only one of 4 picture boxes appear and picture appears in 100*55 rectangle

I am working on a project, but I face a problem. I cannot find the solution, maybe you can help me.
Below you can see the details of my code:
private void InitializeComponent()
{
this.BKezdes = new System.Windows.Forms.Button();
this.PPalya = new System.Windows.Forms.Panel();
this.LPalyaMerete = new System.Windows.Forms.Label();
this.CBPalyaMerete = new System.Windows.Forms.ComboBox();

this.PKezelo.SuspendLayout();
this.SuspendLayout();
//

this.BKezdes.Size = new System.Drawing.Size(208, 64);
this.BKezdes.TabIndex = 0;
this.BKezdes.Text = "Kezdés";

this.ResumeLayout(false);
}
public partial class Fkepernyo : Form

List<Mezo> mezok;
public Fkepernyo()
{
InitializeComponent();
}
private void BKezdes_Click(object sender, EventArgs e)
{
mezok = new List<Mezo>();
int xKezdes = 1;
int yKezdes;
int width = 20;
int height = 20;
//MessageBox.Show(PPalya.Width + " " + PPalya.Height);
for (int i = 0; i <2; i++)
{
yKezdes = 1;
for (int j = 0; j < 2; j++)
{
m = new Mezo(xKezdes, yKezdes, width, height, 1);
PPalya.Controls.Add(m);
mezok.Add(m);
//MessageBox.Show(""+m.Location);
//MessageBox.Show(i + " " + j);
yKezdes += width;
}
xKezdes += height;
}
/*foreach (var item in mezok)
{

}*/
}
void PBPalyaElemek_MouseClick(object sender, MouseEventArgs e)
{
if (e.Button == MouseButtons.Left)
MessageBox.Show("Left button clicked");
}
private void CBPalyaMerete_SelectedIndexChanged(object sender, EventArgs e)
{
}0
}
public Mezo(int x, int y, int width, int height,int kep)
{
PictureBox PBPalyaElemek;
PBPalyaElemek = new PictureBox();
PBPalyaElemek.Width = width;
PBPalyaElemek.Height = height;
var redX = new Bitmap(rings_and_x_s.Properties.Resources.red_x);
var greenCircle = new Bitmap(rings_and_x_s.Properties.Resources.green_circle);
if (kep == 1)
{
PBPalyaElemek.Image = greenCircle;
}
else
{
PBPalyaElemek.Image = redX;
}
PBPalyaElemek.Location = new Point(x, y);
PBPalyaElemek.SizeMode = PictureBoxSizeMode.Zoom;
PBPalyaElemek.MouseClick += PBPalyaElemek_MouseClick;
PBPalyaElemek.BorderStyle = BorderStyle.Fixed3D;
Controls.Add(PBPalyaElemek);
}
There are two problems:
When I try to display the images on the screen, it only appears in 100 * 55 rectangles.
When I give the instruction to generate 4 picture boxes, the first one appears and the others do not.
I would appreciate any idea which help me to find a solution.

Gmap.net can't show multi markers use C# winform

I want show multi marker on Map , but seem can't , code follow :
button1_Click show Position ,button2_Click show markers !
anyone give me any instructions? thanks.
private void button1_Click(object sender, EventArgs e)
{
gmap.DragButton = MouseButtons.Left;
gmap.MapProvider = GMapProviders.GoogleMap;
gmap.Position = new PointLatLng(25.037531, 121.5639969);
gmap.MinZoom = 5;
gmap.MaxZoom = 100;
gmap.ShowCenter = false;
gmap.Zoom = 15;
}
private void button2_Click(object sender, EventArgs e)
{
Random r = new Random();
var marker = new GMarkerGoogle(new PointLatLng(r.Next(25, 500), 121), GMarkerGoogleType.green);
var marker1 = new GMarkerGoogle(new PointLatLng(r.Next(25, 500), 121), GMarkerGoogleType.pink);
var marker2 = new GMarkerGoogle(new PointLatLng(r.Next(25, 500), 121), GMarkerGoogleType.blue);
var marker3 = new GMarkerGoogle(new PointLatLng(r.Next(25, 500), 121), GMarkerGoogleType.yellow);
marker.IsVisible = true; marker1.IsVisible = true; marker2.IsVisible = true; marker3.IsVisible = true;
gMapOverlay.Markers.Add(marker);
gMapOverlay.Markers.Add(marker1);
gMapOverlay.Markers.Add(marker2);
gMapOverlay.Markers.Add(marker3);
gmap.Overlays.Add(gMapOverlay);
}

