学习VC++时做得小练习，基于单文档应用的简单的数据库编程，易于出血者的使用，实现最基本的数据库管理功能-learning VC when doing small exercises, based on the application of the single-file database programming simple and easy to use bleeding, achieve the most basic database management functions

非常好的管理类软件，各种功能非常齐全，欢迎使用！！！(Very good management class software, various functions are very complete, Welcome! ! !)

异形按纽，绝对异型-square button absolutely abnormal

Road Point Navigation, which allows objects to move along path points by creating road points

1-100之间有多少个素数，并输出所有素数及素数的个数。 ???? 程序分析：判断素数的方法：用一个数分别去除2到sqrt(这个数)，如果能被整除，则表明此数不是素数，反之是素数。(How many prime numbers are there between 1-100 and output all prime numbers and prime numbers. The method of judging prime number: 2 to sqrt (this number) is removed by one number, and if it can be divided, the number is not prime, and vice versa.)

说明：  线性矩阵不等式求解的一个例子，通常用于系统控制中用来求未知矩阵(Solution of Linear Matrix Inequality)

说明：  创建一个计时测试程序，比较公式节点和本地LabVIEW数学函数的平均执行时间。此程序需要一个For循环或一个平序或叠序结构以及一个Case结构。要求For循环运行计时测验N次，然后使用Statistics Express VI对结果做平均。要求顺序结构在代码运行之前以及代码运行之后对Tick Count进行采样。要求Case结构判定用户是要执行公式节点还是要执行本地LabVIEW数学函数。对每个分支运行计时测验程序。哪种方法执行时间最快？哪种方法最容易编程？别人要看程序时，哪种方法更容易理解？(Create a timing test program to compare the average execution time of formula nodes and local LabVIEW mathematical functions. This program needs a For loop or a plain or overlapping structure and a Case structure. Require the For cycle to run the timing test N times, and then use Statistics Express VI to average the results. The sequential structure is required to sample Tick Count before and after the code runs. The case structure is required to determine whether the user wants to execute formula nodes or local LabVIEW mathematical functions. Run the timing test program for each branch.)

说明：  省市区三级联动数据，适用于使用VANT的程序；也可自己独立开发(Provincial and urban three-level linkage data, applicable to the use of VANT procedures; can also be independently developed.)
