Restricting input to integers, display with comma separators

Question

I'm using Acrobat 8 on a Macintosh. My question is very similar to the previous one about truncation. I have a small array that adds and subtracts fields, and sums them to totals. The following scripts restrict the data entry exclusively to numbers, but my problem is that it doesn't display my fields in Acrobat with comma separators, e.g., 123,456. Is there a better way of doing this, or is it just a matter of adjusting the formatting script?
Using a custom script under Format:
Custom Format script:
event.value = "(" + eventvalue +")";
Custom Keystroke Script:
event.rc = /^[0-9]*$/.test
(event.change);

I'm not aware of any cultures that allow multiple consecutive separators, and of course "en-US" certainly doesn't. I think you answer is just that TryParse isn't as smart as you would like it to be.
If you know how many digits there are after the decimal point, you could use ToString to convert the decimal back to a string and verify that it is the same as the original string. For example, if the string has a currency symbol, thousands separators and
two decimal places, you could use the following:
Dim result As Decimal
Decimal.TryParse(Me.tbxkWhCost.Text, System.Globalization.NumberStyles.AllowThousands _
Or Globalization.NumberStyles.AllowDecimalPoint Or Globalization.NumberStyles.AllowCurrencySymbol, Nothing, result)
If result.ToString("C2") = Me.tbxkWhCost.Text Then
'String is good
Else
'String is bad
End If
I realise that this doesn't work if you don't know what format the number will be in.
