I ran into an interesting problem with a Vista sidebar calendar gadget. It seems that it is not exactly trivial to find out interesting NLS data like localized month names, first day of week, etc. from JScript.

Eventually I found a workaround for some of the data. VBScript has MonthName, WeekDayName and WeekDay functions that can be used for some of the data I was looking for. These can be wrapped in VBScript functions which JScript can then call from the same page. I calculated FirstDayOfWeek information by using the WeekDay function for a known date.

These are the helpers that I ended up with:

<script language=”VBscript”>

‘ Helper functions so we can do this in JScript as well

Function MyMonthName(month)

MyMonthName = MonthName(month)

End Function

Function MyAbbrevMonthName(month)

MyAbbrevMonthName = MonthName(month, True)

End Function

Function MyDayName(day)

MyDayName = WeekDayName(day)

End Function

Function MyAbbrevDayName(day)

MyAbbrevDayName = WeekDayName(day, True)

End Function

‘ Get First Day of Week where 1 is Sunday, 2 is Monday, etc.

Function FirstDayOfWeek()

Dim MyDate

MyDate = DateSerial(2002, 9, 1) ‘ A Sunday

FirstDayOfWeek = (9 – WeekDay(MyDate, 0))

if FirstDayOfWeek = 8 then FirstDayOfWeek = 1

End Function</script>

Unfortunately some items like Shortest Day Names and Month/Year patterns can’t be retrieved this way, but I was able to solve most of my problem. The attached CalendarData.html uses these helper functions to dump the values I was interested in using both VBScript and JScript.

I also embedded the HTML here, so here’s the output, hope this is interesting:

I just saw this interesting exchange on an internal discussion list, and thought I’d pass it on: From:…