Your code is ok, but the problem with the random function that you use only generates integers, and a small change as 1 integer means changing a complete degree in either latitude or longitude and this is a hudge displacement.
So you have to generate a random Doubles number instead of Integers.
I edit the code to work correctly.
using GMap.NET;
using GMap.NET.WindowsForms.Markers;
public class Form1
{
private GMap.NET.WindowsForms.GMapOverlay gMapOverlay;
private Random rand = new Random();
private void Form1_Load(object sender, EventArgs e)
{
GMapControl1.DragButton = MouseButtons.Left;
GMapControl1.MapProvider = GMap.NET.MapProviders.GMapProviders.GoogleMap;
GMapControl1.Position = new PointLatLng(25.037531, 121.5639969);
GMapControl1.MinZoom = 5;
GMapControl1.MaxZoom = 20;
GMapControl1.ShowCenter = false;
GMapControl1.Zoom = 11;
gMapOverlay = new WindowsForms.GMapOverlay("markers");
gMapOverlay.IsVisibile = true;
}
private void button2_Click(object sender, EventArgs e)
{
var marker = new GMarkerGoogle(new PointLatLng(GetRandomDouble(24.8, 25.1), GetRandomDouble(121.3, 121.6)), GMarkerGoogleType.green);
var marker1 = new GMarkerGoogle(new PointLatLng(GetRandomDouble(24.8, 25.1), GetRandomDouble(121.3, 121.6)), GMarkerGoogleType.pink);
var marker2 = new GMarkerGoogle(new PointLatLng(GetRandomDouble(24.8, 25.1), GetRandomDouble(121.3, 121.6)), GMarkerGoogleType.blue);
var marker3 = new GMarkerGoogle(new PointLatLng(GetRandomDouble(24.8, 25.1), GetRandomDouble(121.3, 121.6)), GMarkerGoogleType.yellow);
marker.IsVisible = true;
marker1.IsVisible = true;
marker2.IsVisible = true;
marker3.IsVisible = true;
// Clear old markers
gMapOverlay.Markers.Clear();
gMapOverlay.Markers.Add(marker);
gMapOverlay.Markers.Add(marker1);
gMapOverlay.Markers.Add(marker2);
gMapOverlay.Markers.Add(marker3);
// Clear old overlay
GMapControl1.Overlays.Clear();
GMapControl1.Overlays.Add(gMapOverlay);
// Zoom the map to show all drawn markers
GMapControl1.ZoomAndCenterMarkers(gMapOverlay.Id);

How do i access these arrays so that i can multiply inputted values in the diagonal?

