I started to learn coding if you call it for c++ (windows forms). I created a button with a Fixed Text and a Button to Copy the text. What I need now is a "Add" button that adds alot of desired numbers and shows them in a second TextBox. But I want to add many numbers and it shows only one and there a Next button that when you click it it shows the next number on the list. I tried many things and searches but I failed, help would be appreciated.
