NetUserGetInfo - API Call

Question:
I am using "NetUserGetInfo" API call to get the NT user profile. I use:
typedef struct _USER_INFO_3
How can I parse the "usri3_flags" member in detail?

Answer:
Use this:

Option Explicit

Private Const UserInfo1 As Long = 1&

Private Type USER_INFO_1
   usri1_name              As Long
   usri1_password          As Long
   usri1_password_age      As Long
   usri1_priv              As Long
   usri1_home_dir          As Long
   usri1_comment           As Long
   usri1_flags             As Long
   usri1_script_path       As Long
End Type
    
Public Declare Sub CopyMem Lib "kernel32" Alias "RtlMoveMemory" _
   (pTo As Any, pFrom As Any, ByVal lCount As Long)
Private Declare Function NetApiBufferFree Lib "netapi32.dll" _
   (ByVal lngPtrBuffer As Long) As Long
Private Declare Function NetUserGetInfo Lib "netapi32" _
   (ByVal psServer As Long, ByVal psUser As Long, ByVal lLevel As Long, _
   lngPtrBuffer As Long) As Long

Private Const NERR_Success             As Long = 0&

Private Const UF_ACCOUNTDISABLE        As Long = &H2
Private Const UF_SCRIPT                As Long = &H1&
Private Const UF_HOMEDIR_REQUIRED      As Long = &H8&
Private Const UF_LOCKOUT               As Long = &H10&
Private Const UF_PASSWD_NOTREQD        As Long = &H20&
Private Const UF_PASSWD_CANT_CHANGE    As Long = &H40&
Private Const UF_NORMAL_ACCOUNT        As Long = &H200&
Private Const UF_SERVER_TRUST_ACCOUNT  As Long = &H2000&
Private Const UF_DONT_EXPIRE_PASSWD    As Long = &H10000
Private Const UF_MNS_LOGON_ACCOUNT     As Long = &H20000
Private Const UF_TEMP_DUPLICATE_ACCOUNT      As Long = &H100&
Private Const UF_INTERDOMAIN_TRUST_ACCOUNT   As Long = &H800&
Private Const UF_WORKSTATION_TRUST_ACCOUNT   As Long = &H1000&