If I inputted 5, it will generate a square matrix by 5 (5x5)
How do I multiply 1, 7, 13, 19, 25?
Is there any applicable algorithm for my code so I could multiply the diagonals or do i need to rewrite a new one?
public partial class Form1 : Form {
public int e = 0;
int Row = 0;
int Column = 0;
int YAxisPosition = 0;
int XAxisPosition = 0;
int Counter = 0;
int PositionalValue = 0;
TextBox[] MyTextBoxDimA = new TextBox[999999];
TextBox tbRow = new TextBox();
Button MyButton = new Button();
public Form1() {
InitializeComponent();
}
private void Form1_Load(object sender, EventArgs e) {
AutoScroll = true;
WindowState = System.Windows.Forms.FormWindowState.Maximized;
//GENERATING THE SIZE BUTTON
tbRow = new TextBox();
tbRow.Text = "5";
tbRow.Size = new Size(100, 10);
tbRow.Location = new Point(0, 0);
Controls.Add(tbRow);
//GENERATE MATRIX BUTTON
MyButton = new Button();
MyButton.Text = "GENERATE MATRIX";
MyButton.Size = new Size(200, 25);
MyButton.Click += new EventHandler(MyButton_Click);
MyButton.Location = new Point(0, 30);
Controls.Add(MyButton);
}
public void MyButton_Click(object sender, EventArgs ee) {
//CODE FOR GENERATING MATRIX A
e = 1;
PositionalValue = 1;
Counter = 1;
//POSITION
YAxisPosition = 60;
XAxisPosition = 0;
Row = Convert.ToInt32(tbRow.Text);
Column = Convert.ToInt32(tbRow.Text);
while (Row >= e) {
while (Column >= Counter) {
MyTextBoxDimA[PositionalValue] = new TextBox();
MyTextBoxDimA[PositionalValue].Location =
new Point(XAxisPosition, YAxisPosition); //coordinates (start)
MyTextBoxDimA[PositionalValue].Size = new Size(70, 10);
MyTextBoxDimA[PositionalValue].Text = Convert.ToString(PositionalValue);
Controls.Add(MyTextBoxDimA[PositionalValue]);
XAxisPosition = XAxisPosition + 100;
PositionalValue++;
Counter++;
}
YAxisPosition = YAxisPosition + 50;
Counter = 1;
e++;
XAxisPosition = 0;
}
}
}

If you are looking for an algorithm:
static void Main(string[] args)
{
int n = 5;
int ans = 1;
int current = 1;
for (int i = 1; i <= n; i++)
{
ans = ans * current;
current += n + 1;
}
Console.WriteLine(ans);
}

Just loop from zero to the size of the matrix. The index will be used to get each diagonal value (this code assumes that each textbox contains an integer and is not blank):
int matrixSize = 5;
int product = 1;
for (int i = 0; i < matrixSize; i++)
{
product *= int.Parse(MyTextBoxDimA[i,i].Text);
}

Adding pictureBox to panel with codes

I have a panel in Visual Studio/windows form app.But I coulnd't add pictureBox on it with code.It is working if I work without panel however I need it.MyCodes:
PictureBox[] pipe = new PictureBox[3];
private void Form1_Load(object sender, EventArgs e)
{
CreatePipes(1);}
private void CreatetopPipes(int Number)
{
for (int i = 0; i <= Number; i++)
{
PictureBox temp = new PictureBox();
this.Controls.Add(temp);
temp.Width = 50;
temp.Height = 350;
temp.BorderStyle = BorderStyle.FixedSingle;
temp.BackColor = Color.Red;
temp.Top = 30;
temp.Left = 300;
topPipe[i] = temp;
topPipe[i].Visible = true;
}
}

You can use panelName.Controls.Add(temp), and i advise you to change a top of PictureBox in for loop to view all PictureBox, like this :
private void CreatetopPipes(int Number)
{
for (int i = 0; i <= Number; i++)
{
PictureBox temp = new PictureBox();
panelName.Controls.Add(temp);
temp.Width = 50;
temp.Height = 350;
temp.BorderStyle = BorderStyle.FixedSingle;
temp.BackColor = Color.Red;
temp.Top = temp.Height * panelName.Controls.Count;
temp.Left = 300;
topPipe[i] = temp;
topPipe[i].Visible = true;
}
}

button event with validation and actions

I need help with the Check button. After a user adds all the 42 numbers in the textbox and enter a number from 0-9 in the "Enter number" area and clicks on the start button, next what he should do is run through the array of labels with the red label or lblCovece and he should collect the same values like the number enters before. And after he clicks on the Check button, the programme should first validate if the value that is selected with the red label is the same as the number entered. If is valid the label should turn green and than the result should appear in the label lblResultE(the result for example should be like this: if the number entered is 2, the result it is 2+2+2...)and if is not valid in the lblResultE we take out 10 points. That's what i did by now with some help.:) thank you.

