I have observed that when you hide the Horizontal Scrollbar, it will not scroll when using the
sbxStudyBtnHolder.Perform(WM_HSCROLL, SB_LINEDOWN, 0);
how can we make it possible?
You can still scroll it using ScrollBy
:
ScrollBox1.ScrollBy(-8, 0);
or
ScrollBox1.ScrollBy(-ScrollBox1.HorzScrollBar.Increment, 0);
