双缓冲问题

Question

我做了个游戏，老是闪烁，大家都说用双缓冲。
谁有关于双缓冲的例子，最好有注释。
谢谢！

Answer 1

你是不是用listview这个控件,如果晕这个的话.用doublebufferlistview就可以
你百度一下doublebufferlistview
兴许就找到问题的答案喽,good luck

Answer 2

  class DoubleBufferListView : ListView
    {
        public DoubleBufferListView()
        {
            SetStyle(ControlStyles.DoubleBuffer | ControlStyles.OptimizedDoubleBuffer | ControlStyles.AllPaintingInWmPaint, true);
            UpdateStyles();
        }
    }//
DoubleBufferListView lv=new DoubleBufferListView();
lv...

才十五分而已,还好拿意思,我每次求贴都是一百分...呵呵

15分。HOHO，手上有个之前用过的：using System;
using System.Collections.Generic;
using System.ComponentModel;
using System.Data;
using System.Drawing;
using System.Drawing.Drawing2D;
using System.Text;

    public partial class MainForm : Form
    {
        public SW swMain;        private BufferedGraphics backBuffer;            //双缓冲的缓冲区。        private BufferedGraphics backgroundBuffer;      //背景缓冲区：坐标轴，刻度，参考线
        public MainForm(SW sw)
        {
            InitializeComponent();            this.SetStyle(ControlStyles.OptimizedDoubleBuffer |
                   ControlStyles.ResizeRedraw |
                   ControlStyles.AllPaintingInWmPaint, true);            if (sw == null)
            {

            }
            else
            {

        }

            }
            //用背景缓冲区渲染双缓冲
            backgroundBuffer.Render(backBuffer.Graphics);            Graphics g = backBuffer.Graphics;            drawSW(g);                  //绘制方波
            drawFrame(g);               //绘制拖放时的边框
            backBuffer.Render(e.Graphics);      //双缓冲防闪烁（暂时未达到效果）        }
    
    }
}

Answer 4

  class DoubleBufferListView : ListView
    {
        public DoubleBufferListView()
        {
            SetStyle(ControlStyles.DoubleBuffer | ControlStyles.OptimizedDoubleBuffer | ControlStyles.AllPaintingInWmPaint, true);
            UpdateStyles();
        }
    }
把这个ListView改成其它的不可用吗?
