how to stop flickering C# winforms

Question

I have a program that is essentially like a paint application. However, my program has some flickering issues. I have the following line in my code (which should get rid of

Answer 1

Finally solved the flickering. Since I was drawing on a panel instead of the form the line of code below will not solve the flickering:

this.SetStyle(
    ControlStyles.AllPaintingInWmPaint | 
    ControlStyles.UserPaint | 
    ControlStyles.DoubleBuffer, 
    true);

SetStyle must be of type 'YourProject.YourProject' (or derived from it) hence, you have to create a class as such (so that you can use MyPanel which will be derived from SPaint.SPaint and hence allowing you to use doublebuffering directly for the panel - rather than the form):

using System;
using System.Collections.Generic;
using System.Linq;
using System.Text;
using SPaint; 

namespace YourProject
{
    public class MyPanel : System.Windows.Forms.Panel
    {
        public MyPanel()
        {
            this.SetStyle(
                System.Windows.Forms.ControlStyles.UserPaint | 
                System.Windows.Forms.ControlStyles.AllPaintingInWmPaint | 
                System.Windows.Forms.ControlStyles.OptimizedDoubleBuffer, 
                true);
        }
    }
}

After you've done this(although you should really never edit the designer code unless you truly know what you're doing) you'll have to edit the Form.Designer.cs. Inside this file you will find code that looks like this:

this.panelArea = new YourProject.MyPanel();

The above line needs to be changed to:

this.panelArea = new MyPanel(); 

After I completed these steps, my paint program no longer flickers.

For anyone else having the same issue, the problem is finally solved.

Enjoy!
