Пишу программу калькулятор за основу взял программу из книги Ч.Петзолд(Програvмирование для Win95)
Столкнулся с такой проблемой создаю диалоговое окно и хочу с помощью переключателей(AUTORADIOBUTTON)
переключать калькулятор в разные системы счисления OCT DEC HEX.Как это лучше сделать подскажите в виде кода/совета.Читал несколько раз пробовал разные методы никак не пойму что нужно.
