Witam.
Ostatnio napisałem swój pierwszy program okienkowy w C++, liczący potęgę wpisanej liczby, z możliwością resetu oraz zamknięcia.
https://imgur.com/a/VRy3Phb
Niestety napotkałem 2 problemy:
1. Podczas każdego wciśnięcia F5/debugowania, zwał jak zwał, wraz z okienkiem włącza mi się konsola cmd, a nie powinna. Jak się jej pozbyć?
2.Podczas kliknięcia przycisku "Reset" ustawiłem, aby textBox text zmieniał się na "0", a label na " ".
Chciałbym aby po ponownym kliknięciu w textBox to zero zniknęło i aby było puste pole do wpisania kolejnej liczby. Mógłby mi ktoś doradzić jak tego dokonać?
Z góry dziękuję za pomoc!
