[Gambas-user] I need a hint on how to deleted duplicate items in a array

[nando_f at ...951...]

Another very effective and simple would be:

You have your array with data
You create a new empty array.

Loop through each item in your array with data
If it's not in the new array, then add it.

Destroy the original array.
Keep the new one.
...something like (syntax may not be correct)

Public Function RemoveMultiple(a As String[]) As String[] 

  Dim x as Integer
  Dim z as NEW STRING[]

  For x = 1 to a.count()
    if z.Find(a) = 0 Then z.Add(a[x])
  Next

  Return z

END
