windows服务和桌面交互（转载）

windows 服务默认位于windows 7 的session 0 中，桌面程序位于session 1中，默认情况下二者无法交互

使用如下方法可以使在服务安装完成之后默认勾选“属性”->“登录”->“允许服务与桌面交互。

        private void serviceInstaller1_AfterInstall(object sender, InstallEventArgs e)
        {

            SetServiceDesktopInsteract("你的服务名称");
            System.ServiceProcess.ServiceController sc = new System.ServiceProcess.ServiceController();
            sc.ServiceName = "你的服务名称";
            sc.Start();
        }

        private void SetServiceDesktopInsteract(string serviceName)
        {
            System.Management.ManagementObject wmiService = new System.Management.ManagementObject(string.Format("Win32_Service.Name='{0}'", serviceName));
            System.Management.ManagementBaseObject changeMethod = wmiService.GetMethodParameters("Change");
            changeMethod["DesktopInteract"] = true;
            System.Management.ManagementBaseObject OutParam = wmiService.InvokeMethod("Change", changeMethod, null);
        }
