Padding Left Side Of Number - VB.NET


I have a database field to represent in fixed length - Say length (7). If i have a value "123" from database then i want to represent it with "0000123". Similarly for "1234", i want to represent it with "0001234". Can you please provide me simple function which will do this task in VB.NET ?

One method is using ToString with format string like "0000000" or "#0000000".  Alternatively, you could do this on the database end by converting the INT to varchar and then concatenting '0000000' in front of it and then taking the right 7 characters.
Dim i As Integer = 123

The VB.NET way more quickly adapts to numbers greater than 7 characters if you ever breach the limits of the 7 digits.  However, here is the SQL version (MS SQL example).
SELECT RIGHT('0000000' + CAST(123 AS VARCHAR(10)), 7);

If you are working with STRING values from the DB then use String.PadLeft() or String.PadRight().

Are those still around?  Nice suggestion, Idle Mind.  I use to love using those functions think was in MS Access then Microsoft decided to get rid of them for whatever reason.  Forgot they are now back, or maybe I was misinformed all these years. ;)
Hi milani_lucie,

I'm just providing some sample code to what Idle Mind suggested. I'm a little late in, but nevertheless, I still can assist.  :- )

mwvisa1: yes,  the pad methods are still around. :- ) The PadLeft and PadRight, actually replaced the LSet() and RSet() functions of VB 6.
Dim PadString As String = "1234".PadLeft(7, "0")
