使用Opencv+Zbar组合识别图片中的二维码，特别是标准的二维码，这里标准指的是二维码成像清晰，图片中二维码的空间占比在40%~100%之间，这样标准的图片，Zbar识别起来很容易，不需要Opencv额外的处理。(The Opencv+Zbar combination is used to identify two dimensional codes in the picture, especially the standard two-dimensional code. Here the standard refers to the two-dimensional code imaging clearly, and the space of the two-dimensional code in the picture is between the 40%~100%. So the standard picture, Zbar is very easy to recognize, and does not need additional processing of the Opencv.)

说明：  登录系统的时候，打开功能快速调用。在过滤中输入，明细功能的首拼或汉字，列表会自动检索你输入的数据，按上下键选择你想要打开的功能(直接在过滤文本框按上下键即可)，然后按回车即可调出功能。(When you log on to the system, turn on the function to call quickly. Input in the filter, the first spelling of detailed functions or Chinese characters, the list will automatically retrieve the data you entered, press the upper and lower keys to select the function you want to open (just press the upper and lower keys in the filter text box), and then press Enter to call out the function.)

VC++圆角窗体的实现例子，生成圆角形状的窗口，大家知道，默认状态下和一般情况下，窗体的边角都是矩形的，或许你看烦了这种窗口，想生成一种非标准的窗口，把边角美化成圆角，带弧度的那种窗口，本例子或许可以让你从中学习到这种窗体实现的方法。 　　本程序的实现实现思路是设置对话框背景为 “TRANSPARENT”（透明），并在WM_CTLCOLORDLG消息处理器中创建一支“空笔”（NULL）来绘制对话框背景，然后用TransparenBlt将自己的位图放到对话框上。

基本遗传算法和模拟退火算法，可扩展，运行效率高，可以广泛应用(Basic genetic algorithm and simulated annealing algorithm are scalable, efficient and can be widely used.)
