VB源码:ASCII码转换器源代码，任意字符的ASCII码转换工具，基于VB6的源代码，可以把任意字符（数字、字母、汉字）转化成ascii码，也可以把ascii码还原成最初的字符。(VB source code: ASCII code converter source code of any character ASCII code conversion tools, based on VB6 source code, you can put any characters (numbers, letters, Chinese characters) into ascii code ascii code can also restore the original character .)

电子标签防碰撞是RFID 系统中一个关键问题。在射频识别系统中．当阅读器作用范围内有多个标签同时向阅读器发送数据时，会产生冲突，必须采用一种防碰撞算法解决这种冲突。在分析典型的二进制及动态二进制防碰撞算法基础上，采用了一种新的防碰撞算法。经实验证明，该算法能有效解决射频识别系统中多目标识别的防碰撞问题。(Tag anti-collision RFID system is a key issue. In the radio frequency identification systems. When the reader within the framework of the role of multiple tags simultaneously send data to the reader, it will create conflict, you must use a anti-collision algorithm to solve such conflicts. In the analysis of a typical binary and dynamic anti-collision algorithm based on the binary, using a new anti-collision algorithm. The experiments show that the algorithm can effectively solve the radio frequency identification system, multi-target recognition of the anti-collision problem.)

说明：  今天给大家带来使用文本文件作为数据源的 ComboBox中国城市三级联动的代码。 1.地区库更新非常方便，不会影响到其他功能（区划代码是唯一的）。 2.文本文件读取来速度很快。(n the past, I used VB6 to write an example of three-level linkage of ComboBox in Chinese cities, using MDB database. A few years ago, the code, the regional database is not the latest. Today we bring you the code of ComboBox, which uses text files as data sources, for three-level linkage of Chinese cities. 1. The regionalization library updates are very convenient and will not affect other functions (regionalization code is the only one). 2. Text files are read very fast.)
