Hi Daryll,
I'm not sure I'm getting what your problem is.
sub beautify_input
{
$foo = $Window->MyField->Text ();
$bar = sprintf ("%03d", $foo);
return $bar;
}
is one of 1001 ways to turn 1 to 3 digit numerical input into exactely 3
digits with leading zeroes. It does not do any validation (is $foo numeric,
is it more than three digits ...), but is that your issue at all? Or do you
wonder where to put the &beautify_input call, ie, when to intercept user
input?
