WM_MOVE Overview  Group

The WM_MOVE message is sent after a window has been moved.

WM_MOVE 

xPos = (int)(short) LOWORD(lParam);    // horizontal position 

yPos = (int)(short) HIWORD(lParam);    // vertical position 

 

Parameters

xPos

Value of the low-order word of lParam. Specifies the x-coordinate of the upper-left corner of the client area of the window.

yPos

Value of the high-order word of lParam. Specifies the y-coordinate of the upper-left corner of the client area of the window.

Return Values

If an application processes this message, it should return zero.

Remarks

The xPos and yPos parameters are given in screen coordinates for overlapped and pop-up windows and in parent-client coordinates for child windows.

An application can use the MAKEPOINTS macro to convert the lParam parameter to a POINTS structure.
