removing duplicate items in list

hi all,

I have a list box with a few 1000s items in it.. there are many duplicate items in it.. some several times actaully.

how can I remove all duplicates from the list.

thanks a lot guys!

I'd suggest passing all the elements into an array, use some sort of bubble sort to put only unique items into another array and finally, after deleting all elements in the combo box, populate the combo box with the entries from the second array

How is this data being loaded to the listbox?

thanks guys

it will be populated via database..

however.. at the moment I just put a bunch of "list1.additem XXXX" in the load form event as a demo...

any advise?

cheers

A simple little loop should do the trick nicely. :)

VB Code:

Private Sub Command1_Click()
Dim i As Long
Dim j As Long
    With List1
        For i = 0 To .ListCount - 1
            For j = .ListCount To (i + 1) Step -1
                If .List(j) = .List(i) Then
                    .RemoveItem j
                End If
            Next
        Next
    End With
 
End Sub

cant you just filter out the duplicates when you query the db?

Couldn't you load as DISTNCT?

Thanks a lot!!!

damn why did I not think of that!

my brain gets dizzy when I get into nested loops....
