TextBox Question - Only two hyphens but not adjacent.

[evanesce]

Hi.


I searched here and there but still can't find any clue for my question.
I think it's a very simple one but for me, it's not. : (

In the form, I want a textbox which allows only two hyphens, not adjacent.

For example, 000-00--0000 would be wrong but 000-000-0000 would be OK

How can I do this?
Any help would be greatly appreciated.

Could try an input mask. Review http://office.microsoft.com/en-us/ac...010096452.aspx

Thank you for your relply.
I have a textbox which users will input cell phone numbers. (I live in South Korea.)
If the numbers start with 011 or 019 or 017 or 018, its format would be 000-000-0000 or 000-0000-0000.
Otherwise, the numbers are supposed to start with 010 and its format should be 0000-0000-0000
I mean, I have to consider the number of digits.
Is there anyway I can do that without using input masks??

What about multiple boxes for the input and code the string together and insert the hypens then?

The input mask allows for an optional character entry as described in the link I referenced. Try: 0009-0009-0009;0;_
