Unlike the Windows 95 common controls, the standard list box doesn’t have a horizontal scrollbar when list items are too wide to fit within the list box. Fortunately, it’s not hard to direct a list-box control to display a horizontal scrollbar.
Add this code to a form’s Load event. It fills a list box with 100 long strings and calls SetHScroll to show a horizontal scrollbar in the list box:

 Private Sub Form_Load()	Dim i As Integer	For i = 1 To 100		List1.AddItem CStr(i) & _			" bottle(s) of beer on the wall."	Next i	SetHScroll Me, List1, List1.List(0)End Sub

Add this code, which includes the required API declarations and the SetHScroll routine, to a BAS module. The SetHScroll routine uses the SendMessage API function to send the LB_SETHORIZONTALEXTENT message to a list box. The last argument is an item from the list, preferably one of the longest items. SetHScroll determines the string’s width in pixels and passes this value to the list box along with the LB_SETHORIZONTALEXTENT message. The list box sets its horizontal extent to this value, and if it is wider than the list-box control, the list box displays a horizontal scrollbar:
