Question

I need to have a string, based on an integer, which should always have 5 digits.

Example:

myInteger = 999 formatedInteger = '00999' 

What is the best way of doing this in classic ASP?

Answer 1

You can use string manipulation functions for this.

This assumes classic ASP with VBScript (original version of the answer).

Const NUMBER_DIGITS = 5  Dim myInteger Dim formatedInteger  myInteger = 999 formatedInteger = Right(String(NUMBER_DIGITS, '0') & myInteger, NUMBER_DIGITS) 

Here an optimized version, wrapped in a function, offering variable width padding:

Const NUMBER_PADDING = '000000000000' ' a few zeroes more just to make sure  Function ZeroPadInteger(i, numberOfDigits)   ZeroPadInteger = Right(NUMBER_PADDING & i, numberOfDigits) End Function  ' Call in code:  strNumber = ZeroPadInteger(myInteger, 5)
