Hello

Try to define a font of Canvas before calling TextWidth (I mean DestListBox.Canvas.Font.Assign(DestListBox.Font)).
This horizontal scrollbar was tested already and was working well..

you are right.. in a fresh project it is working with this.. but in my big project it is not working.

Thank you for demo.
This solution (LB_SETHORIZONTALEXTENT message) working if listbox is visible already seems.
Try to call AddHScroll after UpdateFrame…
