You could create two textboxes with a label between them.

Or you could use a regular expression which will increase
performance than adding another text box.
--------------------------------------------

Dim objRegExpr

'Create an instance of the regexp object
Set objRegExpr = New regexp

objRegExpr.Pattern = "\[0-5]{3}-[0-5]{3}"

Case 48 To 57, 8, 13

Case 45 ^^

Case 46

Good control, but _NEVER_ use magic numbers!!! This is a very bad
practice. Instead, define constants or use the one from the .net
Framework, like

you can test the vanue of the text on the leave event of the textbox using
string functions
ex
select case true
case t.text.length = 7
t.focus
case not t.text.indexof("-"c) = 3
t.focus
case not isnumeric(t.substring(0,3))
case not isnumeric(t.substring(4,3))

.....

if the test is no to your liking display a messagebox, statusbar message ...
and put them back in the txt until they jump to your commands ;p

ps you can make it a bit easyer for them:
if the input is 6 long and numeric then add the - yourself

If you download the VB Resource Kit for .Net from Microsoft, that comes
with Component One studio which includes a masked edit box.
