Description: 使用CMemDC类解决应用程序的闪烁问题
在你的MFC程序中解决闪烁问题是个烦心的工作。你可以在书上或者网上找到关于这方面的介绍，但是介绍的技术一般都是很复杂的或者是很难应用到已经存在的程序中去。
一个京城使用的技术叫做双缓冲。双缓冲使用一个新的缓冲来画屏幕，然后把整个的屏幕显示在真正的屏幕上。
这篇文章使用了叫做CMemDC的类，这个类封装了绝大部分写入off-screen缓冲区的方法。在已经存在的MFC或者是ActiveX控件中加入CMemDC类是非常方便的。
怎样在你的MFC程序中使用CMemDC
1.在你的工程中加入memdc.h文件。
2.在stdafx.h中加入代码#include \"memdc.h\"
3.为窗口做WM_ERASEBKGND的消息映射
4.象下面那样改变处理消息的代码：-use CMemDC category of applications to solve the problem flashing in your MFC process is resolved Flicker 000 bother work. You can book online or find this regard, But introducing the technology in general are very complex or difficult to apply to already existing programs. Beijing used a technique called double buffering. Double buffer using a new buffer to paint a screen, then the screen shows that the whole of the real on the screen. This article called CMemDC use of the category, this category included the majority of package off-screen buffer method. The existence of MFC or ActiveX add CMemDC category is very convenient. What in your MFC procedures used CMemDC one. In your works into memdc.h document. 2. In addition stdafx.h code # include "memdc.h" 3. For window W M_ERASEBK Platform: |

Description: Introduction
Do you need a slider but default control looks too simple? I hope this class, CBitmapSlider, can help you. All you have to do is read this article and make a few bitmaps.
Features
Transparency effect for both channel and thumb.
Customize size of the thumb.
Flicker free.
It uses CMemDC from Keith Rule s article to implement double buffering, and uses functions from Raja Segar s article to display transparent bitmap. -IntroductionDo you need a slider but default control looks too simple?

Description: // 经过改进后，画面刷新速度大大加快，绝对看不到任何的“扫描线”，帧数也从5帧一下就提高到了9帧，
// 几乎是两倍于前的速度。这究竟是什么原因呢？让我来讲述其中的道理。
// 因为圆是要一个一个画上去，所以每画一个圆，系统就要做一次图形的绘制操作，
// 图形的重绘是很占用资源的，当需要重绘的图形数量很多的时候，所造成的系统开销就特别大，
// 造成我们看到的那种刷新缓慢的情况。那么如何来解决这个问题呢？
//答案就是双缓冲，何谓“双缓冲”？它的基本原理就是：先在内存中开辟一块虚拟画布，
// 然后将所有需要画的图形先画在这块“虚拟画布”上，最后在一次性将整块画布画到真正的窗体上。
// 因为所有的单个图形的绘制都不是真正的调用显示系统来“画”，所以不会占用显示系统的开销，极大的提高的绘图效率。
-Is the double buffering, what is a "double buffering"? Its basic principle is: to create a virtual canvas in memory, and then will all need to draw the graphics first painting in the "virtual canvas", finally, in a one-off the entire piece of canvas painting real form.
