原来的代码是VS2010编译的，现升级为VS2013后出现VS2013errorMSB8031:BuildinganMFCprojectforanon-Unicodecharactersetisdeprecated。
.YoumustchangetheprojectpropertytoUnicodeordownloadanadditionallibrary.Seehttp://Go.microsoft.com/fwlink/p/?LinkId=286820formoreinformation.摸索了好久终于解决了，最佳解决方法如下：1、下载vc_mbcsmfc.exe2、关闭vs2013，然后安装vc_mbcsmfc.exe3、打开vs2013，点击项目-＞属性-＞常规（里面的）-＞字符集然后选择使用使用多字节字符集。
然后重新生成解决方案你就会惊喜的发现成功了

SharpSCADA-工控网关,轻量级组态软件.===================简介-------------采用技术：开发语言：C#运行环境：.NETFramework数据库：SQLServer功能：-------------*1.轻量级工控网关：支持当前几种主要的工业协议如西门子的Profinet、AB的EtherNetIPs、施耐德的Modbus和OPC。
采用类OPC接口网关。
*2.数据采集、归档、预警及配置工具支持实时数据采集、历史数据归档、变量触发预警，并使用TagConfig工具简单的配置实现。
*3.人机界面（设计时和运行时）*设计时：采用MicrosoftVisualStudio+设计器插件（在VS2010-VS2015社区版测试通过）。
通过继承HMIControlBase接口并书写极少量的代码即可实现复杂的图元组件。
支持图元拖放、组合、连线、变量绑定及编辑功能。
*运行时：MicrosoftVisualStudio编译运行为可执行文件。
环境准备-------------Windows：支持的操作系统：Windows7/8/10/Server2008.NETFramework4.0/4.5/4.6SQLServerExpress2014/2008项目安装-------------下载最新版本，解压后:*1.可直接打开项目工程文件测试源代码：..\SCADA\Program下运行DataExchange.sln（支持VS2010-2015各版本）*2.可运行可执行文件测试：Server端测试：在目录..\SCADA\Program\BatchCoreTest\bin\Debug下运行BatchCoreTest.exeClient端测试：在目录..\SCADA\Program\CoreTest\bin\Debug下运行CoreTest.exe请参考Document文件夹中的教程：《部署流程》和《设计流程》，如有问题可参考《FAQ》文档。
QuickStart-------------*1.还原数据库*2.修改配置文件并复制到C盘根目录下*3.修改数据库内驱动程序的路径*4.运行DEMO具体流程可参看《部署流程》。
开发工具推荐-------------VisualStudio/Blend：做为组态设计器，推荐VS2010，VS2015版本。
项目结构-------------驱动程序目前支持：*已发布：内存数据库ModbusTCP/RTU、OPCDA、SiemensS300/200/1200/1500、Panasonic、OmronUDP*后续发布：DDE、ABEtherNetIP、Mitsubishi文件目录-------------*Database目录[存放数据文件]：db2014.bak文件为SQLServer2014数据备份文件。
db2008.bak文件为SQLServer2008数据备份文件。
test.opf为Kepserver4.5数据文件（可通过该软件还原为变量表）。
两个csv文件为两组变量。
*DataConfig目录[存放配置文件]：host.cfg为主配置文件，第一行为网关服务器名/IP地址。
如在本地测试，按默认lochost即可。
client.xml为客户端配置文件。
server.xml为网关服务配置文件。
*dll目录[存放驱动程序及第三方组件]：如OPCDriver即为OPC通讯组件。
Dynamicdatadisplay：开源归档数据显示组件，http://dynamicdatadisplay.codeplex.com/WPFToolkit：WPF开源扩展工具包，http://wpftoolkit.codeplex.comlibnodave：西门子驱动开源库(https://github.com/netdata/libnodave)*TagConfig目录[存放配置工具]：可方便配置驱动、组、变量、报警、量程等信息。
支持导入导出。
*Program目录[存放源代码]：BatchCoreTest工程为网关服务器测试代码（控制台显示）。
BatchCoreService工程同BatchCoreTest，但可编译为Windos服务。
DataService工程为框架及主要接口组件。
CoreTest工程为样例文件。
包含一系列界面元素。
HMIControl工程为图元组件。
可支持工具栏拖放。

最近在学modbus通讯，整理了大批资源代码，肯定让你满意，包含c#、c++、mfc、c的各类基本、有难度的代码，modbustcp/rtu和tcp等，也有modbus的类库及仿真软件，过段时间，我会再整理内容写篇博客，并且把整理好注释的代码提供到博客里，到时候写好望大家交流提点意见。
若觉得积分不值，可退。

在日常工作中，钉钉打卡成了我生活中不可或缺的一部分。然而，有时候这个看似简单的任务却给我带来了不少烦恼。 每天早晚，我总是得牢记打开钉钉应用，点击"工作台"，再找到"考勤打卡"进行签到。有时候因为工作忙碌，会忘记打卡，导致考勤异常，影响当月的工作评价。而且，由于我使用的是苹果手机，有时候系统更新后，钉钉的某些功能会出现异常，使得打卡变得更加麻烦。 另外，我的家人使用的是安卓手机，他们也经常抱怨钉钉打卡的繁琐。尤其是对于那些不太熟悉手机操作的长辈来说，每次打卡都是一次挑战。他们总是担心自己会操作失误，导致打卡失败。 为了解决这些烦恼，我开始思考是否可以通过编写一个全自动化脚本来实现钉钉打卡。经过一段时间的摸索和学习，我终于成功编写出了一个适用于苹果和安卓系统的钉钉打卡脚本。
