I'm having trouble in making an input box where I can limit the characters that can be inputted. Anybody have an idea how this can be done in Auto IT?
Specifically I would like to create an input field where the user would enter a MAC address. What I would like to do is to limit the characters that can be inputted to only HEX values (A-F and 0-9 as well as the - character). This is so that the user cannot input invalid characters. The program is going to be used by very non-technical people, so the idea is to remove as many chances for errors that we can think of. I would also prefer to limit the field to only 17 characters, so that there is only enough space to enter the MAC address with the - character as the separator.
Thank you all in advance for any suggestions!
