how to make touchscreen-like mainform C#

I want to make my mainform draggable like smartphone touchscreen.
So i put up a bunifugradientpanel in it and dock it in mainform. also put a bunifudragcontrol and set targetcontrol property = 'bunifugradientpanel' and vertical property to 'false' also fixed property to 'false'. however, whenever i drag my panel to the right in rumtime, the portion of the mainform is showing which is the white part in the picture.
The white part of the screen is the mainform. what i want is to stop the dragging activity if bunifugradientpanel location on mainform is = (x=0,y=0) so the the portion of the mainform wont appear. thanks for your help guys.

BunifuGradientPanel is a Third Party control and that's why it can present drawing and flickering problems, my recommendation is that you use a common Panel System.Windows.Forms.Panel
That said, I created this code for you, makes a control draggable only from right to left and from left to right while the mouse button is pressed:
using System;
using System.Windows.Forms;
namespace JeremyHelp
{
public partial class Form1 : Form
{
public Form1()
{
InitializeComponent();
this.SetStyle(
ControlStyles.AllPaintingInWmPaint |
ControlStyles.UserPaint |
ControlStyles.DoubleBuffer,
true);
}
protected override void OnLoad(EventArgs e)
{
base.OnLoad(e);
this.SetDraggable(this.bunifuGradientPanel1, vertical: false);
}
protected override CreateParams CreateParams
{
get
{
CreateParams handleParam = base.CreateParams;
handleParam.ExStyle |= 0x02000000; // WS_EX_COMPOSITED
return handleParam;
}
}
private void SetDraggable(Control target, bool horizontal = true, bool vertical = true)
{
bool IsDraggable = false;
int
X = 0, Y = 0,
A = 0, B = 0;
target.MouseUp += (s, e) =>
{
IsDraggable = false;
X = 0; Y = 0;
A = 0; B = 0;
};
target.MouseDown += (s, e) =>
{
IsDraggable = true;
A = Control.MousePosition.X - target.Left;
B = Control.MousePosition.Y - target.Top;
};
target.MouseMove += (s, e) =>
{
X = Control.MousePosition.X;
Y = Control.MousePosition.Y;
if (IsDraggable)
{
if (horizontal) target.Left = X - A;
if (vertical) target.Top = Y - B;
}
};
}
}
}

C# - Hide created form on switch window (alt + tab) from code

I have a form that can create another form like this.
private void AEGISBot(String option) {
if (AEGIS == null) {
AEGIS = new Form();
AEGIS.ShowInTaskbar = false;
AEGIS.TopMost = true;
AEGIS.FormBorderStyle = System.Windows.Forms.FormBorderStyle.None;
AEGIS.Size = new Size(396, 191);
//AEGIS.Size = new Size(720, 720);
AEGIS.StartPosition = FormStartPosition.CenterScreen;
AEGIS.BackColor = Color.LightBlue;
AEGIS.TransparencyKey = AEGIS.BackColor;
Label AEGISLabel = new Label();
AEGISLabel.Location = new Point(0, 0);
AEGISLabel.Size = new Size(AEGIS.Size.Width, AEGIS.Size.Height);
AEGISLabel.TextAlign = ContentAlignment.MiddleCenter;
AEGISLabel.Text = "AEGIS";
AEGISLabel.Font = new Font("Agency FB", 120, FontStyle.Bold);
AEGISLabel.ForeColor = System.Drawing.Color.Navy;
AEGIS.Controls.Add(AEGISLabel);
}
if (option == "show"){
AEGIS.Show();
}
}
But how to hide it from alt tab. I tried to add code like this.
protected override CreateParams CreateParams
{
get
{
CreateParams cp = base.CreateParams;
cp.ExStyle |= 0x80;
return cp;
}
}
My main form was successfully hidden from alt tab. But how to use it to created form ??
Thank you
-Edit
I am using Windows Form Application. With some form setting
this.ShowInTaskbar = false;
this.FormBorderStyle = System.Windows.Forms.FormBorderStyle.None;
this.ShowIcon = false;
this.WindowState = FormWindowState.Minimized;

Try using AEGIS.ShowDialog() instead of AEGIS.Show().

