Проблемы с использованием 2-х Unit
16.03.2009, 19:24. Показов 1118. Ответов 1
Есть 1 форма и 2 юнита. Unit1 основной, а Unit2 добавлен. К переменным Unit1 могу обратиться только так RJW->Xback, а на прямую не получается.
Другая проблема, система начинает тормозить при вызове методов т.е в пишу RJW-> [пауза] потом появляются методы. Как убрать тормоза.
