本系统是一个基于vs2010平台上的用c#开发的学生管理系统，可以对学生信息进行管理。数据库使用sql，基于.net的程序开发，不够完善，是.net期末考试的课程设计

该程序主要用于图像处理中直方图均衡化，语言环境VC++(The program is mainly used for image processing, histogram equalization, the language environment VC++)

对Excel.dll 再次封装，利用IDpose接口，释放Excel进程；自动读取Excel单元格的内容到System.data.dataTable，比传统读取的效率有提高；利用DataTable中的计算结果，再写回到Excel中，生成.xls 报告文件-Re-packaging of the Excel.dll using IDpose interface, the release of Excel process automatically read the contents of Excel cells into System.data.dataTable, the efficiency than the traditional reading has been improved the use of DataTable in the calculations, write back Excel, generate. xls report file

仿射密码体制加解密，较移位代换等加解密体制，更加优越。(Affine cipher encryption and decryption, a shift substitution and encryption and decryption system, more superior.)

说明：  AES算法（即 Rijndael 算法）是一个对称分组密码算法。数据分组长度必须是 128 bits，使用的密钥长度为 128，192 或 256 bits。对于三种不同密钥长度的 AES 算法，分别称为“AES-128”、“AES-192”、“AES-256”。本文在分析了 AES 加密原理的基础上着重说明了算法实现的具体步骤，并用 C++ 实现了对文件的加密和解密。(AES algorithm (Rijndael algorithm) is a symmetric block cipher algorithm.The data packet length must be 128 bits and the key length used is 128,192 or 256 bits.For the three AES algorithms with different key lengths, they are called "aes-128", "aes-192", and "aes-256".In this paper, on the basis of analyzing the principle of AES encryption, the concrete steps of the algorithm are emphatically explained, and the encryption and decryption of files are realized by C++.)
