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.

WM_WINDOWPOSCHANGED
lpwp= 
(LPWINDOWPOS)
lParam;

Parameters

lpwp

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

Return Values

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.
