BC_HVAC一个LNC DDE的例程，很值得下载(LNC DDE a BC_HVAC the routine, it is worth downloading)

说明：  U盘过滤驱动系统源代码主要是用DDK来实现的(U disk drive system source code filter is mainly used to realize the DDK)

小区物业管理系统源码,包括系统登陆,数据通信,界面软件编程数据通信等(Residential property management system source code, including the system login, data communication, data communication interface software programming, etc)

利用VC实现的简单双机热备和地址漂移软件,双机均有自身IP, 但只有主机才具备服务IP,当主机中断后,备机可接管服务IP.(A simple tool just like HA software)

根据CPU、磁盘序列号生成注册码程序，为软件版权序列号生成提供了一个方法。(According to CPU, the disk serial number registration code generation program)

程序用于完成多线程程序设计，在vc环境下开发(Procedures for the completion of multi-threaded programming, in vc development environment)

SelfDelete(可以删除自身的VC++源码(巳通过了调试)) 为了实现程序自删除功能，我们可以通过多进程的方法解决这个问题。可执行文件在结束返回前，创建一个运行命令窗口的新进程（在Windows98中为Command进程，在Windows2000/XP中为CMD进程），当然该命令窗口以隐藏方式执行，并通过传递参数执行删除功能。为了避免可执行文件的映像还在内存中就执行删除，需要把当前进程设置为实时优先级，而命令窗口进程设置为很低的IDLE优先级，这样首先可执行文件结束返回，再运行命令窗口的删除命令，就实现了该文件自身的删除功能。 (SelfDelete (you can delete its own VC++ source code (had passed debugging)) In order to achieve the program from the delete function, we can multi-process methods to solve this problem. Return before the end of the executable file, run the command window to create a new process (in Windows98 process for the Command, in Windows2000/XP process for CMD), of course, the command window to hide the manner and to perform delete functions by passing a parameter . In order to avoid the executable file image still in memory on the implementation of delete, you need to set the current process for real-time priority, and the command window to set the process priority to low IDLE, so the end of the first return to the executable file, then run the command window delete command, the file itself to achieve the delete function. )

一个记录开关机时间的软件，可以实现开机自运行(a record time for the switch software can be run in Flint)

读取系统日志，获取开关机时间之后做计算工时(After reading hours to do the calculation system logs for switch time)
