If the specified window, its parent window, its parent's parent window, and so forth, have the <b>WS_VISIBLE</b> style, the return value is nonzero. Otherwise, the return value is zero.
If the specified window, its parent window, its parent's parent window, and so forth, have the <b>WS_VISIBLE</b> style, the return value is nonzero. Otherwise, or in the case of an error, the return value is zero.
