if a string has letters, numbers, and other characters, such as "N23@xa1#P4a!", can the other characters be removed and the letters/numbers be listed in a multi-line textbox such as below;

N23
xa1
P4a

I've been messing around with InString and Mid functions, but cant come up with a practical way to do it.
I can easily remove the other characters from a string, but how to list the others is getting tricky.

I'm going to try Replacing the other characters with a KeyAscii Enter code and then send the string to the multi-line textbox. (not sure if that will work????)

Any other ideas?
