I can give a control scrollbars by this API , but how can I give them code , I mean how can I make them scroll something???????

VB Code:
  1. Private Declare Function ShowScrollBar Lib "user32" (ByVal hwnd As Long, ByVal wBar As Long, ByVal bShow As Long) As Long
  2. Private Const SB_HORZ = 0
  3. Private Const SB_VERT = 1
  4. Private Const SB_BOTH = 3
  5. Private Sub Form_Load()
  6.     ShowScrollBar Text1.hwnd, SB_BOTH, True
  7. End Sub
