原来很好看的界面是这样做出来的啊.

非常漂亮且逼真的灯控件，模拟灯坏，关闭，打开，危险4种状态，灯上可以输入文字进行标记，大小可以随意拖动！对于界面开发的程序员来说绝对是很好的帮助

给应用程序加一个启动画面-to the application plus a startup screen

重绘了静态控件按钮.同一静态控件上出现多个超连接,同样使用的API,测试使用MFC!-repaint static control button. Static Controls on the same multiple-Link, use the same APIs, testing the use of MFC!

cxGrid使用小结，内容比较详实，有很高的参考价值-Summary cxGrid use, relatively accurate, has high reference value

很好用的内存表控件 速度存取快 最新版本-database

基于C#的串口实现，适合学习，Windows窗体应用程序，也可以适当修改用于工程应用   

人们在使用SQL时往往会陷入一个误区，即太关注于所得的结果是否正确，而忽略了不同的实现方法之间可能存在的 性能差异，这种性能差异在大型的或是复杂的数据库环境中（如联机事务处理OLTP或决策支持系统DSS）中表现得尤为明 显。笔者在工作实践中发现，不良的SQL往往来自于不恰当的索引设计、不充份的连接条件和不可优化的where子句。在对 它们进行适当的优化后，其运行速度有了明显地提高！下面我将从这三个方面分别进行总结：-people in the use of SQL often fall into the trap, that is too focused on the findings is correct, and ignore a different method may exist between the performance differences, these differences in large or complex database environment (such as online transaction processing or decision support OLTP system DSS) has become even more obvious. In practice I found that the poor tend to SQL from inappropriate design of the index, not fully connected and non-optimal conditions where the phrase. On their proper optimization, and their operating speed has been improved! Now I will be three aspects of this summary :

一个界面程序，显示一个生动按钮。- A contact surface procedure, demonstrates a vivid button.

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?
