Я хочу открыть 2-ю вкладку, когда нажму кнопку ok в первой вкладке mfc C++ 2015.

---

я написал программу, которая содержит 2 вкладки sample tab1 и sample tab 2. я использовал mytabctrl.h и mytabctrl.cpp чтобы построить вкладки. Теперь я хочу сделать так, чтобы при нажатии кнопки ok в 1-й вкладке i-2 sample tab1 открывалась 2-я вкладка i-e sample tab2. как это сделать нужна помощь.

Что я уже пробовал:

заголовочный файл главного диалога-maindialog.h
