Windows Form Customized Message Box

Create two classes inside one class File

1. Create new class file give name as AnimtedMsgBox and inherit this class with Form Class as shown below:
   

   class AnimtedMsgBox :Form
   {
   }

   Or
   
   Add WindowsForm and give name as RNTP_MsgBox.cs
   
   And change class name if you want as given above then.
   
   
2. Add two references to this class:
   

   using System.Text.RegularExpressions;
   using System.Runtime.InteropServices;

3. Declare variables inside class as below:
   

   private const int CS_DROPSHADOW = 0x00020000;
   private static AnimtedMsgBox _msgBox;
   private Panel _plHeader = new Panel();
   private Panel _plFooter = new Panel();
   private Panel _plIcon = new Panel();
   private PictureBox _picIcon = new PictureBox();
   private FlowLayoutPanel _flpButtons = new FlowLayoutPanel();
   private Label _lblTitle;
   private Label _lblMessage;
   private List<Button> _buttonCollection = new List<Button>();
   private static DialogResult _buttonResult = new DialogResult();
   private static Timer _timer;
   private static Point lastMousePos;
   
   [DllImport("user32.dll", CharSet = CharSet.Auto)]
   private static extern bool MessageBeep(uint type);

4. And add below function to this class:
   

   private AnimtedMsgBox() {
       this.FormBorderStyle = System.Windows.Forms.FormBorderStyle.None;
       this.BackColor = Color.FromArgb(45, 45, 48);

       this.Width = 200;
   
       _lblTitle = new Label();
       _lblTitle.ForeColor = Color.White;
       _lblTitle.Font = new System.Drawing.Font("Segoe UI", 18);
       _lblTitle.Dock = DockStyle.Top;
       _lblTitle.Height = 50;
   
       _lblMessage = new Label();
       _lblMessage.ForeColor = Color.White;
       _lblMessage.Font = new System.Drawing.Font("Segoe UI", 10);
       _lblMessage.Dock = DockStyle.Fill;
   
       _flpButtons.FlowDirection = FlowDirection.RightToLeft;
       _flpButtons.Dock = DockStyle.Fill;
   
       _plHeader.Dock = DockStyle.Fill;
       _plHeader.Padding = new Padding(20);
       _plHeader.Controls.Add(_lblMessage);
       _plHeader.Controls.Add(_lblTitle);

       _plFooter.Padding = new Padding(20);
       _plFooter.BackColor = Color.FromArgb(37, 37, 38);
       _plFooter.Height = 75;
       _plFooter.Controls.Add(_flpButtons);
   
       _picIcon.Width = 32;
       _picIcon.Height = 32;
       _picIcon.Location = new Point(30, 50);
   
       _plIcon.Dock = DockStyle.Left;
       _plIcon.Padding = new Padding(20);
       _plIcon.Width = 70;
       _plIcon.Controls.Add(_picIcon);
   
       List < Control > controlCollection = new List < Control > ();
       controlCollection.Add(this);
       controlCollection.Add(_lblTitle);

       }

   }

5. Add one more class to this Class file or make separate class as give below:
   
   class ApplyAnimation
   {
   public Size FormSize;
   public AnimtedMsgBox.AnimateStyle Style;
   
   public ApplyAnimation(Size formSize, AnimtedMsgBox.AnimateStyle style)
   {
   this.FormSize = formSize;
   this.Style = style;
   }
   }

That’s it your Customized messagebox is ready, now lets see how to use it.

-To Use this Customized MessageBox

1. Open new or existing windows form and give reference to this class, In my example reference is
   using RNTP_MsgBox;
   
   
2. Add button and write messagebox code to button click event or any event as given below:
   
   AnimtedMsgBox.Show("Customized messagebox FadeIn", "title", AnimtedMsgBox.Buttons.OK, AnimtedMsgBox.Icon.Application, AnimtedMsgBox.AnimateStyle.FadeIn);
   
   Note:
   
   There are three animation for this customized messagebox:
   
   AnimtedMsgBox.AnimateStyle.FadeIn
   AnimtedMsgBox.AnimateStyle.SlideDown
   AnimtedMsgBox.AnimateStyle.ZoomIn
   
   There are new extra icon also avilable for this customized messagebox
   AnimtedMsgBox.Icon.Application
   AnimtedMsgBox.Icon.Shield
   AnimtedMsgBox.Icon.Search
