Reducing flickering when resizing

[Kibble]

I am looking for ways to reduce flickering when resizing. I've set WS_CLIPCHILDREN on parent windows, which reduced a lot of flicker. I couldn't find anywhere were WS_CLIPSIBLINGS made a difference. I still have a lot of flicker, and its only really in 3 places. In my edit controls, tab controls, and list controls, there is a lot of flickering when resizing. How do I stop this from happening?

edit: I've also tried to put FALSE in the last parameter of MoveWindow, that doesn't help and causes really bad smearing effects. also tried making window classes without CS_VREDRAW and CS_HREDRAW in PreCreateWindow, usually caused bad smearing effects also.
