使用WMI来设置服务（Windows Service）的运行帐号

Windows Service运行的账号类型有两种：

1） 本地系统帐号（Local System Account）;

     使用此帐号，Windows Service即使用当前登录的系统帐号来运行服务。使用此类型帐号，可通过打开Allow service to interact with desktop选项来允许服务与桌面交互；譬如从服务向一个窗口发送消息。

2) 其它帐号；

     使用此类型帐号运行服务与1) 本地系统帐号的一个显著区别是，它不能与桌面交互。

使用WMI来设置服务帐号：

1） 向工程中添加对System.Management.dll的引用；

2） 使用Win32_BaseService的Change方法来设定帐号：

Using service As ManagementObject = New ManagementObject(New ManagementPath(objPath))

Dim wmiParams() As Object = Array.CreateInstance(GetType(Object), 11)

If Not String.IsNullOrEmpty(PrintProvider.Instance.PrintSettings.PrintServiceSetting.Credentials.UserName) Then

If Not PrintProvider.Instance.PrintSettings.PrintServiceSetting.Credentials.UserName.Contains("\") Then

wmiParams(6) = ".\" & PrintProvider.Instance.PrintSettings.PrintServiceSetting.Credentials.UserName

Else

wmiParams(6) = PrintProvider.Instance.PrintSettings.PrintServiceSetting.Credentials.UserName

End If

Else

wmiParams(6) = "LocalSystem"

End If

wmiParams(7) = PrintProvider.Instance.PrintSettings.PrintServiceSetting.Credentials.Password

objResult = service.InvokeMethod("Change", wmiParams)

End Using
