ACC2: Only Admins Group Members Can List Groups They Belong To (124240)
The information in this article applies to:
This article was previously published under Q124240 SYMPTOMS
Advanced: Requires expert coding, interoperability, and multiuser skills.
You can use Access Basic code to determine to which groups a user belongs,
but only members of the Admins group can view this information. For
example, running the following sample function will return the current
user's name and a list of the groups to which the current user belongs:
Function GetGroups ()
Dim W As WorkSpace, US As String, U As User, i As Integer, j As Integer
Set W = DBEngine.Workspaces(0)
US = CurrentUser()
Set U = W.Users(US)
Debug.Print U.Name
For j = 0 To U.Groups.Count - 1
Debug.Print " " & U(j).Name
Next
End Function
If the current user is not a member of the Admins group, the following
error message will be generated:
Record(s) can't be read; no Read Data permissions on 'MSysGroups'
RESOLUTION
To work around this behavior, you must log in to a new workspace as a
member of the Admins group and pass the name of the user whose groups you
want to list. The following sample function demonstrates this method:
Function GetGroups2 ()
Dim W As WorkSpace, US As String, U As User, i As Integer
Set W = DBEngine.CreateWorkspace("NewWS", "MyAdmin", "MyPassword")
US = CurrentUser()
Set U = W.users(US)
Debug.Print U.Name
For i = 0 To U.Groups.Count - 1
Debug.Print " " & U(i).Name
Next
End Function
NOTE: This function assumes the existence of a user named MyAdmin who is a
member of the Admins group in the current system database with an account
password of MyPassword.
STATUS
This behavior no longer occurs in Microsoft Access version 7.0.
