What was your first coded software?

What was your first coded software?

I remember, i was 15 years old when i created my first software in visual studio. It was a very basic software with one text box and one button , the function of software was to show written text from textbox in a message form.

I learned too much from internet , especially from online tutorials, coding forums, ebook-s, and I'm still learning and coding in the same time.

What about you guys? Please share your experiences...
