DataAdapter
使用DataAdapter对数据库进行操作
将SQL-search.aspx程序可改为使用DataAdapter对数据库进行操作.
程序使用"Dim objAdapt As New OleDbDataAdapter(strcmd,objCon)"创建了DataAdapter对象。(Use DataAdapter to operate the database
The SQL-search.aspx program can be changed using the DataAdapter to operate the database. The program uses "Dim objAdapt As New OleDbDataAdapter (strcmd, objCon)" Creating a DataAdapter object.

ucosii51
这是一个用51单片机系统仿真ucosii工作的protues电路
本系统包括扩展64k RAM的单片机系统和杨屹移植到51单片机的ucosii 系统
使用方法：
1.安装Protues7.4版，然后用protues打开protues 8051 simulation 文件夹
中的extern ram.DSN 文件
2.打开extern ram.DSN 后，双击单片机在弹出的窗口中的Program File 选项 中选择yy.hex文件。
(yy.hex其实就是yy文件夹中keil文档编译出来的hex文 件，yy文件夹是杨屹的ucos51 系统，用keil 2
可以打开)
3.在Clock Frequency选项中输入22.184M(杨屹的ucos51 用的是22.184M hz的单片机频率)
4.双击VTERM串口调试显示屏，在Baud Rate 选项中选择19200的波特率
5.保存，点击运行就可以看到经典的hello world 了。
(1. Protues7.4 version installed, and then open the protues folder protues 8051 simulation
The extern ram.DSN file
2. Open extern ram.DSN, double-click the pop-up window of SCM in the Program File option, select yy.hex file.
(yy.hex actually yy folder keil out of the document compiled hex files, yy folder is Yang Yi s ucos51 system, using keil 2
Can open)
3. In the Clock Frequency option to enter 22.184M (Yang Yi of the ucos51 using a microcontroller 22.184M hz frequency)
4. Double-click VTERM serial debug display, in the Baud Rate select 19200 baud rate options
5. Save, click Run you can see the classic hello world)

Stepper-motor-drive-source
步进电机28BYJ48型四相八拍电机，电压为DC5V—DC12V。当对步进电机施加一系列连续不断的控制脉冲时，它可以连续不断地转动。每一个脉冲信号对应步进电机的某一相或两相绕组的通电状态改变一次，也就对应转子转过一定的角度（一个步距角）。当通电状态的改变完成一个循环时，转子转过一个齿距。四相步进电机可以在不同的通电方式下运行，常见的通电方式有单（单相绕组通电）四拍（A-B-C-D-A。。。），双（双相绕组通电）四拍（AB-BC-CD-DA-AB-。。。），八拍（A-AB-B-BC-C-CD-D-DA-A。。。）(Stepping Motor 28BYJ48 four-phase eight-phase motor, the voltage DC5V-DC12V. When a series of continuous control pulses are applied to the stepper motor, it can be continuously rotated. Each pulse signal corresponds to the stepper motor of a phase or two-phase winding power state change once, also corresponds to the rotor through a certain angle (a step angle). When the change in the power-on state completes one cycle, the rotor turns one pitch. Four-phase stepper motors can be operated in different power-up modes. The common power-up modes are: single-phase winding power (ABCDA ...), double (dual-phase winding)-DA-AB-...), eight beats (A-AB-B-BC-C-CD-)
