用ADO打开关闭数据库的简单程序 初步了解关于ADO在MFC中的使用(用ADO打开关闭数据库的简单程序 初步了解关于ADO在MFC中的使用 Simple procedures for opening and closing the database with ADO preliminary understanding about use of ADO in MFC )

说明：  是一个图片见面预览，模拟工业触摸屏的画面，所以画面元素比较单一，但是仅仅做预览效果不错(Is an image preview meeting, simulation of industrial touch-screen picture, so the image elements of relatively simple, but only to do a good preview)

参数活动轮廓模型分割算法，运行稳定，且效果理想(Parametric active contour model segmentation algorithm, running stability, and the results are satisfactory)

MFC非常好用的绘图控件，实时更新采集数据图像非常方便，吐血推荐！(very useful resource for MFC painting)

信息系统建设过程中很有可能涉及与旧有系统和其它异构系统之间的集成，而在这些集成当中数据的共享和集成无疑是非常重要的部分。数据映射系统为快速响应异构数据结构和系统之间进行数据共享和集成的需求提供了有力的支持。(Information systems building process is likely to have involved with the old system and other integration between heterogeneous systems, and in which these integrated data sharing and integration is a very important part. Data mapping system for rapid response to heterogeneous data structures and systems for data sharing and integration needs to provide a strong support.)

SD程序基于STM32，底层的驱动程序已被写入，并有notes.it值得初级开发者学习。(SD program based on STM32, the underlying driver has been written, and there is a notes.it worthy of the primary developers to learn.)

C语言实现217卷积码的viterbi译码（软、硬判决的代码都有，运行时先在VC中分别运行软、硬判决的C程序，产生误比特率的数据并存储在.txt文件中，之后在matlab中读取数据，画出误比特率曲线，matlab程序也已给出）(C language achieve 217 viterbi decoding (including hard and soft decision,and the codes should be run in VC to generate and store the BER datas,and the to obtain BER curve in matlab))

介绍了如何将m文件转换成VC可调用的dll文件,在这章中介绍如何利用编译器将m文件转换成对应的CC++文件,并在VC中调用(on how to convert documents into m VC dll with the available documents, In this chapter, how to use the compiler to convert documents into m corresponding to the C C paper and called in VC)
