Here's a quick attempt at some VB6 code.

Dim Found as Boolean
For I = list1.listcount - 1 To 0 Step -1
  Found = False
  For J = 0 to list2.listcount - 1
    If list2.list(J) = list1.list(I) Then
      Found = True
      Exit For
    End If
  Next
  If Not Found Then
    List1.RemoveItem I
  End If
Next
 

That should be enough to get you started, anyway - it's just straight off the top of my head, so may need debugging.

And if you're using Vb.Net then my syntax may be all wrong, but the logic should still apply. If you're using VBA in Access or something, then all bets are off.
