Header file: Winuser.h
Windows CE versions: 1.0 and later

Syntax

BOOL IsWindowVisible(HWND hWnd);

Parameters

hWnd

Handle to the window to test.

Return Values

Nonzero indicates that the specified window and its parent window have the WS_VISIBLE style. Zero indicates that the specified window and its parent window do not have the WS_VISIBLE style. Because the return value specifies whether the window has the WS_VISIBLE style, it may be nonzero even if the window is totally obscured by other windows.

Remarks

The visibility state of a window is indicated by the WS_VISIBLE style bit. When WS_VISIBLE is set, the window is displayed and subsequent drawing into it is displayed as long as the window has the WS_VISIBLE style.

Any drawing to a window with the WS_VISIBLE style will not be displayed if the window is obscured by other windows or is clipped by its parent window.
