How to transform a date-string in classic asp

Question

I'm a little blockheaded right now…

I have a date string in european format dd.mm.yyyy and need to transform it to mm.dd.yyyy with classic ASP. Any quick ideas?

Answer 1

If its always in that format you could use split

d = split(".","dd.mm.yyyy")
s = d(1) & "." & d(0) & "." & d(2)

this would allow for dates like 1.2.99 as well

Answer 2

Dim arrParts() As String
Dim theDate As Date

arrParts = Split(strOldFormat, ".")
theDate = DateTime.DateSerial(parts(2), parts(1), parts(0))

strNewFormat = Format(theDate, "mm.dd.yyyy")

Answer 3

OK, I just found a solution myself:

payment_date = MID(payment_date,4,3) & LEFT(payment_date,3) & MID(payment_date,7)

Answer 4

This is a way to do it with built in sanity check for dates:

Dim OldString, NewString

OldString = "31.12.2008"

Dim myRegExp
Set myRegExp = New RegExp
myRegExp.Global = True
myRegExp.Pattern = "(0[1-9]|[12][0-9]|3[01])[- /.](0[1-9]|1[012])[- /.]((19|20)[0-9]{2})"

If myRegExp.Test Then
    NewString = myRegExp.Replace(OldString, "$2.$1.$3")
Else
    ' A date of for instance 32 December would end up here
    NewString = "Invalid date"
End If

I have my own date manipulation functions which I use in all my apps, but it was originally based on this sample:
