问题 In "MDbg Sample.zip" projects, invoke the function from COM Module as: [ComImport, Guid("3D6F5F61-7538-11D3-8D5B-00104B35E7EF"), InterfaceType((short) 1)] public interface ICorDebug { ... } The question is where to find the Guid("3D6F5F61-7538-11D3-8D5B-00104B35E7EF"), i can not find it in the regedit, but how to connect the ICoreDebug interface with the COM module? 回答1: It's not in the registry. That guid is the IID, ICorDebug doesn't support remote access so there is no reason to register a

WCF Service called too soon in WebForm?

由 自古美人都是妖i 提交于 2019-12-25 03:32:31
问题 I'm having an odd issue where it seems my WCF service is being called too soon when called from inside a WebForms event handler. Specifically, the Guid being passed to the service call is all zeros, as if it hasn't been created yet... When I fire up the debugger and put a watch on the guid variable, I can see that it indeed is being created as a valid, non-zero Guid. Here's the code: protected void button_click(object sender, EventArgs e) { var title = titleTextbox.Text; var guid = Guid

Alternatives to GUID for clustered index

由 好久不见. 提交于 2019-12-25 01:46:40
问题 I have the following situation: I'm creating a database that will work locally, but can be migrate to a online database that have the same schema and will already have some data. For this reason, I'm planning to use GUIDs as the primary keys for it's tables, as it will make migrations easier by avoiding the need to change primary key values (and cascading it to referencing tables) that would occur if I use any identity column (am I right?). The database is build on SQL Server 2012. Despite

How can I convert a UUID to a string using a custom character set in Ruby?

问题 I want to create a valid IFC GUID (IfcGloballyUniqueId) according to the specification here: http://www.buildingsmart-tech.org/ifc/IFC2x3/TC1/html/ifcutilityresource/lexical/ifcgloballyuniqueid.htm It's basically a UUID or GUID (128 bit) mapped to a set of 22 characters to limit storage space in a text file. I currently have this workaround, but it's merely an approximation: guid = '';22.times{|i|guid<<'0123456789ABCDEFGHIJKLMNOPQRSTUVWXYZabcdefghijklmnopqrstuvwxyz_$'[rand(64)]} It seems best

C#制作ActiveX浏览器插件.net

由 霸气de小男生 提交于 2019-12-24 22:43:35
开发环境：VS2008 第一步 创建项目 新建一个项目，选择“Windows窗体控件库”，创建一个用户控件项目“ActiveXDemo”（注意，这里起名不能用中文，否则后面会出问题），里面有个用户控件类UserControl1.cs 在类中写上你自己需要的业务逻辑代码，保存 第二步 设置项目属性 在AssemblyInfo.cs里添加[assembly: AllowPartiallyTrustedCallers()]，需要引用using System.Security;命名空间 设置项目属性，右键项目——属性 选择“应用程序”，点开“程序集信息” 勾选“使程序集COM可见”，点“确定” 然后选择“生成”，滚动拉倒底部，勾选“为COM互操作注册” 然后保存，重新编译项目，至此，此时的“ActiveXDemo.dll”就成了一个ActiveX控件 第三步 安装外部工具 安装外部工具“OLE/COM对象查看器”和“创建GUID”（已有这两款工具的可以忽略此步骤） 1.OLE/COM对象查看器 这款工具是用来查看ActiveX控件的，也就是验证你的项目有没有成为一个ActiveX控件 安装方法：点开VS顶部菜单栏“工具”——“外部工具” 然后，添加一个“OLE/COM对象查看器”，对应的命令程序一般放在C:\Program Files\Microsoft SDKs\Windows\v6

数据库主键设计

数据库中的主键 我一般采用 GUID，也就是下文中的第5种方式。 这篇文章总结得很全面，我是在CSDN上看到的，现在修改成最初出现的版本了 ：） 原文在： http://tintown.cnblogs.com/archive/2005/03/02/111459.html 数据库主键设计之思考 在我们的数据库设计中，不可逃避的就是数据库表的主键，可能有很多朋友没有深入思考过，主键的设计对整个数据库的设计影响很大，因此我们不得不要重视起来。 主键的必要性 : 有些朋友可能不提倡数据库表必须要主键，但在我的思考中，觉得每个表都应该具有主键，不管是单主键还是双主键，主键的存在就代表着表结构的完整性，表的记录必须得有唯一区分的字段，主键主要是用于其他表的外键关联，本记录的修改与删除，当我们没有主键时，这些操作会变的非常麻烦。 主键的无意义性 ： 我强调主键不应该具有实际的意义，这可能对于一些朋友来说不太认同，比如订单表吧，会有“订单编号”字段，而这个字段呢在业务实际中本身就是应该具有唯一性，具有唯一标识记录的功能，但我是不推荐采用订单编号字段作为主键的，因为具有实际意义的字段，具有“意义更改”的可能性，比如订单编号在刚开始的时候我们一切顺利，后来客户说“订单可以作废，并重新生成订单，而且订单号要保持原订单号一致”，这样原来的主键就面临危险了。因此，具有唯一性的实际字段也代表可以作为主键。因此

Generating GUIDs for Wix MSI files in Azure DevOps

由 巧了我就是萌 提交于 2019-12-24 02:44:08
问题 I am setting up a Wix installer for web server application and for a Sitecore front end application. My question is not specific to web server or Sitecore. My issues are with Wix and how to use it with continuous delivery. 1) Wix requires GUIDs for each file and the product itself. Do I need to update each GUID in the Wix file with every build? In a Git repo, that can potentially be a lot of changes. 2) If I have to update the GUIDs when each branch (dev, staging, and master) on my CD server

Best (most efficient) DataType to use for UUIDs as JPA IDs

由 时光总嘲笑我的痴心妄想 提交于 2019-12-23 18:17:59
问题 I want to use UUIDs as IDs for my JPA Objects. I am currently just using a String to store the UUID. What would be more efficient? 回答1: How are you measuring efficiency? For example, storing the UUID (which is a text encoding of a byte[] ) as a couple of long values will allow you to compare them very quickly on a 64-bit architecture (much more quickly than String comparison, which is character-by-character). However, your coding efficiency would suffer, because you have to write a custom

How can I get the GUID from a PDB file?

由 青春壹個敷衍的年華 提交于 2019-12-23 17:42:47
问题 Does anyone know how to get the GUID from a PDB file? I'm using Microsoft's Debug Interface Access SDK http://msdn.microsoft.com/en-us/library/f0756hat.aspx and getting E_PDB_INVALID_SIG when passing in the GUID i expect when trying to load the PDB. I'd just like to know the GUID of the PDB so I can be certain that it's mismatching and not just a PDB that's perhaps corrupted somehow. Is there a tool that can do this? I've tried dia2dump and dumpbin, but with no joy... Many thanks, thoughton.
