I want to create a function which accepts's key presses and displays them in a rectangular box (field).
I tried a logic which failed because a char cannot be converted to a string.
here's the logic.
char str*;
str = 'a' + event.keyboard.keycode - 1;
Here's my updated version but still not working. showing signs of memory leak, Please Help!
