问题 I'm trying to write a program that would use 7-Zip DLL for reading files from inside archive files (7z, zip etc). Here's where I'm so far: #include <QtCore/QCoreApplication> #include <QLibrary> #include <QUuid> #include <iostream> using namespace std; #include "7z910/CPP/7zip/Archive/IArchive.h" #include "7z910/CPP/7zip/IStream.h" #include "MyCom.h" // {23170F69-40C1-278A-1000-000110070000} QUuid CLSID_CFormat7z(0x23170F69, 0x40C1, 0x278A, 0x10, 0x00, 0x00, 0x01, 0x10, 0x07, 0x00, 0x00);

问题 I am receiving a service response which is byte[100] how can i convert it to a guid ? byte[] response = wc.UploadValues(url, "POST", nvc); string Guid = new Guid(response).ToString(); Response.Write(Guid); 回答1: There is a Guid constructor which allows you to initialize a Guid from a 16-element byte array. So you will have to first extract the 16 elements from your 100 elements array into a new one and then initialize the Guid. Which 16 elements to extract from your 100 elements array would of

问题 In SQL Server, uniqueidentifier columns can be used like strings with the LIKE comparison: SELECT * FROM dbo.Table WHERE GuidColumn LIKE '4c38e01e%' How can I use this feature in Entity Framework? I want something like this context.Table.Where(x => x.StringColumn.Contains("some string")) but for a Guid column instead for string columns: context.Table.Where(x => x.GuidColumn ???? "4c38e01e") 回答1: As far as I know there is no way to convert Guid to string on the fly in EntityFramework. I'm

问题 How can I get the GUID of the current user in SharePoint 2010 with C#?

You should

问题 My D5 application is on a server being used remotely by a couple of users, so I need use the following function to create a COM object to launch another application (LmPos) installed back on that users PC upon launch: CreateRemoteComObject(const MachineName: WideString; const ClassID: TGUID): IUnknown; rather than creating a local COM object as before: EposServer := CreateOLEObject('POS.Server'); However, the MachineName and ClassID to connect to will depend on which users is launching this

问题 Before asking i searched SO and found this answer which essentially says GUID are predictable and thus should never be used for anything random. But from my understanding i disagree. However this question is about squishing a GUID From my understanding a GUID is made of part MAC address, time and random number. I dont know what part of the GUID is what but this function essentially uses it as 2 64bit ints and XOR them together. I currently use the result as 1) A reset key for people who want

问题 can anyone please tell me the right way to insert values in the rowguid column of the table? I m using sql server management studio 回答1: use the NEWID() function to generate one: CREATE TABLE myTable(GuidCol uniqueidentifier ,NumCol int) INSERT INTO myTable Values(NEWID(), 4) SELECT * FROM myTable or you can set it as a default value: CREATE TABLE myTable(GuidCol uniqueidentifier DEFAULT NEWSEQUENTIALID() ,NumCol int) INSERT INTO myTable (NumCol) Values(4) SELECT * FROM myTable 回答2: You can

问题 As I understand it, Version 1 Guids that relied on timestamps and MAC address, were replaced by Version 4 - more random - in Windows 2000 or thereabouts. What's the easiest way to generate a Version 1 guid from .Net, if I prefer it to a version 4? (I do want the timestamp and (almost) unique machine id to be extractable. I do control the entire environment - I'm ok with privacy/any loss of absolute randomness) Thanks. 回答1: P/Invoke UuidCreateSequential - it returns type 1 guids: For security

问题 We're working with Fluent NHibernate 1.2 and our primary key is a guid saved in a nvarchar(32) column, working with Oracle 11gr2. How can we make this work? (making an automatic conversion...) Thanks ahead, random programmer... UPDATE: forgot to mention, the guid is saved WITHOUT dashes ... 回答1: Update: You will have to implement your own IUserType to handle the dashless Guids.
