这是一个vb与s7200PLC自由口通讯的类模块，我自己工程中可以直接使用。它使用的通讯方式是西门子PLC的自由口通讯技术实现。在工程开发中有不错的表现，希望大家提出宝贵的意见。

这是我收集的几个通信基础理论的Matlab仿真实现，包括bpsk、qpsk、ofdm以及信号衰减和延迟的仿真。尽管不是我本人原创，但比较都经典。-This is my collection of several communications infrastructure theory Matlab Simulation, including BPSK. QPSK, and the OFDM signal attenuation and delay in the simulation. Although it was not my original, but more are classics.

CryptoAPI的演示程序，可以进行测试。多联系，非常感谢。-CryptoAPI demo program can be tested. More links Thank you very much.

pl/sql的综合运用上例用到的oracle里关于游标的几个内置函数:％isopen,％notfound,％rowcount。 隐式游标更多用在for loop中，你不用再手工去open，fetch或是close游标，非常方便-pl/sql integrated the use of oracle used in Example cursor on several built-in functions: isopen, notfound, rowcount. Implicit cursor more used in for loop, you no longer have to manually open, fetch or close the cursor, a very convenient

这是一个简单的聊天工具，功能还是很强的，有不足之处，还需共同学习-This is a simple tool for chatting, or highly functional, is not perfect, we must learn together

这是我最近在VC平台下编写的一个与LINUX平台通讯的IRDA程序，在运行此程序前一定要先下载一个SDK，这是VC下IRDA通讯所必须的。-This is my recent VC prepared under a Linux platform with the IRDA communication procedures, Run this program in the former must first download an SDK, which is VC IRDA communication requires.
