说明：  利用VB+SQLserver联合编程制作成为一个唱片店的数据库运营管理系统。本数据库既可以用来客户端登陆选购唱片，也可以用来做数据库后台维护。(Joint programming using VB+ SQLserver produced a record store operation management system database. The database can either be used to purchase the client login record, the database can also be used for background maintenance.)

利用ULN2003A进行驱动，产生PWM波，里边有照片，可供参考，通过本例程了解PWM 的基本原理和使用 (#include <reg52.h> unsigned char timer1 sbit PWM=P1^2 void system_Ini() { TMOD|= 0x11 //PWM TH1 = 0xfe //11.0592 TL1 = 0x33 TR1 = 1 IE =0x8A } main() { system_Ini() while(1) { if(timer1>100) timer1=0 if(timer1<30) PWM=0 else PWM=1 } )

此程序为摄影测量的一个小环节，主要功能是求解影像畸变差，可根据相机内参数求解，简单实用(This program is a small part of photogrammetry, the main function is to solve the differential image distortion can be solved according to the camera parameters, simple and practical)

检查EXCEL文档中某字段的重复值，打开文档，选择相应表格及字段(Check EXCEL document the value of a duplicate field, open the document, select the appropriate forms and fields)

超好用的vb表格小控件， 实现随心所欲的编辑，你值得拥有！(Super use of VB form small controls, you deserve to have!)
