driver

问题 I am an individual, not a company. I am well aware that I can test sign a driver and run in test mode. However myself and the other person on the project are interested in getting our module signed. Question is: it looks like verisign requires you to be an actual business. Is there anyway we can get a signature through globalsign or something? As an individual developer. Under the windows 7 x64 OS? Or is it just a big screw you to the individual? 回答1: Why not register a sole proprietorship

问题 The situation is that I have a user space file system which can provide a bunch of posix like interface in user space. Like this: open read write mkdir ... I want to make a volume on this file system and pass it to a docker. My question is how can I control the way docker access this volume so that it can be redirected to my posix like interface? Right now my file system can't be mounted on the host. It is a completely user space file system. I think fuse can support this, but I don't want to

问题 being a dbExpress newbie I wonder if there is a dbExpress driver for Microsoft Access? 回答1: I think the only way to connect to Access is by using ADO. (TADOConnection). 回答2: I have had good results using the open source dbxoodbc driver for dbExpress. The download has several demo projects that use access databases, so you should be able to get up and running in no time. You can find it at http://sourceforge.net/projects/open-dbexpress/ I have only tried it with older versions of access, so I

问题 I have a web development project using local install of Tomcat 7 . I am trying to connect to SQL Server 2012 using Microsoft's driver for jdbc ( sqljdbc41.jar ). The sqljdbc41.jar is in my application build path: and I am exporting it. Furthermore, in the Tomcat application directory lib folder I have also placed a copy of sqljdbc41.jar . There are no compile errors, but at runtime when I try to load the SQL Server driver I get the following: ClassNotFoundException - com.microsoft.jdbc

问题 I am getting this error when I am trying to build my driver: Driver.cpp(7): fatal error C1083: Cannot open include file: 'ntddk.h': No such file or directory I am using Visual Studio 2012 with WDK 8.1 installed (I have not cinfigured anything in VS). Any help is appreciated. 回答1: Go to project properties -> C/C++ -> General, and add ddk headers path to Additional Include Directories tab. It should be sth like $(WDKPATH)\inc\ddk where $(WDKPATH) is ofc a directory where You have installed WDK.

问题 EDIT #4: I figured out that I shouldn't be assigning the attr_groups to the groups field in the driver field of the struct platform_driver structure. Look for the comment /* WRONGO: should not be assigned here. */ below. I haven't figured out where I should be assigning it yet ... My code for a platform driver manages to cause a Kernel "OOPS" when reading a sysfs attribute because of a NULL reference. I'm sure it is a simple oversight in the following code, but I can't see it: ... static int

问题 Is there a way to create a user-mode process from kernel-mode on Windows NT platform (XP-W7)? EDIT: I must install only the driver. This is a specific of the project. 回答1: To create a valid win32 process the driver must communicate with CSRSS (what is completely undocumented). So I ended up by queuing a user-mode APC and allocating virtual memory for the APC code in the context of the existing win32 process (that code will call CreateProcess and do the job). It is a tricky way but it works.

问题 I'm been trying to get into driver development (queue the "don't do that") I have been looking at this msdn page and after installing the WDK (Windows Driver Kit) 10 I am still unable to compile the example that they use on that page. I have looked at other SO questions but I am unable to find the installed directory of the WDK. When I attempt to run the setup I am greeted by this: How can I solve this? 回答1: You need to add WDK headers path to your vcxproj include directories: vcxproj

问题 Here's the code raising the exception: public static class NHibernateSessionManager { private static ISessionFactory sessionFactory = new Configuration().Configure().BuildSessionFactory(); public static ISession GetSession(string clientId) { if (ContextSession == null) ContextSession = sessionFactory.OpenSession(new OracleIntercerptor(clientId.ToUpper())); else ((OracleConnection)ContextSession.Connection).ClientId = clientId; return ContextSession; } // - snip - } and the call to the code

问题 In Apache Spark program how do we know which part of code will execute in driver program and which part of code will execute in worker nodes? With Regards 回答1: It is actually pretty simple. Everything that happens inside the closure created by a transformation happens on a worker. It means if something is passed inside map(...) , filter(...) , mapPartitions(...) , groupBy*(...) , aggregateBy*(...) is executed on the workers. It includes reading data from a persistent storage or remote sources
