingBlock = false;
Random Random = new Random();
ZBlock zBlock = new ZBlock();
TBlock tBlock = new TBlock();
SBlock sBlock = new SBlock();
OBlock oBlock = new OBlock();
JBlock jBlock = new JBlock();
LBlock lBlock = new LBlock();
IBlock iBlock = new IBlock();
public void HandleInput()
{
if (Tetris.inputHelper.KeyPressed(Keys.Down))

So How can I use this class to create other 7 block classes(T, L, I, O etc) easily?
Edit: My block all looks like this:
{
const int x = 4;
const int y = 4;
public bool[,] tblock()
{
vorm = new bool[x, y];
for (int i = 0; i < x; i++)
for (int j = 0; j <y; j++)
{
vorm[i, j] = false;
vorm[0, 1] = true;
vorm[1, 1] = true;
vorm[1, 0] = true;
vorm[2, 1] = true;
}
Color = Color.Indigo;
return vorm;
}
public void RotationLinks(InputHelper inputhelper)
{
bool[,] nieuw = new bool[x, y];
if (inputhelper.KeyPressed(Keys.Left))
{
for (int a = 0; a < 4; ++a)
for (int b = 0; b < 4; ++b)
nieuw[a, b] = vorm[x - a - 1, b];
vorm = nieuw;
}
}
}
}
So to make other 6 I copied theh whole code and change the grid value. Is there a possible way to make it easier using bock class?
I have program that is some kind of testing. I keep questions in panel, but when I run my program, it show the middle of panel. How to make it show the beginning of the panel?
private void Form1_Load(object sender, EventArgs e)
{
for (int i = 0; i < 10; i++)
{
Dictionary<string, bool> answers = new Dictionary<string,bool>();
for (int j = 0; j < 4; j++)
{
string ans = "Відповідь " + (j+1);
bool flag = false;
if( i > 5)
{
if( j == 0 || j == 2)
{
flag = true;
}
}else
if (j == 0)
{
flag = true;
}
answers.Add(ans, flag);
}
string q_text = "Питання № " + (i+1);
this.AddQuestion(q_text, answers);
}
panel1.ScrollControlIntoView(panel1.Controls[0]);
}
Try to set focus on the first control in the panel on Form_Load event:
panel1.Controls[0].Select();
You could use:
The ScrollControlIntoView method:
panel.ScrollControlIntoView(panel.Controls[0]);
Panel's VerticalScroll property:
panel.VerticalScroll.Value = 0;
