本示例子演示了怎样用代码来实现将一个可执行程序做为一个服务注册到系统中。开发本程序是因为我的防火墙在开机后登录后才能启动，有时我开机后会很长时间不登录，这时机器就不在防火墙的保护下。将防火墙做为系统服务注册后，解决了该问题。本例子可以直接使用或参考代码。-example demonstrates how to use code to achieve an executable registered as a service to the system. The development process is because I firewall after login at boot after launch, sometimes I boot will not logged in a very long time, when the machine is not under the protection of the firewall. Firewall as a system service after registration to solve the problem. This example can be used directly or by reference to code.
