No offense, but I wouldn't do it that way at all (filters, that
is). Instead, I'd make an EditField subclass that implements a state
machine via the KeyDown() event. I'd also make two methods in this
class, Unformat(s As String) As String, and Format(s As String) As
String. In the GotFocus() event, call Unformat() on the existing text
to convert it into a string of only digits. Allow certain characters
in the KeyDown() event as discussed above, then call Format() in the
LostFocus() event to put the result back into the EditField in a
formatted form.
This is a lot more powerful and gives you the control over what
characters are allowed/not allowed; essentially, you make your own
filter to fit a specific purpose. Save the resulting EditField
(export the class) subclass somewhere, as you'll probably find
yourself using it in future projects! :)

And that works, except that the user must start the phone number
with the
"(" character. I would prefer it if the user didn't have to enter the
preceding "("--just the 10 digits themselves. I guess I'm asking if

any way to prepend a character to the mask output. I didn't see
anything in

I tried using the "C" switch, to make the "(" optional, but hat
didn't quite
work right.
I could validate and reformat the phone number when the user leaves
the
editField, but it sure would be nice to handle it automatically.
Any ideas? I think maybe I need some sleep.
