CreateService的 第十二个参数怎么用？

  SC_HANDLE CreateService(
  SC_HANDLE hSCManager,       // handle to SCM database
  LPCTSTR lpServiceName,      // name of service to start
  LPCTSTR lpDisplayName,      // display name
  DWORD dwDesiredAccess,      // type of access to service
  DWORD dwServiceType,        // type of service
  DWORD dwStartType,          // when to start service
  DWORD dwErrorControl,       // severity of service failure
  LPCTSTR lpBinaryPathName,   // name of binary file
  LPCTSTR lpLoadOrderGroup,   // name of load ordering group
  LPDWORD lpdwTagId,          // tag identifier
  LPCTSTR lpDependencies,     // array of dependency names
  LPCTSTR lpServiceStartName, // account name
  LPCTSTR lpPassword          // account password
);
看了MSDN。还是不会。
我需要最高权限。不要NULL，
  LPCTSTR lpServiceStartName, // account name
  LPCTSTR lpPassword          // account password
这2个参数该如何设置？谢谢了
给个例子吧。万分感谢

找到了个答案。。明天看看对不对。。。先贴给大家 看看。
_T("jack")
_T("empty")

seem like a good start...

Note that a password of 0 length is a Really Bad Idea and has a number of seriously nasty
security implications...for example, an account logged in with a zero-length password is
denied network access in WinXP.
