The LVM_SETITEMPOSITION32 message moves an item to a specified position in a list view control, which must be in icon or small icon view. This message differs from the LVM_SETITEMPOSITION message in that it uses 32-bit coordinates. You can send this message explicitly or by using the ListView_SetItemPosition32 macro.
LVM_SETITEMPOSITION32 wParam = (WPARAM) (int) iItem; lParam = (LPARAM) (LPPOINT) lpptNewPos;
No return value.
If you send this message by using the ListView_SetItemPosition32 macro, it has no return value.
