Can anyone tell me how to prevent the rebar and listview blinking when I try to size the window? I use SetWindowPos to size them. Here is my piece of code:

        .ELSEIF (uMsg == WM_SIZE)

            movzx eax, WORD PTR 
            INVOKE SetWindowPos, hReBar, NULL, 0, 0, eax, 0, SWP_NOZORDER

            INVOKE SendMessage, hStatusBar, WM_SIZE, wParam, lParam

            INVOKE GetWindowRect, hStatusBar, ADDR rc
            movzx esi, WORD PTR 
            sub esi, rc.bottom
            add esi, rc.top
            INVOKE GetWindowRect, hReBar, ADDR rc
            mov eax, rc.bottom
            sub eax, rc.top
            add eax, 2
            sub esi, eax
            movzx ecx, WORD PTR 
            INVOKE SetWindowPos, hListView, NULL, 0, eax, ecx, esi, SWP_NOZORDER

RVA: I've coded almost the same as you, a rebar and status bar, but with a MDI window, and tried several ways to reduce flicker. What really helped me is setting the WS_CLIPSIBLINGS style for every window and also the WS_CLIPCHILDREN style for windows with children. This almost eliminated flicker for me, except for the toolbar on my rebar. You can solve this by resizing the rebar horizontally much larger than the actual parent window, and then never resize it in WM_SIZE. Thomas
