Answer 1

Windows supports a re-size batching operation that is meant to avoid flicker caused when lots of child windows are indepently resized. See BeginDeferWindowPos for more information on that.

If that is not working, then try the WM_SETREDRAW message. It looks possible to stop drawing of the parent window - which will inhibit all the child controls, then, when the layout is finished, enable drawing again, and call RedrawWindow to repaint the entire window in one pass. I did rather think that this is what Defered window positioning would use internally.
