WM_CONTROLPOINTER
id = (USHORT) SHORT1FROMMP(mp1);      /* sender ID               */
hptr = (HPOINTER) LONGFROMMP(mp2);    /* handle to mouse pointer */
 
The WM_CONTROLPOINTER message is sent to a control's owner when the mouse
pointer moves over the control window, allowing the owner to set the mouse
pointer to a different shape. The control passes an HPOINTER handle to a
mouse pointer as part of this message. An application can alter the default
pointer shape by passing back a different HPOINTER handle as the result of
this message.

Return Value

mouse pointer to be used while the mouse is positioned over the control
window.
