I haven't tested it, but it may work

VB Code:
  1. Private Declare Function ShowScrollBar Lib "user32" Alias "ShowScrollBar" (ByVal hwnd As Long, ByVal wBar As Long, ByVal bShow As Long) As Long
  2. Private Const SB_BOTH = 3
  3. Private Const SB_HORZ = 0
  4. Private Const SB_VERT = 1
  5. ShowScrollBar Combo1.hwnd, SB_BOTH, 1
