问题 I am just starting out with driver development, and am trying to initialize a device driver through the operating system on start up. The driver is for Windows Embedded CE 6.0. I have been attempting to have my device send a message through a serial port to my PC whenever it gets initialized. DWORD MYD_Init(LPCTSTR pContext, LPCVOID lpvBusContext) { DWORD dwResult = 1; RETAILMSG(TRUE, (TEXT("MyDriver: Initializing!\n"))); DEBUGMSG(TRUE, (TEXT("MyDriver: Initializing!\n"))); return dwResult; }

问题 I know these types of questions are already there but provided solution is not working for me.In my application there is no version mismatch b/w driver and PostgreSQL server.

问题 I am migrating my Database from MSSQL to Aurora(MYSQL). The application is using .net and NHibernate. We tried the Nhibernate driver for MYSQL "MySql.Data" and it works fine for all use cases but failover. When a failover happens, the connection is not reset and it keeps trying to connect to the old IP from the writer cluster and so all the write call fails with the exception "The MySQL server is running with the --read-- only option so it cannot execute this statement". This only gets

问题 Can one use IoCallDriver() with an IRP created by IoBuildAsynchronousFsdRequest() on a device object returned by IoGetDeviceObjectPointer()? What I have currently fails with blue screen (BSOD) 0x7E (unhandled exception), which when caught shows an Access Violation (0xc0000005). Same code worked when the device was stacked (using the device object returned by IoAttachDeviceToDeviceStack()). So what I have is about the following: status = IoGetDeviceObjectPointer(&device_name, FILE_ALL_ACCESS,

问题 I am trying to create a state diagram of a submitted spark application. I and kind of lost on when then an application is considered FAILED. States are from here: https://github.com/apache/spark/blob/d6dc12ef0146ae409834c78737c116050961f350/core/src/main/scala/org/apache/spark/deploy/master/DriverState.scala 回答1: This stage is very important, since when it comes to Big Data , Spark is awesome, but let's face it, we haven't solve the problem yet! When a task/job fails, Spark restarts it

问题 After reading a little, I am concerned that my 32-bit Delphi application will not be able to use libusb 64-bit driver on Windows 7 and other 64-bit Windows systems, and that it will not be able to talk to my custom hardware device on those systems. Is this true? If yes, is there some workaround? Am I missing something in this picture? 回答1: On libusb 1.0 with the WinUSB backend (Microsoft driver included with windows) we have no problem to communicate with it from an x86 app (Managed c++

问题 According to the definition, A file system filter driver is an optional driver that adds value to or modifies the behavior of a file system. A file system filter driver can filter I/O operations for one or more file systems or file system volumes. Depending on the nature of the driver, filter can mean log, observe, modify, or even prevent. I want to write a filter driver for Linux which will intercept all read requests to an ext4 partition and redirect a few of them based on some application

问题 I know volatile keyword prevents compiler from optimizing a variable and read it from memory whenever it is read. Apart from memory mapped registers, what are all the situations where we need to use volatile? Given a conforming compiler, do I have to declare test_var as volatile in both scenarios? 1. In file1.c int test_var=100; void func1() { test_var++; } In file2.c extern int test_var; void func2() { if(test_var==100) { .... } } 2. In file1.c int test_var=100; void func1() { } In file2.c
