C#/ Visual studio 2019 || windows form autoscroll flickering

I am trying to make a Windows Form that shows display data from data a table. Every thing is working fine until I start scrolling in the Form using the auto scroll property.
I don't know why that's happening. I hope someone can help me.
private void allShowsToolStripMenuItem_Click(object sender, EventArgs e)
{
try
{
// Load All the Shows from the database
DataTable dt = accesse.LoadAllShows();
// Create the allShows From
Form allShows = new Form();
// Create the Controls for the AllShows form.
PictureBox[] pic = new PictureBox[dt.Rows.Count];

winforms refresh multiple panels

I am building a poker game where I need to show multiple poker hands at the same time. I can either show 1, 3, 5, or 10.
I have 1 main hand that will display all the time and I activate different views based on the amount of hands the player wants to play.
I have 2 main panels (main_hand_panel, and extra_hands_panel)
I add all the Panels in a List and when it's time, I call ShowHand on it.
I add the first poker hand to main_hand_panel like this:
Point startPosition = new Point(0, 0);
ComponentResourceManager resources = new ComponentResourceManager(typeof(MainScreen));
var mainPokerHand = new PokerPanel(startPosition, main_hand_panel.Size, offset, cardSize);
mainPokerHand.Initialize(resources);
this.main_hand_panel.Controls.Add(mainPokerHand);
allHands.Add(mainPokerHand);
Then depending on which screen I'm showing I draw and add the additional hands like this (five hands example shown)
public void DrawFivePlay(ComponentResourceManager resources)
{
Point startPosition = new Point(0, 0);
var containerSize = extra_hands_panel.Size;
containerSize.Height = Convert.ToInt32(containerSize.Height / 2);
containerSize.Width = Convert.ToInt32(containerSize.Width / 2);
for (int i = 0; i < 2; i++)
{
startPosition.Y = containerSize.Height * i;
var pokerHand = new PokerPanel(startPosition, containerSize, scale(offset, .30), scale(cardSize, .8));
pokerHand.Initialize(resources);
this.extra_hands_panel.Controls.Add(pokerHand);
allHands.Add(pokerHand);
}
startPosition.X = containerSize.Width;
startPosition.Y = 0;
for (int i = 0; i < 2; i++)
{
startPosition.Y = containerSize.Height * i;
var pokerHand = new PokerPanel(startPosition, containerSize, scale(offset, .30), scale(cardSize, .8));
pokerHand.Initialize(resources);
this.extra_hands_panel.Controls.Add(pokerHand);
allHands.Add(pokerHand);
}
}
When I'm ready to show the hands, I call reveal_click which goes through all the hands in List and displays them.
private void reveal_Click(object sender, EventArgs e)
{
foreach (var hand in allHands)
{
hand.ShowHand();
}
Application.DoEvents();
}
The interesting part is that it doesn't display the main hand, it will display all the others, but the only time it displays the first hand is when the program just started and we are playing only 1 hand. If I show any of the other play option, the first hand will not display anymore.
Here is the PokerPanel code:
namespace TEX_DrawPoker

I also use a timer to display the cards so that they stagger.
Any help would be appreciated.
Thanks,

Found my problem,
I was not clearing the controls between hand changes, so I was trying to update a panel that was in the background. Controls.Clear() before moving to the next hand fixed that for me. Sorry for the long post for nothing. :(

Have you considered refreshing the entire form?
Form1.Refresh();
or only refresh the panel
PokerPanel.Refresh();

C# using a new class to utilise a forms controls?

I would like to create a new dynamic chart control.
This chart will have a lot of code behind it that works out data calculations and then populates properties of the chart.
My form class is getting rather large and I'm now thinking of putting all this new code im going to create in a new class (possibly call it "DynmChart").
Normally to use controls I would create a new class and then instantiate the form in the new class.
But my form class is part of a winforms project that uses program.c as its main class.
main contains application.run Form1.
So how would I create all the code etc that calculates and then populates controls that are in my form.
Here's all my code.
2 classes

textBox8.Text = qtyPg.ToString();
}
}
}
program class is my MAIN class:
namespace RepSalesNetAnalysis
{
static class Program
{
/// <summary>
/// The main entry point for the application.
/// </summary>
[STAThread]
static void Main()
{
Application.EnableVisualStyles();
Application.SetCompatibleTextRenderingDefault(false);
Application.Run(new Form1());
}
}
}
any help would be great!
Many Thanks in Advance!

If I'm understanding your question right...
DynmChart should probably be created as a UserControl and used on forms where it's needed.
However, if you stay with your current approach:
You can use Encapsulation to separate responsibilities between the Form1 class (or your UserControl if you go that route) and a new Calculation class. The UI class would be responsible for display tasks, while the Calculation class would be responsible for number crunching. Simply create an instance of Calculation in Form1/your UserControl and use the Calculation instance to return results of the various calculations you need.
If the UI portion of your control is becoming unmanageable in terms of the amount of code in one file, the first thing to consider is using #region directives to hide parts of the code you are not working on (organize the code into blocks that logically belong together).
Another approach, if you need a lot of UI code and it's bloating your class file, is to use Partial Classes.

