WM_WINDOWPOSCHANGED

Windows Embedded CE 6.0 R3

4/8/2010

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 SetWindowPos function or another window-management function.

Syntax

WM_WINDOWPOSCHANGED lpwp = (LPWINDOWPOS) lParam;

Parameters

  • lpwp
    Long pointer to a WINDOWPOS structure 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 DefWindowProc function 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
