A "Scripting.Dictionary" object is much better suited to this task since it has the Exists() method to check whether an entry is already in there. If you're intent on using arrays you'll have to write some code yourself to check whether the value is already in the array.

i tried the dictionary but it is giving me an error and i dont know how to solve it cos i dont know how to deal with dictionaries..

what i want is to keep adding and ItemID to a dictionary,
everytime i add a new Id i check wther it exists or not. if yes then i dont add,,

then i need a way of retrieving the ids of the object i am storing the ids in

Is there an eas way?

OK, maybe an example would help.

Code:

Dim ID
Dim dct
Set dct = Server.CreateObject("Scripting.Dictionary")

' you don't say where the IDs come from, so I'll use a recordset (rs) for this example
' Here we add all unique IDs into the Dictionary
Do While Not rs.EOF
    ID = rs.Fields("ID").Value
    If Not dct.Exists(ID) Then

        ' I don't know whether you want to associate anything with the IDs 
        ' so I'm just using Null here
        dct.Add ID, Null 

    End If

    rs.MoveNext
Loop

' all the unique IDs are now in the Dictionary
' to get an array of the IDs use:
someArray = dct.Keys

' to get an array of the items associated with the IDs (Nulls in this case) use:
someArray = dct.Items

' to get the item associated with a particular ID use:
someItem = dct(anyID)

hth, if not then explain a bit more what you're trying to achieve and post some of your code.
