Ejemplo de propiedades AbsolutePosition y CursorLocation (JScript)
En este ejemplo se muestra cómo la propiedad AbsolutePosition puede realizar un seguimiento del progreso de un bucle que enumera todos los registros de un objeto Recordset. Se usa la propiedad CursorLocation para habilitar la propiedad AbsolutePosition estableciendo el cursor en un cursor de cliente. Corte y pegue el código siguiente en el Bloc de notas u otro editor de texto y guárdelo como AbsolutePositionJS.asp.