ToolStripDropDown transparent background and smooth Region

I'm trying to create a custom popup window in my winforms project, which looks like so:
The problem with this is that the edges are smooth...
I'm achieving this like so:
public partial class BubblePopup : ToolStripDropDown
{
private const int BORDERWIDTH = 6;
private SolidBrush _backgroundBrush;
private int _borderRadius = 20;
public BubblePopup()
{
this.BackColor = Color.Transparent;
InitializeComponent();
//Method 1
Region = new Region(ControlUtilities.CreateBubblePath(new Rectangle(BORDERWIDTH - 1, BORDERWIDTH - 1, ClientSize.Width - (BORDERWIDTH * 2), ClientSize.Height - (BORDERWIDTH * 2)), _borderRadius));
/////////////
_backgroundBrush = new SolidBrush(Color.Blue);
}
//Method 1
protected override void OnSizeChanged(EventArgs e)
{
Region = new Region(ControlUtilities.CreateBubblePath(new Rectangle(BORDERWIDTH - 1, BORDERWIDTH - 1, ClientSize.Width - (BORDERWIDTH * 2), ClientSize.Height - (BORDERWIDTH * 2)), _borderRadius));
base.OnSizeChanged(e);
}
////////
protected override CreateParams CreateParams
{
get
{
CreateParams cp = base.CreateParams;
cp.ExStyle = cp.ExStyle | 0x20;
return cp;
}
}
protected override void OnPaint(PaintEventArgs e)
{
}
}
If I don't use the code enclosed by Method1 comments and I'm setting the background to transparent and setting the CreateParams flag to support transparency im getting the following result(I also tried overriding the OnPaintBackground event as well not to call the base.OnPaintBackground I got a black background then):
So I would either need a popup with my custom path with smooth region, or a transparent background would also work for me.
Also here's the code how I'm showing the popup:
private GeneralPopup _popupItem = new GeneralPopup();
private ToolStripControlHost _popupControlHost;
private BubblePopup _popup;
public Form1()
{
InitializeComponent();
_popupControlHost = new ToolStripControlHost(_popupItem);
_popupControlHost.Padding = new Padding(0);
_popupControlHost.Margin = new Padding(0);
_popupControlHost.AutoSize = false;
_popupControlHost.BackColor = Color.Transparent;
_popup = new BubblePopup();
_popup.Padding = new Padding(0);
_popup.Margin = new Padding(0);
_popup.AutoSize = true;
_popup.DropShadowEnabled = false;
_popup.Items.Add(_popupControlHost);
}
private void button1_Click(object sender, EventArgs e)
{
_popup.Show(button1,10,10);
}
Thanks in advance

keep button position on panel resize

I've been messing around with something that should be simple.
I've moved jobs and trying to get some of the basic tools I have used before, but of course I don't have the old source to look at.
We had extended panel to have some standard properties and functions (save, close, save and close).
But I can't get the buttons to be positioned correctly on a resize. I put this ExtPanel on a form but the buttons keep disappearing as I resize, or don't move as expected (frozen on bottom right).
The class
public partial class ExtPanel: UserControl
{
private System.Windows.Forms.Button btnSaveandClose;
private System.Windows.Forms.Button btnCancel;
private System.Windows.Forms.Button btnSave;
public ExtPanel ()
{
InitializeComponent ();
}
// misc things this class does...
}
public partial class ExtPanel
{
private void InitializeComponent ()
{
this.btnSaveandClose = new System.Windows.Forms.Button();
this.btnCancel = new System.Windows.Forms.Button();
this.btnSave = new System.Windows.Forms.Button();
this.panel1 = new System.Windows.Forms.Panel();
this.panel1.SuspendLayout();
this.SuspendLayout();
//
// btnSaveandClose
//
this.btnSaveandClose.Location = new System.Drawing.Point(899, 689);
this.btnSaveandClose.Name = "btnSaveandClose";
this.btnSaveandClose.Size = new System.Drawing.Size(100, 30);
this.btnSaveandClose.TabIndex = 0;
this.btnSaveandClose.Text = "Save and Close";
this.btnSaveandClose.UseVisualStyleBackColor = true;
this.btnSaveandClose.Click += new System.EventHandler(this.Click_SaveandClose);
this.btnSaveandClose.Anchor = ((System.Windows.Forms.AnchorStyles) ((System.Windows.Forms.AnchorStyles.Bottom | System.Windows.Forms.AnchorStyles.Right)));
//
// btnCancel
//
this.btnCancel.Location = new System.Drawing.Point(687, 689);
this.btnCancel.Name = "btnCancel";
this.btnCancel.Size = new System.Drawing.Size(100, 30);
this.btnCancel.TabIndex = 1;
this.btnCancel.Text = "Cancel";
this.btnCancel.UseVisualStyleBackColor = true;
this.btnCancel.Click += new System.EventHandler(this.Click_Close);
this.btnCancel.Anchor = ((System.Windows.Forms.AnchorStyles) ((System.Windows.Forms.AnchorStyles.Bottom | System.Windows.Forms.AnchorStyles.Right)));
//
// btnSave
//
this.btnSave.Location = new System.Drawing.Point(793, 689);
this.btnSave.Name = "btnSave";
this.btnSave.Size = new System.Drawing.Size(100, 30);
this.btnSave.TabIndex = 2;
this.btnSave.Text = "Save";
this.btnSave.UseVisualStyleBackColor = true;
this.btnSave.Click += new System.EventHandler(this.Click_Save);
this.btnSave.Anchor = ((System.Windows.Forms.AnchorStyles) ((System.Windows.Forms.AnchorStyles.Bottom | System.Windows.Forms.AnchorStyles.Right)));
//
// panel1
//
this.panel1.AutoScroll = true;
this.panel1.Controls.Add(this.btnSave);
this.panel1.Controls.Add(this.btnCancel);
this.panel1.Controls.Add(this.btnSaveandClose);
this.panel1.Location = new System.Drawing.Point(0, 0);
this.panel1.Name = "panel1";
this.panel1.Size = new System.Drawing.Size(1008, 730);
this.panel1.TabIndex = 0;
//
// ExtPanel
//
this.Controls.Add(this.panel1);
this.Name = "ExtPanel";
this.Size = this.panel1.Size;
this.Click += new System.EventHandler(this.click_this);
this.panel1.ResumeLayout(false);
this.ResumeLayout(false);
}
#endregion
private System.Windows.Forms.Panel panel1;
}

