But I am still wondering WHY the mask interferes with the enduser
inputing data to it?
I don't have an answer for that.
"Also, if the text evaluates as valid but in a different format you
can use the LostFocus () event to enforce the telephone format you
expect: 493.555.1039 => (493) 555-1039."
Ok, are you saying that after the enduser inputs the data and then
tabs to the next entry the data then becomes 'formated' or masked
in the previous entry or will BEEP if it is not correct?
Yes.
So how would i set something like that up in my code?
One example is where most Adobe products allow you to input numeric
values. Using their numeric input field, you could input values such
as "3.0123456789" and when you tab/LostFocus() or Enter/Return, then
the value is rounded to a certain value... in this case "3.012". In
addition, the numeric field allows you to enter values in different
measurement systems... if your preferences are set to inches, you
could enter a numeric value in points, centimeters or some other
measurement system if you know the code. For a more detailed
description of this, take a look at my StepField documentation:
http://developer.dreystone.com/stepfield.php
If a value inputted is invalid, such as "3.ab0", then a message
dialog appears in the Adobe products and forces the focus back to the
control which has the error. Adobe products are usually nice enough
to describe the range of acceptable values such as "please enter a
value between -600.0 and 600.0" whereas "3.ab0" is non-numeric and
invalid.
So back to the phone number issue... the simple solution would be to
call from the LostFocus() event a function to validate the phone
number and return false if it is not valid. Your code would look
something like this:
Sub LostFocus()
If Not ValidPhone(Me.Text) Then
MsgBox "Please enter a correctly formated telephone number."
Me.SetFocus
End If
End Sub
Very simple, but the problem with the above code is that the very act
of creating a MsgBox causes the LostFocus event to fire and for some
reason it triggers the LostFocus() event twice (some sort of
collision of events). Instead, what REALbasic does is put these
messages in the status bar at the bottom of the screen. To function
properly, the only method I have been able to use is to trigger a
thread which calls the MsgBox after a short period of time like 10 ms.
You could just as easily use a Beep and SetFocus (this will work
fine) but it may not be immediately obvious to the end-user. For
phpRegistration, I think that I had a static text message notifying
the user when they clicked the "Submit" button... this is OK too.
