Advanced data structures

Are there advanced data structures in vb6 (like maps and vectors in c++) ?

thx.

Welcome to the forums. :wave:

Not in the same sense that you might be used to. What are you looking to accomplish?

thx man.

For a given string (key) i want to map an integer (value)

I'm not sure if this is quite what you are looking for but a Collection might do...

Code:

---

Option Explicit
Dim MyCollection As Collection

Private Sub Form_Load()
  Set MyCollection = New Collection
  With MyCollection
    .Add CInt(123), "Tom"
    .Add CInt(456), "Dick"
    .Add CInt(789), "Harry"
  End With
End Sub

Private Sub Command2_Click()
  With MyCollection
    .Remove "Harry"
    .Add CInt(666), "Harry"
  End With
End Sub

Private Sub Command1_Click()
  With MyCollection
    Debug.Print .Item("Tom")
    Debug.Print .Item("Dick")
    Debug.Print .Item("Harry")
  End With
End Sub

Private Sub Form_Unload(Cancel As Integer)
  Set MyCollection = Nothing
End Sub

You can also link numbers as keys, but you must force them to Strings:

Code:

---

MyCollection.Add "Harry", CStr(666)

VB is unable to coerce values and other data to collection keys, so it must be done explicitly.