Custom MessageBox

I want to create a custom messagebox
but i want use the custom icons and custom sound in during show messagebox
how do I create this Messagebox??
I no want to use the shell32.dll and user32.dll
a messagebox the same as windows 7 for windows xp

I used a simple dialog with a static method ShowCustomButtonsDialog. I placed a text label in the top left corner and changed border style to Dialog. Method simply returns button index or -1.
public partial class CustomButtonsDialog : Form
{
private const int ButtonHeight = 24;
private const int ButtonPadding = 6;
private const int ButtonInnerPadding = 5;
private const int MaxFormWidth = 700;
private int buttonIndex = -1;
public int ButtonIndex
{
get { return buttonIndex; }
private set { buttonIndex = value; }
}
public static int ShowCustomButtonsDialog(string text, string title, params string[] buttonsText)
{
var dlg = new CustomButtonsDialog(text, title, buttonsText.ToList());
dlg.ShowDialog();
return dlg.ButtonIndex;
}
public static int ShowCustomButtonsDialog(string text, string title, List<string> buttonsText)
{
var dlg = new CustomButtonsDialog(text, title, buttonsText);
dlg.ShowDialog();
return dlg.ButtonIndex;
}
public CustomButtonsDialog()
{
InitializeComponent();
}
private CustomButtonsDialog(string text, string title, List<string> buttonsText)
{
InitializeComponent();
Text = title;
labelText.Text = text;
// добавить кнопки
var formWidth = ClientSize.Width;
List<int> buttonWidths;
using (var gr = CreateGraphics())
{
buttonWidths = buttonsText.Select(b => (int)gr.MeasureString(b, Font).Width + 2 * ButtonInnerPadding).ToList();
}
var totalButtonWd = buttonWidths.Sum() + (buttonWidths.Count - 1) * ButtonPadding;
if (totalButtonWd > formWidth)
{
if (totalButtonWd <= MaxFormWidth)
Width = Width - ClientSize.Width + totalButtonWd + ButtonPadding * 2;
else
{// trim some buttons
Width = Width - ClientSize.Width + MaxFormWidth;
totalButtonWd = ClientSize.Width - ButtonPadding * 2;
var avgWidth = (totalButtonWd - (buttonsText.Count - 1) * ButtonPadding) / buttonsText.Count;
var sumThins = buttonWidths.Sum(w => w <= avgWidth ? w : 0);
var countThins = buttonWidths.Count(w => w <= avgWidth);
var countFat = buttonsText.Count - countThins;
var spareRoom = totalButtonWd - sumThins;
var fatWidth = (countThins == 0) || (countFat == 0)
? avgWidth
: (spareRoom - (countThins - 1)*ButtonPadding)/countFat;
for (var i = 0; i < buttonWidths.Count; i++)
if (buttonWidths[i] > avgWidth) buttonWidths[i] = fatWidth;
}
}
// buttons' Y-coords and height
labelText.MaximumSize = new Size(totalButtonWd,
labelText.MaximumSize.Height);
var buttonTop = labelText.Bottom + ButtonPadding;
var formHeight = buttonTop + ButtonHeight + ButtonPadding;
Height = Height - ClientSize.Height + formHeight;
// do make buttons
var buttonLeft = ButtonPadding;
var tag = 0;
for (var i = 0; i < buttonWidths.Count; i++)
{
var button = new Button
{
Parent = this,
Width = buttonWidths[i],
Height = ButtonHeight,
Left = buttonLeft,
Top = buttonTop,
Text = buttonsText[i],
Tag = tag++
};
button.Click += ButtonClick;
buttonLeft = button.Right + ButtonPadding;
Controls.Add(button);
}
}
private void ButtonClick(object sender, EventArgs e)
{
ButtonIndex = (int) ((Button) sender).Tag;
Close();
}
}

Easiest way would be to create your own MessageBox window from scratch. If you are looking for hooks to default windows MessageBox you need to consider that later you can run into problems like compatibility with other Windows operating systems.
Here are couple of samples how to create your own MessageBox:

That will give you an idea about logic and how to start writing your own custom MessageBox.

why doesnt my panel show all my buttons in my c# application?

my panel in my windows form application doesn't include all the buttons i asked it to. It shows only 1 button, Here is the code
private void AddAlphaButtons()
{
char alphaStart = Char.Parse("A");
char alphaEnd = Char.Parse("Z");
for (char i = alphaStart; i <= alphaEnd; i++)
{
string anchorLetter = i.ToString();
Button Buttonx = new Button();
Buttonx.Name = "button " + anchorLetter;
Buttonx.Text = anchorLetter;
Buttonx.BackColor = Color.DarkSlateBlue;
Buttonx.ForeColor = Color.GreenYellow;
Buttonx.Width = 30;
Buttonx.Height = 30;
this.panelButtons.Controls.Add(Buttonx);
//Buttonx.Click += new System.EventHandler(this.MyButton_Click);
}
}

Aren't they all going to be on the same position?
Try setting Buttonx.Location = new Point(100, 200);
(but with different points for different buttons)

You could use a FlowLayoutPanel, which would take care of the layout for you, or you need to track the locations yourself, or which could look something like this:
private void AddAlphaButtons()
{
char alphaStart = Char.Parse("A");
char alphaEnd = Char.Parse("Z");
int x = 0; // used for location info
int y = 0; // used for location info
for (char i = alphaStart; i <= alphaEnd; i++)
{
string anchorLetter = i.ToString();
Button Buttonx = new Button();
Buttonx.Name = "button " + anchorLetter;
Buttonx.Text = anchorLetter;
Buttonx.BackColor = Color.DarkSlateBlue;
Buttonx.ForeColor = Color.GreenYellow;
Buttonx.Width = 30;
Buttonx.Height = 30;
// set button location
Buttonx.Location = new Point(x, y);
x+=30;
if(x > panel1.Width - 30)
{
x = 30;
y+=30;
}
this.panelButtons.Controls.Add(Buttonx);
//Buttonx.Click += new System.EventHandler(this.MyButton_Click);
}
}
