rotary progressbar

Are you looking for something similar to this?

 

It sounds like you're looking to create a custom rotary progress bar in C# for a desktop application without relying on any third-party libraries. To start from scratch, we can break down the process into a few key steps.

1. Designing the Rotary Progress Bar: Think about how you want your rotary progress bar to look and behave. Consider factors like the size, color, animation, and progress indication.

2. Creating the User Control in C#: You can start by creating a new user control in your C# project. This control will encapsulate the logic and appearance of your rotary progress bar.

3. Drawing the Rotary Progress Bar: Within your user control, you'll need to override the OnPaint method to handle the drawing of your rotary progress bar. You can use graphics functions to draw the circular shape and fill it based on the progress.

Here's a simple example to get you started:

using System;
using System.Drawing;
using System.Windows.Forms;

public class RotaryProgressBar : UserControl
{
    public int Progress { get; set; }

    protected override void OnPaint(PaintEventArgs e)
    {
        base.OnPaint(e);

        Graphics g = e.Graphics;
        Rectangle rect = new Rectangle(10, 10, Width - 20, Height - 20);

        g.DrawEllipse(Pens.Black, rect);
        g.FillPie(Brushes.Blue, rect, -90, 3.6f * Progress); // 3.6f represents each angle for 1% progress
    }
}

In this code snippet, we're creating a basic rotary progress bar that draws a filled portion of a circle based on the progress percentage.

Remember to customize and expand upon this code to fit your specific requirements. You can add features like animations, custom styling, and event handling to enhance the usability of your rotary progress bar.

Feel free to ask if you need further assistance or if you have any specific requirements in mind for your rotary progress bar. Good luck with your desktop app development!
