This message is sent to a window whose size, position, or place in the z-order has changed as a result of a call to the SetWindowPosfunction or another window-management function.

Syntax

WM_WINDOWPOSCHANGED 
lpwp = (LPWINDOWPOS) 
lParam;

Parameters

lpwp

Long pointer to a WINDOWPOSstructure that contains information about the window's new size and position.

Return Value

An application should return zero if it processes this message.

Default Action

The DefWindowProcfunction sends the WM_SIZE and WM_MOVE messages to the window.

Remarks

The WM_SIZE and WM_MOVE messages are not sent if an application handles the WM_WINDOWPOSCHANGED message without calling DefWindowProc. It is more efficient to perform any move or size change processing during the WM_WINDOWPOSCHANGED message without calling DefWindowProc.

Requirements

Header winuser.h
Windows Embedded CE Windows CE 1.0 and later
Windows Mobile Windows Mobile Version 5.0 and later
