VS2019C++创建windows服务代码
在vs2019创建C++桌面应用程序，然后主程序用以下代码覆盖就可以了。具体步骤：
1）新建项目，选择C++windows平台的”windows桌面应用程序“；
2）用以下代码覆盖生成的代码；
3）打开cmd，创建服务： sc create ServerNameTest binpath= "C:\Users\Administrator\source\repos\WindowsProject1\Debug\WindowsProject1.exe"；
4）编译好后，打开任务管理器中服务，找到ServerNameTest，手动打开，服务就可以运行了。也可以正常停止服务。
