How to convert an Integer to LARGE_INTEGER

由 走远了吗. 提交于 2020-06-17 07:15:48
问题 How do i convert an integer to LARGE_INTEGER? For example, when I want to trigger a timer immediately: LARGE_INTEGER zero; zero.QuadPart = 0; KeSetTimer(pTimer, zero, pDpc); Is there any way to convert 0 to LARGE_INTEGER? So I could do this instead: KeSetTimer(pTimer, (SomeType)0, pDpc); I have tried: KeSetTimer(pTimer, (LARGE_INTEGER )0, pDpc); But it doesn't work. I have Googled, but couldn't find any help. 回答1: LARGE_INTEGER is a struct . It is not possible to cast a value to a struct type

问题 For devices attached to my machine I want to retrieve device-property Bus Reported Device Description . For this purpose I use function SetupDiGetDeviceProperty of Setup API. In devpkey.h I found the defintion DEVPKEY_Device_BusReportedDeviceDesc . But if I use DEVPKEY_Device_BusReportedDeviceDesc I receive unresolved external symbol _DEVPKEY_Device_BusReportedDeviceDesc while linking. Here is my code (only included minimal code to reproduce issue): #include "stdafx.h" #include <Windows.h>

Write long to linux char device driver?

由 柔情痞子 提交于 2020-05-31 04:55:32
问题 I'm trying to write a character device driver in linux. Unfortunately it's not working for any numbers greater than 255. I want this driver specifically to work with value of type long . Anytime I input a value greater than 255, the numbers wrong. 256 goes to 0 etc. I've written a simple character device driver that shows the problem, there might be a lot of unused include statements as I copied my full driver and deleted almost everything: chartest.c #include <linux/init.h> #include <linux

Raspberry Pi 4B… Issues with docker not running because of aufs

由 北城余情 提交于 2020-04-30 06:43:32
问题 To begin with I bought a raspberry pi 4b. I installed berry boot on the sd and connected a SSD 480gb. I managed to get it working with a Tv as a monitor hdmi group = 1 etc. I then set up ssh with macbook so I can access my pi with my labtop or use the desktop raspbian. Followed a 4 month old youtube video (relatively new). https://www.youtube.com/watch?v=tx-Hfq5Hc6E I used the commands as follows: //install docker #curl -sSL https://get.docker.com/ |sh //Set up so root isn't used as user -

Legacy Print driver is fuzzy

由 三世轮回 提交于 2020-04-17 22:40:45
问题 We have an old Print driver which takes a document and sends PCL to the spooler. The client then processes this PCL and displays everything as TIFF. Our users have been complaining that the TIFF is fuzzy and the image is not sharp. I am given this stupid task of solving the mystery Is the PCL itself bad. I don't have enough knowledge about a PCL and if it has resolution. How do I trap the output of a driver that's being sent to the spooler? Or is it the client that is somehow not rendering

How can I to transmit at least a “couple of bytes” on the local network (UEFI DXE)

由 ▼魔方 西西 提交于 2020-04-17 22:09:29
问题 I need to write driver (DXE), that can transmit "couple of bytes" from virtual machine (QEMU) to the host system (OS - Ubuntu). I've read the UEFI_Spec and Guide for developers, but I still don't understand, how to write the code and what protocol should I use (tried to use TCPv4 but can't even LocateHandleBuffer). EFI_STATUS Status = gBS->LocateHandleBuffer(ByProtocol, &gEfiTcp4ProtocolGuid, NULL, &HandleCount, &HandleBuffer); I get: EFI_UNSUPPORTED If somebody can explain me or can show

Mac - Showing my service in printers list

由 柔情痞子 提交于 2020-03-06 05:02:49
问题 I created a Mac app/service that will be shown in menu bar (and not in dock) that will take care of printing through my cloud server. What I'm looking is to show this as part of printer list. For example, when a user wants to print a word doc from MSWord, click on Command+P which shows the printer UI where user can select the printer. Now I want to show my app/service as part of the printers list so that the doc can be printed directly using my cloud server. Is it possible to do such thing.

问题 Hí, this mongoDB query, filter documents by date using an idObject field. db.myCollection.find({_id:{$gt: ObjectId(Math.floor((new Date('1990/10/10'))/1000).toString(16) + "000 0000000000000"), $lt: ObjectId(Math.floor((new Date('2011/10/10'))/1000).toString(16) + "000 0000000000000")}}) How would you implement this using the C# driver?

Map a IDDCX_MONITOR to a HMONITOR

由 无人久伴 提交于 2020-02-06 07:57:07
问题 Is there any API that can map an IDDCX_MONITOR to a HMONITOR? Or at least get the RECT of an IDDCX_MONITOR so that I can match it by hands. I know that several IDDCX_MONITORs may have the same RECT therefor point to the same HMONITOR, but it doesn't matter. 来源： https://stackoverflow.com/questions/59773566/map-a-iddcx-monitor-to-a-hmonitor
