一款用wpf画柱状图，扇形图，折线图，开发环境为Visual Studio 2013(A painting by wpf histogram, pie charts, line charts, development environment for Visual Studio 2013)

基于Skyline的c#二次开发程序2-DynamicObject(Based on Skyline' s second development program c#)

VS2010做完用户、角色、权限后的代码，SQL数据库。界面挺漂亮。BS三层架构(The VS2010 finished code, SQL database users, roles, permissions. Interface pretty)

该程序的主要功能是实现在STM32上数字示波器的实现，可以显示频率，幅值。(The main function of this program is to achieve the STM32 implementation of the digital oscilloscope can display the frequency, amplitude.)

本文件讲述了基于CMC芯片的智能仪表的采集器、控制器的源代码描述。(This file tells the story of the intelligent instrument based on CMC chip collector, controller source code description. )

在给定字符串中找出单词（ “单词”由小写字母字符大写字母和构成，其他非字母字符视为单词的间隔， 如、问空格号、数字等等；另外单个字母不算单词）；找到单词后，按照长度进行降序排序， （排序时如果长度相同，则按出现的顺序进行排列），然后输出到一个新的字符串中；如果某个单词重复出现多次， 则只输出一次；如果整个输入的字符串中没有找到单词，请输出空串。输出的单词之间使用一个“空格”隔开， 最后一个单词后不加空格。(Identify the word (" word" character from the uppercase and lowercase letters constituted, other non-alphabetic characters as word spacing, such as asking a space number, number, etc. another is not a single letter word) in a given string find words after descending order according to length, (if the same length, the order stated that appears when sorting arranged), and then output to a new string If a word is repeated several times, only output once If the entire input string is not found in word, outputs an empty string. Used between the output of a word " space" separated, no spaces after the last word.)

说明：  本程序利用C++产生随机数，每次产生的随机数都不一样(This program uses C ++ to generate random numbers, the random numbers generated each time are different)

TREE控件代码。已在本机调试好。可以使用。数据库为ACESS。(TREE control code. Has been good on the local debugging. Can be used. Database for ACESS.)
