[RESOLVED] Help with ShowScrollBar API

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:

Private Declare Function ShowScrollBar Lib "user32" (ByVal hwnd As Long, ByVal wBar As Long, ByVal bShow As Long) As Long
Private Const SB_HORZ = 0
Private Const SB_VERT = 1
Private Const SB_BOTH = 3
Private Sub Form_Load()
    ShowScrollBar Text1.hwnd, SB_BOTH, True
End Sub

well there are couple of approaches - what exactly are you trying to do

You will have to subclass your textbox and process WM_HSCROLL and WM_VSCROLL messages.

I will try it thanks

Sorry but I still need some help as I couldn't understand that topic at MSDN

Here is an example of how to do it for the vertical scrollbar and a picturebox

You'll have to add code for the horizontal.

You'll also have to add code to move the picture once the scrollbar position has been changed

Thank you for help , but plz can anybody send me links for subclassing tutorial
