I recently read an article about creating a service program under NT/2000 and translated it as follows to help me understand it. Some of them may not be suitable for translation, I hope my friends who have read this article can help me correct it! (The original post is at the bottom) A Windows Service Program is an EXE (executable program) specially designed to communicate with the SCM (Service Control Manager) of Windows NT/2000 ).

SummaryThe services under Windows NT are similar to the daemon processes under * NIX, and more software are designed as services. After the launch of XP, it is very useful to implement multi-user switching through services.From a security perspective, if we look at WIN's services, there are many topics, such as running permissions and running t

Dispatch source is a basic type in gcd, which is literally called a dispatch source, and its role is to capture these events when there are some specific lower-level system events, and then to do other logical processing, with multiple types of dispatch sources, Listen for system events of the corresponding type, respectively. Let's see what the types are: Ti

Introduction The dynamic loading of device drivers is mainly completed by Service Control Manager (SCM) system components. SCM components can provide many services, such, start, stop, and control services. Write and load the driver, which is mainly used to operate the SCM component. Generally, the following APIs are used to operate the

Create cloudera-scm Since Cloudera Manager and Managed Services use cloudera-scm by default, you need to create this user $ Sudo useradd -- system -- home =/opt/cloudera-manager/cm-5.14.1/run/cloudera-scm-server -- no-create-home -- shell =/bin/false -- comment" cloudera

Grand Central Dispatch, referred to as GCD, is one of the techniques for performing tasks asynchronously.Typically, the code for thread management described in the application is implemented at the system level, and developers simply need to define the tasks they want to perform and append them to the appropriate dispatch queue, GCD can generate the necessary threads and plan to perform the task. This sente

It is very troublesome to control Office controls in Java. With JACOB, things have become much easier. However, it is very troublesome to implement flexible control of Word in Java. Below we will introduce several common WORD objects and some typical processing procedures, and hope to help you. (Note: JDK1.3.2 runs Jacob normally, and JDK1.4 h

First, IntroductionGCD should be the most attractive solution for all multithreaded implementations of iOS, as the GCD itself is the solution Apple proposes for multi-core parallel computing. GCD will automatically utilize more processor cores at work to take advantage of more powerful machines. GCD is the abbreviation for Grand Central Dispatch, which is based on the C language. If you use GCD, the thread is completely managed by the system, we do no
