Re: Scrolling Control Container
Tech-Archive recommends: Fix windows errors by optimizing your registry
Yes I tried the HScroll and VScroll properties of the panel and they
appeared to have no effect at all. As soon as controls were added that went
outside the visible boundaries the scroll bars returned. The only effective
way I found to get rid of them for good so I could do the scrolling myself,
was the override of the WndProc.