Have you tried anchoring the button?
...I missed the anchoring code.
If you have a button in the lower right-hand corner that you want to stay in the lower right-hand corner when resizing the form, set it's anchor properties to Bottom, Right.
Update:
I loaded your code. You have a panel inside of ExtPanel. If you dock (Fill) that panel then you should be working fine by resizing ExtPanel.

Adding custom components programmatically at runtime

I'm having a problem using custom components at runtime.
I have this custom FlowLayoutPanel component:
public partial class UserControl1 : System.Windows.Forms.FlowLayoutPanel
{
[Browsable(false)]
protected override CreateParams CreateParams
{
get
{
CreateParams cp = base.CreateParams;
cp.ExStyle |= 0x20;
return cp;
}
}
protected override void OnPaintBackground(PaintEventArgs e){}
public UserControl1(){}
}
it has nothing complicated. All it does is making the background transparent.
I added this component to my Toolbox using it's dll and it works perfectly fine when I drag and drop it to my Form. The problem is, I can't add it programmatically at runtime.
When I run the code below it should draw the picture on top of my custom FlowLayoutControl.
But unfortunately it does nothing.
The custom component is under the WindowsFormsControlLibrary1 namespace.
namespace MyFilm_v2._0
{
public partial class Form1 : Form
{
public Form1()
{
InitializeComponent();
UserControl1 test = new UserControl1();
test.BackColor = Color.Transparent;
test.Location = new Point(0, 110);
test.Width = 660;
test.Height = 478;
PictureBox b = new PictureBox();
b.Location = new Point(100, 100);
b.Width = 320;
b.Height = 475;
b.Image = Properties.Resources.movie;
this.Controls.Add(b);
//this.customScrollbar1.Minimum = 0;
//this.customScrollbar1.Maximum = test.DisplayRectangle.Height;
//this.customScrollbar1.LargeChange = customScrollbar1.Maximum / customScrollbar1.Height + test.Height;
//this.customScrollbar1.SmallChange = 15;//when click the arrows
//this.customScrollbar1.Value = Math.Abs(test.AutoScrollPosition.Y);
}
....

You adding picturebox to your test controls, but you not adding test to forms controls
public Form1()
{
InitializeComponent();
UserControl1 test = new UserControl1();
test.BackColor = Color.Transparent;
test.Location = new Point(0, 110);
test.Width = 660;
test.Height = 478;
PictureBox b = new PictureBox();
b.Location = new Point(100, 100);
b.Width = 320;
b.Height = 475;
b.Image = Properties.Resources.movie;
test.Controls.Add(b);
this.Controls.Add(test);//<- here
}
