Win8上Service程序及外部App调用此Service
一.Service
借助MSDN上Win7 Service的Demo和《用VC++建立Service服务应用程序》,在Win8上经历各种磨难,终于跑起来自己改装的服务程序了。
原来API基本没变,我所困惑的是Win7上直接运行都没有问题,在Win8上不可以。
报错:
OpenSCManager failed w/err 0x00000005
原来是Win8上权限的问题,也许我自己的Win7一启动就拥有了Admin权限吧。
下面直接进入正题,我整合了一下代码,共三个文件:main.c,Service.h, Service.cpp。(项目是控制台程序。)
main.c只是程序的入口,运行时接受参数。
#pragma region "Includes" #include <stdio.h> #include <windows.h> #include "Service.h" #pragma endregion int wmain(int argc, wchar_t* argv[]) { if ((argc > 1) && ((*argv[1] == L‘-‘ || (*argv[1] == L‘/‘)))) { if (_wcsicmp(L"install", argv[1] + 1) == 0) { SvcInstall(); } else if (_wcsicmp(L"remove", argv[1] + 1) == 0) { SvcUninstall(); } else if (_wcsicmp(L"query", argv[1] + 1) == 0) { SvcQueryConfig(); } else if(_wcsicmp(L"start",argv[1] + 1) == 0) { SvcStart(); } else if(_wcsicmp(L"stop",argv[1] + 1) == 0) { SvcStopNow(); } } else { _putws(L"Parameters:"); _putws(L" -install to install the service (require admin permission)"); _putws(L" -remove to remove the service (require admin permission)"); _putws(L" -query to query the configuration of the service"); _putws(L" -start to start the service"); _putws(L" -stop to stop the service"); RunService(); } return 0; }
代码中已经写的很清楚了,我的项目名称为Win8Service,只要运行Win8Service.exe -install,服务就会被安装。
注意:cmd必须要用admin启动。win8下做法:WIN+Q键,打开Search panel,输入cmd,右击Command Prompt,选择Run as administrator。
下面看看这几个函数的实现:
Service.h

下面看看运行结果如何。
WIN+R,调出RUN,输入services.msc调出Service管理。在这里你就会看见CppWin8Service Demo,点击一下,会发现其没有运行。
我们在刚刚install的控制台继续运行:
D:\honeywell\workspace\Win8Service\Debug>Win8Service.exe -install CppWin8Service Demo installed. D:\honeywell\workspace\Win8Service\Debug>Win8Service.exe -start CppWin8Service Demo started.
刷新一下Service,会看到此服务以及启动。
打开事件查看器(运行eventvwr.msc),Windows logs---》Application中可以看到CppWin8Service的infomation,比如:
CppWin8Service Enter SvcInit
二、外部程序启动和停止此服务
服务跑起来了,那么我们如何在外部程序中控制它呢?其实很简单,就是用上面的SvcStart和SvcStopNow方法来做就可以了。
我们新建一个MFC对话框程序,加两个button,一个启动一个停止。将两个函数拷进去,然后包含一下此头文件就可以了。
#include <winsvc.h>
三、批处理安装服务程序
说白了,就是用sc命令来安装启动服务程序,用批处理来包装一下,注意运行批处理时也要用admin。
sc命令见sc命令创建启动服务。
Service安装和启动的bat:
@echo. start service! @echo off @sc create LincTestServer binPath= "D:\XXX\Debug\NewService.exe" @sc start LincTestServer @sc config LincTestServer start= AUTO @sc config LincTestServer displayname="linc service" @echo off @echo. start ok! @pause
停止的bat:
@echo.stop service @echo off @sc stop LincTestServer @echo off @echo.service stoped @pause
卸载的bat:
@echo.delete service @echo off @sc delete LincTestServer @echo off @echo.service deleted @pause
