<h3>一.Service</h3>
<p>借助MSDN上<a href="http://code.msdn.microsoft.com/CppWin7TriggerStartService-8ba5bd5b/sourcecode?fileId=64923&pathId=927862711" rel="noopener noreferrer" target="_blank">Win7 Service的Demo</a>和《<a href="http://blog.csdn.net/lincyang/article/details/6231406" rel="noopener noreferrer" target="_blank">用VC++建立Service服务应用程序</a>》，在Win8上经历各种磨难，终于跑起来自己改装的服务程序了。</p>
<p>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。</p>
<p>报错：</p>
<pre class="blockcode"><code class="language-plain">OpenSCManager failed w/err 0x00000005</code></pre>
<p>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。</p>
<p><br> </p>
<p>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。）</p>
<p>main.c只是程序的入口，运行时接受参数。</p>
<pre class="blockcode"><code class="language-cpp">#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;
}</code></pre>
<p>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。</p>
<p><strong>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。</strong></p>

<p>下面看看这几个函数的实现：</p>
<p>Service.h</p>
