Need help with formating a number

I need to format an 11 digit number like this 999-999-99-999 and display it in a label.  The formatting is just for display purposes. The number is stored without the dashes in the database. I've tried using String.Format but haven't had much luck. Any ideas?

Write some code to split your 11 digit string into 4 sep strings
abc-def-gh-ijk -> s1,s2,s3,s4
use the string.mid function (in vb)

then use string.format on those, adding dashes as necc.

You probably had problem with String.Format becauce you do not know of the backlash trick. When you want to force a specific character in the format, but a backslash in front of it:

String.format("{0:###\-###\-##\-###}",99999999999)

Thanks!  That is what I needed.

  Dim strSelectedParcel As String = String.Format("{0}-{1}-{2}-{3}", _
               btnTemp.Text.Substring(0, 3), _
                btnTemp.Text.Substring(3, 3), _
                btnTemp.Text.Substring(6, 2), _
                btnTemp.Text.Substring(8, 3))
