c++实现windows服务程序实例

1、注册服务 ：在 "开始->运行->cmd" 中输入 sc create TEST binPath = "C:\TEST.EXE" 则在windows下注册了一项服务

sc create TestService binpath= "c:\ServiceTest.exe" displayname= "TestService" depend= Tcpip start= auto

注意这里的格式，“=”后面是必须空一格的，否则会出现错误。

在提示建立成功后，可以直接输入“net start TestService”

来启动服务，或者可以直接在“管理工具”的“服务”中直接启动。

C:\Documents and Settings\Administrator>sc create

描述:

在注册表和服务数据库中创建服务项。

用法:

sc <server> create [service name] [binPath= ] <option1> <option2>...

2、启停服务 ：在 "开始->运行->cmd" 中输入"Service.msc"查看该服务状态及开启、停止服务

3、删除服务 ：在 "开始->运行->cmd" 中输入 sc delete TEST

以下是C++语言的一个服务程序编写的实例，编译生成 “C:\ServiceTest.exe“
