Currently I am doing this using the AskText dialog, but it is allowing entry of multiple letters, not just one character. I have tried limiting the string to one character in the declaration, as in:
Stating two characters so one will hold the null string character, but the dialog still accepts alot more characters that this. This method worked in InstallShield 5.
I realize I can always strip out the first character and do some error checking, but it would be better if I could eliminate possible user confusion.
