Pascal Fans,
With a Free Vision validator such as:
Field^.SetValidator(New(PPXPictureValidator,
Init('&&&-####', True)));
I'm getting a runtime error 216 when attempting to validate the field if it
contains invalid data. I also get a runtime error 216 if I tab into the
field and type an invalid character for the first position while the
previous contents of the field is selected. If I delete the previous value
in the field before typing an invalid first character, the runtime error
doesn't occur.
This is an example from Chapter 5 - Creating a data-entry screen in the
Turbo Vision Version 2.0 Programming Guide. Example source code is
attached.
