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

#pragma once

// Internal name of the service
#define SERVICE_NAME             L"CppWin8Service"

// Displayed name of the service
#define SERVICE_DISPLAY_NAME     L"CppWin8Service Demo"

// List of service dependencies - "dep1\0dep2\0\0"
#define SERVICE_DEPENDENCIES     L""

// The name of the account under which the service should run
#define SERVICE_ACCOUNT          L"NT AUTHORITY\\LocalService"

// The password to the service account name
#define SERVICE_PASSWORD         NULL

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
