Flags to be passed to SetWindowPos, or zero if SetWindowPos should not be called. The default is zero. See the Remarks section for a list of preset flags.
Nonzero if style was successfully modified; otherwise, 0.

If nFlags is nonzero, ModifyStyleEx calls the Windows API function SetWindowPos and redraws the window by combining nFlags with the following four preset flags:
SWP_NOSIZE Retains the current size.
SWP_NOMOVE Retains the current position.
SWP_NOZORDER Retains the current Z order.
SWP_NOACTIVATE Does not activate the window.
To modify windows using regular window styles, see ModifyStyle.
