VBS Script for modifying multi-value Active Directory display specifier - vbscript

Question

Following the howto Extending the Active Directory Schema To Track Custom Info I'm able to setup a single-value schema attribute that is easily changeable via a context menu in ADUC. Multi-value schema attributes get considerably more complicated. Say (for the sake of argument) my value is "Projects" and each user may be a list as many projects as necessary.
Following is a sad little script that will set Project to a single value:
Dim oproject
Dim oUser1
Dim temp1
Set oproject = Wscript.Arguments
Set oUser1 = GetObject(oproject(0))
temp1 = InputBox("Project: " & oUser1.project & vbCRLF & vbCRLF & "Project")
if temp1 <> "" then oUser1.Put "project",temp1
oUser1.SetInfo
Set oUser1 = Nothing
Set oproject = Nothing
Set temp1 = Nothing
WScript.Quit
How can I modify this to allow, assign, and modify multiple values?

Answer 1

I gave up on an elegant UI and just went with the semicolon delimited list. Here's the code if anyone cares:
Dim objProject
Dim objUser
Dim temp1, title, message, default
Dim projects
title = "Projects"
Set objProject = Wscript.Arguments
Set objUser = GetObject(objProject(0))
'Find our current projects
projects = objUser.projects
If Not isArray(projects) Then
projects = Array(projects)
End If
'Setup our message box
message = "Semicolon-delimited list of Projects"
default = arrayToStr(projects)
temp1 = InputBox(message, title, default)
'catch cancels
if IsEmpty(temp1) Then
WScript.Quit
End If
' update our data
projects = strToArray(temp1)
objUser.Put "projects",projects
objUser.SetInfo
'Clean up and quit
Set projects = Nothing
Set objUser = Nothing
Set objProject = Nothing
Set temp1 = Nothing
Set title = Nothing
Set message = Nothing
Set default = Nothing
WScript.Quit
'Functions
Function strToArray(s)
Dim a
Dim token
' discard blank entries
For Each token in split(s, ";")
token = trim(token)
If token <> "" Then
If isEmpty(a) Then
a = token
Else
a = a & ";" & token
End If
End If
Next
' return array
strToArray = split(a, ";")
End Function
Function arrayToStr(a)
Dim s
Dim token
For Each token in a
If isEmpty(s) Then
s = token
Else
s = s & ";" & token
End If
Next
' return string
arrayToStr = s
End Function
