Dear Colleagues,

Do you know a way to determine if the group to the which the user belongs
(administrator, guest, standard user, ...)?

I tried using Environ but could not find a solution this way.

Thanks for your help,

MrT

Randy Birch has a VB solution for the current user which you could modify.
It is at vbnet.mvps.ortg, search on How to Determine if the Current User is
a Member of Administrator

I've been playing a bit.. and I hope you have NT/XP machines :)


This will tell you if he has admin rights on the current
machine (optionally you may enter a server name)

Officially it should go into a data structure
of type User_info_1 but i've tried to make it
the code as simple as possble and used an array
of longs instead.


Enumerating the Usergroups was getting a bit more complex..


Option Explicit

'ADVAPI32
Private Declare Function GetUserName Lib "advapi32.dll" _
Alias "GetUserNameA" (ByVal lpBuffer As String, _
nSize As Long) As Long

Private Declare Function NetUserGetInfo Lib "netapi32" ( _
ByVal ServerName As Long, ByVal UserName As Long, _
ByVal Level As Long, ByRef ptrBuffer As Long) As Long

Private Declare Function NetApiBufferFree Lib "netapi32" ( _
ByVal ptrBuffer As Long) As Long

'KERNEL32
Private Declare Sub CopyMemory Lib "kernel32" Alias _
"RtlMoveMemory" (Destination As Any, Source As Any, _
ByVal Length As Long)


Function IsAdmin() as Boolean
Dim lLen&, lpBuf&, aUI1&(0 To 7)
Dim sUser$, sServer$

If Not Application.OperatingSystem Like "*32* NT *" Then
IsAdmin = True 'win95/98/Me cant limit userrights
Exit Function
End If

lLen = 255
sUser = Space(lLen)
If GetUserName(sUser, lLen) Then
'optional: type servername...
sServer = vbNullString & vbNullChar

If (NetUserGetInfo(StrPtr(sServer), StrPtr(sUser), 1, lpBuf) = 0&)
Then
Call CopyMemory(aUI1(0), ByVal lpBuf, 32)
Call NetApiBufferFree(ByVal lpBuf)
IsAdmin = (aUI1(3) = 2)
End If
End If

End Function

I've just had a look at Randy Birch's solution
on VBnet as mentioned by Bob.
http://vbnet.mvps.org/code/network/isadministrator.htm

I'm wondering if my simple code achieves the same results :)

Let me know please!

Thanks a lot for these inputs. I've modified KeepITcool's code so that it
completely matches my needs + used the Environ function to avoid using the
GetUserName API function (is that really efficient?). I copied the code below.

I only tried it on an XP machine. It still needs to be tested on other
systems including NT 4.0. If anyone can do it, that would allow to have a
nice and consise piece of code, thanks to KeepItCool.

Tk,

Environ for username IS faster.
Added Environ OS for NT testing
Added conditional compile for Win32 (vs Mac and Win16)

Further condensing it.. <g

Public Function UserType() As Byte
'returns 0 if admin, 1 if user, 2 if guest
' 255 for errors
'Author : keepITcool Excel.Programming
'
UserType = 255
#If Win32 Then
'only run on 32bit Windows
Dim lpBuf&, sUser$, lPriv&
If Environ$("OS") < vbNullString Then
'OS env variable only found on NT/2k/XP machines
sUser = Environ$("Username") & vbNullChar
If NetUserGetInfo(0, StrPtr(sUser), 1, lpBuf) = 0 Then
Call CopyMemory(lPriv, ByVal lpBuf + 12, 4)
Call NetApiBufferFree(lpBuf)
UserType = 2 - lPriv
End If
Else
'win95/98/Me cant limit userrights
UserType = 0
End If
#End If
End Function

Hi MrT;
You can try:
Sub WhichGroup()
With CreateObject("Wscript.Network")
GetUserGroup .UserDomain, .UserName
End With
End Sub

Sub GetUserGroup(strDomain, strUser)
Dim Group As Object, User As Object
Set User = GetObject("WinNT://" & strDomain & "/" & strUser & ",user")
For Each Group In User.Groups
MsgBox Group.Name
Next
Set Group = Nothing: Set User = Nothing
End Sub

Congrats Michel ... even more concise. But I have a time constraint and your
solution is much slower than the solution of KeepItcool (with my contribution
for a few milliseconds ;-)), because of the call to
GetObject("WinNT://" & strDomain & "/" & strUser & ",user")

As it seems you are a wizard, may be you can find a faster solution?

Yeah, use early binding. Go to Project | References and put a check next to
Windows Script Host Object Model If it is not there, browse for the file
wshom.ocx (c:\windows\system32 on my machine)) and open it.

Then change the code to

Sub WhichGroup()
Dim WSHNet As WshNetwork

Set WSHNet = New WshNetwork
With WSHNet
GetUserGroup .UserDomain, .UserName
End With
End Sub

Sub GetUserGroup(strDomain, strUser)
Dim Group As Object, User As Object
Set User = GetObject("WinNT://" & strDomain & "/" & strUser & ",user")
For Each Group In User.Groups
MsgBox Group.Name
Next
Set Group = Nothing: Set User = Nothing
End Sub

Hi MrT;
In complement of the message of Bob, go to Project | References and put a
check next to Active DS Type Library. If it is not there, browse for the
file (c:\windows\system32\activeds.tlb) and open it.

Then change the code to
Sub WhichGroup()
Dim WSHNet As WshNetwork
Set WSHNet = New WshNetwork
With WSHNet
MsgBox IsAdmin(.UserDomain, .UserName)
End With
End Sub

Private Function IsAdmin(strDomain, strUser) As Boolean
Dim Group As IADsGroup, User As IADsUser
Set User = GetObject("WinNT://" & strDomain & "/" & strUser & ",user")
Set Group = GetObject("WinNT://" & strDomain & "/Administrators, group")
IsAdmin = Group.IsMember(User.ADsPath)
End Function
