本人个人开发项目中用到的，用一个文本框，动态的显示数据库特定项目的数据，实时刷新，而不用刷新整个窗体

＃制作了一个类似Windows中的计算器。本计算器的基本功能如下： １实现了计算器的基本功能：加、减、乘、除 ２实现开平方根 ３实现清除屏幕 ４实现了清除内存 ５实现了对屏幕数据的复制和粘贴-# produced a similar Windows calculator. The basic functions of the calculator is as follows : a realization of the basic functions of the calculator : addition, subtraction, multiplication and square root of two open three to achieve removal of the screen to achieve the removal of four memory to achieve realization of the five screens of data copying and pasting

基于stm32的单相全桥整流电路，电源类(Single-phase rectifier circuit based on STM32,)

车位数由用户输入，车能够进入车场，车场满时车再进来就要进入便道，然后车离开车场时需要根据车在车场停留的时间收费，收费标准是由用户输入的，如果是车场满时出车后，便道上的车就可以进入车场。需要时要显示车场的所有车的信息状况，包括车的到来时间，进入车场的时间，所在车位置或便道位置。(Parking spaces from user input, vehicles can enter the yard, full yard car will be re-entered into the sidewalk, and then leave the car when the car needs to stay under the car in the garage to collect the tolls, charges are entered by the user, in the case of car full turnout, the pavement on the car will be able to enter the yard. Necessary to show all the car parking lots of information, including the arrival of vehicles into the yard of the time, where the location of vehicle location or shortcut.)
