Hi, Richard.

In the attached example, you have a form with a textbox.
What it does:

1) it autocapitalises the text when it changes

2) print the ascii code of the pressed key

3) it doesn't allow "W" or "w"

4) when you press space bar it becomes an underscore

all is commented in the code, so you see what does what.

I think it will not be difficult for you to manage Mc or O'
using string manipulation functions.
