Pointer to an APPBARDATA structure. You must specify the cbSize member when sending this message; all other members are ignored.

Return code Description
ABS_ALWAYSONTOP
 The taskbar is in the always-on-top state.
Note: As of Windows 7, ABS_ALWAYSONTOP is no longer returned because the taskbar is always in that state. Older code should be updated to ignore the absence of this value in not assume that return value to mean that the taskbar is not in the always-on-top state.
ABS_AUTOHIDE
 The taskbar is in the autohide state.
