How to import users in CRM 2011 with source GUID

由 ◇◆丶佛笑我妖孽 提交于 2020-02-07 03:08:02
问题 We have three Organization tenents, Dev, Test and Live. All hosted on premise (CRM 2011. [5.0.9690.4376] [DB 5.0.9690.4376]). Because the way dialogs uses GUIDs to refference record in Lookup, we aim to maintain GUIDs for static records same across all three tenents. While all other entities are working fine, I am failing to import USERS and also maintain their GUIDS. I am using Export/Import to get the data from Master tenent (Dev) in to the Test and Live tenents. It is very similar to what

Qt实践录：串口调试助手

由于项目需要使用到串口调试及测试，为了练手，使用 Qt 编写一个串口调试助手。本文按开发的过程进行简单介绍，同时也涉及部分用到的模块代码。详细代码参考源码仓库。 工具特性 具体功能 具备串口收发功能。 串口参数设置。默认115200,N，8，1 接收区清空，接收区十六进制显示，接收区时间戳。 发送区清空，十六进制发送，自动追加 \r\n ，定时发送。 收发计数显示及清零。 串口设备自动检测。运行前串口就绪则自动打开。运行中串口插入不会自动打开。运行过程中拔出设备则自动关闭串口。 已知 Bug 接收区时间戳显示不完善。 串口发送大量乱码时，程序会崩溃。乱码可能是真的乱码，也可能是波特率错误设置。 Qt 相关知识 MainWindow设计。 Qt串口类。 常用控件：按钮、复选框、文本编辑框、控件贴图。应用程序logo。 Qt 检测设备热插拔（Windows）。 开发过程 工程相关 Qt 使用的串口类为 QSerialPort ，需要在工程文件中添加对应的库，如下： QT += core gui serialport logo图标，注意是 ico 格式： RC_ICONS = images/logo.ico 图片资源文件： RESOURCES += \ images.qrc USB 设备检测依赖的库： win32: LIBS += -lSetupAPI -luser32 信号与槽 在

Platform-independent GUID generation in C++?

由 a 夏天 提交于 2020-01-27 03:24:48
问题 What is the best way to programmatically generate a GUID or UUID in C++ without relying on a platform-specific tool? I am trying to make unique identifiers for objects in a simulation, but can't rely on Microsoft's implementation as the project is cross-platform. Notes: Since this is for a simulator, I don't really need cryptographic randomness. It would be best if this is a 32 bit number. 回答1: If you can afford to use Boost, then there is a UUID library that should do the trick. It's very

How should I store GUID in MySQL tables?

由 前提是你 提交于 2020-01-26 08:07:21
问题 Do I use varchar(36) or are there any better ways to do it? 回答1: My DBA asked me when I asked about the best way to store GUIDs for my objects why I needed to store 16 bytes when I could do the same thing in 4 bytes with an Integer. Since he put that challenge out there to me I thought now was a good time to mention it. That being said... You can store a guid as a CHAR(16) binary if you want to make the most optimal use of storage space. 回答2: I would store it as a char(36). 回答3: Adding to the

Guid with extra characters issue

由 ╄→尐↘猪︶ㄣ 提交于 2020-01-24 04:27:07
问题 I have a table named Student , contain a column StudentId as GUID , so I used the Uniqueidentifier datatype for that. If I want to get particular record, I get the result by the below query: SELECT * FROM Student WHERE StudentId = '919C3BF9-B081-458C-897D-C0B3FF56AF73' It returns the expected result. But in case if I mistakenly add any extra characters in the end also, it returns the same result. Like the below query: SELECT * FROM Student WHERE StudentId = '919C3BF9-B081-458C-897D

Guid.NewGuid(); behind the scenes in .NET Core

由 杀马特。学长 韩版系。学妹 提交于 2020-01-22 20:12:22
问题 Researching the subject yesterday, I found several interesting questions (such as this one) on how GUIDs are ultimately generated. In brief; it seems that Guid.NewGuid(); calls CoCreateGuid in the COM, which in turn calls UuidCreate in the Windows RPC (docs here and here). I found myself wondering; How does this work when the OS is not Windows, such as might be the case with .NET Core, and does this affect the 'version' algorithm used to generate the GUID (which I understand is Version 4 on
