First of all hi, I hope I am posting in the right forum hehe.
Well, I am trying to write a small program that connected to an online database using mySQL. By any chance does any1 know what is causing it?
These errors come up when I try to press the add button to add new information to the database.
I can also post the code that is making the program crash too,
Thanks for any help!
