I just want to say, I have completed my first program using my own Classes. I have struggled to understand OOP firstly with RealBasic, then with PHP, and then with Xojo.
But I couldn’t make my latest program work, for various reasons (not the least that I am a self-taught “programmer”), so I decided OOP was the only way. It took ages to figure out what to do, and how to do it, but it was worth all the time invested, because the program now works properly!
