VC++实现的多线程系统清理程序，可清理系统垃圾文件，使用的是多线程技术，有必要一看，内核仿360的(VC++ implementation of the multi-threaded system cleaning program can clean up the system junk files, using multi-threading technology, it is necessary to look, kernel imitation 360)

串口调试工具，包含自动计算MODBUS crc校验码，是工具非源码(tiaoshi gongju)

说明：  医疗信息管理系统 用vb编写 电子处方、药房管理等 (medical information management system used to prepare vb electronic prescriptions, pharmacy management, etc.)

操作EXCEL的一个类 可以通过VC操作EXCEL 包括各种功能(EXCEL operation of a class can include a variety of functions VC operation EXCEL)

说明：  在Windows操作系统中，任务是有优先级的，本程序演示了不同的线程按照优先级来运行。(In the Windows operating system, the task is a priority, the program demonstrated a different thread to run in accordance with priority.)

程序功能： 1.快速启动应用程序，主要是使用热键。还可以让程序定时启动。 2.锁定计算机。在98下面完全奏效，在2000xp下面不能完全有效。支持定时锁定、启动锁定。 3.定时提醒。 4.关机 5.关闭由本程序启动的子进程，并可以查看他们的进程信息。 6.保护本程序不被非法关闭。 FastRun.exe：主应用文件 Frpo.exe：后台保护程序 msgdll.dll：导出一个自己画的messagebox的动态连接库(procedures functions : 1. Quick Start applications, primarily using hotkey. It can also allow the procedure regularly launched. 2. Lock computer. 98 Below in Congress, in 2000 xp below not completely effective. Support regular lock, lock activated. 3. Timing reminded. 4. Off 5. Close by the commencement of the children, and can view their information process. 6. Protection of the procedures are not being closed. FastRun.exe : main application files Frpo.exe : background msgdll.dll protection program : a painted himself derived messageBox the Dynamic Link Library)

the examples of c codes.it is very easy,but the basic is important(the examples of c codes.it is very easy. but the basic is important)

说明：  呼叫阻塞率的计算和仿真：在时间轴上考虑。无论阻塞与否，下一呼叫到达时刻为当前呼叫到达时刻加上服从参数为1/λ的指数分布的呼叫间隔时间。一个呼叫到达时只需要判断呼叫的到达时刻和各个信道服务完成时刻的先后：如果前者比后者中任意一个大，说明至少有一个信道服务完成时刻比此呼叫到达时刻早，即此信道空闲，此时呼叫成功，应该先把此信道下一个服务完成时刻置为当前呼叫到达时刻，再加上服从参数为μ的指数分布的服务时间；反之，如果前者比后者中全部都小，说明所有信道在此呼叫到达后才会结束服务，即当前忙，此呼叫被阻塞掉了(call blocking probability calculation and simulation : the time frame to consider. Whether or not blocked, the next call arrived at the present moment to call time arrived with a subordinate parameters/ index distribution of the call interval. A call arrived only judgment call and the arrival time each channel service has completed a moment : If the former than the latter an arbitrary, and at least one channel is completed service calls than this moment arrived moments earlier, that this channel is idle, call this success, should first get here Channel a moment of complete services for the current call home arrival time, coupled with the parameters obey the exponential distribution services; Conversely, if the former than the latter, all small, with all the Channel call arrived only aft)
