VC++信息安全编程（4）创建Windows服务

1、vc+信息安全编程（4）创建windows服务microsoft windows 服务（即，以前的 nt 服务）使您能够创建在它们自己的 windows 会话中可长时光运行的可执行应用程序。这些服务可以在计算机启动时自动启动，可以暂停和重新启动而且不显示任何用户界面。这使服务十分适合在服务器上用法，或任何时候，为了不影响在同一台计算机上工作的其他用户，需要长时光运行功能时用法。还可以在不同于登录取户的特定用户帐户或默认计算机帐户的平安上下文中运行服务。请见代码注释分析windows服务ilude stdafx.h include myservice.h include myservicedlg
