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

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.

Description: 平面、带图片的按钮该例子应用从CButton派生而来的CButtonST类和从CDC派生而来的CMemDC类，来实现平面、带图片的按钮，这两个类不需任何修改即可使用，方便、实用，该例子还应用从CStatic派生而来的CHyperLink类实现了在对话框实现超连接，使用跟上面两个类一样方便，值得学习。- The plane, the belt picture button this example application
derives the CButtonST kind from CButton which comes and the CMemDC
kind which derives from CDC comes, realizes the plane, the belt
picture button, these two kinds do not need any revision then to use,
convenient, practical, this example also applied the CHyperLink kind
which derived from CStatic comes to realize in the dialog box has
realized the ultra connection, used is equally convenient with above
two kinds, is worth studying.

Description: 我们需要控制滑动条，但默认情况下看起来太简单了？希望CBitmapSlider这个类,可以帮助您。 CBitmapSlider的主要特点,透明效果滑动条,自定义大小，自由闪烁,基本思路是使用CMemDC执行双重缓冲，并采用从显示透明位图功能，我们需要在工程中插入位图资源进入项目。 可以插入大的位图， 但也有一些限制，最好不要太大。-I hope this class, CBitmapSlider , can help you.All you have to do is read this article and make a few bitmaps.
