average of numbers that implements with C# in visual basic. i wrote it

地址簿管理系统，visual c++与Access数据库实现(Address book management system, Visual C + + and Access database to achieve)

g723语音压缩格式。里面包含了最新的说明文档和代码，可以使用VC来编译。对视频会议或者作VOIP的朋友很有帮助。(voice compression format. The latest of which contains the documentation and code can be used to compile VC. Right for video conferencing or VOIP helpful friends.)

矩阵的转置、行列式、秩，逆矩阵求法，矩阵的三角分解、qr分解，对称正定矩阵的乔里斯基分解及行列式值，奇异值分解，广义逆的奇异值分解，矩阵特征值与特征向量的各种计算方法(all kinds of computational method of transposition of matrix, determinant, rank, inverse of matrix,triangle decomposition, qr decomposition, cholesky decomposition and determinant value based on symmetry positive definite matrix, decomposition of singular value, decomposition of generalized inversal singular value, eigenvalue and eigenvector)

QR对复数矩阵进行求逆运算，是一个vc动态库源码，源码测试程序中针对是4维复数矩阵采用QR分解方法对4维复数矩阵进行求逆，可扩展，只需修改r上三角矩阵求逆的方法即可(QR method is mainly used for negative complex matrix inversion, the test program is carried out for 4 matrix inversion, scalable, simply modify the triangular matrix inversion process you can)

windows网络编程的工程文件和源代码，主要讲iocp模型的用法，实现一个管理系统。(windows network programming project file and source code, mainly about the use of iocp model, implement a management system.)

在n个城市间以最低的经济代价建设此通信网(N inter-city communication network at the lowest economic cost of construction)

本程序调用了微软自带的mscomm控件，实现com口的数据接收，读者可自行添加发送数据功能。内附mscomm.ocx控件及其注册方法，本程序是用的静态链接库，为的是能在没有vc库的机器上也可以运行，所以个头大了点。(Microsoft's own mscomm controls, I realize com data reception, readers can add their own functions to send data. Enclosing mscomm.ocx control and registration method, the procedure is used in the static link library, for the in the absence of vc for the machine can also run, giving the larger point.)