What makes your programm complicated and difficult to understand, is that you mix game logic with display logic.
I suggest you to redesign your game. It could look something like this:
public enum State
{
Empty, // Displays "Z"
Neutral, // Blue
Good, // Green
Bad // Red
}
public class Square
{
public int Number { get; set; }
public State State { get; set; }
}
public class Game
{
public const int Width = 7, Height = 6;
public Game()
{
Board = new Square[Width, Height];
}
public event EventHandler GameChanged;
public Square[,] Board { get; private set; }
public int CurrentX { get; private set; }
public int CurrentY { get; private set; }
public void Reset()
{
for (int x = 0; x < Width; x++) {
for (int y = 0; y < Height; y++) {
Board[x, y].State = State.Empty; // Always displayed in blue as "Z"
}
}
OnGameChanged();
}
public void MoveLeft()
{
if (CurrentX > 0) {
CurrentX--;
OnGameChanged();
}
}
public void MoveRight()
{
if (CurrentX < Width - 1) {
CurrentX++;
OnGameChanged();
}
}
// and so on
private void OnGameChanged()
{
EventHandler eh = GameChanged;
if (eh != null) {
eh(this, EventArgs.Empty);
}
}
}
In the form I would define pole to be a matrix as well (like the board). I show only a few relevant parts of the form code, to give you an idea of what I mean:
public class Form1 : Form
{
private Game game;
private Label[,] pole;
public Form1()
{
game = new Game();
game.GameChanged += new EventHandler(Game_GameChanged);
pole = new Label[Game.Width, Game.Height];
// Intialize pole.
// ...
}
void Game_GameChanged(object sender, EventArgs e)
{
for (int x = 0; x < Game.Width; x++) {
for (int y = 0; y < Game.Height; y++) {
Square square = game.Board[x, y];
Label label = pole[x,y];
switch (square.State) {
case State.Empty:
label.BackColor = Color.Blue;
label.Text = "Z";
break;
case State.Neutral:
label.BackColor = Color.Blue;
label.Text = square.Number.ToString();
break;
case State.Good:
label.BackColor = Color.Green;
label.Text = square.Number.ToString();
break;
case State.Bad:
label.BackColor = Color.Red;
label.Text = square.Number.ToString();
break;
default:
break;
}
}
}
// Place lblCovece according to game.CurrentX and game.CurrentY
// ...
}
private void bReset_Click(object sender, EventArgs e)
{
game.Reset();
}
private void bLeft_Click(object sender, EventArgs e)
{
game.MoveLeft();
}
private void bRight_Click(object sender, EventArgs e)
{
game.MoveRight();

Note how the Game class tells the form when changes happen through the event GameChanged. The form then updates the game display. In the game class, you can now concentrate on the game logic and do not have to deal with buttons and labels. You can also work with logical coordinates in the range [0..6] and [0..5] of the game board. This is easier than working with pixels. You delegate all the pixel calculations to the form.
My example is not complete, but when you try to implement it, you will see that it will be much easier to think about how the logic of the game should work.

Add an int score;
private void bCheck_Click(object sender, EventArgs e)
{
bool found = false;
foreach (Label l in pole)
{
if (l.Location == lblCovece.Location && l.Text == txtGoal.Text)
{
l.BackColor = Color.Green;
score += int.Parse(l.Text);
lblResultE.Text = score.ToString();
found = true;
}
}
if (!found)
{
score -= 10;
lblResultE.Text = score.ToString();
}
}
