基于VFP的出题小系统，以前做的，传上来分分享一下(Test system based on VFP, before doing, Chuan up points to share)

说明：  德卡读卡程序，与D8读卡器相匹配，能够对MIFARE系列的卡进行操作(Deka card reader program, matched with D8 card reader, can operate MIFARE series cards)

说明：  VFP开发的主控程序，其中用了多种方法和技巧实现对用户权限的控制和选择。(VFP development of the control procedures, which use a variety of methods and techniques to achieve competence of the user control and choice.)

dbf filter sample I found and very useful for dbf database programing

VB编写的退税管理系统，可做毕业设计参考，很适用！(VB prepared the tax rebate management system, can be graduated from the reference design, it is applicable!)

Handling null fields in SQL queries

ALTER TABLE and CREATE TABLE in Access/vb6

1. 采用BP神经网络设计男女生分类器。采用的特征包括身高、体重、是否喜欢数学、是否喜欢文学、是否喜欢运动共五个特征，BP神经网络包含一个隐层，隐层结点数为5。要求：自行编写代码完成后向传播算法，采用交叉验证的方式实现对于性能指标的评判（包含SE,SP,ACC和AUC，AUC的计算可以基于平台的软件包）。(. using BP neural network to design the classifier for male and female students. The features include height, weight, whether they like mathematics, whether they like literature, and whether they like sports. The BP neural network contains a hidden layer, and the number of hidden nodes is five (5). Requirements: self compiled code, post propagation algorithm, cross validation method to achieve performance evaluation (including SE, SP, ACC and AUC, AUC calculation can be based on platform software package).)
