Listbox Horizontal Scroll

How do you add a horizontal scroll bar to a list box ?
I have only one column but the text lenght for each row is actually longer the listbox width I defined. I could not found a horizontal scroll bar function.

Vertical Scroll bar appears when the row gets bigger than the lenght of the listbox, but I cannot do that for horizontal ??

Thanks

Edith

Const LB_SETHORIZONTALEXTENT = &H194
Declare Function SendMessage Lib "user32" Alias "SendMessageA" _
     (ByVal hwnd As Long, ByVal wMsg As Long, ByVal wParam As Long, _
     lParam As Any) As Long

Dim x As Long
x = SendMessage(list1.hWnd, LB_SETHORIZONTALEXTENT, list1.Width * 2, _
     ByVal 0&)

Note: the `list1.Width*2' parameter specifies the scrollable width of the
listbox in pixels. You may need to adjust the form's ScaleMode or
otherwise experiment to find the best value.

Here is also a function for automatic adjustment. Call this function whenever the listbox is changed.

Declare Function SendMessage Lib "user32" Alias
"SendMessageA" (ByVal hWnd As Long, ByVal wMsg As Long,
ByVal wParam As Long, lParam As Long) As Long

Const WM_USER = &H400
Const LB_SETHORIZONTALEXTENT = WM_USER + 21

Sub CheckListBox
    Dim i%, res&
    Dim Scrollwidth&
   
    For i% = 0 To Form1.List1.ListCount
       If Form1.TextWidth(Form1.List1.List(i%)) > Scrollwidth& Then _
        Scrollwidth& = Form1.TextWidth(Form1.List1.List(i%))
    Next i%

    res& = SendMessage(Form1.List1.hWnd, LB_SETHORIZONTALEXTENT, _
        Scrollwidth&, 0&)
End Sub
