Вызов COM-OLE метода с out param'етром при помощи Jacob. Возможно?
Есть метод getEntity http://vbamodel.narod.ru/AutoCAD/idh_getentity.htm в классе AcadUtility http://vbamodel.narod.ru/AutoCAD/idh_utility_object.htm
не могу правильно вызвать его под Java.
Работающий пример реализации getPoint http://vbamodel.narod.ru/AutoCAD/idh_getpoint.htm
1.
2.
3.
private Point getPoint(Variant point, Variant question) {
return new Point(Dispatch.call(this.createdFrom.toDispatch(), "GetPoint", point, question));
}
Полный код:
