Default Array again limit

Thanks Helmut, will have to do some research on LDAP as I'm not really too
familiar with it either.

It's definitely not a problem with the array.
I usually program in VB6 and was uncertain where the limit would
be in Excel VBA, so I tested it on my system with Excel2000:
ReDim arrNames(10000000) still worked,
ReDim arrNames(100000000) caused an "Out of memory" error.
I then filled an array of one million elements with strings, always
redimming it like in your code. No problem at all.

It's a problem with your LDAP query. I never used LDAP so
I can't help you with this.

BTW, assuming you get it fixed, change your other code to make
it faster:
- Dim arrNames() as String
- initially ReDim arrNames(5000)
- when done with the loop: ReDim Preserve arrNames(intSize-1)
Continually redimming the array slows down your code dramatically.
You use a slow sorting method, use Quicksort instead.
For counters like intSize, j and i use Longs instead of Variants.

HTH.

the range SESCREEN is simply a named range on a spreadsheet, plenty or
room for 4000 names.

The problem seems to be I never return more or lass than 1500 names. I
can add a watch to objGroup.Member and it has
1499, from 0-1499 so 1500 members. so thie issue seems to be a limit on
either the array can't hold more than 1500, or the LDAP query can't
return more than 1500.

Where - and how - do you define the range "SESCREEN"
I tested the Transpose function to see where its limitations are.
It will happily fill a given range without complaining that the provided
array contains more values than the range could hold.

So I asked if you really checked how many names your code retrieved
in the for each loop and stored in the array arrNames.

well as soon as the objuser.CN gets, it is 1499

Just for clarity:
Is intSize = 1499 at the end of the For-Each-Loop?

using the following to get Active Directory group membership, is it
possible that once I return a value say "Bob Smith" that is NOT
unique this will stop. I return 1499 members names no matter how many
people are in the group. I've added people to the group to be sure,
I still get 1499 as a result.

I am NOT returning a domain ID which would be unique, so perhaps
that's an issue.



Sub ADGroupMembers()
Dim arrNames()
intSize = 0

'Let's clear the range first
Range("SESCREEN").ClearContents

'Get the AD Group Info for BATY-SESCREEN
Set objGroup = GetObject("LDAP://CN= BATY-SESCREEN,OU=Security
Groups,DC=baty,DC=com")

'Getting User Names and increase the array size
For Each strUser In objGroup.Member
Set objuser = GetObject("LDAP://" & strUser)
ReDim Preserve arrNames(intSize)
arrNames(intSize) = objuser.CN
intSize = intSize + 1
Next

'In order to sort, we have to convert to Uppercase.
For i = (UBound(arrNames) - 1) To 0 Step -1
For j = 0 To i
If UCase(arrNames(j)) UCase(arrNames(j + 1)) Then
strHolder = arrNames(j + 1)
arrNames(j + 1) = arrNames(j)
arrNames(j) = strHolder
End If
Next
Next

'Fill the SESCREEN range with the array values
Range("SESCREEN").Value = WorksheetFunction.Transpose(arrNames)

End Sub
