Buenas tardes Comunidad de expertos, estoy tratando de sincronizar el movimiento y zoom en dos ventanas de AutoCAD, es decir, en dos planos abiertos .dwg divididos en dos ventanas una activa y otra inactiva sincronizar el zoom o el movimiento (PAN) de la ventana activa a la inactiva, estuve investigando y encontré este código que hace lo que quiero, el problema es que no logro hacerlo funcionar en VS2019 c++, me da error en las lineas con "WinCallBack" indicandome que BOOL no puede convertirse en constaste, agradezco su ayuda
