[RESOLVED] Why this code don't chage size of control?

Code:

---

        case WM_SIZE:
        SendMessage(hsb, WM_SIZE, 0, 0);
                {RECT WindowRect;
        GetWindowRect(hwnd, &WindowRect);
                int width = WindowRect.right-WindowRect.left;
                SetWindowPos(hProgress, HWND_NOTOPMOST, 20, 150, width-20, 17, 0);
                break;}

---

Progress bar saves previous state.
